PERSONAL PROTECTIVE EQUIPMENT (PPE) Safety at work should always come first, and employers have duties concerning the provision and use of personal protective equipment (PPE) at work to meet the requirements of the Personal Protective Equipment at Work Regulations 1992. These rules apply if you’re self employed as well, so you’ll probably need to use some type of personal protective equipment (PPE) in your job. PPE is equipment that will protect the user against health or safety risks at work. It can include items such as safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses. It also includes respiratory protective equipment (RPE).
tOp tips Choose products which are CE marked in accordance with the Personal Protective Equipment Regulations 2002 – suppliers can advise you
Choose equipment that suits the user – consider the size, fit and weight of the PPE. If the users help choose it, they will be more likely to use it
If more than one item of PPE is worn at the same time, make sure they can be used together, eg wearing safety glasses may disturb the seal of a respirator, causing air leaks
Never allow exemptions from wearing PPE for those jobs that ‘only take a few minutes’

Engineering Joists Buildings that incorporate timber ‘I’ joists (Engineering Joists) allow for more flexible drilling of holes for pipe work. ‘I’ joists incorporate 38mm knockouts (dependant upon the manufacturer), and also allow for larger holes to be drilled through the joists.
The same rules apply when drilling through ‘I’ joists as for drilling traditional joists where horizontal measurements between holes are concerned. However, as the strength of ‘I’ joists is in the flange (see fig. 3), these joists are not suitable for notching, as notching the flange will damage the structure of the joist which will have a detrimental effect on its strength. The size and positioning of holes drilled through ‘I’ Joists must be in accordance with fig. 3 (right).

HELP YOUR CUSTOMERS SAVE WATER & REDUCE THEIR HOUSEHOLD BILLS Over 40% of households in the UK now have a water meter fitted and the bathroom is a hotspot for water use. There are now a whole host of bathroom products you can recommend which don’t cost the earth, but will help your customers save water….and money.
Dual-flush toilets give your customer the choice of how much water to use, usually either 6 or 4 litres per flush, which is a massive saving on the older-style systems which can use up to 13 litres.
You can install low-volume baths that have internal contours so that they use less water, but still give the feeling of a proper soak
Flow regulators can be fitted, or even retrofitted, to basin and bath taps and showers to control water usage
A low-volume bath and dual-flush toilet, like these from Twyford, can save your customers a lot of water and reduce household bills
Twyford e500 Flushwise®, Rimfree® toilet
DID YOU KNOW? One third of the water we use every day is literally flushed down the loo. Waterwise recommend installing toilets with a dual-flush mechanism. Why not try a Twyford Flushwise® 4/2.6 litre dual-flush that can save up to 60% compared to a standard 6 litre flush. If required the flow can be adjusted to 6/4 litres.

BAthROOm instALLAtiOn tips When it comes to installing a bathroom, you naturally want to make sure of a perfect job every time. Here are Twyford’s top tips:
1
Most importantly, remember to read and understand the instructions fully prior to starting the fitting, as this avoids unnecessary and costly mistakes!
2
Check all of the connections on the cistern for the inlet and outlet valve, and the connecting rods from cistern to pan, are all fully tightened to prevent leaking.
3
Fill the cistern full of water prior to installation to check for leaking on the seal. Adjust the seal as required.
4
Some bath legs will come pre-assembled, but they will always need the feet adjusting to the height required. It’s imperative to get a good, level finish and ensure the legs and feet are set to the right height.

Keep Up With the tRenDs AnD sUppORt YOUR CUstOmeRs Part of your job will involve keeping up with the latest trends and technology, even for everyday products like toilets. It’s amazing how much they’ve developed over the last few years. For example, most manufacturers now offer toilets with no rim, following Twyford’s introduction of Rimfree® technology to the UK. The real selling points of rimless toilets are the added hygiene, because there is nowhere for germs to hide and multiply, and the fact that they are much easier to clean. The bonus for you is that there’s no special plumbing needed to install a rimless toilet, so you can offer the benefits without the hassle.
Another growing trend is wall-hung toilets, especially for en-suites and cloakrooms where space is tight. That’s because wall-hung sanitaryware can help make a small space look larger, as you can still see the floor underneath. It’s also a lot easier to clean the floor below if everything is raised, more hygienic all-round. Twyford’s e100 square wall-hung Rimfree®, Flushwise® toilet
Being able to discuss trends with your customers gives you a chance to showcase your breadth of knowledge, giving them full confidence in your installation job and maybe leading to them recommending you to a friend.

EXPLORE THE POTENTIAL OF BIOMASS Biomass boilers are an efficient and sustainable form of off-gas heating, explains Anna Wakefield, Marketing Manager for Grant UK. Over the last few years there has been a marked rise in the installation of renewable technologies, such as biomass boilers. Biomass is a reliable, low carbon fuel, so more rural property owners are therefore opting for this green source of heating.
Additionally, biomass boilers can be eligible for the Renewable Heat Incentive (RHI), as long as the product and importantly, the installer (when applying for the domestic tariff) are Microgeneration Certification Scheme (MCS) approved. This scheme financially rewards the end user for generating and using renewable energy to heat their building.
Biomass boilers
Biomass boilers are fuelled by wood, and so burn wood pellets, chips or logs to provide
environmentally friendly heating, whether for a home or commercial site. Spira

The fuel is made using waste products from sawmill industries or wood from managed forests (where trees are planted to replace the ones cut down).
Increasingly, the most popular type of fuel is wood pellets.
Increased demand With the demand for biomass heating increasing, we feel it is important to continue to develop our product offering, which now includes several boiler models, bulk wood pellet stores, outdoor boiler pods, and vacuum systems, all of which are designed to make the lives of the end user and installer easier. We combine years of experience gained in manufacturing off-gas heating solutions with installer feedback, to produce highly efficient products. Our pioneering biomass boiler, the Grant Spira, is a unique condensing appliance that burns wood pellets.
It utilises the exclusive Grant turbulator bafďŹ&#x201A;e system, used in our award winning Vortex oil-fired boilers. Many modern standard efficiency pellet boilers lose up to 20% of the energy produced through waste gases exhausted by the ďŹ&#x201A;ue system, but the Spira has this secondary heat exchanger, designed to capture lost heat energy. Available in various outputs from 5 to 36kW, the range combines easy installation with straightforward daily operation and low maintenance. Installations up to 72kW can also be accommodated by utilising two boilers (separately ďŹ&#x201A;ued) with a central hopper / twin auger arrangement. Using two boilers to achieve higher outputs is very cost effective. When the boilers are combined, their precise electronic burner controls allow both units to modulate as one, down to just 25% of maximum load when the full output is not required. This, along with the extremely high efficiencies achieved, makes the Spira a unique option when considering a biomass boiler.
The Spira range also welcomed a new indoor model this year, featuring a 5 to 18kW output. Importantly, this model will not only be exempt under the Clean Air Act, but listed on the MCS (Microgeneration Certification Scheme) database.
Wood pellets We also manufacture wood pellet bulk stores in various sizes from 500kg to 6 tonnes. While wood pellets can be bought in bags (typically around 10 to 15kg), if space is available, a bulk store can be installed which can directly feed (by auger or vacuum system) the intermediate Grant pellet hopper supplied as standard with the boiler. This allows end users to buy pellets in large quantities, which is more cost effective.

One of our latest products to be unveiled is the Grant SpiraPod, which was developed to help increase the options when siting a Spira boiler.
...we support fully qualified installers with an accredited scheme called G-One, as well as several free of charge product courses. With a lack of easily accessible information about biomass heating online, we were inspired to create the Grant Biomass Forum, www.grantbiomassforum.com where trade professionals can find answers to technical queries and have discussions with others. Not only does it enable consumers and installers to educate themselves, but also gives potential customers a gateway to finding knowledgeable, accessible installers in the area.
YouTube channel This purpose built external housing solution is suitable for all weathers and is designed to shelter the Spira from the elements. It includes an integrated 190kg pellet store and it neatly houses both the Grant wood pellet vacuum and sealed system kit too.
Support With so many developments in the renewables market, we understand the importance of offering comprehensive training and support with products. Furthermore, we firmly believe improving knowledge in the marketplace will encourage engagement and uptake of the technologies. For instance, we support fully qualified installers with an accredited scheme called G-One, as well as several free of charge product courses. The training is accessible nationwide, with academies in Wiltshire and North Yorkshire.
We have also produced a number of short films which are available on the ‘myGrantUK’ YouTube channel. The first series comprises three bite size modules specifically aimed at the end user. The Grant Guide to Biomass explains in a clear and entertaining format what biomass is, the different fuel types that are available, exactly why biomass is carbon neutral and how it is used in heating systems. A second film, The Grant Guide to the Domestic RHI tackles the Renewable Heat Incentive, how payments can be accessed and what paperwork is required to claim payments. For those end users seriously considering installing the technology or who have already purchased a Grant Spira, there is also a Guide to the Practicalities of Owning a Biomass Boiler.

THINKING BEYOND THE COMBI BOILER When consulting homeowners over boiler replacements, installers can offer more value by addressing the full heating picture, says Christian Engelke, technical director at Viessmann. For most installers, boiler retrofit business takes a fairly standard shape. The customer calls in a panic. They don’t care about some grand heating system solution; they just want the hot water back on by this time tomorrow. The installer saves the day and wastes no time in fitting what they know. More often than not, for the average UK home, the default response is a combi boiler installation, as clearly illustrated by market figures; more than 75 per cent of total wall-mounted condensing sales are combi boilers and 10 million have been installed since 2003. We suggest that installers are missing a trick. Distress purchase behaviour aside, consumers are waking up to energy efficiency in the home, the availability of renewable energy solutions and the benefits of integrating different heating technologies. We are much less tolerant of ‘making do’ these days; we’re less likely to replace like with like or embrace a combi boiler if it means running out of hot water every time the in-laws come to stay, or reducing our options for energy efficiency in the future.
Despite the ease of the combi solution, the boiler is just one piece of the jigsaw. The heat generator is not considered in isolation anymore. Installers who act more as home energy consultants will sell additional products and services (complementary to the well understood boiler), protect themselves against fly-bynight individual technology ‘specialists’ and attract enduring, positive reputations. Installers need to lay the foundations for a renewable-friendly, future-proofed infrastructure.

The homeowner is sold on the extra space and promise of hot water on demand. Yet there are system efficiencies, cash benefits and greater hot water comfort – more of it and more quickly – to be had from a systems approach and by converting to a four pipe system. The dangers often start when the new combi output is sized for a higher hot water flow rate, which leads to an increase in energy use, or based on price sensitivity, which means that the boiler has a lower output and flow rate, resulting in the end user losing the flow rate they were accustomed to. If the replacement boiler output is the same as the previous one, then something has to give.
DID YOU KNOW? People wrongly believe that cylinders lose energy quickly. Yet replacing an old system boiler and cylinder with new can result in 30 per cent energy savings.
The roughly 1 kW per day energy loss from a cylinder translates into just £1 a month, yet £30 can be saved by upgrading a home’s cylinder (on top of the £300 saving from installing a new condensing boiler). This is why we supported the case for including hot water cylinders as a measure in the Green Deal Home Improvement Fund. The four pipe system, as used by Viessmann, allows the boiler to discriminate between the DHW and heating circuits, serving each circuit with separate flow and return pipes. This means energy cut-off valves are no longer required. In addition, cylinder overheat thermostats are not required as a DHW sensor fitted to the cylinder controls temperature and satisfies the necessary G3 building regulations. This approach allows for lower flow and return temperatures for heating, allowing the boiler to condense for around 70 per cent or more of the time, compared to a standard installation with

The additional benefit of installing a four pipe system is being able to specify a lower output, more affordable boiler. In a normal S or Y plan system the boiler is typically oversized by 10-30 per cent (or 6-10 kW) to cater for the hot water demand.

Paving the way for solar Solar is no longer purely about the environment. Not only does it provide hot water for free, the government pays out attractive sums for heat generated under the RHI schemes. The payback period, which, depending on the property, can be as low as around 11 years, is not the issue for homeowners that it once was.
With hot water energy savings of up to 60 per cent per year, we believe that all new boiler installations should be made solar thermal ready. There is no better point at which to do this than when fitting a replacement boiler.
The installer will already be working in key areas such as the loft anyway and minimal additional work is required. Apart from the skills associated with installing the panels on the roof, the bulk of the tasks – working with fittings, hydraulics and flow rates for example – will be familiar territory. A solar controller often needs to be added which is plugged into the solar pump station in the airing cupboard or loft. The boiler is swapped for new, ideally in the four pipe configuration and then linked to the cylinder. For solar, the cylinder needs to be replaced to a twin coil cylinder which, in most cases, can sit in exactly the same space. Even if the homeowner is not considering integrating solar at this point, it is still a sensible call to specify this type of cylinder for the future, to avoid having to pay twice for a new cylinder. A system approach also prepares the property for integration between the boiler and other renewable heating products, particularly heat pumps. We see the trend for hybrid systems growing in the future. Who knows how difficult it will be to convince customers to lose the airing cupboard space they once gained, in order to access future energy saving options, unless we prepare homes for the future, now?

TOPTECHNOLOGY Hydraulic balancing Vitoflow FOR ALL HEAT GENERATORS UP TO 150 KW Automatic hydraulic balancing of radiator circuits can now be implemented with all Viessmann heat generators up to 150 kW. No specialist knowledge is required.
VitOFLOW Hydraulic balancing - simple, quick and automatic The hydraulic balancing of a heating system is necessary to ensure that all radiators in the system are supplied with the exact amount of heat. This requires the flow rates in the heating circuit piping, the output of the circulating pump and the heating curve of the heat generator to be adjusted very precisely. Subsequently, it is ensured that no room is under- or oversupplied with heat and that the energy is used in the most efficient way. The energy efficiency of a heating system can be increased by up to 15 per cent – therefore, hydraulic balancing is one of the most efficient methods of reducing heating costs and CO2 in the long term. However, hydraulic balancing is often not done because it is a complex procedure and requires a lot of time as well as expert knowledge. An innovative solution is provided by the automatic hydraulic balancing system, Vitoflow. Vitoflow simplifies and accelerates the execution of hydraulic balancing and is one of the most precise and reliable methods on the market.
ENERGY CONSUMPTION REDUCED BY UP TO 15 PER CENT Balancing optimises the settings of integrated pumps and the heating curve, ensuring that all radiators are supplied with the appropriate amount of heat for the respective room. This can reduce energy consumption by up to 15 per cent, also resulting in a lowering of CO2 emissions. TIME SAVED THROUGH EASY PROCESS The time required for determining the default settings on a system comprising ten radiators is barely 30 minutes, in other words a fraction of the time usually taken. Apart from a laptop, contractors only require the Viessmann service case with wireless actuators, an extension kit (depending on heat generator and heating system) and Vitosoft 300 service software.

CAPILLARY JOINTING An important part of your plumbing training is the correct installation of copper pipework. If it’s your ambition to become a professional plumbing and heating engineer, you will need to master a range of practical skills, including: measuring, cutting, jointing and bending copper tube.
There are 4 essential stages in the jointing process:
1. 2. 3. 4.
PREPARATION FLUXING HEATING REMOVING FLUX
Capillary jointing has been part of the professional plumber’s repertoire for many years and will continue to be so. It is important to learn the correct procedure that will ensure your soldered joints are perfect every time. Getting into good habits right from the start of your apprenticeship will see you successfully through your plumbing career.
Getting it right Plumbing and heating systems make full use of the exceptional performance of soldered joints. ‘Soldering’ is a simple and very effective method of jointing copper tube, giving durable and reliable pipework installations. Correctly made, a soldered joint will help to give installations long service lives. continued>>

HIP BOOK 2015-16 | COPPER PIPEWORK
The steps required to make a correct soldered joint are very simple, but it is important not to cut corners.
1
pRepARAtiOn
Cutting the copper tube is the first step, followed by deburring the inside and outside edges of the tube end. It is vital that burrs are removed as they can disrupt water and gas flows and, in some cases, affect the integrity of the joint. The surfaces that are to be joined need to be clean to ensure that a sound joint is made. An abrasive pad should be used to remove any dirt or oxide layer from the tube end and the internal surface of the fitting. Steel wool should NOT be used as there is a possibility that small steel particles may get embedded in the copper, which can lead to problems when the pipework is in service.
2
FLUXing
Flux enables the solder to wet, adhere to and alloy with the surface of the copper, forming a watertight joint. For plumbing applications fluxes of the zinc-chloride or zinc-ammoniumchloride types are used. Extreme care should be exercised when using ‘self-cleaning’ fluxes. A thin layer of flux should be applied to the jointing surface of the tube. The tube is then inserted into the fitting up to the tube stop, whilst twisting the tube round so that the flux is spread across the fitting surface. Any excess flux should be removed. Flux is not applied to the jointing surface of the fitting because there is the potential for the tube, when it is inserted into the fitting, to push flux inside the pipework.
3
heAting
Heat is usually applied with an LPG blowtorch and the flame needs to be kept moving around the joint, as overheating one spot can lead to charring of the flux, affecting its performance. For an integral solder ring (ISR) fitting, once it has reached the required temperature, the solder will melt and a bead will form in the mouth of the fitting, all the way around. The joint is complete and there is no need for any additional solder to be fed into the joint. For an end-feed fitting, the solder is brought into contact with the heated tube and, if it melts, then the flame is withdrawn and the solder flows into the joint, forming a bead in the mouth of the fitting. Should the solder not melt on contact with the tube, further heating is required. For drinking water pipework only lead-free solders can be used as leaded solders are NOT allowed. Integral solder ring fittings contain a lead-free solder, EN 29453 alloy 23. This solder melts between 230ºC and 240ºC and can be used on all copper pipework applications.
COPPER PIPEWORK | HIP BOOK 2015-16
NOTE ON PLASTICS COVERED TUBE
4
RemOVing FLUX
When the joints are completed, with a bead of solder showing in the mouth of the fitting, it is important to allow them to cool so that the solder has a chance to solidify. Moving the assembly before the solder sets can affect the integrity of the joint, perhaps leading to leaks. At this stage it is vital to remove any flux residues on the outside and inside of the pipework. Fluxes on the outside can be removed with a damp cloth. Fluxes on the inside should be removed by flushing the pipework with fresh cold water as soon as possible. Flushing will remove waterbased fluxes, however grease-based fluxes will require flushing with hot water. If fluxes are not flushed away, corrosion damage can occur during the service life of the installation.
If a ‘self-cleaning’ flux has been used, flushing of pipework is extremely important.
Capillary fittings can be used in conjunction with plastics covered copper tube. For this, the plastic covering is cut lengthwise down the tube so that about 100mm of copper is exposed. The joint is made in the same way as described above but extra care is needed to avoid burning the plastics covering and allowing flux to become trapped between the copper and the plastics covering. Once the joint is made and has cooled, and fluxes removed, the plastics covering is folded back into place and spirally wrapped with a suitable tape, selfadhesive polythene or PVC. The tape should cover the last 25mm of intact plastics covering and at least 25mm of immediately adjacent bare copper tube. The capillary jointing system has been gradually evolving for over fifty years, and we can now say that - in the hands of the professional plumber - it is completely reliable. Following the procedure set out above, you can ensure that each and every one of your soldered joints will be to the highest standard, satisfying both you and your customers.

COPPER INITIATIVE SUPPORT FOR YOUNG PLUMBERS Copper has long been the material of choice for plumbing engineers. The reliability, durability, versatility and good looks mean that copper reflects the professionalism of the installer. It is essential that each new generation of plumbers is equipped to design and install copper to very high standards. As part of our commitment to education, Copper Initiative sponsors the National Apprentice of the Year skills competition. We believe that people should be encouraged to develop skills that will equip them to develop a career in the plumbing industry.
Copper Initiative has a wealth of information available on how to correctly design and install copper pipework systems. Our Copper Club packs can be obtained simply by completing the on-line form on our website: copperplumbing.org.uk
INSTALLATION TIPS is the technical manual that covers just about everything you might want
to know about copper pipework systems. Easy to follow guidance is given on many topics including jointing techniques, bending, pipe sizing for both water and gas installations, the correct choice of solders and fluxes, pressure testing and locating pipework in suspended floors. COPPER THE MODERN SOLUTION describes the two flame-free jointing options for copper – push-fit and press fittings. For those places where you don’t want to use a flame, in roof spaces with combustible materials for example, push-fit and press fittings both offer alternatives to soldering. COPPER PIPEWORK COMPENDIUM CD, incorporating Make the Right Start, brings together all of the educational information produced by Copper Initiative. In addition to the many pdf’s of the literature the CD contains webcasts (narrated PowerPoint presentations) and a number of question & answer sections where students can test their knowledge.

THE BUZZ ON ELECTRIC Alan Clarke, technical support manager at Heatrae Sadia, tells us more about electric wet central heating boilers and explains what the Ecodesign and Energy Labelling Directives (generally referred to as the ErP Directive) mean for the market. Electric heating is an ideal solution when mains gas isn’t available, or it isn’t a practical option due to installation or maintenance issues.
Compared to mains gas, there are generally few restrictions on the supply of electricity, and there aren’t any flueing, condensate drainage or plumbing issues to consider.
Electric wet central heating Fortunately, the electric heating market has moved on from the inflexible, largely uncontrollable night storage heaters that electric heating was once associated with. Heaters which store energy overnight and release it during the day (whether or not it’s needed) are not an appropriate solution for today’s consumer – and so innovative, sophisticated,
controllable products that provide heating and hot water when the end user wants it have been developed. One of the main advancements has been the introduction of electric wet central heating flow boilers. Compact, wall hung and efficient, electric wet central heating boilers are used in conjunction with conventional wet radiators or underfloor heating systems, and provide central heating on demand, when it’s actually needed. They are controlled and operated by a programmer and thermostat, working in a similar way to a gas fired boiler. Our Amptec electric boiler even modulates in the same way as a gas boiler, improving running efficiency. continued>>
A Megaflo. For every need. Today’s modern lifestyles mean we all have greater demand for hot water and how we use it. At home, and in the workplace, there’s a growing need to service multiple users at the same time, whilst striving for greater performance and reliability that’s affordable and low in environmental impact. Driven by these needs our team at Heatrae Sadia launched the groundbreaking Megaflo cylinder back in 1989 and as our customers’ needs have grown so has the Megaflo product family. UK designed, engineered and manufactured to exacting detail, Megaflo comes in over a hundred variants, all with an ErP rating for energy efficiency. Offering a product truly tailored around your individual needs.

HIP BOOK 2015-16 | ELECTRIC WATER HEATERS
To supply hot water to all-electric properties, electric boilers can be teamed with direct cylinders. High-performance unvented hot water cylinders, which are fed directly from the cold water mains, will provide the end user with powerful showers and fast filling baths.
Our Megaflo Eco can deliver up to 72 litres per minute of hot water, and there’s no significant difference in performance if more than one tap or shower is used simultaneously (depending on the mains water pressure and flow rate coming into the property).
Product selection
Most consumers will want an electric boiler to be as comparable to a gas boiler as possible, not only in terms of user benefits like controllability but also operating life. There are various electric boilers on the market, but it’s important to remember that they differ in terms of cost, longevity and quality. Low-cost electric boilers will quickly prove to be false economy, as after just a few years it’s likely they will either need to be repaired or replaced. Some electric boilers can have an operating life similar to a traditional cast iron gas boiler (which can boast a lifespan of around 25 years). High-quality products that last might cost more initially, but will save the customer money in the long run, while also providing peace of mind. To ensure that our Amptec boilers have a long operational life, several key features were designed into the product. For example, we use solid state technology for the switching of the heating elements to ensure a much longer switching life compared to what is achievable
using conventional electro-mechanical devices such as relays and contactors. We believe that only solid state technology is suitable for the typical switching life required for a long-lasting electric boiler, and we avoid using mechanical relays to switch the heating elements on and off. In addition, the heating elements used in Amptec are designed to run at low Watts density, which is essential to prolong the boiler’s life, and we chose copper sheathed elements, as in this particular application they last longer than other materials.
ELECTRIC WATER HEATERS | HIP BOOK 2015-16
In addition to Amptec, Heatrae Sadia has also combined an electric boiler and a hot water cylinder into a ‘one box’ solution. Electromax provides full wet central heating and unvented domestic hot water from one compact unit. Factory assembled and tested and pre-plumbed, it’s really simple to install.
Efficiency, Ecodesign and Energy Labelling Since September 26 this year, electric boilers of up to 400kW (along with other types of space and combi space heater) have needed to meet minimum energy performance criteria in order to be legally placed on the EU market, in accordance with the Ecodesign Directive (commonly referred to as the ErP Directive). And through the complementary Energy Labelling Directive, which has applied to space heaters and combi space heaters of 70kW and below (including electric boilers) since the same date, electric boilers are now supplied with energy labels, similar to those seen on fridges and washing machines. Manufacturers must meet the requirements of the regulation (conforming to the energy and environmental standards) in order to legally place their product on the market in the UK and other countries in the European Economic Area. Due to the ‘fuel factor’ that is added to all electrically powered products, electric boilers are (at the time of writing) likely to have a D rating. It is important to remember – and to communicate to customers – that this is because the generation of electricity is currently viewed as carbon intensive and electric heating products are therefore penalised. However, we believe this is a short-sighted view, as at the
point of use electric products are very efficient – Amptec, for example, is over 90 per cent efficient.
...the heating elements used in Amptec are designed to run at low Watts density, which is essential to prolong the boiler’s life... Direct electric cylinders are also affected by Ecodesign and Energy Labelling; from September 26 2015 water heaters with a rated output of up to 400kW and hot water storage tanks with a storage volume of up to 2,000 litres have needed to meet minimum energy performance criteria, and those with outputs of up to 70kW and storage volumes of up to 500 litres have required an energy label. All direct electric water heaters are likely to be in the C category, again due to the ‘fuel factor’ applied to electrically powered products.
The electric heating market has been revolutionised by electric wet central heating boilers. Flexible, controllable, simple, cost-effective to install, low maintenance, they offer a viable alternative when mains gas isn’t an option, and are increasingly being specified as the preferred choice for urban high-rise developments.

KNOW YOUR FITTINGS There is a huge selection of plumbing fittings available to today’s plumber. Each type of fitting has its advantages and disadvantages, and it’s important to know what these are! Other advantages include the fact that this is a heat-free jointing method so there is no need for a hot works permit and costly additional insurance, no carbon deposits or reduced risk of corrosion. The bore of the system is exceptionally clean so requires less flushing, and there are no expensive or specialist tools needed to make the joint. Some push-fit joints are also demountable so joints can be broken and remade, or fittings reused.
How push-fit fittings work
PUSH-FIT FITTINGS These are fittings where the only jointing action required, is the push of the pipe or tube into the fitting with no additional processes needed to make the joint. The main advantage of push-fit systems is speed; the installation time is significantly reduced.
Each brand of push-fit fitting works slightly differently so you should always read the manufacturer’s instructions for the type of fitting you are using.

But the two things nearly all push-fit fittings have in common is the use of an ‘O’-Ring to make the seal between the tube / pipe and body of the fitting and the use of some form of grab ring to hold the tube / pipe in place.
The golden rule for push-fit fittings: Protect the ‘O’-Ring. Good tube / pipe preparation is vital to ensure that tube ends are clean, free from damage, cut square and have no burrs. Support liners must be used when installing PEX or PB pipe, or for 10mm copper tube and the support liner must be to the specification of manufacturer of the pipe / tube. Keep the fittings stored in their bag until point of use, so that the ‘O’-Ring does not get contaminated or the silicon lubricant dry out from being exposed. When inserting the tube into the fitting use a slight twisting action and keep the tube as parallel as possible to the fitting body. To ensure the tube is fully inserted into the fitting it is good practice to mark the tube with the socket depth so that you can check this corresponds with the mouth when the joint is made.
This multilayer tube bridges the gap between plastic and metal plumbing systems combining many of the advantages from each: Retains its shape once formed 40 per cent fewer fittings required on an average installation Lightweight and easy to handle Requires less clipping Offers tight bend radii of 4x tube diameter Low scrap value making it undesirable to thieves Resistant to corrosion Highly cost effective
Using the right support for the new flexible metal tube is critical - ensure you’re using the TectSEAL!
DID YOU KNOW? There is now multilayer tube available in sizes 15mm & 22mm for use with Tectite push-fit fittings. Flexible metal tube PE-Xc Aluminium PE-Xc
DID YOU KNOW?
There are different cutter wheels available for cutting different types of tube. Carbon steel tube is substantially harder than copper tube and using the wrong cutter wheel will result in extra time spent deburring the tube end.
FITTINGS | HIP BOOK 2015-16
The golden rule for press fittings: As with all fittings that are dependent on an ‘O’-Ring to make the seal, the critical thing is take all necessary steps to protect the ‘O’-Ring. Just like push-fit fittings, good tube / pipe preparation and keeping the fitting in the packaging until point of use is essential.
PRESS-FIT FITTINGS Press-fit is a relatively new jointing technique that uses force applied to the fitting by a press-tool to compress the fitting onto the tube with an ‘O’-Ring providing the actual seal. Press-fit fittings generally require more time than push-fit fittings to install, but they are still much faster than traditional techniques like compression or solder joints and like push-fit systems they offer a heat-free jointing method. This means no hot works permits, no carbon deposits, less flushing as the bore is very clean with no flux or solder residues. Press-fit joints are non-demountable but you can lay out all the pipe work for positioning first and then go around and make the joints with the press tool after. Many brands of press-fit fittings offer ranges for specialist applications, such as solar installations or above ground 2nd and 3rd family gas installation pipework. Recent advances mean that there are now press-fit fittings available in PVDF and Brass for use on multilayer pipe in sizes 14mm to 75mm.
To ensure the tube is fully inserted into the fitting it is good practice to mark the tube with the socket depth so that you can check this corresponds with the mouth when the joint is made. Make sure that you are using the correct type of jaws or sling-jaws for the brand of fittings that you are installing ensuring that they are compatible with the press tool you are using. Check the tool and fittings manufacturers guidelines if you are unsure. The final golden rule is to use the press tool in accordance with the tools instructions keeping it at a 90° angle to the fitting and making sure that it is fully supported throughout the pressing cycle.
And finally... No matter which type of system you are installing, you should always perform thorough system testing before any plumbing system is commissioned. Check out pegleryorkshire.co.uk

PLASTIC PUSH-FIT THE MODERN SOLUTION TO HOT & COLD WATER SUPPLY Plastic push-fit plumbing systems for hot and cold water services were developed by Hep2O here in the UK during the late 1970’s. Subsequent years have seen them steadily increase in popularity amongst professional plumbers and installers – largely as a result of a growth in awareness of the obvious benefits they offer. Plastic plumbing technology started to be taken seriously in the 1990s when availability became more widespread. A significant boost resulted from the uptake in under floor heating Hep2O Polybutylene pipe comes off the coil straight. (Pictured here with less flexible PEX pipe)
systems which mainly utilise plastic pipework. Another important development in explaining the increased interest in plastic pipe was the huge take-up of manufactured joists and I-beams for intermediate floors. In fact, it has been suggested that when it comes to fitting pipework through an I-beam floor, using plastic is around fifteen times faster than using rigid metal!
The principal of push-fit fittings A number of different manufacturers’ systems are now available but they all share a similar operating principle: The pipe is cut to length with an appropriate pipe cutter and a pipe sleeve is inserted into the pipe end. This is an essential part of the technology as it keeps the pipe end rigid and circular. The pipe is then pushed into the fitting, passing through a metal grab-ring and an O-ring. The grab-ring secures the pipe and prevents it ‘blowing out’ under pressure and the O-ring provides the leak-proof seal – and of course modern plastic fittings are equally effective when joining either copper or plastic pipe. Subsequent demounting is achieved by releasing the grab-ring and withdrawing the pipe. continued>>

Plastic push-fit systems are now commonly specified by RMI plumbers across a wide range of domestic and commercial applications. In fact they are so successful that 90 per cent of all new houses constructed in recent years use plastic systems throughout their entire hot and cold water supply and central heating systems.
BeneFits LOWER COST IN USE The reason for the growth in popularity of plastic systems lies in the impressive list of benefits they offer over the more traditional rigid systems:
1 Plastic pipe is very flexible and can be ‘cabled’ in a similar way to electrical wiring, thus cutting down on the number of joints required
2 Fewer joints means less risk from leaks
3 Jointing is quicker which means installation time is dramatically reduced
4 More and more plumbers are recognising that the benefits of plastic push-fit systems lie not in a direct price comparison of components, but in the speed of installation.
There is no risk of fire because no open flame is used during installation and no Hot Permit to work is required
5 Joints are easily demountable
6 All connections are made by hand – no tools are required
7 No tools means much easier to install in confined spaces
8 Plastic systems are quick to install, whether it’s a complex cabling system or a simple appliance connection
Most plastic push-fit systems can also be connected to copper pipework
FLEXIBLE PLUMBING | HIP BOOK 2015-16
Easier installation Recent research asked 1,059 experienced plumbers to estimate the time required to replace all the plumbing in an average bathroom with copper and then a second estimate using only plastic. The result is a 6 hour (28 per cent) time saving in favour of plastic. Therefore a normal 40 hour week for a bathroom installer using copper would reduce to 29 hours using plastic.
Plastic push-fit fittings are equally effective whether jointing plastic or copper pipe
Providing basic manufacturers rules are followed, plastic push-fit fittings are the easiest, quickest and most cost effective of all plumbing fittings to use.
The only tool required to make joints is a specialist cutter for plastic pipe or a pipe slice for copper pipe. A hacksaw should never be used as any burrs on the pipe ends may damage the O-ring inside the fitting. They are also just as easy to demount – while different manufacturers have different demounting methods, they all share a common simplicity.
With the appropriate pipe sleeve arrangement, plastic push-fit fittings can be used on copper or plastic pipe but not on chrome plated pipe as the chrome surface is too hard. To join chrome plated pipes, compression joints should be used.
New developments The most significant development in plastic push-fit technology in recent years is Hep2O’s ‘Next Generation’ range of fittings which was launched in November 2010 and features a number of new developments: The new fittings are slimmer in size and have a much sleeker and stylish design which means they now look a lot neater and less intrusive when placed in visible locations. Clearly, push-fit technology is continuing to move forward, largely driven by the same company that was so heavily involved in its original development back in the late 1970s.
1,059 plumbers estimated that an average bathroom would take 6 hours less to renovate if plastic fittings were used instead of copper

PLASTIC PUSH-FIT PLUMBING FOR PROFESSIONAL USERS Hep2O is the UK’s premier flexible push-fit plastic plumbing system for domestic hot and cold water supply, including potable water and central heating. The Hep2O system is designed solely for professional users and is currently the most widely specified system in use here in the UK.
The system comprises flexible plastic ‘straight coil’ polybutylene pipework connected to fittings that incorporate an integral push-fit
mechanism, making jointing quick and simple. Unlike other similar types of coiled plastic pipe, Hep2O pipe utilises ‘straight coil’ technology, which means the pipe does not return to its coiled state when uncoiled from the SmartPackTM dispensers. Instead, it remains straight but with no loss of flexibility, which makes it much easier to handle and ‘cable’ into position. The result is a lot fewer joints and a significantly faster, safer and more cost effective installation when compared to rigid plumbing pipe systems, such as copper.

HIP BOOK 2015-16 | HOT WATER CYLINDERS
AN INTRODUCTION TO DOMESTIC HOT WATER CYLINDERS Vented hot water cylinders have always been part of traditional gravity fed stored water systems, reliant on the size of the cold water tank in the loft for the amount of constant hot water that can be supplied. Unvented cylinder systems that are connected to the incoming cold main of a property can provide hot water at mains pressure. These high pressure systems are becoming an ever more popular, space saving domestic system to install, especially in properties with high levels of hot water demand, or where flow rate is an important consideration. The right type of cylinder must be specified according to the plumbing system to which it is connected. Therefore it is important to understand the differences between open vented, unvented, direct and indirect heating systems. Kingspan Environmental is a premier UK manufacturer of all types of hot water cylinder which work with most domestic hot water systems, including gravity primary and pumped solar models. There is an increasing demand for Solar cylinder (twin coil) installations, featuring a high efficiency, purpose-designed solar coil which allows maximum heat transfer of collected solar energy
into the stored water to satisfy the customers hot water requirements. However, this may be left unconnected to future proof the installation should renewable technologies be chosen at a later date (maybe because of future legislation). The second coil is suitable for connection to a gas / oil boiler. Finally, it is important to realise that extra components may be required to complete the installation. All Kingspan unvented cylinders are supplied with all the fittings and components needed for a complete package to create reliable, efficient and fast flow hot water delivery.
Most building work requires building regulations approval. For hot water cylinders, the relevant sections are Part G3 and Part L1 which stipulate requirements on water and energy efficiency for new and existing dwellings. Visit planningportal.go.uk/buildingregulations continued>>

OPEN VENTED HOT WATER SYSTEM The water in the cylinder is supplied from a storage tank known as the feed and expansion cistern (F&E cistern) filled from the mains and usually found in the loft or roof space. When a tap is opened, the hot water is forced out by gravity. The water in the cylinder is heated either ‘directly’ via an immersion heating element or ‘indirectly’ via a heat exchanger, in the form of a coil within the cylinder. As the water in the cylinder is heated it will expand and increase the system pressure. To prevent the build-up of pressure to dangerous levels, an expansion pipe is fitted to the hot water outlet connection on the cylinder. This expansion pipe must not be fitted with any means of isolation or restriction and must terminate above the level of the water in the F&E cistern. This Open Vent pipe gives this type of system its name.
UNVENTED HOT WATER SYSTEMS Unvented cylinders are connected directly to the mains water supply. When a tap is opened the hot water is forced out by mains pressure. The water in the cylinder is heated either ‘directly’ via an immersion heating element or ‘indirectly’ via a heat exchanger, usually in the form of a coil within the cylinder. An expansion vessel incorporating a flexible membrane is fitted with the cylinder connected to one side of the membrane. The other side of the membrane is charged with a gas at a set pressure. The water in the cylinder expands and cut-out thermostats ensure the isolation of heat sources if failures occur. A pressure reducing valve controls the incoming mains pressure, a non return valve prevents expanded heated water returning to the mains and an expansion relief valve will open if other components fail allowing the safe discharge of pressure from the cylinder. Every unvented cylinder is fitted with a temperature and pressure relief valve (T&P Valve) which will allow the safe discharge of water from the cylinder if temperatures or pressures exceed a set point. The system is sealed as there is no open vent pipe which is why it is called an unvented system. Temperature and pressure relief valve

SOLAR TECHNOLOGY
A twin coil solar cylinder must be used in conjunction with solar collectors such as Kingspan Thermomax vacuum tube collectors or FPW flat plate. The transfer fluid is heated via the collectors and passed through the lower coil of a cylinder to indirectly heat the water. Typically a second coil is present in the upper half of the cylinder which allows the water to be heated by a secondary heat source (Gas or Electric Boiler) for use when an additional energy source is required to meet the water demand. Cylinders are available with specially designed coils for use with heat pump systems such as the Abion Aerocyl Plus.

Copper cylinders traditionally have 2 ¼” BSP connections, and are sealed using a gasket. Stainless cylinders traditionally have 1 ¾” connections, and are sealed with an O-ring. Immersion elements are traditionally supplied up to 6 kW in single phase rating but can also be rated up to 9kW in three phase.

PROTECTING YOUR BUSINESS Working for yourself can be a rewarding experience, but ask any plumber who has been involved in a public liability claim and they’ll tell you that when it comes to protecting your business, having a good insurance policy is one thing you shouldn’t be without. Rules and regulations affect every business person from the sole trader to the multinational company, and from the small matters of maintaining the correct business bank accounts to VAT returns and contractual disputes. Part of this business administration maze is insurance. Hopefully, you’ll never need to claim, but what would happen if you didn’t have it, and just what business insurance should you have? In order to fully maximise your business potential it is essential to seek the correct training and advice on technical and professional matters. You will have completed, or be attending, a training course at College and therefore be up to date on the technical issues facing your chosen profession. But have you also received the same level of training on accountancy, legal and insurance matters? CORGI Insurance arranges insurance policies for thousands of plumbing & heating engineers within the UK Construction Industry.
The majority of our clients are sole traders or partnerships who require Public and Products Liability insurance for themselves as well as Public and Employers’ Liability insurance for trainees and temporary / casual sub-contractors.
In the UK, the only business insurance required by law (aside from motor insurance) is Employers’ Liability insurance - if you have employees - however there are other insurance covers that you really should consider. continued>>

Additional cover As well as core covers, you should look out for policies that allow you to add cover as you need it, such as Professional Indemnity insurance, which is designed to cover legal costs and expenses that might be incurred if you find yourself the subject of litigious action resulting from advice or guidance you have provided in your professional capacity. You should also look out for optional extensions such as Tools, Owned-Plant, Hired-In Plant and Contract Works. A good policy will allow you to select these as your business needs change.

CORGI Insurance arranges insurance policies for thousands of plumbing & heating engineers within the UK Construction Industry. is important. Almost every policy will have restrictions and exclusions on cover, and you should take the time to read and understand them. For example some policies will have restrictions and exclusions relating to the application of heat and / or fire precaution condition(s) that impose conditions when you use blow lamps, blow torches and ďŹ&#x201A;ame guns etc away from your premises. Some conditions are likely to be little more than common sense, such as ensuring that lighted blow lamps are not left unattended and you should have a suitable fire extinguisher available for immediate use. Other parts may require you to undertake a thorough fire safety check at regular intervals for a period of at least one hour after completion. These are examples only, and policies differ. Always be sure you understand the applicable conditions and restrictions.
Business Insurance is an important form of protection designed to provide peace of mind as well as protection in the event of an insured loss.
The premium you pay could be wasted if you have not fully read and understood the policy terms and conditions. It is not always the lowest premium that provides the best protection as it is the policy cover that is important rather than the initial outlay.
Before choosing insurance you should consult an insurance specialist who understands your trade and your working practices.

HIP BOOK 2015-16 | INSURANCE
CHOOSING THE INSURANCE THAT’S RIGHT FOR YOUR BUSINESS For many people, insurance is likely to be about their car, home or holiday. Once you’ve bought a policy, you may not need to change your cover very often. Buying business insurance is a little different, and there are more reasons why you might need to change your policy. What if your business grows, and you take on bigger jobs or start giving advice? What if you buy tools or plant, take on staff, develop an additional/ secondary trade, or employ bona fide sub-contractors? You won’t necessarily want a policy with cover you don’t need from the outset, and you need to know that you can add cover or increase limits as you need.
It’s not all about price Saving a few quid can be a false economy if you can’t claim when the time arises. Choose a reputable insurer that’s up front and honest, and look to see if they publish customer reviews – see what others think of them.
Range of cover Can you start with a core Public Liability policy, and then add cover such as Employers’ Liability, Professional Indemnity, Tools, Stock, Plant, Jury
Service and Personal Accident? You won’t want to have to change insurer to add cover.
Can you increase your limits? Even if you can get the cover you want, are the limits big enough for your growing business? Can you lower them if you need to?
Fees Take note of what fees are charged to change your policy. You won’t want to pay to update your policy just because you’ve moved. A good policy from a good insurer will grow with you, and won’t cost the earth or charge for un-necessary extras. CORGI Insurance has been insuring plumbing and heating engineers for many years, and we know that a flexible insurance policy can help protect your growing business. CORGI Insurance.

ALL YOU NEED TO KNOW ABOUT
MACERATOR PUMPING UNITS Bath in the basement, loo in the loft, shower under the stairs. All made possible by small-bore macerator pumping units. Thanks to small bore macerators it is possible to create extra bathroom, kitchen or utility facilities almost anywhere in a domestic property including ‘hard to plumb’ locations that would be impractical or expensive using conventional large-bore gravity drained discharge pipework.
showers, whilst other models, such as the new Sanifloor low level shower pump, will take waste water from the shower alone or the Sanivite that discharges grey water waste from kitchen sinks, dishwashers and washing machines. All the units pump waste horizontally and vertically through 22 / 32mm diameter pipework to existing drainage systems and provide an easy, quick and economic option for installing facilities where it would not be otherwise possible.
Benefits for the customer. Benefits for the installer.
Small-bore macerators can overcome limitations of traditional gravity fed drainage systems. The possibilities for new facilities in a domestic setting are endless. It’s even possible to create an ‘on trend’ wetroom space with the Sanifloor.
There is a huge range of macerators and pumps available to suit all types of plumbing needs. Some models will discharge waste from the whole bathroom including basins, WCs and
Today’s homeowners are increasingly adding value to their properties by converting spaces previously thought impossible due to drainage restrictions. But by selecting the correct Saniflo it is possible to convert under-stairs cupboards, lofts, basements, storage areas and garages into WC and washroom facilities. The clever, useful units also allow installers to spot opportunities for work even when access to mains drainage is remote. Once a plumber knows the capabilities of Saniflo pumps and macerators he (or she) can say yes to more jobs.

If a vertical lift is needed, this should be as close to the start of the run as is practically possible and from the highest point there must be a minimum 1% fall. The closer the vertical lift is to the machine, the more efficient the pump will be.
Bends should be smooth/long radius. This principle is true for all pipe sizes. Plastic

Pipes entering the Saniflo should have a gravity fall of 3%.
Where the pipework falls significantly below the unit e.g. a lower floor, fit an air admittance valve at the highest point capable of withstanding 10psi pressure, or increase pipe size coming down to ‘break’ syphon.
The unit should be easily accessible and removable in the event of maintenance being required. if boxed in, the boxing should be easily removed. Any extension between the WC pan spigot and wall should not exceed 200mm.

Since many closed coupled WC suites do not have the space between the WC pan spigot and the wall, you may have to batten the cistern off the wall to make room for the Saniflo. However Sanislim will fit behind most closed coupled WC suites without the need for this.
Position the Saniflo behind the toilet not beneath it.
Saniflo offer a complete range of pumps and macerators for all applications. Download our e-learning Module: www.saniflo.co.uk/e-learning.aspx
Electrical connection should be via an unswitched fixed wiring connector with a 5 amp fuse for Domestic range macerators. Professional range may vary – check individual instruction manual.
Macerators may only be used in a dwelling where there is access to a gravity discharging WC (Building Regs G4).

DEVELOP YOUR SKILLS With so many heating technologies on offer today and changes in legislation, it’s important to get ahead during your apprenticeship by attending additional manufacturer product training, explains Anna Wakefield, Marketing Manager for Grant UK. There’s a world of efficient heating methods for apprentices to discover. Here at Grant we not only supply an award winning range of condensing oil-fired boilers, but we also have a portfolio of renewable technologies like solar thermal water heating systems, condensing biomass boilers and air source heat pumps, as well as ancillary products such as cylinders, thermal stores and energy management controls. The Grant Training Academy offers comprehensive courses on all of these products, both on site in Devizes, Wiltshire and off-site at our partner centre in Hawes.
We see some outstanding apprentices pass through our Academy for both oil and renewable related products. One of the youngest women working in the oil industry, Tia Allen, recently took her OFTEC 101/ 105E/ 600A qualifications at the Academy in Devizes, Wiltshire.

Oil-fired boilers
Vortex Pro Combi XS
As Tia will know thanks to her training, modern oil-fired boilers are no longer the inefficient machines of the past. New condensing appliances can operate at almost half the cost of a typical 25 to 30 year old boiler, providing an instant return on investment and making it an easy decision for householders. The highly efficient Grant Vortex range features 46 different model variations with outputs from 12 to 70kW. Boilers available include internal and external, standard, system and combination versions, in wall hung and floor standing variants. Around 1 in every 2 oil-fired boilers installed in the UK is now a Grant Vortex (Source: SBGI). To complete the line-up, we launched the Vortex Pro Combi XS, the slimmest 26kW oil-fired condensing combi boiler on the market. At only 515mm wide, the XS is designed as a replacement for older inefficient standard efficiency oilfired combis, which tend to be smaller in physical size. To save on space, the 24 litre expansion vessel, normally located behind the front door of the boiler, is supplied as an ‘externally fitted vessel kit’.
The market for oil-fired boilers has been under pressure in recent years from other technologies and a lack of Government support for greener oil alternatives like bio-fuels. However, whilst in some cases renewable products are an option for off-gas users, there is no doubt that for the majority of homes, upgrading to a modern oil-fired condensing boiler from a standard efficiency model, is a good solution which would vastly reduce oil consumption and lower carbon emissions. Given that most installations are boiler replacements for older inefficient products and often are distress purchases, in our opinion the oil fired market is likely to remain strong for the foreseeable future, especially now the price of oil has hit a 5-year low.
The highly efficient Grant Vortex range features 46 different model variations with outputs from 12 to 70kW.

PIPE CLIPS & COVER SYSTEMS FOR THE 21 CENTURY ST
Across the country, building contractors working in the perennially busy RMI sector regularly pull up floorboards or tear down plasterwork to discover old pipe runs fixed to timber joists and studs using an assortment of bent nails and brutal looking metal bands. carries on, but the way the humble pipe clip has metamorphosed into something far more sophisticated and multifunctional is a reflection of just how much the building products industry has advanced since the post-WWII years. Currently, the heating industry and its specifiers are trying to come to terms with the new ErP directive and energy labelling of products or systems, but in respect of their long term effectiveness, choosing the correct clips and – where appropriate – cover systems is a crucial part of any installation. Sometimes the plumber or heating engineer – probably retired by now – will have wrapped the pipe in a bit of hessian to try and cut down the creaking and banging noises they make as they expand and contract. Like timber herring-bone struts and horsehair plaster, such anachronisms are gradually disappearing from our built infrastructure as the pace of refurbishment and redevelopment
Properly securing the pipework is essential to ensuring a safe working system, while it may also need to be enclosed for health & safety or aesthetic reasons.

HIP BOOK 2015-16 | PIPE CLIPS
For domestic installations there are generally three types of pipe clip available, Hinged clips, Open clips and Nail in clips. It is universally recognised that the most secure way to hold a pipe is via a hinged clip which ensures that the pipe has 360 degree support. When pipes are fitted to timber, typically in a roof space or under floorboards, nail in clips are usually the best option for speed and efficiency. Open clips are perceived by most professionals as a DIY option and although they offer a good snap tight fixing for the pipe, the clip does not have a closed top and therefore is not as secure as a hinged clip.
However, in recent years the move towards barrier pipe has introduced some new sizes, mainly 16mm and 20mm. In line with the introduction of new pipe sizes Talon developed a new range of ‘Flexi’ Pipe Clips which are now available to suit these sizes, but currently only in the hinged variety Also, for more robust environments such as public toilets and industrial premises, metal clips may be deemed necessary to resist vandalism or heavy usage: in which case there is a wide selection of copper, brass and chrome-plated clips available.
DID YOU KNOW? Hinged pipe clips are now available colour coded to easily identify pipes,
RED for hot water BLUE for cold and YELLOW for gas
pipe CLip spACeR Experienced tradesmen tend to be good at improvising, and where pipes are to be insulated it has been common to find a plumber has slipped an off-cut of copper pipe behind the clip as a ‘spacer’ for the screw fixing. It will allow room for pipe insulation to be fitted, but can look uneven and is a waste of copper, when a simple but effective Pipe Clip Spacer is available to slot into the base of a Hinged or Open Clip: raising it by precise 12 mm increments.
Traditional copper pipe sizes of 10, 15, 22, and 28mm have been around for many years. Plastic pipe manufacturers came into the market and followed copper sizes with the same dimensions when they were introduced in the 1990s - and therefore the existing pipe clips remained suitable for both copper and plastic pipe.
Pipe Cover Systems Exposed pipes are rarely attractive, while in situations such as schools or care homes they are considered a potential risk, requiring protection. Happily, however, a simple pipe

Where pipes are to be run beneath radiators, or around a room at skirting level, special brackets are available – including those with integral pipe clips – onto which the PVC-U profile is simply attached via a push fit tooth mechanism built into the profile. Where larger diameter pipe such as waste or soil and vent pipes have to be hidden Talon’s sister company Pendock offers a range of bigger profiles www.pendock.co.uk From relatively humble beginnings over a quarter of a century ago, Talon has grown to become the UK’s best known manufacturer of pipe clips, covers and related products. Talon Manufacturing not only managed to defy the downturn in the construction industry during the recession, but continued to invest in new product development and has emerged stronger since being purchased by Davidson Holdings.

Thanks to the products’ quality, ease of use and cost-effectiveness, Talon has become the Hoover of pipe clips; and continues to move forwards with an increasingly diverse range, under the leadership of Don Theobold.
DID YOU KNOW? All Talon products are distributed by the leading National Plumbers Merchants plus virtually all Independent merchants. They are also available through all leading catalogue based distributors.
The raw materials used to manufacture Talon products are always of the highest grade polypropylene or uPVC and the virgin grade materials used ensure that the quality is maintained and is consistent.
The future Continuing research and development enables Talon to react to changes in market demands, while at its premises in Gillingham, Kent, 24 state-of-the-art injection moulding machines run 24 hours a day to make sure that production keeps pace with demand at the company’s stockists. As a result Talon can therefore now offer a range of 14 hinged clips that covers 20 different pipe sizes from 10mm to 35mm.

THE VIDEO INSPECTION OF SMALL DRAIN LINES SERVICE RIGHT ON THE SPOT WITH THE VIDEO INSPECTION SYSTEM Even routine jobs may conceal unpredictable issues which extend work times for the plumber and pose an inconvenience for his customers. A blockage, for example, indicates a probable pipe breakage of which the full-blown effects become evident once the obstruction has been removed. The significance of such warning signs can be assessed with the aid of the video inspection camera system.
When is video inspection a good idea When re-laying the drains of a home, using this equipment on the pipes and storing the video recorded enable you to prove, in the event of a complaint, that the job was done properly. This is useful, especially when the drains are installed prior to other jobs during which paints or debris, caused by accidents or negligence might enter. After the video inspection job is done, a report can be sent to the customer. Inconvenience can be reduced even further by combining the camera with a locator. This locator will pinpoint the exact location where the pipe need repair, avoiding unnecessary additional construction works or even accidental damage to the piping.
The product The photographs illustrate the use of the RIDGID® SeeSnake® microDrain™ Inspection System, which is a portable pipe inspection diagnostic reel and camera with a 20m push
cable, combined with a hand-held RIDGID (www.RIDGID.com) micro CA-300 Digital Inspection Camera monitor of a 3.5 inch colour LCD screen. The product range includes different versions of reels, depending mainly on the push cable length and camera diameter. The pushrod inner drum is removable and interchangeable and is compatible with all other SeeSnake microReel or nanoReel models.
There is no risk of rust or accidental breaks as there are no weld lines. Drain lines from 32 to 100 millimetres can be easily inspected with the SeeSnake microDrain inspection system. The camera can pass multiple turns and 90-degree bends from 40 millimetres upwards with no need to dismantle them.
The RIDGID Navitrack Scout® locator is able to trace the pipeline and precisely detect the signal of a sondes (transmitter) to see where assessment or service is needed inside the pipe. The SeeSnake HQ software, which comes with the SeeSnake equipment and which can continued>>

Reports, which can include confidential remarks – not visible to the customer, can then be exported to a CD or USB memory stick. The 235MB internal memory can store over 2,000 photographs. Images and videos can be stored on the included 4GB SD card that comes with the micro CA-300 camera and transferred via the USB port to a computer.
Advice for the plumber “Before using the equipment, make sure the customer has not attempted to remove obstructions with hydrochloric acid. Any residues of this substance inside pipes might seriously damage the video inspection system. If hydrochloric acid has been used, remove the blockage with a pipe cleaning hose, run water through the pipe and then perform the video inspection: this procedure enables to check the obstruction’s causes and the condition of the pipes. Also make sure that the camera diameter is compatible with that of the pipe to be inspected. For example, if the minimum siphon diameter is 40 millimetres, the camera will be able to enter a pipe even of 32 millimetres, but it will get stuck from the first turn. To prevent damage to the drain lines and the equipment, first find out the minimum and maximum diameters and then use the appropriate reel. Also refer to the operator’s manual to comply with all the parameters described for a well done job.”

MOTOR YOUR WAY TO MORE POWER Simon Miller, Brand Manager for Hitachi Power Tools, looks at the latest battery and brushless motor technology available to apprentices. Buying your first set of power tools is an important decision. Your lecturer at college may influence you on which brand of power tools you use, but it is worth doing your own research and looking carefully at the different options and technology on offer. By selecting the right brushless motors and Li-ion batteries, you can increase run time and efficiency, saving yourself time and money. Cordless power tool technology is now providing tradespeople with greater performance, more run time per charge and longer warranties than ever before.
Getting in those hard to reach places can be tricky, and that’s when cordless power tool technology really comes into its own, especially if there is no on-site power source available for corded tools. There is nothing more frustrating than when the battery life does not last long enough or does not provide enough power to get the job done.
LI-ION BATTERIES Hitachi Power Tools was one of the first power tool manufacturers to have both 5.0Ah Lithium-Ion (Li-Ion) battery technology and brushless motors available on its 18V cordless range. This provides many advantages for users, including increased power, runtime and service life.

HIP BOOK 2015-16 | POWER TOOLS
Lithium-Ion battery technology is prevalent in the cordless power tool market because of its low memory effect and very slow loss of charge when not in use. In comparison cheaper battery packs often rely on a simpler “dump” charger with a less rigorous method of monitoring. This means they have to have a built-in margin of safety of up to 20% of charge, so can be less reliable, have shorter run times and could possibly be dangerous if misused.
The best Li-Ion battery packs, such as Hitachi’s, have telemetry to monitor temperature, discharge and heat of each individual battery cell, thus protecting the battery cells, the tool and the user more than ever before.
For instance, there’s the versatile and powerful CV18DBL 18V 5.0Ah LithiumIon Cordless Multi Tool, which features the efficient brushless motor designed to give outstanding and durable performance. The Multi Tool comes with a huge range of blades with which to get a multitude of tasks done. There are over 37 accessories available allowing users to edge, plunge and flush cut in wood, copper, tiles, plastics and nails.
Go brushless To increase performance, tool manufacturers are also turning their attention to developing extremely efficient electric motors. Brushed motors produce sparks, friction and heat, so the recent introduction of brushless motors by manufacturers such as Hitachi has seen an increase in efficiency, sometimes providing as much as twice the performance of a brushed motor. Hitachi’s brushless motor technology performs 150% more efficiently compared to conventional brushed motors.
Brushless motors improve dust proofing, which is important for installers as it gives the power tools a longer service life. This saves you time and money, not just in respect of cleaning your power tools, but replacing them too. The brushless motor can increase working time by up to 40% when used on those longer high-volume drilling jobs -but the brushless technology isn’t just confined to drills. Other accessories allow rough sanding, routing and caulk removal, all of which makes the CV18DBL 18V 5.0Ah LithiumIon Multi Tool a must have for every toolbag.
Flexibility Lithium-Ion technology and the introduction of brushless motors also provide tradesmen with more flexibility and choice in terms of which tool and battery pack they will use for the task in hand. For instance, a kitchen fitter who

This way they may only need to charge it once a week instead of daily. Larger capacity batteries combined with fewer charging cycles could also mean that the battery pack could last years before it reaches the end of its useful life. This enables quality power tool manufacturers to offer extended warranties on battery packs as well as the tools they power. Hitachi, for instance, offers

a three-year warranty once the tool has been registered online within four weeks of purchase. This covers not only the tool but any 4.0Ah and 5.0Ah Li-Ion batteries included.
Our 18V 5.0Ah cordless range includes combi, driver and SDS-Plus Hammer drills; circular, jigsaw and reciprocating saws; a planer, angle grinder, impact driver and wrenches; an automatic screwdriver and fan. There are also work lights and radios for use on site.
In conclusion, Lithium-ion batteries combined with the very latest brushless motors within cordless power tools offer apprentices flexibility and choice for the job in hand.

Getting social You don’t need us to tell you how important being online is these days. You can check your emails on top of a mountain with the latest 4G mobile data technology and you can upload your memoirs using the free Wi-Fi at your favourite fast food chain. Checking your Facebook feed or seeing what’s trending on Twitter has become second nature by now, but did you know that the savvy installer can use the net, and most importantly social media, to the advantage of their business too? The renewables plumbing and heating industry, like many others involves extensive networking. A lot of business is earned through
Twitter is a great way for installers to quickly respond to their customer’s queries. The biggest positive from signing up for Twitter is the goldmine of information that can be found on it – and fast. Pretty much every company or organisation that you’ll work with have a Twitter account. Following the right accounts gives you access to the latest news in the industry as fast as it comes out, whether it’s links to the latest government energy legislature or limited time offers on top products.
...the virtues of social media for small businesses cannot be overstated. word of mouth – installers often get work through recommendations from customers, colleagues and even merchants. This can all be very helpful and lucrative, but for some smaller companies, expanding their business beyond word of mouth can be tough, so the virtues of social media for small businesses cannot be overstated.
Think of a webpage for your CV – that’s LinkedIn. Users can add all of their work experience as well as connecting with people they have worked with, or for, in the past, as well as those that they’d like to in the future. It’s great for young installers starting out who are looking for a job at a renewables company, and most employers will expect you to have one now.
Smart business owners can create pages for their companies that customers can ‘Like’ and leave feedback on. Having good reviews from customers on a platform that reaches millions of people is never a bad thing, and it’s also a great place to post pictures of a job well done. Obviously on the opposite end of the scale are bad reviews, these are not be feared however. Installers can reply to the customer feedback publically or privately. It may be tempting to reply to a disgruntled customer in a private message, but sometimes openly talking to them about it in a constructive and humble way can really help a business owner come across as someone who really cares about their work and their customers.

THREAD SEALANTS YOUR GUIDE TO WHAT’S AVAILABLE
Non-curing and solvent-based sealing compounds, PTFE tape and hemp & paste are time-served methods of preventing leakage of gases and liquids from pipe joints. Increasingly, however, plumbers are turning to new technologies. Naturally, these products have been designed to make the job quicker but are they as effective? Let’s consider the pros and cons.
Traditional methods One of the oldest methods of sealing the spiral leak paths of threaded joints is with non-curing pipe pastes. Although they lubricate and compact into the threads creating a seal, they provide no locking. Furthermore they can squeeze out under pressure, have poor solvent resistance and do not work on parallel threads. Solvent-based sealing compounds also lubricate and compact into the threads creating a seal although fittings must be re-torqued to minimise the voids. Their greatest disadvantage, however, is that they shrink during cure as the solvents evaporate compromising the efficiency of the seal. PTFE tape gives a good initial seal and resists chemical attack. Although its ability to act as a lubricant is an advantage in one respect, this
action also prompts fittings to loosen under dynamic loads causing loss of clamping force and leakage. It also encourages over-tightening of fasteners, adding stress or fracturing parts. Its tendency to shred also makes it unsuitable for use in hydraulic systems as this can clog key apertures and lead to severe maintenance problems. Hemp and paste has been used for many years but it is messy and slow to assemble requiring a degree of experience and technique to achieve a complete seal. Another disadvantage of this sealing method is it cannot be used on fittings carrying potable water.
Emerging technologies ANAEROBIC ADHESIVES In recent years new technologies have been introduced that are designed to be simple and speedy to apply and also address the shortfalls of traditional methods. Top of this continued>>

list are anaerobic thread sealing compounds and sealing cord. These newcomers have some common advantages but essentially they are distinctly different technologies. Dealing with anaerobic thread sealing compounds first, they are single component products that rely on the absence of air and contact with metal to make them cure. They fill the space between the threads and provide an instant, low pressure seal.
A typical example is LOCTITE® 577. Suitable for bonding all coarse threads, this general purpose sealant has already been proven in the industrial market. It is a fast-cure product and provides a medium strength bond with excellent chemical and thermal resistance.
By comparison with traditional methods of sealing, anaerobic sealants are clean and easy to apply, can be used on the most popular sizes of pipe fittings and protect mated threaded areas against corrosion. Importantly, they also lock the fitting and resist vibrational loosening. These products don’t creep, shrink or block systems and any excess material can be simply wiped away.
Specific grades of anaerobic sealants are available for use with potable water, gas, LPG and heating oils. In practice, however, one grade of sealant could be used on the majority of domestic and industrial sealing applications where metal fittings are involved.
Anaerobic thread sealants are ideal for any type of metal fitting – typically iron, brass, copper and stainless steel. They seal regardless of assembly torque and to the burst rating of the pipe, providing controlled disassembly torque for subsequent maintenance. After cure, these sealants resist most industrial liquids and gases. They also have low toxicity and therefore specific products are often used in the food and beverage industry. Service temperatures are generally -55°C to +150°C but brief exposure to higher temperatures will not impair the seal. Continuous development of anaerobic adhesives has also led to the introduction of products that have no need to carry any hazard symbols, risk of safety phrases. They have been formulated to meet the growing demand for products that are kind to the user but don’t compromise the quality of the seal in the process.
SEALANTS | HIP BOOK 2015-16
SEALING CORD For many plumbers, a general purpose, threaded pipe and fitting sealant in the form of a cord – LOCTITE® 55 - has become a toolbox essential for sealing metal and plastic tapered threads. It’s easy to apply, clean to use and produces a highly reliable seal that meets all industry standards. There’s no need for special training to achieve an instant leak-proof joint. All the plumber has to do is wrap the sealing cord around the second, third and fourth male threads in a criss-cross action and assemble; instructions on the pack recommend the number of turns for the thread size. And another big benefit of the technology is that it allows fittings to be backed-off to achieve special alignments without fear of leakage. Cord seals against hot or cold water, gas and compressed air but is not suitable for oil fittings. For that application an anaerobic adhesive is the ideal choice and it’s a product that can also be used to seal olives to pipes and valve bodies, radiator valve faces and radiator tails with parallel threads.
135
Anaerobic thread sealants are ideal for any type of metal fitting – typically iron, brass, copper and stainless steel. SILICONE TECHNOLOGY Thread sealants, based on silicone, polymerise at room temperature by reacting with ambient moisture.
This product group is a good choice for threaded plastic or plastic-metal substrate combinations and, in common with sealing cord, allows post assembly adjustment; in an uncured condition.
This technology also includes latest generation sealing wraps. Developments in material technology now allow 300% elongation of the silicone wrap to achieve an extremely strong compression seal that protects damaged pipes against leakage and corrosion, even in temperature extremes. In summary, achieving a lasting seal is no longer a hit-or-miss process that is messy, time consuming and wasteful. The new breed of pipe sealants has turned a complex and temperamental task into one whose consistent quality is easily assured. For more details visit loctite.co.uk

LOCTITE PIPE SEALING PRODUCTS SIMPLE, EFFECTIVE & QUICK
For many plumbers, LOCTITE® 55 Pipe Sealing Cord is now a toolbox essential because it is so simple to use, produces a highly effective seal and saves time. By comparison with a hemp joint, a leak-free LOCTITE 55 seal is achieved in half the time and for less cost. It can also be backed off by up to 45° without fear of leakage. Simply wind onto the male threads in a criss-cross action; the thread size determines the number of turns. Cut the cord with the cutting device provided on the dispenser and press the loose end onto the thread. Screw on and fasten the joint with a pipe wrench and re-align if necessary. LOCTITE 55 is certified to DVGW standards, carries EN751-2 Class ARP for the gas industry and WRAS approval for use with potable water to 85°C. This product has been a top seller for Henkel for several years and on the strength of its effectiveness plumbers are now exploring what else is new in LOCTITE anaerobic technology. One product that is proving increasingly popular is LOCTITE 577, a general purpose sealant for all coarse threads. Time-served in the industrial market, LOCTITE
577 cures to provide a medium strength bond with excellent chemical and thermal resistance. It will not creep, shrink or block systems by shredding and is resistant to oil and coolants making it ideal for heating applications. In addition to oil fittings LOCTITE 577 is suitable for sealing olives to pipes and valve bodies, radiator valve faces and radiator tails with parallel threads. Another relative newcomer is LOCTITE 5075 insulating silicone wrap which can stretch up to 300%, effectively sealing and protecting damaged pipes against leakage and corrosion. It withstands harsh operating conditions and temperature extremes and is available in black and red. For further information visit loctite.co.uk

Finding solutions to the increasingly common problem of low mains water pressure is greatly simplified by Stuart Turner’s patented range of flomate mains boost pumps. Water pressure Although OFWAT stipulates that water companies must maintain a minimum pressure in the supply pipe of seven metres static head (0.7 bar pressure) at pavement level, most UK water authorities typically quote a standard of service which specifies that water pressure should not normally fall below ten metres head (1 bar pressure). A number of factors affect the actual pressure available at any given time. Pressure from your tap is largely dependent on the height of the tap above pavement level. Whether you share a service pipe with your neighbours, the time of day and the condition, size and length of your service
pipe will also influence the pressure available. The refurbishment of older three, four or even five storey high city properties can present very real problems for apartments on the higher floors. Another key factor is the amount of water being consumed in your area at peak times such as first thing in the morning and early evening. In some areas seasonal factors such as the use of water in tourist locations will have an effect. If you think that your water pressure is too low, the water supplier will investigate free of charge and provide advice on what you need to do.

However, even when the water pressure at pavement level meets the water supplier’s service agreement, problems may still be experienced on upper floors of the building.
Water flow Water flow is generally determined by the length and diameter of the supply pipe to your property. Problems with water flow can be caused by something as simple as a corroded stop tap that won’t open fully or, particularly in older developments where two or more properties share a single supply pipe.
Generally, if flow problems experienced relate to the size of the supply pipe it may be possible to install a storage cistern, a larger diameter pipe or a pipe dedicated to the property concerned.
Unfortunately in many situations the above solutions may prove to be impractical or extremely expensive.
The flomate pump uses an extremely reliable flow regulator to ensure flow does not exceed the 12 litre per minute UK water regulation limits.
Pumping water directly from the mains supply An alternative approach, and one which is finding increasing popularity with householders and installers alike is the installation of a water pump directly in line with the rising main. Many installers are uncertain as to whether a water supplier will permit the connection of a pump directly to the mains supply to a property. This belief is based on the fact that historically, pump products that complied with water regulations for direct mains connection were simply not available. This situation is no longer true. A WRAS approved pump drawing more than 12 litres per minute from the mains water supply may still be permitted in some situations, but the water supplier must be consulted beforehand.
SHOWER PUMPS | HIP BOOK 2015-16
A pump may be fitted directly to the incoming mains water supply, as long as it has been approved by WRAS – The Water Regulations Advisory Scheme (www.wras.co.uk) and has been designed to limit the water flow drawn from the mains to a maximum 12 litres per minute.
Flomate – for when your mains needs a boost WRAS approved products such as Stuart Turner’s patented flomate provide a simple and cost effective solution to boost low or intermittent mains water pressure without the need for a cold water break tank, making it ideal for properties where space is limited.
DID YOU KNOW? In fact, flomate will boost an incoming mains water pressure by an additional 1.5 bar at 12 litres per minute. The flomate pump uses an extremely reliable flow regulator to ensure flow does not exceed the 12 litre per minute UK water regulation limits. If, however the mains water pressure increases at times of low water demand and exceeds the minimum guaranteed by the water supplier, flomate’s patented bypass feature ensures that the resulting increase in water flow will bypass the flomate’s pump head and be supplied to the property without being restricted to 12 litres per minute, unlike alternative mains boost systems. Stuart Turner pumps are renowned for their superior quality and extraordinary reliability and longevity. In this respect, flomate is no different, featuring a machined brass pump and impeller coupled to a continuously rated high performance induction motor.
Boosting shower performance without a break tank Last year, Ricky Wilson of Central Emergency Services Ltd in Twickenham fitted a flomate pump and said “I was called out to a flat in Earls Court where the water pressure was really sporadic. The shower performance was not good at the best of times and if someone in an adjoining property turned on a tap, it really wasn’t worth getting into the shower at all!” “Installing a flomate made a dramatic difference to the shower performance. It was easy to install, located directly in line with the mains after the stop cock. The flomate pump has been installed and running for over a year now and is working perfectly, I haven’t had to make any return visits to the installation.” As with all Stuart Turner pumps, flomate offers tried and tested engineering designed and built to the highest standards of quality, innovation and reliability. Flomate is WRAS approved, operates in accordance UK water regulations and is supplied with a 2 year guarantee.

HIP BOOK 2015-16 | SHOWER PUMPS
WHEN EVEN FLOMATE ISN’T ENOUGH & YOU NEED EXTRA Although the boost to water pressure and flow created by the standard flomate unit may be suitable for smaller dwellings, in larger properties with higher occupancy the demand for water may exceed the 12 litre per minute limit supplied by the standard flomate solution. In direct response to this increasing trend, Stuart Turner has introduced flomate mains boost extra. This exciting new development combines all the features of the standard flomate pump and so can still be installed directly in line with the cold water mains supply pipe, but combines this with additional water storage provided by a 60 litre pressure vessel to supplement the increase in pressure and flow created by the pump. Stuart Turner’s flomate mains boost extra sits neatly within a standard 500mm kitchen base unit and is suitable for properties with more than one bathroom.
DID YOU KNOW? It will deliver up to 16 litres per minute water flow at up to 3 bar pressure to multiple outlets within a property for a defined period and will then continue to deliver 12 litres per minute until water demand ends and the pressure vessel recharges.
By supplementing the water pressure boosting performance of the flomate pump with the supply from the pressurised water cylinder, the patented ‘flomate mains boost extra’ offers the householder the ability to store water at pressure to meet peak demand.
It is easy to install, requiring no on-site commissioning and provides a fully assembled and tested solution to low water pressure problems.

A DIGITAL TOP 10 Roger Crabb, marketing manager of Mira showers, looks at how digital showers continue to provide the sector with growth opportunities â&#x20AC;&#x201C; and explains why not all digital showers are equal. Despite well publicised difficulties in the sector during the recession, one segment of the showers market continued to do rather well. Formerly the preserve of the up-market, digital products are now more widely available and at increasingly affordable prices. The technology is tried and trusted too â&#x20AC;&#x201C; digital long having been a mainstay of the commercial bathroom market, where precise temperature control and no-touch technology are essential features in healthcare and other settings. Hard numbers on the volume of digital products entering the market are hard to come by, not least because at least one manufacturer chooses to hide its light under a bushel and not share its data with either to the Building Services Research and Information Association (BSRIA) or BRG Consult. That said, we do know digital showers currently represent less than 5% volume share of the UK shower market; but the sector has seen considerable growth since the first launched in 2001. continued>>

Digital showers continue to outperform the recessionary market; and will – no doubt – start to pull away strongly when the economy cheers up again.
1
Is the digital control fully functional: by which one means, does it performs more functions than simply on or off? Ideally, the shower should be programmable to allow a number of functions to be set; including shower duration, maximum and minimum temperatures and flow rates, as well as a warm up mode and an eco mode.
2 That growth is anticipated to increase dramatically over the next few years as the technology becomes more accessible, prices reduce – and the ‘Smart Home’ concept increasingly takes hold. It is estimated that digital share of the market will double over the next five years, though that estimate could prove conservative. In the context of the Smart Home, the prospect of automation has been much vaunted over the past few decades, but has yet to make real inroads. However, a proliferation of new wireless and networkable devices is bringing the prospect of advanced control into the realms of the possible. Of course, like all technologies, some are more equal than others: remember Betamax, DAT or MiniDisc? Of course not! It’s the same in the digital showering arena – there are digital showers and there are, as you might say, digital showers. Some are bang-up-to-date, while others haven’t quite moved on in the same way since the early days of the concept. Consequently, what are the features (and their benefits) you should look for in a digital shower to ensure that you, and your customer, are getting today’s technology and not a Betamax job.
FULLY FUNCTIONAL WIRELESS CONTROL
FULLY FUNCTIONAL SECONDARY WIRED CONTROL
As above: if not using the shower wirelessly, does its wired control provide for more flexibility than simply on or off?
3
DIGITAL DISPLAY
As incredible as it may seem, there are digital showers out there that don’t, er, display digitally. Apart from the seeming contradiction – why would you want a digital watch with hands? – it makes it difficult for the user to appreciate what settings have been programmed; and which ones are operational at the time of use.
4
CLOCK DISPLAY
Going back to the watch analogy: one might as well have a clock if there’s going to be a digital display. And, actually, it’s surprising how many time-poor consumers concern themselves with shower duration – either programmed in, or by keeping a weather eye on the clock.
SHOWERS | HIP BOOK 2015-16
5
WARM UP MODE
Does what is says on the tin really. This function allows the user to operate the shower for a short period in anticipation – improving the experience and avoiding any early bursts of ‘dead leg’ cold water.
6
ADJUSTABLE FLOW CONTROL
Single lever operated showers definitely have their place, but when one is presented with the operational opportunities provided by digital, it’s obvious that temperature and flow controls can be easily separated. Which, obviously, gives the user greater convenience and flexibility in choosing the shower that’s ‘right’ for them.
7
8
ADJUSTABLE LOCATION FOR UI
The beauty of digital is that the user interface needn’t actually be adjacent to the actual shower at all. The siting possibilities are many, and means that the main UI – or controller – can be located to the consumer’s convenience – or even ported like a remote control.
9
10 UP, DOWN, HIGH LOW And a choice of supply and pressure installation options is always very handy: be it either ceiling or rear fed fitting and with a choice of high pressure valves for mains pressurised systems or combination boilers or pumped valves for low pressure or gravity fed systems. Not to mention the flexibility to site the valve somewhere discrete; be it in the loft, under a bath or other convenient location up to 10 metres from the controller.
MAXIMUM TEMPERATURE ADJUSTMENT ON USER INTERFACE (UI)
As implied above in the comment regarding fully functional wireless or wired controls; it is convenient for the user – within safe bounds – to be able to set their own maximum temperature limits. Where such an opportunity doesn’t exist then, of course, they have to have one set in advance by their installer in the valve assembly; and future adjustment is going to be a pain.
EXTRA REMOTE CONTROLLERS
And where the UI is fixed to a wall? Your customer’s family is like our family and your family. It helps to have more than one controller knocking around...
147
Digital showers continue to outperform the recessionary market; and will – no doubt – start to pull away strongly when the economy cheers up again. As the technology becomes more accessible, prices reduce – and the ‘Smart Home’ concept increasingly takes hold; consumers will be lining up to enjoy the same breadth of digital functionality that they enjoy from other appliances. Of course, any forward thinking installer will be there to exploit that – if not doing so already – but it pays to know what you’re offering: Betamax, VHS or, instead, Blu-ray!

INNOVATION & QUALITY KEEPS MIRA AHEAD People do not continue to improve as they get ever older particularly as they pass their 94th anniversary but companies can, as Mira – Britain’s biggest and longest established shower manufacturer – demonstrates. The Cheltenham-based firm, revealed by research as the one most trusted by UK installers, is at the forefront of showering technology with a range of sophisticated products that incorporate a raft of innovations, from digital showers to remote controls. In 1921, when James M Walker and Walter W Crossweller founded the original firm, the company distributed German industrial instruments as well as American water and oil meters. The move into valves came when it was appointed the UK distributor and licensed manufacturer of Leonard thermostatic range in 1936. Later It developed the Leonard 722, the first thermostatic shower valve to cope with the UK’s unique pressure conditions, and the Mira 8 manual mixer. And the Mira 8, launched in 1963, swiftly became the best-selling brand on the market, selling its millionth unit in 1984 in a production run that lasted well over 20 years. And the innovations just kept coming – the then revolutionary thermoscopic mixing valves launched in 1979, the Mira Supreme electric shower with patented flow regulator and the Mira Electronic Bathroom control system – a world first in integrated electronic controls for all bathroom functions. The company launched the world’s first thermostatic electric shower, the Mira Advance, in 1995 with 8.7kW and 9.8kW versions and 5 memory variants.
Having launched its first ever digital shower in 2005, the latest offer is Platinum Dual which offers users both a deluge head and a handset that can be used together or independently. Further luxury is also possible for consumers combining their shower and bath tub with the bath fill function which eliminates the need for taps, creating a clean minimalist look. And Mira wireless technology has been extended to the Mira’s Advance Flex Extra Wireless, which offers wireless pairing to a waste water pump. This simplifies installing or retro-fitting a wet room in situations where a conventional gravity fed drainage system would not be feasible.
Whatever the application, and whatever shower type you opt for – you can always trust Mira for innovation and engineering quality. For more info visit mirashowers.co.uk

HIP BOOK 2015-16 | UNDERFLOOR HEATING
UNDERFLOOR HEATING Energy-efficient comfort Underfloor Heating (UFH) using piped warm water is a modern and energyefficient option for heating homes and other buildings. UFH also delivers comfortable warmth for occupants, as well as other practical benefits.
Heating principles With UFH, the floor is gently heated by piped warm water (or alternatively by electric cable) and the heating energy is emitted from the floor by natural radiation. This heat is absorbed by other surfaces in the room which then also emit warmth. The result is an all-round, more even warmth than is typically achieved by other space heating techniques. Radiators, for example, use room air to transfer the heat, mostly by convection. This reliance on the convection of air to heat the room results in uneven warmth and higher temperatures at ceiling height compared with floor level. 20°

As radiators intrude on the usable space within a room, there is a general desire to keep them as compact as possible. As a consequence of this, the piped water has to be hotter than for UFH in order to achieve the same level of comfort for the occupants.
20° 20°
26°- 28°
Plumbed UFH uses piped warmed water from any primary heat source. This may be from a conventional domestic boiler that is also supplying domestic hot water. In some situations, the boiler may be supplying heated water for radiators as well as for UFH. Alternative sources of warmed water may be heat pumps or solar water heating. UFH is especially suited for such renewable heat sources because it requires water at lower temperatures than traditional heating techniques. continued>>
152
HIP BOOK 2015-16 | UNDERFLOOR HEATING
PRINCIPAL ADVANTAGES OF UFH Underfloor heating offers many benefits to the homeowner. Lower water temperatures required for UFH mean better energy efficiency with fuel bills up to 20% lower More even room temperature ensures all round comfortable warmth Silent running – no expansion creaking or water flow noise Unhindered room layout - because there are no wall-mounted radiators Healthier environment - because less dust is circulating in the air Decreased irritants - as the warm floor inhibits the breeding of dust mites and fungi Greater safety - because there are no exposed hot surfaces Low maintenance - no radiators to redecorate or renew, or to be ‘dropped’ to allow room redecoration
The Three Essential Elements Plumbed UFH comprise of three key elements that work together to deliver the required heating performance and effect: 1. Floor products incorporating UFH pipe: to create the pipework circuits within the floor that will emit heat. Many floor products help to hold the pipe at the correct spacing to ensure even distribution of heat across the floor surface above. 2. Manifold: to provide flow and return circulation of warm water at the correct temperature and flow rate to ensure an even, comfortable temperature across the whole floor surface.
3. Controls: to monitor water and air temperature and signal the heat source. In effect, the nerve centre of the installed system. The careful selection of each of these is critical to the efficient operational performance of the entire installation. Let’s look at these in more detail;
1
FLOOR pRODUCts
The choice of floor product is influenced by several factors: Whether the floor is being newly constructed or already exists Its type of construction: solid / screeded or dry / timber The size and shape of the space to be heated The type of floor finish that will be installed over the UFH A solution to suit any combination of these factors, can be found within the Hep2O underfloor heating product range.
2
mAniFOLDs
A manifold is required wherever UFH is to be installed to serve two or more plumbed circuits from the same primary heat source. When UFH is being connected to a high temperature heat source which also controls hot water or other heat emitters, a mixing unit is connected to the manifold to mix the water to the required temperature for the system.
UNDERFLOOR HEATING | HIP BOOK 2015-16
The Hep2O underfloor heating range includes manifold solutions that can be tailored to each situation. The composite Manifold can be sized to serve the exact number of individual UFH circuits up to a maximum of 15 circuits. Single circuit installations which require water temperature control will be connected to their heat source via a mixing unit, but will not require a full manifold.
3
COntROLs
As with any type of heating, UFH operation requires time and temperature control. The choice of controls will initially be based on these key factors: Whether wired or wireless installation is practical or preferred Requirement for programmed or non-programmed operation Number of individual circuits – and whether these are to be controlled separately or linked In addition, special operational features and functions may be included to enhance convenience (e.g. remote operation) or operational safeguards for householders (e.g. frost settings, child / interface lock). Many controls are now web enabled and can be controlled by Apps. Hep2O underfloor heating controls provide a comprehensive choice for solutions tailored to the specific needs of each installation – and the preferences of the householders.
Floor finishes All UFH installations are overlaid with a final floor finish. This may be: carpet; resilient vinyl; linoleum (or equivalent); stone; ceramics; timber or laminate. As with different types of floor construction, the thermal resistance of each floor finish option varies. This can affect heat output. Allowance should be made for the thermal resistance of the floor finish, in combination with
153
that of the floor construction, to ensure this will not prevent efficient heating performance.
Typical layouts When laying out the pipe there are several patterns that can be used. This will depend on the size and shape of the room and installer preference. TYPICAL PIPE LAYOUT PATTERNS There are two typical patterns for laying UFH pipe: Spiral – this follows room shape in a spiral to the middle and is then reversed out. This pattern is possible with two Hep2O underfloor heating systems – Staples and System Plates. SPIRAL LAYOUT
SERPENTINE LAYOUT
Serpentine - pipe is laid in parallel runs up and down room length, with loop turns at each end. For systems that use pre-drilled channels e.g. Hep2O low build system, this is the pattern which is used.
Advice, tools and guidance Most manufacturers will offer advice and online tools to help you select the correct system, calculate the heat losses determine what product required for the job, and give advice on installation. Hep2O have an online calculator which will help you work out what you need for a specific project and give you a list of materials you can take in to your merchant. They also have a range of product and installation guides with detailed guidance on each system. These can all be found at wavin.co.uk

INFORMATION & TECHNICAL ADVICE Now you’ve completed your training and put away your text books, you’ll never need to get them out again, right? Well, maybe…. but remember that as the installer, you’re the one who has to ensure that your work complies with the Water Fittings Regulations. And if your work doesn’t comply, you risk prosecution for a criminal offence and the water supplier can require alterations, at your own cost, to make your work comply. So - because no-one knows everything - sooner or later you’ll have questions about some part of the Water Fittings Regulations. Where can you look for answers?
WRAS One place to try is the new website of the Water Regulations Advisory Scheme WRAS (www.wras.co.uk). This has advice and guidance on topics ranging from the legal requirements for installing and maintaining reduced pressure zone (RPZ) valves (type BA devices), designing air gaps for cold water storage cisterns, installation of rainwater harvesting and reclaimed water systems, and accessibility of water fittings in walls and under floors.
There are leaflets about commissioning plumbing systems and about fluxes and where you mustn’t use lead solders.
WATER REGULATIONS | HIP BOOK 2015-16
And although you may know about the regulations, your customers might find useful the leaflets on what the regulations are about and how to give proper notification of planned work to the water supplier. There’s a series of customer-friendly booklets which describe how the regulations apply to different types of premises, such as farms, caravan sites and sports grounds, with more titles being added from time to time.
Guidance on regulations Maybe even more useful is the website section which gives recent water industry interpretations of the regulations. You may have a copy of the Water Regulations Guide, but there have been further interpretations of the Regulations which aren’t printed in the Guide. These are in the ‘Interpretations & Advice’ section of the website.
DID YOU KNOW? Water can be dangerous, no-one wants their drinking water to be unsafe. Backflow prevention is one of the most important aspects of the Water Regulations, and in addition to point of use protection, zone and whole site protection may be required.
157
Advice And if you can’t find the answer from all that, WRAS offers a technical advice service. You can ring up, or send a letter or email asking any technical question about the regulations and WRAS will do its best to answer you. And the best thing is – it’s all free.
DIRECTORY Finally – to be sure the water fittings and appliances you are about to install will comply with the regulations (in line with your legal obligation!) you can check if they are listed in the WRAS Water Fittings and Materials Directory. The Directory has thousands of fittings and appliances which have been assessed for their compliance and have been approved on behalf of the water suppliers. If it’s listed in the Directory and installed in accordance with any installation requirements, it should comply with the regulations. The Directory is FREE on the internet (www.wras.co.uk/Directory) and is updated monthly. The Water Regulations Advisory Scheme (WRAS) is funded by the UK water suppliers to publicise and to promote consistent interpretation of the Water Fittings Regulations in England, Wales and Northern Ireland and the Scottish Byelaws hereafter referred to as the regulations

IT’S DOWN TO YOU! You might think no-one would sell a plumbing fitting which was illegal to install…but sadly, you’d be wrong. DID YOU KNOW? Under the Water Supply (Water Fittings) Regulations, it’s not illegal to sell you a fitting which doesn’t comply, but you could commit an offence by installing it. It’s the Installers’ legal duty to ensure that water fittings they install meet the requirements of the Regulations.
Using approved products ensures rapid acceptance by the water company’s inspector and will reassure users that their plumbing is correct, robust and reliable. When you’re buying or installing products look for the logo.
Testing
Approved products So how on earth can you tell if the product is OK? One reliable method of demonstrating this is to use WRAS Approved products. These have been assessed and approved by the Water Suppliers who enforce the Regulations, so if it’s got their OK, and you install it in accordance with any conditions which are written down, your work will be fine.
Every product is extensively tested to performance requirements which are laid down by Government. Taps are operated 200,000 times to check they’re leak-tight over their full life. Pipes are pressure tested with hot water as well as cold if they’re for heating systems. Air gaps are measured for backflow protection and materials in contact with water are tested for absence of nasty tastes or toxic substances. When it comes to toilets, in addition to wash-down tests, flush rate tests and endurance tests, they’re tested with artificial poo to see if it clears the pan correctly! And of course, check valves are checked. You can find WRAS Approved products in the WRAS Water Fittings and Materials Directory FREE OF CHARGE on the WRAS website at wras.co.uk/Directory

BECOME A WATERSAFE APPROVED PLUMBING BUSINESS Why Be A ‘WaterSafe Approved’ Plumbing Business? Some unqualified installers pretend to be competent but do a poor job. Being a ‘WaterSafe Approved Plumbing Business’ reassures customers that you’re not a cowboy. Approved contractors can also carry out some installation work without waiting for the Water Supplier’s consent, saving time, reducing paperwork and avoiding delay. Usually, Water suppliers don’t require inspection of Approved Plumbers’ work, speeding up the supply turn-on. Customers value the certificate you give them as an Approved Plumbing Business stating your work complies with the Water Supply (Water Fittings) Regulations and Scottish Water Byelaws.
Approved contractors’ schemes To become ‘WaterSafe Approved’ you need to join one of the existing Approved Contractors’ Schemes.
WHO RUNS APPROVED CONTRACTORS’ SCHEMES? There are seven Approved Contractors’ schemes, run by:
The Association of Plumbing & Heating Contractors (APHC)
The Chartered Institute of Plumbing & Heating Engineering (CIPHE)
The Scottish & Northern Ireland Plumbing Employers’ Federation (SNIPEF)
Water Suppliers - Anglian Water, Severn Trent Water or Thames Water in their respective areas and by the Water Industry Approved Plumbers’ Scheme (WIAPS) for the remaining water suppliers’ areas. In England and Wales you can join the scheme in your water supplier’s area. There’s flexibility, so water suppliers accept each others’ certificates if you work across supply boundaries. ‘WaterSafe Approved’ Plumbing Businesses are recommended to customers by their water supplier. You can get extra business - some organisations will only use Approved Plumbing Businesses.
WATER REGULATIONS | HIP BOOK 2015-16

Customers value the certificate you give them as an Approved Plumbing Business... What is watersafe? Introduced in 2013, ‘WaterSafe’ is an umbrella organisation bringing together the seven existing Approved Contractors’ Schemes under a nationally recognisable brand which can be promoted to customers across the UK. It provides a customer-friendly website listing Approved Businesses which are members of the Approved Contractors’ Schemes and each ‘WaterSafe’ recognised individual within them. Water suppliers are promoting the use of ‘WaterSafe Approved’ Plumbing Businesses to their customers through newsletters, billing information and leaflets.
The Water Industry Approved Plumbers’ Scheme (WIAPS) Membership of WIAPS is free. To join, you need a plumbing qualification (NVQ Level 2 or equivalent as a minimum), a Water Fittings Regulations Certificate along with public liability insurance and employers’ liability cover where appropriate. On joining, you get free packs of ‘Work Completed’ certificates and regular technical updates. Members can use the WIAPS and WaterSafe logos on their letterheads and get free vehicle stickers.

WATER REGULATIONS GUIDE INFORMATION ON NOTIFICATION OF PROPOSED PLUMBING WORK The following information is an extract taken from the Water Regulations Guide. What are the Water Fittings Regulations? The Water Fittings Regulations, or Byelaws in Scotland, hereafter referred to as regulations, are national requirements for the design, installation and maintenance of plumbing systems, water fittings and water-using appliances. Their purpose is to prevent misuse, waste, undue consumption or erroneous measurement of water and, most importantly, to prevent contamination of drinking water.
WHERE DO THEY APPLY? All plumbing systems, water fittings and water-using equipment in all types of premises supplied or to be supplied from the public water supply come under the regulations. The regulations apply from the point where the water enters the property’s underground supply pipe. Premises without a public water supply connection are not governed by these regulations.
Who has to comply with the Regulations?
Owners and occupiers of premises and anyone who installs plumbing systems or water fittings have the legal duty to ensure that the systems satisfy the regulations. Architects, building developers and plumbers have to follow the regulations on behalf of future owners or occupiers. Advanced notice must be given of most proposed installations to obtain consent for the work from your water supplier. It is a criminal offence to breach the regulations and offenders may face prosecution.

Plumbing systems must be designed, installed and maintained to meet the requirements of the regulations and their Schedules. This is to protect water quality, to ensure safety, ease of access for maintenance, detection of leakage, protection against damage or freezing etc.
At present they must either conform to an appropriate British Standard or some other European Economic Agreement state specification which provides an equivalent level of protection and performance or conform to a specification approved by the Regulators. The Water Fittings and Materials Directory, published by the Water Regulations Advisory Scheme (WRAS), gives up-to-date details of a wide range of items which satisfy the Regulators Specification.
If you are carrying out your own installation work ensure you know what requirements you must meet. If you are employing someone else, consider using an Approved Plumber who will certify compliance of the new installation.
Whilst it is not illegal to sell unsuitable fittings and appliances, to install one would be illegal, so check suitability before purchase. The Directory is free to access on the WRAS website: wras.co.uk/directory.
Advanced Notification Prevention of contamination by backflow Backflow occurs when contaminated water flows in the opposite to intended or normal direction of flow. Where water or water-using equipment is used with fluids or materials which could contaminate the water, there must be adequate protection to stop backflow of potentially contaminated water into other parts of the system, especially drinking water outlets. The regulations define Fluid Risk Categories according to the contaminants which are present and specify the appropriate type of devices or arrangement which must be fitted to protect against backflow.
Choice of materials & fittings Plumbing materials and fittings must meet the standards given in the regulations.
In most cases, before work starts on any proposed installation, the installer, owner or occupier must obtain the water supplier’s consent by giving notification of the details of the proposed work. Proposed work which must be notified is summarised in the following list.
The installation of a water fitting in connection with: 1. The erection of a building or other structure, not being a pond or swimming pool 2. The extension or alteration of a water system on any premises other than a house (#) 3. A material change of use of any premises 4. The installation of: a. a bath having a capacity, as measured to the centre line of the overflow, of more than 230 litres (*) b. a bidet with an ascending spray or flexible hose (#) continued>>

c. a shower unit of a type specified by the Regulator (none are currently specified) (*) d. a pump or booster drawing more than 12 litres per minute, connected directly or indirectly to a supply pipe e. a unit which incorporates reverse osmosis f. a water treatment unit which produces a wastewater discharge or which requires the use of water for regeneration or cleaning
g. a reduced pressure zone (RPZ) valve assembly or other mechanical device for protection against a ďŹ&#x201A;uid which is in Fluid Category 4 or 5 h. a garden watering system unless designed to be operated by hand (*) i. any water system laid outside a building either less than 750mm or more than 1350mm below ground level 5. The construction of a pond or swimming pool over 10,000 litres capacity, designed to be replenished automatically with water supplied by a public water supplier. (*)
WATER REGULATIONS | HIP BOOK 2015-16
In Northern Ireland and Scotland, in addition to the above, notification is required for: grey water, recycled water, reclaimed water and rainwater harvesting systems water systems for firefighting, including domestic sprinklers a flexible shower hose or other flexible outlet for use in conjunction with a WC (#) a ‘shower toilet’ or ‘bidet-toilet’ where either as part of the WC itself or as an addition or adaptation of it, a stream of water is provided from below the spillover level of the WC pan for personal cleansing (#). In Scotland, there is an additional requirement for notification of any system incorporating a private water supply.
DETAILS TO BE NOTIFIED For installations to be supplied with water from the public water supply, the following information must be sent to your local water supplier:
165
Granting consent There is no charge by your water supplier for dealing with notifications or granting consent. Work on installations must not start until consent has been given. If consent is neither granted nor refused within ten days of the water supplier receiving a valid notification, consent is deemed to have been granted. This does not alter the obligation upon the installer and owner or occupier to see that the Regulations are fully met.
APPROVED CONTRACTORS An approved contractor, often called an approved plumber, will certify that their installation work satisfies the Regulations. In the event that this certified work contravenes the Regulations, the owner or occupier can use the certificate as a legal defence against prosecution.
The name and address of the person giving notice and, if different, the name and address of the person to whom the consent should be sent. A description of the proposed work or any significant change of use of premises. The location of the premises and their use or intended use. Except for items marked (*) in the list overleaf, a plan of those parts of the premises which relate to the proposed work and a diagram showing the pipework and fittings to be installed. The plumbing contractor’s name and address, if an Approved Plumber is to do the work.

HIP BOOK 2015-16 | WATER REGULATIONS
There is no charge by your water supplier for dealing with notifications or granting consent. An approved contractor, when installing items marked (#) in the list adjacent, does not have to receive prior consent before starting work, but on completion in addition to supplying a certificate to the person who asked for the work to be done, a copy of the compliance certificate must also be sent to the water supplier.
Most UK water suppliers either operate their own approved contractor scheme or support the national Water Industry Approved Plumbers Scheme (WIAPS), whose members have demonstrated their experience of plumbing work plus knowledge of the Regulations and have liability insurance cover.
Notification through Approved Contractors’ Schemes WaterSafe is an online national register and search facility that enables customers to locate an approved contractor in their area. As well as the four approved plumber schemes operated by water suppliers, the Chartered Institute of Plumbing and Heating Engineering (CIPHE), the Scottish and Northern Ireland Plumbing Employers Federation (SNIPEF) and the Association of Plumbing and Heating Contractors (APHC) also list approved plumbers (see right for contact details).

DEAD LEGS, SERVICING VALVES & REGULATION INTERPRETATIONS The following information is an extract taken from the Water Regulations Guide with additional helpful advice. possible and capped off, ideally no longer than twice the length of the pipe diameter. See the interpretation on the next page for full details.
If you are installing branch pipes to facilitate future connections, don’t connect them until they are ready to be used. Install the pipework but seal both ends to prevent anything getting inside. Once the pipework is ready to be used, cut your tee piece in and connect the pipework, remembering to thoroughly flush it before making the final connection.
REDUNDANT FITTINGS & DEAD LEG g11.7 Any draw-off fitting that is permanently removed from the installation should have the branch pipe serving the fitting disconnected at its source. By leaving redundant pipework connected to the plumbing system you increase the risk of contaminating the water. Stagnant water may promote the growth of bugs, especially where it is in a warm area. Any redundant pipework should be completely disconnected and removed from the system, ideally removing the tee piece. There may be occasions where it is just impossible to remove a tee piece, in this instance the redundant pipe should be cut as short as
If you disconnect an appliance that requires repair, there is no need to disconnect the branch pipe. Just make sure the appliance is repaired or replaced and reconnected within 60 days. Again, just remember to flush the pipework before you reconnect.
PROVISION OF SERVICING VALVES g11.1 Inlets to all float-operated valves, cisterns, clothes washing machines, dishwashing machines, water heaters, water softeners and other similar appliances should be provided with a servicing valve to facilitate maintenance. continued>>

HIP BOOK 2015-16 | WATER REGULATIONS
g11.2 Servicing valves should be fitted as close as is reasonably practical to float operated valves or other inlet devices of an appliance.
To facilitate compliance with, and support consistency in the application of these Regulations, water suppliers, assisted by WRAS, have produced a number of technical interpretations and other advice.
g11.3
INTERPRETATION N05
Servicing valves may be of the screwdown or spherical type. Servicing valves should be installed adjacent to the appliance they are serving, and in readily accessible locations. Usually servicing valves are the screwdriver operated type, but screw down stop valves would be perfectly acceptable. You can even use hose union bib taps for isolating appliances such as washing machines and dishwashers! See the interpretations on the next page for more information. There is no requirement to fit servicing valves to taps, but it is certainly good practice to do so. It makes life easier should you need to replace a tap at a later date, and less water will be wasted as you won’t have to drain the whole system.
Area of Interest: Notification Topic: Material change of use Title: Notification of changes relating to storage and use of fluid category 4 or 5 substances Clause Reference: Regulation 1& 2 Reference Number: N05 Decision Date: June 2015 It is a requirement to notify any proposed plumbing work relating to a material change of use. This includes any changes to a plumbing system for the storage and / or use of substances which if mixed with water would be classified as either fluid category 4 or 5, for example the installation of a rainwater harvesting or grey water system in any premises.
INTERPRETATION I21 INTERPRETATIONS & ADVICE Water suppliers have a legal duty to ensure that the Water Supply (Water Fittings) Regulations and Scottish Water Byelaws are complied with in their appointed area of supply.
Area of Interest: Installation Topic: Dead leg Title: Dead legs Clause Reference: Regulation 3 (2) (i) Reference Number: I21 Decision Date: September 2008 Where water is allowed to stagnate there is a risk of contamination. Minimising this risk can be achieved by: Completely removing redundant pipe work. Where this is not practicable the pipe should be terminated so that any ‘dead leg’ so created is no longer than twice the diameter of the pipe. This general principle should also be applied to fittings which by design incorporate areas which do not have a steady through flow of water.
WATER REGULATIONS | HIP BOOK 2015-16
For pipework supplying fittings which are used infrequently i.e. fire supplies or water reuse systems with a back-up supply, appropriate backflow protection should be installed as close as reasonably practicable to the mains or supply / distributing pipe.
169
INTERPRETATION B34 Area of Interest: Backflow prevention Topic: Fluid category Title: High risk tap installations Clause Reference: Schedule 2 paragraph 15 & G15.3 Reference Number: B34 Decision Date: May 2005 (revised June 2015) Taps used in high risk installations, such as kitchen sinks, are considered to be a fluid category 5 risk. Backflow protection is usually provided in the form of an AUK3 tap gap. Where an AUK3 tap gap cannot be maintained, for example where the tap gap is compromised as a result of:-
the tap being lowered in any way; adjustment to the spout which reduces the
INTERPRETATION B54
distance between the tap outlet and spillover level of the sink; or the operation of a pull out hose attachment
alternative fluid category 5 backflow protection is required.
Area of Interest: Backflow prevention Topic: Temporary filling loops Title: Disconnection of temporary filling loops Clause Reference: Schedule 2 paragraph 24 & G 24.2 (a) Reference Number: B54 Decision Date: June 2012 When not in use it would be preferable for temporary filling loops to be completely disconnected and totally removed, however a partial disconnection, that is to say only detaching one end of the filling loop, will be permitted providing that the disconnection is made between the filing loop and the backflow prevention device on the supply pipe. (Also see B09 ‘Temporary arrangements for rapid filling of heating and cooling systems in non-domestic premises’ & B22 ‘Filling and topping up heating system primary circuits’)

TRUST ME, I’M A PROFESSIONAL INSTALLER Recent research shows that energy costs remain the biggest concern for UK households. Homeowners are more worried about affording energy bills than paying the rent or the mortgage. According to the Energy Saving Trust, household boilers account for around 55% of what we spend in a year on energy bills. That’s why taking care to ensure it’s working as efficiently as possible is one of the easiest ways every home can save. John Vaughan, Managing Director at ADEY Professional Heating Solutions considers why this is a great opportunity for professional installers to become a trusted and practical source of money-saving advice.
Hot headlines Just a decade ago, the average annual household energy bill was £472. Today, it stands at a whopping £1,265, so it’s little wonder there’s a lot of heat in the headlines when they’re talking about energy companies, price rises and the effect they have on cash-strapped homeowners and tenants,” he says. Despite recent small reductions in tariffs, costs remain high or even unaffordable in some circumstances so most are still looking for other ways to cut their home energy usage. continued>>

HIP BOOK 2015-16 | WATER TREATMENT
Yet, ADEY believes one of the simplest steps to save on energy is being overlooked.
Service history Research by ADEY shows that only 46% of the 1,300 UK homeowners surveyed had their boiler serviced in the past 12 months, leaving more than half of systems unchecked. One in ten householders even consider having an annual boiler service an unnecessary expense. This means that every year, thousands of boilers are left chugging away in the corner without checks to ensure that they’re running efficiently or even safely. In fact, 20% of householders only took any notice of their poor hard-working boiler when something went wrong. ADEY believes that having an annual service should be considered just as important as a car’s MOT. While it’s not a legal requirement, it will ensure that the boiler and heating system are running as they should, helping to keep potentially costly repairs at bay and any boiler warranties intact. More importantly, it could also help to keep a household safe from the dangers of carbon monoxide, particularly on ageing systems.
Share the best practice solution Few homeowners will understand that the small parts and narrow waterways of today’s superefficient condensing boilers are prone to the damaging effects of the natural corrosion that happens inside every heating system. However, treating the symptoms caused by debris in the system is an installer’s daily bread and butter.
DID YOU KNOW? Research shows that the presence of just 5kg of sludge within the system, which is not uncommon, reduces radiator heat output by up to 36%.
Installing a MagnaClean filter is proven to reduce system carbon emissions by up to 6%, resulting in a 200-250kg carbon saving year on year. Those installers who can effectively communicate with their customers to help them understand the benefits of ongoing heating system maintenance and protection will reap the benefits. This is one of the many reasons why ADEY developed its award-winning approach to best practice. It enables installers to easily communicate the crucial ingredients for ultimate system protection in four simple steps. ADEY’s recommended best practice follows the maintenance mantra of clean, flush, maintain, protect. The combined effect of system cleaning, quality water treatment chemicals and the most effective magnetic filtration, work to improve heating system efficiency, protect against breakdown and reduce household heating bills. Adopting best practice can also help installers to build a reputation for excellent customer service and encourage repeat business.
Protecting the pounds Statistics from Moneywise, show that typically, a fifth of UK households have a boiler breakdown over the winter, at an average repair cost of £320. However, a new study has highlighted the worrying number of households unprepared to cover these unexpected emergency costs with many admitting it would drive them into debt. Most UK householders (55%) said that if they were hit with a bill for emergency heating repairs of £1,000 or more, they would have to ask for a bank loan to cover the cost. To pay a
WATER TREATMENT | HIP BOOK 2015-16
bill of £250, 49% said they’d have to borrow the money from friends or family and 30% said they’d need to pay on credit card.
By encouraging customers to take steps to maintain and protect their heating systems effectively for the long-term, installers can help them reduce this financial risk and ensure their boiler is ready to make it through this winter and many more.
ADeY Best pRACtiCe BeneFits Following ADEY’s four steps could reduce annual household heating bills by £150-£170
Long-term benefits Today, ADEY MagnaClean filters and MC+ chemicals are collectively protecting three million UK central heating systems helping them operate more efficiently, reducing maintenance bills and cutting emissions. ADEY estimates savings of up to 15% on individual annual household heating bills where its best practice approach to central heating system maintenance is employed, using proven effective filters and high-quality chemicals. That could amount to a saving of £150–£170 a year for the average three bedroom property. Installing a MagnaClean filter is also proven to reduce system carbon emissions by up to 6%, resulting in a 200-250kg carbon saving year on year. This could equate to saving more than 600,000 tonnes of carbon emissions a year which is equivalent to removing more than 126,000 cars from Britain’s roads.
ADEY’s best practice could reduce annual heating bills by up to 15% MagnaClean is proven to save up to 6% a year on heating bills and carbon emissions Adding a quality chemical inhibitor can increase boiler efficiency by 3% Installing a MagnaClean can reduce maintenance call-outs by as much as 37% Best practice protection could increase the life of a boiler beyond 12-15 years

Like all the best inventions, the idea is simple. A powerful magnet removes virtually 100% of the suspended black iron oxide, or magnetite, that builds up in heating systems. The black sludge affects boiler performance and, left untreated, causes breakdowns. Powerful magnets and superior design and engineering set MagnaClean apart and hold the key to effective filtration within an innovative swirl chamber. Small or poor performing magnets will only deliver poor filtration results which could be detrimental to heating systems. ADEY’s growing range of chemicals bring ongoing innovation to the market with the addition of MC1+ RAPIDE Protector and MC3+ RAPIDE Cleaner. Developed by the most experienced technical experts in the sector, the fast single-dose products provide system cleaning and ongoing protection for up to 15 radiators which can be delivered in just 20 seconds. ADEY also offers customers a tailored, responsive and totally reliable online water testing service. For further information visit adey.com
