Staff at Inta, the Stafford based heating and plumbing product manufacturer, have raised over £1150 for the charity Breast Cancer Now when they turned themselves – and their products – pink for a day. From the sales to the technical teams, all took part in a variety of activities to raise money for the cause. As well as wearing head-to-toe pink, hosting a raffle and a pink cupcake auction, staff

also took part in the ‘Great Inta Bake Off’, all in the name of charity. Other competitions included the ‘Get Your Chest Out’ photo challenge, which saw the staff trying to guess the celebrity based on a snapshot of just the chest area. The firm also turned its range of Zilmet Expansion Vessels pink to mark the occasion. To find out more about the Wear It Pink campaign, go to: www.wearitpink.org

Domestic appliance register Shower manufacturer Triton has added its name to the AMDEA (Association of Manufacturers of Domestic Appliances) ‘Register My Appliance’ initiative. The aim is to connect manufacturers with customers so they can be contacted to improve household safety by informing the owners about the safety of their product and arranging the required service or aftercare.

All consumers need to do is visit registermyappliance. org.uk to provide information about any newly purchased products. It is also possible to register older appliances (up to 12 years). David Tutton, MD at Triton Showers, comments: “As the UK’s leading shower manufacturer, we are fully supportive of the new Register My Appliance initiative. Speed

and efficiency are key when it comes to safety, so we will be encouraging our customers – from installers, merchants and retailers to the homeowners themselves – to get on board with the scheme and help to populate this crucial database.” To register both old and new appliances, visit the website: www. registermyappliance.org.uk

Supporting fair pay for interns

Employers who do not pay their interns is tantamount to slavery, and offending companies should be named and shamed for exploiting young people – this is the view of Pimlico Plumbers boss, Charlie Mullins, who has expressed his support for Conservative MP Alec Shelbrooke, who has introduced a private members bill calling for a ban on unpaid internships. According to a recent YouGov poll, 43% of 18 to 24 year olds believe unpaid internships act or have acted as a major barrier to get a job.

Charlie says that not paying interns puts young people from less well-off backgrounds at a disadvantage. He says: “Unpaid internships put poorer candidates at a disadvantage because they just cannot afford not to work, compared to their richer peers. There is no excuse whatsoever for allowing someone to toil on your behalf and not pay them just because you can. This kind of behaviour must be made as unacceptable as not paying the national minimum wage. This is why I’m 100% behind Alec’s bill.”

ELECTRIC SHOWERS THAT LAST 50% LONGER Mira Clearscale™ Technology Unlike competitor products all our electric showers feature Dual Element™ heater tanks. Two separate heating elements are wound together in a coiled helix, this increases space for water to flow and gives a more even distribution of heat, reducing hotspots where limescale can build up.

12 NEWS Review Continuous flow technology study

Open Day puts LPG in spotlight More than 85 installers from across the country attended Calor’s Open Day at its National Training Centre in Stoney Stanton, Leicestershire, last month. Domestic and commercial heating engineers were there to learn more about LPG and network with sales reps and other installers. The event included a number of partner organisations including Adey Heating Solutions, Danfoss, Greengear, Honeywell and Rinnai who were on hand to give advice. Installers were also able to attend a wide range of presentations and training sessions, covering topics such as how LPG compares to other rural fuels, bulk tank and cylinder siting regulations, as well as learning more about the Calor Installer Incentive scheme. Ian Digby, Specifier Sales Manager for Calor, says: “I am really pleased that we have been able to build on last year’s open day and deliver an event which highlights the efforts we are making to build relationships with local installers.”

Continuous flow water heating systems can be up to 7% more economical than equivalent traditional stored hot water systems, according to an independent study carried out by AECOM. Rinnai commissioned the building engineering services consultancy to carry out a life cycle study over 20 years on continuous flow water heating systems, and to provide a comparison with conventional storage systems. Continuous flow water heating systems were compared to direct and indirect fired storage systems in two case studies. AECOM then determined an equivalent storage based system for each case study and compared operational and capital costs. The report found that in both cases the continuous flow system had a clear advantage in terms of initial capital costs, as well as life cycle costs over 20 years, with the continuous flow

annual fuel costs and estimated servicing costs, the resulting net present values of the three showed that the continuous flow system was 6 to 7% lower than the two storage systems based on that 20 year period.

system consistently lower in energy use than the two storage systems. The first case study was modelled on a small, prefabricated fast food restaurant. It assumed that the system only served the hot water demand. Taking into account the assumptions regarding initial capital costs, projected

The second case study analysed a system for a shower block in a holiday camp with six showers and four basin taps. For the continuous flow option, the study was based on a configuration of four continuous flow water heaters that each had a nominal output of 48kW. For this particular application, because there was a very short run of pipework between the water heaters and the fixtures, it was possible for the water heaters to generate water at 40°C. The risk of legionella was overcome by regular system flushing. For the energy required to

deal with the instantaneous hot water demand, the analysis assumed that the bulk of the hot water demand would be from the showers. Each shower typically had a flow rate of around 9 litres per minute, which if mixed to 40ºC would equate to an instantaneous load of around 19kW each. So even if there was only one shower running, the load on a single continuous flow water heater would equate to an efficiency of 95% based on the performance curve. As the hot water demand increased, the modular nature of this particular configuration allowed the 95% efficiency to be maintained for the bulk of demand. The difference in daily fuel costs between the three systems was around 7%. The usage profile for this case study is particularly suited to continuous flow systems, which allow for high but infrequent demand over the day.

NEWS Review 13 BMA conference highlights evolving economy The famous Belfry golf course and hotel facility in Sutton Coldfield was the setting for this year’s Bathroom Manufacturers Association conference, with the benefits and ramifications of a circular economy top of the agenda. The circular economy is described as an alternative to a traditional linear economy, where resources and products are used for as long as possible and are recycled at the end of their service life. Consumer behavioural change, sustainability, globalisation, waste management and new business opportunities were just a few of the topics addressed by the line-up of informative speakers, with BBC news presenter Sophie Long in charge of proceedings and leading the discussion. Climate change expert Chris Goodall was first on the podium, highlighting the serious issue of rising world temperatures and what manufacturers and consumers can do to help alleviate the problem. Chris informed delegates

that consumer attitudes are key, siting the increasing number of people who are likely to purchase products on the basis of their energy efficiency rather than any other criteria. He argued that UK shoppers will come to view durability and a low carbon footprint as more important than fashion when it comes to purchasing products for the bathroom. Behavioural scientist Marc Atherton was next on stage, offering advice on how businesses can influence consumers. “Companies need to make it easy, desirable, rewarding and habitual for consumers to buy sustainable products,” he said. Tim Pollard, Head of Sustainability at Wolseley UK, spoke about the issue

of the circular economy from the point of view of the merchant. He pointed out that it’s one thing for a

product to be recyclable and quite another for it to actually be recycled. He also put forward the case for a new business model that could see future manufacturers selling ‘heat’ rather than the heating product itself. Professor Margaret Bates, a Professor of sustainable waste management at the University of Northampton, argues the case for more of a focus on the energy used during the production

process and pointed out that the European economy could save £630 billion each year through the better use of resources. Concluding the conference, motivational speaker Steve Head inspired the audience to strive to do 20 things 1% better rather than do one thing 20% better. His entertaining and interactive presentation helped to ensure that the event ended on a positive note.

Conference Host, BBC News presenter Sophie Long

Happy anniversary This year’s conference also marked the 15th anniversary of the BMA. Formerly the Council of British Ceramic Sanitaryware Manufacturers, the organisation was formed in 2001 and originally consisted of 15 members. Today the BMA represents over a hundred different brands and has evolved from a ‘cosy gentleman’s club’ to a proactive group that lobbies decision makers on behalf of the industry and campaigns on important issues such as water saving and the prevention of scalding.

The picture shows Yvonne Orgill, Chief Executive of the BMA, with current President Paul Massey cutting into a cake to celebrate the Association’s milestone. ENQUIRY

Scottish students showcase solar energy innovation Plumbing and heating students and staff from West College Scotland’s Greenock campus have demonstrated a new advance in solar heating technology at the recent ‘Colleges delivering a stronger economy and a fairer society’ event at the Scottish Parliament. SunampPV, created by tech entrepreneur Andrew Bissell, is a heat battery that can store solar PV energy to deliver hot water without the need for a hot water cylinder and immersion heater. The students, who are currently studying for their SVQ Level 3 in Domestic Plumbing and Heating, need to have a full understanding of the role renewables play in heating and ventilation systems, and have built a rig to demonstrate how SunampPV, with an Intergas HRE boiler, can provide a low carbon solution to heating water using the electricity generated that would otherwise be exported to

the National Grid. When water temperature coming from the SunampPV starts to drop, the boiler progressively modulates up to maintain the desired temperature. Harry Hunter, Curriculum and Quality Leader for Engineering at the campus, says: “The students were great ambassadors for the college and a credit to the companies they are apprenticed to. They took the time to explain how the system operated in a way that everyone could understand and now they’re

spreading the word further as they ‘tour’ with the rig to other colleges in Scotland.” MD of Intergas Heating, Stephen Zouch, says he is delighted to see its HRE boiler being used in an educational scenario. He comments: “We need curious people to help us continue to deliver efficiency without forgoing comfort. Showing other students how ingenuity and simplicity can achieve outstanding outcomes is inspiring and just what our industry needs.”

BUSINESS Matters

Wetrooms made quick and easy The latest wetroom formers can be installed with the minimum of fuss in a variety of applications, from care-adapted installations to luxury bathrooms. James Dadd, Marketing Director at AKW, explains.

s a busy bathroom installer you no doubt have a variety of business objectives. They might include, for example, providing a personalised and bespoke service, offering a high quality finish, ensuring the best accessibility to and from the bathroom, and making as big a contribution as possible to the safety of users. These are all admirable customer focused aims, but there is also another equally important goal if you want to maximise the potential of your business – fast, hasslefree installation. This is particularly true of wetrooms, which can be a challenge to install using conventional means. Forming the required gradient in a wetroom is traditionally achieved with pieces of plywood or by eye in a concrete screed. However, it is simpler to use a purposedesigned underfloor solution – the wetroom former – which provides the correct drainage levels and gradient to the waste. Because it offers a greater degree of accuracy, a former also minimises the chances of making an error, saving significant installation time. Wetroom formers are quick and simple to fit, provide unrestricted access to the showering space and can offer aesthetic advantages (with different options for glass screens). They also boost flexibility in design and use. In some cases, for example, the former may be built into a bathroom during

construction with the waste positioned for connection to a bath. If the needs of the user change, the bath can then be removed and the room converted for level access showering at minimal cost and with little disruption.

Flexible solution The advantages of wetroom formers don’t end there. They are also useful in situations where the shape of the bathroom or the location of existing drains limit other options. On top of this, formers can easily be modified to fit odd shaped rooms, and an offset drain hole in modern designs allows the former to be rotated to accommodate different drainage positions and configurations. Some models, such as the TuffForm from AKW, can be cut into floorboards and placed straight onto the joists without the need for under-boarding. Cutting the formers into the existing floor boards permits perfectly level, step-free access when combined with 4mm ply on the remaining area. Modern

Wetroom solutions from AKW With 26 years experience, more than one million satisfied customers worldwide and products used in over 35,000 wetroom installations every year, AKW is the market leader in innovative, easy-installation wetroom solutions. Its highly durable formers – TriForm, DuraForm, SureForm and TuffForm – offer a wide selection of size and price options, designed to provide the perfect gradient to ensure optimal drainage. AKW’s formers make installation stress-free and help to create the perfect stylish wetroom for any budget or lifestyle requirements.

wet floor formers also allow the installer considerable flexibility with the location of the waste. Our SureForm product, for example, has an offset waste position and can simply be rotated by the installer to avoid underlying joists or pipework. DuraForm, meanwhile, is an affordable former that is surprisingly light in weight, easy to handle and simple to trim to an exact size. DuraForm has the added benefit of having an offset waste. It is available in seven standard sizes and has a load capacity of 25 stone. However, in some situations, it might be necessary to accommodate extra loads in the wetroom. For example a disabled occupier might have to use heavy mobility aids such as a wheelchair, or perhaps the extra load capacity will be needed to allow a carer to enter the room to assist with washing. That is where products such as our TriForm former can help. This is specially designed to support loads of up to 40 stone, making it suitable for just about every bathroom application. Smart design details include waste positioning, high flow rate options for drench showers and top access wastes. TriForm can accommodate high shower flow rates of up to 78 litres per minute and is available in five sizes with three waste options. And, like all AKW formers, it comes with a 25 year guarantee.

Plumbers falling prey to theft A survey of plumbers has revealed that 42% have had their vans broken into. In its Healthcheck of the UK’s tradespeople and small contractors, ECIS found that 46% of the plumbers it surveyed leave their tools in the van overnight, and 42% had gone through the disruption and cost of having their van broken into. In addition, 38% have no branding on their van, missing out on the chance to market themselves and promote industry accreditations. The survey found that plumbers were one of the trades most likely to be targeted by thieves. Close to half of all trades surveyed (45%) do not remove even the most valuable tools from the van when it is left unattended overnight.

The volume of thefts being experienced does not appear to have a direct correlation with van branding, according to ECIS. 66% said they have branding on their van – up from 60% last year. Paul Guiry, CEO of ECIS, says: “The van is an essential tool in the plumbing sector,

yet many of the plumbing contractors we spoke to are not protecting their vans from the risk of theft. Simple precautions, such as removing tools at night and displaying a sticker stating that tools are not left in the van, can go a long way in reducing the risk.”

Card payments no problem New research by mobile card payment app, SmartTrade App, has revealed that one of the greatest barriers to earning a living for small businesses is the inability to – or the expense of – handling credit and debit card payments. More than half (55%) of all small traders claim to have lost business through a lack of card payment provision, according to SmartTrade. For a third (33%) of small traders the cost involved was sometimes prohibitive, especially now that Visa has

removed the interchange cap on debit cards, meaning that certain businesses now have to pay up to six times more per transaction. The app provided by SmartTrade requires no special equipment other than a smartphone. The company offers a 0% transaction fee feature, where small businesses can pass or split the cost of the card fee with the customer to get lower rates. It also enables paperless tracking of invoices, which can be integrated with bookkeeping programmes.

Chief Executive Keld van Shreven says: “We conduct regular customer satisfaction surveys at SmartTrade and we’re thrilled to find that 89% of our users have found the app a useful tool for managing cashflow, while a further 83% said that it was much easier for them to collect payments using the SmartTrade App than with other providers, or simply handling cash.” To find out more, please visit the website: https:// smarttradeapp.com

38 COMPANY Spotlight

The experts in independent living As an established name in the healthcare sector and experts in level access showering, N&C is well placed to help installers meet the growing demand for wetroom solutions. PHAM News recently met with Director Richard Hill to find out what the company has to offer.

ith an ageing population and the increasing requirement to provide care within the home, the ‘independent living’ sector is one market that continues to grow year on year. Naturally enough, the number of companies looking to meet this rising demand has also grown but N&C, with its Phlexicare brand and wetroom solutions, is Company Director Richard Hill confident that it can offer customers a level of service that other companies will find hard to match. The British manufacturer and distributor, with head offices in Chadwell Heath, Essex, can lay claim to pioneering many of the healthcare solutions that are today taken for granted, such as the raised height WC pan, low entry shower tray and half height shower doors.

New market Founded in the East End of London in 1875, the family owned business has its routes in the glass market and the distribution of building materials, but it’s the Phlexicare brand, first introduced in the 1970s, that opened up a new specialist market for the company that hadn’t been recognised by other manufacturers. “There was a realisation that products needed to be adapted to suit the disabled, which really wasn’t being done at all,” says Sales Director Richard Hill. “In effect, we helped to found the accessible products marketplace which didn’t really exist at the time. We were the first to manufacture the raised height WC pan. We were working with occupational therapists and couldn’t understand why it should be the case that someone with a wheel chair had to struggle and lift themselves back onto their wheelchair because the toilet’s too low. An extra two inches in height made all the difference.” Responding to customer demand, the Phlexicare brand has evolved over the years, with the range of product solutions extending from the bathroom to the kitchen and then on to general access products. The company is able to offer bespoke solutions to suit the needs of the individual, designing products for a particular property that will help to maximise freedom within the home. A requirement for level access showering has primarily

been associated with the healthcare sector, but in recent years consumer demand for wetroom solutions in the bathroom mean that it is now very much part of the mainstream market. A growing number of homeowners are looking to benefit from the extra space that a wetroom provides and recognise the advantage it offers when it comes to providing a bathroom that’s easy to use by all members of the family. “We all know that the majority of bathrooms in the UK are very small, so freeing up some of that space is key,” says Richard. “We are hot on ‘inclusive design’ and we spend a lot of time, money and tooling to develop this style of product. Our Freespace concept, for example, looks like a wetroom system that anyone would aspire to have in their bathroom. It doesn’t look like it belongs in a care home. It’s a high quality domestic style product with additional benefits. We are manufacturing design led products that cross over and can be used in the home by two or three generations, regardless of their mobility.”

Circulating Pumps & System Treatment 41

What’s the true cost of the pump you install? Looking to save money at the point of purchase may not always be the best policy. Steve Schofield, Director and Chief Executive of the British Pump Manufacturer’s Association (BPMA), explains how life cycle costing can help to reveal the true cost of a pump.

he need to cut costs wherever possible is an increasingly familiar requirement for engineers charged with ensuring the continued smooth operation of plant on a limited budget. When it comes to pumping systems, although choosing the lowest cost option may seem like the best short term solution to achieving cost savings, it will almost always result in additional costs being Steve Schofield, Director and incurred that could have Chief Executive of the BPMA been avoided by spending a little more time and money during the specification and design stage. According to statistics from the US Department of Energy’s Office of Industrial Technologies, pumping systems can account for between 25 and 50% of the total energy consumed by certain industrial processes. Add to this the need for ongoing service, repairs and maintenance throughout a typical service life of 20 years and pumps quickly begin to represent a substantial area of expense. The expectations of some pump users can be unrealistic when it comes to the cost of pump ownership. In many cases they focus too much on initial outlay, opting for the least cost alternative, which is not always actually the best solution for the application.

Cycle costing So what is the answer? The BPMA and many of its members are keen to emphasise the importance of life cycle costing (LCC) as a vital part of any pump purchasing and ownership strategy. Life cycle costing takes into account many factors, all of which impact on the total cost of owning and operating a pump, which includes much more than just the initial outlay. A pump’s life cycle cost encompasses the total overall costs that accumulate throughout the life of a pump, from installation, energy consumption, operation, maintenance and down time, even through to the final decommissioning and disposal of the pump. By carrying out an analysis of the costs that are likely to be incurred throughout the operational life of the pump, it is possible to objectively compare all the potential options at the outset. Life cycle costing can be useful not only for selecting new equipment but also for justifying the upgrade of existing systems. Throughout the lifetime of a pumping system, it is unlikely that the same operating conditions will continue to prevail. Factors such as the addition of new equipment upstream of the pump can cause variations in pump duty away from the pump’s ‘Best Efficiency Point’ (BEP). This is the point where pump capacity and head pressure combine to provide the maximum efficiency performance from the pump. If the pump is incorrectly sized and is operating too far from the BEP, wear and tear can occur which can shorten its operational life. An oversized pump, for example, will not only be inefficient, but will also cost more to maintain because operating too far to the left of its performance curve puts an extra strain on pump bearings and seals. On the other hand, a pump which is undersized for the duty may end

Getting it right The following are just some of the key factors that should be considered when specifying a pump, which could help ensure it delivers optimum performance and economy throughout its service life.

1. What sort of pump is required?

It is estimated that 85% of the life cycle cost of a typical pump is related to the daily operation of the pump

There are many different types of pump available, each of which is suited to particular applications. The two most popular types are centrifugal pumps and positive displacement pumps. Centrifugal pumps are generally suited to fast flowing or low viscosity liquid applications where the pressure is relatively constant. They perform most efficiently and cost effectively when operating at or near their Best Efficiency Point (BEP). Positive Displacement pumps, on the other hand, are particularly ideal for high viscosity applications, as they are better able to maintain a constant rate of flow. Information on selection and which pump is best suited /used on different applications can also be found within the BPMA buyers guide available on our website.

up running too quickly, which may potentially ruin the product being pumped and also prematurely wear out parts of the pump. Also its efficiency will be affected, resulting in excessive energy consumption. Although a pump should be sized to an application, achieving this is not always straightforward. Involvement 2. Is there sufficient pressure for it to work effectively? of third parties and the need to meet possible changing The efficiency and operation of centrifugal pumps in future requirements can all affect the sizing of a pump. particular can be affected by the Net Positive Suction Head (NPSH) available. Basically, this is the amount of pressure Over-design on parameters is very commonplace. If every party involved in specifying a pump adds on that is required to prevent the liquid being pumped from even a small percentage to their sizing estimate, the end vaporising inside the pump. If the liquid vaporises, bubbles can be formed which will result can be a highly inefficient pump. The extra cost, both in terms of running and maintaining the pump, can be carried into the pump. When these bubbles encounter zones of higher pressure in the pump, they will collapse be very high over the life of the plant. To help with changes in duty and assist with energy violently, resulting in a phenomenon known as cavitation, which can severely damage reduction, many pump the pump. When designing a manufacturers are now “Simply upgrading a pumping system pump system, it is essential promoting the use of Variable can result in energy savings of up to 50%” to ensure that the available Speed Driven pump systems, pressure on the pump inlet frequency drive being the most prominent system used. By using VSDs you in effect is greater than the pressure required within the pump to avoid the occurrence of cavitation. combine electrical and mechanical principles.

Is the pump positioned in the correct place? can often help boost efficiency and enable pumps to meet Where a pump is positioned within a pipeline can also changes in demand at a fraction of the cost of building a greatly affect its performance. As well as determining the new system from scratch. In some cases, simply upgrading amount of pressure available, the positioning of a pump a pumping system can result in energy savings of up to 50%. can also affect the quality of the product being pumped.

System design

Maintenance and energy consumption represent by far the two most significant costs throughout the life of a pump. The answer to minimizing these costs lies in ensuring a welldesigned system, where the pump is specified to meet the demands of the application. Every pump manufacturer can, or should, supply characteristic curves for their equipment illustrating pump performance under given conditions. These curves demonstrate the inter-relationship between discharge capacity, pump head, power and operating efficiency. To address possible energy savings, in 2010 the BPMA created the CPSA scheme (Certified Pump System Auditor). The objective of the scheme is to help improve the levels of professionalism in the sector by creating a universally recognised and respected industry ‘standard’ for individuals assessing the performance of a pumping system. The CPSA Scheme training includes: • Pump System Requirements & Analysis considerations • ISO 14414 Pump System Energy Assessment Standard Requirements • Pump System Optimisation methods

Too much or too little distance in the pipeline before the pump, for example, can lead to friction losses which can affect the flow rate of the substance being pumped, which in turn can affect efficiency. The presence of pipe fittings, such as elbow joints, filters or other in-line equipment, can also affect the flow rate of a substance to the pump.

4. Don’t just purchase on cost alone When it comes to selecting a pump, cheapest is by no means best. Be particularly careful where reductions in the purchase price have been achieved by cuts in supplier back-up and expertise. Ultimately, the most cost effective installation will be the one where the supplier can offer good technical back-up.

5. Always take the pump manufacturer’s advice It’s surprising how many customers don’t take advantage of the expertise available from the pump manufacturer when it comes to ways of getting the best performance from their pumps. After all, nobody knows more about how to get the best out a pump than the company that built it. www.bpma.org.uk

42 CIRCULATING PUMPS & System Treatment

Magnetic filter design continues to evolve The market for magnetic filters has grown rapidly in recent years. Here, Richard Wall, Technical and Product Director at Fernox, tracks the recent evolution of design and offers a guide to how products are brought from the conceptual stage to the merchant’s shelves.

he idea of chemical water treatment within the heating industry dates back to 1964, when German engineer Peter Muetzel pioneered its use as a way of dealing with dirty, inefficient central heating systems. Since then, the sector has continued to evolve and f lourish. However, the practical and functional benefits of the first corrosion inhibitor are still as relevant today as they Richard Wall from Fernox were a half-century ago and its introduction directly led to further developments in the field of water treatment for heating systems, including the widespread adoption of filters.

Best practice When first introduced, filters may have been viewed by some as useful but not always necessary. Now as our understanding of their capability has grown and filter performance has evolved, it is rare that a professional installer would not recommend the inclusion of a filter regardless of the type of heating system. In addition, filtration is widely considered best practice by many boiler manufacturers. In fact, today, filter technology is so embedded within the heating industry that it is included in the supplementary information of the Domestic Heating Guide, which states: ‘a filter can also be fitted to the central heating circuit to

help maintain the efficiency and reliability of the system’. Consequently, the water treatment filtration market has become crowded with new products. This makes it problematic for installers to match the right product for the right application and to be sure of specifying filters of the highest standard. So what makes a filter stand out from the pack?

‘in the field’, while also ensuring the product has met all necessary health and safety requirements. Following research, development, testing and optimisation, the filter is finally ready to be manufactured and distributed. However, the journey should not end there. Customer feedback and ongoing testing needs to continue in order to reaffirm existing products still meet market criteria.

Team effort

End product

Central to any product development are the product management, sales and technical teams who will determine the problems or issues installers face on-site that could potentially be resolved through filter design. Once consensus has been reached on clarity of purpose and market requirements, a research and development team is deployed to compile product specifications. Installers might be surprised to learn that from here it can take a significant time period to deliver a reliable filter that meets all the stringent quality standards and market requirements. The process can be especially time consuming, as there are multiple practical and contextual factors to be considered. For example, at Fernox it is the belief that to be truly effective, a filter should capture and contain both magnetic and non-magnetic contaminants. At the product planning stage a lot of emphasis is placed on how to make a filter quick and easy to install and clean. From the installer’s perspective, how it fits onto pipework is a critical factor. It is always recommended to look for filters that can be installed either horizontally or vertically onto pipework to provide the flexibility often needed when work begins on site. Manufacturers will also need to take into account the pressure and flow requirements, the temperature rating, as well as the pipe sizes required in order to install the filter.

An example of a product that has undergone this extensive process, is our new TF1 Omega Filter. The first nickel-plated brass filter produced by Fernox for the domestic market, the TF1 Omega Filter combines a powerful, neodymium magnet with Hydronic Particle Separation (HPS) technology. This method of cleaning optimises flow trajectories and enables particles to settle at the bottom of the filter. As such, the filter is capable of extracting high levels of system debris, retaining them safely for rapid, easy removal. The result is an improved level of boiler protection and system efficiency. The TF1 Omega Filter has been designed to help reduce installation time and provide extra flexibility. Ideally fitted onto the return pipe to the boiler, the filter can be installed horizontally or vertically on 22mm and 28mm pipework in both flow directions, and may be positioned at a 45° angle if required – making it fast to install even in confined or awkward spaces. Additionally, it is supplied either with nickel-plated high-quality valves or a slip socket connection, offering the installer superior choice.

When all the multiple factors have been evaluated, the filter prototype is developed and testing commences. As much as companies are eager to be first to market, it’s important to conduct extensive and rigorous testing that replicates any circumstance or variable that might occur

Easy cleaning Furthermore, cleaning the TF1 Omega Filter is a fast and tidy process, which can be completed in situ, with no need to remove the lid or dismantle the unit when extracting dirt collected by the filter. Water treatment chemicals can also be added via the filter in less than 30 seconds using the Fernox Express range. It is important to remember that a filter works best when used in combination with effective chemical water treatments. Together, the products protect the life of the boiler and prevent the formation of further scale and corrosion within the system. www.fernox.co.uk

Testing facility delivers results If you want to know how much inhibitor is already in a system or what treatment needs to be added, Adey’s water testing service will provide you with all the information you need. PHAM News recently visited the company’s Kent based laboratory to find out more.

ith extended w a r r a nt i e s for domestic boilers now commonplace and greater awareness about the benefits of maintaining a clean central heating system, the need to know about the quality of the water in that system becomes all the more important. The water testing service from Adey has been designed to provide the answers. Two years ago the company invested in a new research centre and laboratory based at the Kent Science Park in Sittingbourne. The R&D facility is the first laboratory in the HVAC sector to be accredited by UKAS (the United Kingdom Accreditation Service) for the testing of central heating system water and it continues to expand its resources in response to increasing demand for its services.

“With boiler manufacturers increasing warranties, we’re seeing more stringent criteria against which they will be honoured,” says Mo Jassal, Adey’s Chemical Technical Manager. “Water testing is now becoming more crucial than ever across our sector to keep these longer-term warranties intact and we’re fully equipped to meet this demand. It’s the first port of call for a manufacturer to check water quality and confirm that correct installation and maintenance procedures have been followed.”

Adey’s water testing service employs a team of highly qualified analytical chemists. Installers can pick up test kits from their local merchant, then send them to the lab using the pre-paid envelope. Test results will then be made available via a secure online portal, usually within 24 hours, with a full analytical report, detailing system problems and recommended solutions.

On the level

The tests are completed on a broad range of test parameters, including the determination of corrosion products, scale deposition, pH, chloride, conductivity and inhibitor levels. “A fast turnaround is important because some contractors may only get paid once water testing has been certified,” explains Mo. “Our turnaround is much faster than the competition and our facility is capable of carrying out 200 samples a day.”

Mo Jassal, Chemical Technical Manager for Adey

The water testing service has been taken up by a growing number of local authorities and contractors who want to ensure that installers are adding the correct levels of inhibitors and system protection. Mo reports that current testing typically reveals a 10-15% failure rate, although this has started to decrease as installers gain a better understanding of what needs to be done.

“The key message for installers is that the adoption of a best practice approach provides an opportunity to grow their business,” adds Mo. The company is proud of the fact that it is the only lab in the industry to be UKAS accredited. “It underpins our technical competence and integrity of both our water testing service and inhibitor performance testing,” says Mo. “This sets us apart, giving confidence to our customers that we are leading the way in raising quality standards. “We’re working to a level that is unprecedented in the industry. It underlines our commitment and investment to pushing the bar in terms of quality. We’re continuing to expand and invest in the team and the lab, and the level of resource we now have is allowing us to maintain the highest standards.” PHAM NEWS ENQUIRY No.

Why put up with inefﬁciencies? Cascade systems are a popular solution for light commercial environments, but to maintain performance it’s important to consider the benefits of dirt separation and deaeration, as Roger Williams, Commercial Support Manager at Spirotech UK, explains.

he drive towards greater efficiency has propelled the UK from being the dirty man of Europe to one of the most forward thinking in terms of its energy reduction aspirations. One positive result of this has been the steep decline in large cast iron boilers that once dominated the market – models which have since been replaced with advanced condensing units. In the commercial and light commercial arena, or for large domestic properties or office buildings, the move towards the same high efficiency boiler model has been no less prominent, yet boiler size and greater output requirement are factors that ultimately affect future maintenance. This desire to marry high output demand with energy efficiency has led the semi commercial market down the cascade boilers route, offering a practical alternative to changeable output demands.

In a cascade (otherwise known as master and slave) system, boilers are connected together hydraulically with sequence or step controls to more accurately monitor energy demand. Most importantly perhaps, a cascade will also improve the efficiency of the system, as individual boilers can be turned on and off according to demand. The old cast iron boilers may have been supreme energy wasters, but they were robust and would rarely breakdown or malfunction. By contrast, modern boilers are energy efficient but highly sensitive to contamination and rely on clean water running through them to maximise performance. Water quality can be compromised by a number

of factors, the biggest of which is dirt, which will f lourish if air is not being constantly removed from the system.

Fully protected Cascade systems can be designed with as few as two or as many as six boilers as part of the set up, but research has shown that reliability is optimised for systems with four to six boilers within a cascade. In terms of efficiency, there is no appreciable difference between several small, or one or two larger boilers. Regardless of the number or size of boilers installed, it is important to be aware that each one is at risk of the same contaminant problems, so each needs to be fitted with the appropriate safeguards, which in the case of dirt removal means a dirt separator should be fitted on all units to ensure adequate protection. Whilst cascade systems are beneficial for more accurate heat control and output management, there is a greater overall risk of faults occurring in a system made up of several boilers, which makes the need for full protection all the more pertinent. Depending on the demand and size of the building, individual deaerators should be used in conjunction with an appropriate dirt separator, such as the Spirotech MB3 unit.

Deaeration can sometimes take a backseat to dirt separation in terms of installer priorities, but for new installations, where cascade systems are installed, it’s advised that dirt separation and deaeration be installed. A deaerator works by continually removing the air, including microbubbles, from a system, which, if left, will speed up the growth of magnetite. This approach should always be taken in accordance with the correct system set-up, which should also include appropriate chemicals treatment. If the building is large or multi storey, installers should also consider system pressure requirements, as it may be necessary to install a vacuum degasser, rather than individual deaeration units. The degasser would be set up to work alongside the boiler cascade and would work in accordance with the output of one or multiple units, depending on demand. Where a cascade system is replacing an older boiler, it’s advisable that both deaeration and dirt separation be installed, as historic dirt will likely be circulating in the system.

Bigger issues Whilst the sophistication of control and volume output is greater for cascade systems when compared to standalone installations, the same principles of good maintenance must apply. A thorough understanding of air and dirt, and an acknowledgment of the greater impact they have as the pipe network gets larger, is the key to enhancing efficiencies, and installers should therefore make sure that they scale up the dirt separation and deaeration requirements in line with size and output.

Offering a full protection service The offering of a system cleaning and maintenance service can help installers get ahead in a competitive market and, at the same time, deliver superior, lifetime protection for their customers. Daniel Cheung, UK Trade Marketing Manager at Sentinel, explains more.

ith over 120,000 registered gas engineers and tens of thousands of plumbing and heating firms in the UK, competition for domestic business can be tough, to say the least, and standing out from the crowd a very tricky task. For those that don’t wish to enter into endless price wars, which often only serve to squeeze margins and compromise quality, expanding your Daniel Cheung, Sentinel’s UK business and winning new Trade Marketing Manager customers relies on offering services that exceed what’s available elsewhere in the market. So, how about a ‘bells and whistles’ water treatment package which guarantees lifetime protection from corrosion and limescale induced problems, such as inconvenient breakdowns, costly premature repairs and parts replacements, cold spots on radiators, higher heating bills and loss of boiler warranty? A service such as this is certain to appeal to homeowners, who value the benefits of an efficient, optimally-performing heating system, such as peace of mind, a warm home, and cost savings. Moreover, delivering lifetime protection would be a real point of differentiation for any plumbing and heating company. This point is underlined by research from a major boiler manufacturer, which found that 87% of boiler call outs were to systems without correct water treatment. The best news is that achieving lifetime protection from corrosion and limescale related issues is relatively easy. All that’s required is a strict adherence to the best practice system of clean, protect and maintain, along with the use of suitable, high quality, boiler manufacturer endorsed water treatment products. This diligent approach is lacking in the industry at present. For instance, water treatment maintenance is often skipped altogether, while many

A water testing kit makes it possible to identify the existing inhibitor levels in any heating system

engineers fail to adequately clean heating systems before adding inhibitor. However, correctly carrying out each step of the best practice system is critical for long-term protection, and understanding why is vital when it comes to explaining the service, and its benefits, to customers.

Clean start Let’s start with cleaning: this process removes debris from a system and prepares it for protection. Debris of any kind is bad news for a heating system. For example, independent research by Gastec@CRE found that sludge build-up in domestic system radiators reduces overall effectiveness by typically 15%. Other debris-related problems can include wear and premature failure of pumps, valves and heat exchangers, and restricted water circulation. The Building Services Compliance Guide to Part L stipulates that systems should be thoroughly cleaned and flushed before the installation of a new boiler. Whether a gravity flush, mains water pressure flush or powerflush is required will depend on the type and severity of accumulated foulants. Effective cleaning also means using a chemical cleaner that is specifically designed for the age and type of system, and intended to tackle the type of contaminants present. For example, new systems will require an agent that is able to clean away flux, greases, copper swarf, oil

New time saving aerosol dosing can The new Rapid-Dose aerosol from Sentinel features a preassembled adapter and ‘twist and dose’ mechanism (there’s no need to depress a lever or trigger) that allows easy hands-free dosing of a system in just 30 seconds. The no fuss, mess-free cans are available with the company’s Sentinel X100 Inhibitor, X400 High Performance Cleaner and Leak Sealer chemicals, and can be tried out on a no-risk basis since installers who don’t like the new Rapid-Dose can claim a free bottle of X100 Inhibitor from Sentinel (subject to terms and conditions). Not that Sentinel expects this to be the case: “We have total confidence that installers will love the new Rapid-Dose. It saves time

on site, is incredibly easy to use, can be connected to multiple locations on a system, and there’s no loss of product or spillage,” says Daniel Cheung, UK Trade Marketing Manager. The Rapid-Dose adapter can be used in a number of locations, such as via a radiator, male filling loop stop valve, bleed valve, boiler drain valve, and many filters (via the vent pin), providing extra flexibility when working on awkward or difficult to reach systems. To use Rapid-Dose, installers simply couple the adapter to a system before engaging the twist and dose can – made possible

thanks to the bayonet design that attaches the adapter to the can. A non-return feature, back-check bullet and visible confirmation of dosing all serve to make the process as simple as possible. The Rapid-Dose packaging has also been updated to reflect Sentinel’s best practice System of ‘Clean, Protect, and Maintain’. The RapidDose can for X400 High Performance Cleaner features an easily identifiable ‘Clean’ logo, whilst X100 Inhibitor and Leak Sealer cans have ‘Protect’ and ‘Maintain’ logos

respectively. With these updates, installers can select the right product for the job at a glance and ensure the delivery of best practice water treatment. “Like all of our products, Rapid-Dose was developed alongside installers to find out what they want from a water treatment product,” adds Cheung. “For dosing, the engineer’s wish list comes down to easy and simple operation, speed, no mess, and comprehensive options for awkward systems. RapidDose ticks every box. “It represents another step forward in best practice water treatment solutions that can help deliver lifetime boiler and system protection.” PHAM NEWS ENQUIRY No.

Any system should be thoroughly cleaned and flushed before the installation of a new boiler

and other installation debris, while older systems will need a chemical cleaner suitable for shifting thick, heavy sludge and baked-on corrosion. Debris and other contaminants may also prevent an inhibitor from working effectively, which is another reason why a thorough clean and flush is so important. This leads on to the second step in the best practice approach, protection. Here, a high quality chemical inhibitor – one that is proven to protect all metals commonly found within heating systems – should be used, dosing to a sufficient level. For added insurance, a filter that captures both magnetic and non-magnetic debris, such as a hydra-cyclone filter, can be installed.

Maintenance plan Finally, maintenance – which should be undertaken regularly, perhaps alongside annual boiler services – catches and corrects any potential problems early, ensuring that allimportant ongoing protection. Maintenance is necessary because corrosion and limescale can arise even after best practice cleaning and protection if the heating system is subject to mains water makeup and/or air ingress (which can happen with a change of radiator, poor closed system design, a faulty pump, inadequate pressurisation, etc). The first port of call in any maintenance visit is to check inhibitor levels in the circulating water using a quick test kit. If inhibitor concentration is found to be insufficient, the cause should be investigated and inhibitor topped up. Innovative rapid dosing aerosols, such as those with preassembled adapters and hands-free dosing mechanisms, are ideal for use on service visits since these can dose inhibitor, cleaning chemicals and leak sealer (if required) within seconds. The filter, if fitted, should also be cleaned. Most heating and plumbing engineers incorporate inhibitor dosing on new boiler installations, but few include best practice cleaning and maintenance as well. While the prevalence of inadequate water treatment is unfortunate for homeowners, it represents a real business opportunity for any installers able to offer a superior, lifetime protection water treatment service. www.sentinelprotects.com

50 CIRCULATING PUMPS & System Treatment

Preventing Pseudomonas The waterborne bacteria Pseudomonas is a common cause of poor water hygiene and HVAC system fouling. Steven Booth, Associate Director for Guardian Water Treatment, explains the risks and how to avoid them.

ou may have heard Pseudomonas referred to as the ‘London problem’, but, increasingly, this bacteria is being found in heating and chilled water systems throughout the country. Prior to a rise in testing over the last decade, Pseudomonas bacteria were of little concern and not often investigated, but it is now a priority for closed water system hygiene. In closed circuit systems its risks to human health are minimal, however the corrosion and blockages it causes, particularly in larger-scale buildings, are a problem which has to be tackled at the design and installation stages in order to assist with future water clarity. Ongoing maintenance is also essential. There is one strain of the bacteria, Pseudomonas aeruginosa, which under the right conditions can cause infections. This can be a particular concern in hospitals, where vulnerable people, more

likely to have a weakened immune system, could be exposed. Pseudomonas is a biofilm, or slime-producing bacteria, which, if left to proliferate can cause system fouling, leading to blockages and corrosion. Modern buildings are at a particular risk, fitted with smallbore pipework and control valves with small orifices. Build-up of the biofilm can reduce water flow and provide the ideal habitat for other corrosion-inducing bacteria, causing pitting and leaking in pipework, which leads to reduced efficiency and greater chance of downtime. To prevent the build-up of Pseudomonas and bacteria in general, it is essential that water systems are designed correctly, with ongoing monitoring and bespoke maintenance programmes. While there are standards in place to prevent bacterial contamination, in our view they don’t always go far enough. All too often water hygiene

is an afterthought, approached in a one-size-fits-all manner, usually consisting of an over-reliance on chemicals.

System design When designing a water system, hygiene must be considered from the outset, including how it will be used long term. While allowing for future expansion may be necessary, dead legs and capped pipes should be avoided where possible to prevent stagnation. If unavoidable they must be flushed out regularly. Pre-commissioning cleaning is a standard requirement of all new closed water installations under the latest BSRIA guidelines. By making sure a water system is clean from the outset, unnecessary maintenance and repairs can be avoided. Pre-commissioning cleaning involves flushing the system through with bacteria-killing

chemicals. An over-reliance on chemicals, however, can in itself cause problems, with some products actually exacerbating corrosion. On the flip side, any chemical handling poses risks to the operatives that come into contact with them. It’s important the approach is fit for purpose and where possible non-chemical alternatives are explored. New technologies are available that can be particularly effective as gatekeepers when a water system is installed, such as by harnessing a specific frequency of light and photocatalytic surfaces to create free radicals that break down harmful micro-organisms. Our version, Wallenius AOT, is extremely low energy and allows buildings to cut down their reliance on dosing. Ongoing maintenance and treatment is essential for ensuring HVAC efficiency. Water systems that use chemicals should be

monitored so that dosing is based on specific requirements rather than just adding more chemicals, regardless of the condition of the water. Eradicating Pseudomonas from our HVAC systems should be a priority, and to do this we need a total approach to water hygiene starting from the building’s design. The temptation can be to simply meet the regulations, with little thought as to how a water system will be used long-term. Initial money-saving measures, however, may cost further down the line, compromising efficiency and causing unnecessary maintenance call outs and breakdowns. PHAM NEWS ENQUIRY No.

52 PRODUCT Spotlight

A pick and mix heating solution There is a growing trend towards using more than one type of heat emitter in a single project. Andrew Lowery, Marketing Manager for Myson UK, looks at the principles of choosing the right combination of heating products to create a tailored total solution.

efore starting any installation, it’s important to consider the property as a whole – the size of rooms, available wall space, whether walls are interior or exterior, ceiling height, the number of doors and windows, levels of insulation and the building materials used. Once you have collated all this information, you should perform a heat loss Andrew Lowery, Marketing calculation, which can now be Manager at Myson UK done online, using resources like the Myson Heat Loss Calculator. In some buildings there will be special considerations. In hospitals or care homes, for example, you will need to use low surface temperature radiators (LSTs) to guard against accidental scalding of vulnerable end users and to comply with NHS Estates Health Guidelines. LSTs are also useful in settings such as retirement accommodation, special needs schools and children’s nurseries. Where end users have physical disabilities, adapted products can be specified, including dexterity TRVs for those with poor manual strength, and braille controls for the visually impaired.

Designer appeal Where aesthetics are particularly important, designer radiators will be a great option. Flat fronted panel radiators, such as our Plan Compact range, are currently very popular in corporate offices, executive homes or exclusive hotels. These add a great deal more style and subtlety, with the smooth flat panel option blending into minimalist décor, while the delicately lined front panel version adds flair and focus. Flat panels are also a favourite with facilities managers, as the smooth front panel makes them easy to keep clean, helping to maintain a pristine built environment for longer. In retail applications it is vital to maximise and monetise the available space. High level, wall-mounted fan convectors allow the space above doorways to be used for heating, freeing up walls for extra display space in shops and showrooms, for example, or additional tables in restaurants. Tall, vertical radiator styles are also increasingly popular as they add elegance while providing large heat outputs, while making clever use of wall space.

The Myson Floortec system installed in a domestic kitchen

In high-end private homes or exclusive galleries and exhibition spaces, sculpturally stylish designer radiator styles add elegance as well as space. In some settings, however, it is desirable for the heat emitter to be completely hidden, making underfloor heating the most practical solution. At Myson, we respond to many requests for help with system design and in around 30% of the resulting The Myson LST Slim with TRV installations the best solution now involves more than one type of heat emitter. A large proportion of these involve using hydronic underfloor heating with radiators. Many commercial buildings have a mixture of larger, more open spaces, often on the ground floor, with smaller rooms such as individual offices or hotel bedrooms, many of which will be on upper floors. In foyers and reception areas, open plan offices, restaurants or libraries, underfloor heating, with its ability to heat evenly and maintain a steady, energyefficient warmth, is increasingly popular, while in the smaller rooms radiators are often preferred for their rapid response times and the ease with which the temperature can be adjusted to suit the individual end user.

Mix and match Installers are increasingly using several heat emitter types together with great success – underfloor heating with radiators, radiators with towel warmers, electric underfloor with towel warmers, radiators with fan heaters – any combination that will best serve the property. If you are going to combine products, however, it is essential to create a whole system, so you must understand the benefits of each type and how they can complement each other. This can help you to decide whether to replace like for like in a renovation, for example, or whether to think differently and adopt a new approach. Understanding the heat output requirements for each space and viewing the entire project as a whole is so important. It allows us to start with a clean sheet every time, whether the property is new or established. Of course, no matter which heating products you choose, you must also include the appropriate valves and controls in order to ensure overall system efficiency.

The Myson Plan Compact radiator adds a touch of style

Myson’s wall-mounted fan convector (above) and Kickspace heater (below) can provide a space-saving heating solution

Source of heat The heat source must always be an important factor in determining the ideal combination of products, especially if you are using renewable technology such as a heat pump, but some of our preconceived ideas about heat emitters can now be challenged. Panel radiators, for example, are now an equally viable option with lower system temperatures, thanks to their lower water content and higher surface area, which allows us to obtain the same kind of outputs from relatively compact sizes. This makes them just as good an option as underfloor heating in many projects. When creating a total solution, you need to know that it will be exactly that. If you are using a combination of products, it is essential that they work well together and that you maintain quality throughout. A sure way of achieving this is to specify products from the same manufacturer, who has developed the products, knows how they work and, most importantly, can give unbiased advice on which combination will work best in each case. Products from the same manufacturer will have been developed to work together, whereas shopping around gives no guarantees of how the different parts of the system will perform. This is especially true when specifying an underfloor heating system. Sourcing individual underfloor heating components from a variety of manufacturers literally brings no guarantee that they will work efficiently together, whereas specifying underfloor heating products entirely from the Myson Floortec range, for example, brings with it the peace of mind of a system guarantee. Installing the system also needs to be planned for a time efficient installation on site, so a single source is a good idea for supply chain reasons too. The aim is usually to deliver lower energy bills to the end users, and all systems need to be well controlled. It is wise, therefore, to select a manufacturer that can also provide a full range of valves and controls, as well as heat emitters, and can also advise how best to control the system for maximum efficiency. If the same manufacturer can provide all the heating products and controls, they will also be best placed to offer advice and expertise – and you will only have one number to call to access their customer support. www.myson.co.uk

VENTILATIon & Heat Recovery 55

How to avoid installation errors The demand for mechanical ventilation with heat recovery systems is increasing, but so too are the number of installation errors. Here, Ru Kazlauciunas, Senior Technical Advisor at Zehnder Group UK, offers advice on how to avoid some of the common pitfalls.

Increased separation this isn’t always happening.

At solid fuel chimney terminal. Zehnder we’re actively helping to ensure that MVHR is properly understood, designed, and installed. To that end, Ducting layout we’re publishing a series of free eBooks on MVHR and Airflow resistance should be reduced by routing ductwork here we share some of the invaluable advice they contain. as directly as possible with the minimum number of bends. The ducting system ideally should be radial, not branched. The property A traditional branched ducting layout – with supply air MVHR is for airtight buildings only. It’s really only suitable from the MVHR unit feeding the building via one leg of for dwellings with air permeability levels of 5m3/hr/m2@50Pa ducting with branches off it and extracted air travelling and certainly for properties below 3m3/hr/m2@50Pa, and down another leg of ducting and on through its branches that means well-insulated new-builds. – is vulnerable to an over-supply or under-supply of air within each room.

Just because a particular unit has the airflow capacity on paper doesn’t mean it will be fit for purpose, especially if it has to run at 90% capacity all of the time. When designing, it is recommended systems are sized to operate at their optimal level to ensure the specific fan power is in line with industry good practice levels of 1.5W/l/s. This figure can change dependent on the air distribution and unit selected, however typically running at 60% or below and reducing system pressure drop should help meet this criteria.

Places to avoid Noise can also be needlessly generated by an inappropriately located heat recovery unit. Sites to consider are the plant room, utility room, hallway cupboard, recessed ceiling mounting, or basement. Places to avoid are bedrooms, garages, loft space, or outside. The client might have a preferred location, but it’s important to keep it within these parameters. In addition to this, the unit must be located to ensure easy access for servicing and maintenance.

Air valves The type of air valve should be located for its function and location. Is it to supply or extract air? Will it be positioned in a wall or a ceiling, and could there be tall furniture in that part of the room or beds and seating areas subjected to unwanted draughts? To create cross-ventilation within a room, best practice recommends low velocity air valves

Insulate ductwork

Where ducts pass through spaces outside the thermal envelope, such as a roof void, or when ductwork carries cold air through spaces within insulated parts of the home, ductwork needs to be insulated to reduce the risk of condensation forming. It’s also necessary to ensure that any condensate that forms within the duct can drain to a suitable outfall. Condensate drains should also be insulated where required to prevent freezing, and MVHR systems should be fitted with automatic frost protection.

Commissioning The aim of commissioning is to get the MVHR unit meeting the design airflow requirements on the lowest possible setting. The lower the setting, the quieter and more energy efficient the system will be. Poor commissioning can result in insufficient or excessive ventilation rates and an unbalanced system which fails to match the volumes of air being extracted from the building with the volumes of air being supplied. With over-ventilation, the unit will run at a higher speed and use more energy than necessary. With under-ventilation, indoor quality will deteriorate, increasing the risk of condensation and mould in wet rooms such as kitchens and bathrooms. It is not enough simply to leave the system at the factory settings as it may have to work too hard to overcome pressure from ducting and installation, resulting in unnecessary noise. Five essential checks should be made:

The Zehnder ComfoAir Q MVHR system is available in three sizes (350, 450 and 600m3/h) and is easy access for cleaning

1. Visual inspections: Check that the system is installed as per the design and that the ductwork and terminals are in good condition. 2. Start-up the system: Check that the airflow at each terminal and grille is in the right direction. Also check that the system is not abnormally noisy when startingup or running. 3. Measure the airflow: Airflow measurements should be made with all windows and external doors closed, using a calibrated measuring device with a proprietary hood attachment. 4. Balance the airflow: If necessary, attain the desired flow rate by adjusting valves at the terminals. In some systems, it may also be necessary to adjust the fan speed or duct damper (refer to the manufacturer’s guide). For domestic compliance, and in accordance with Part F of the Building Regulations, the actual airflow rate (in litres per second) and the design airflow rate at each room terminal should be recorded on a commissioning sheet. 5. Check the controls: Check that all controls have been installed in accordance with manufacturer instructions, that the function of all controls is clearly labelled, and check where possible that they function as they should. If the fan is automated, check that controls are set to minimise ‘hunting’.

Customer handover The Building Regulations for England and Wales state that sufficient information about a ventilation system and its maintenance requirements must be provided to owners or occupiers at handover. They itemise exactly what must be explained and demonstrated, and what information must be left with the end user. At Zehnder we publish a user manual for each of our MVHR systems, accessible from our website, and it is recommend this should also be provided to the end user. For more information about MVHR commissioning, handover and maintenance, Zehnder has published a series of free eBooks for specifiers, designers and installers, all downloadable at the website below. www.zehnder.co.uk

Control in multi-occupancy buildings Commission and control MVHR The Duplexvent range of commercial mechanical ventilation with heat recovery units from Airflow now includes variable air volume (VAV) dampers. The VAV systems constantly monitor the air volume supplied and share this information with the ventilation unit. As such, the systems ensure optimum air quality and comfort by allowing the ventilation to respond effectively to the demands of each area of the building. Variable Air Volume (VAV) dampers offer a solution to issues around multioccupancy in buildings because they control the flow of air to each zone of the building in response to changes in demand. This helps to maintain a consistently high quality indoor air

environment. The VAV dampers fitted to the Duplexvent range constantly monitor the air volume passing through the system and send this information to the centralised ventilation unit. The communication between each

damper and the central unit allows the MVHR system to increase or decrease the flow rate quickly and efficiently based on the demand. When used in conjunction with humidity or CO2 sensors, these dampers can automatically adjust the ventilation based on the usage or occupancy of that room, independent of the other areas within the building. Airflow’s VAV system also provides the option of manual adjustment for applications where the user requires a level of control. The VAV dampers system ensures that Airflow’s MVHR units can respond swiftly and effectively to changes in demand. PHAM NEWS ENQUIRY No.

Looking to improve all aspects of the bathroom fan, National Ventilation has developed the Monsoon Zone 1 Energysaver Fan Kit to deliver near-silent operation and high efficiency with an aerodynamic mixed-flow impeller. The kit comprises three parts: the Monsoon Zone 1 Silence Fan, a non-cut semi-rigid wall sleeve, and the Energysaver Grille. The fan is said to deliver silent operation and high efficiency with an aerodynamic mixed flow impeller. With the benefit of being IP45, this means the fan can be mounted in zone 1 without a 12V transformer, giving greater flexibility when it comes to siting. The wall installation kit provides 20% less resistance than standard grilles or cowls. The kit also contains the Monsoon Energysaver Grille, a new cowl designed to counteract the adverse effects of external wind on the performance of the mechanical extract ventilation systems.

LPG Heating 61

Compelling reasons to make the switch Although oil is more prevalent in off-the-gas-grid homes, there are many good reasons to make the switch to LPG heating. Here, Gregor Dalgleish, National Sales Manager at Calor, discusses why installers should consider the advantages this market presents.

or installers used to working on houses connected to mains gas, it can sometimes be easy to forget the almost four million homes out there unable to connect to the gas grid. At the moment most of these properties are fitted with oil-fired boilers, which have long been treated as the ‘standard’ off-grid heating solution. Many homeowners will have inherited their heating system when they bought the house and may not even be aware that there are alternatives such as LPG, which could provide substantial user benefits. Whether it’s a new build, a refurbishment or a simple replacement, there are several unique issues that need to be considered around choosing a fuel source when working on an off-grid home. For a start, remember that the homeowners will effectively have to store all their own fuel on-site and ensure they always have enough to run their heating and hot water systems.

Fuel handling

LPG fuel can be discretely stored out of sight underground

Fitting an LPG boiler is similar to a traditional gas boiler

It’s easy to see how this can prove a headache for the homeowner, who has to make sure they keep on top of their fuel supplies and is stuck with a large – often rather unsightly – tank or storage shed somewhere in their garden. With LPG, however, it’s simple to eliminate these problems almost entirely. If the homeowner can choose to have an underground tank, with the only evidence of their presence being a small access hatch. At the same time, Calor’s automatic top-up telemetry can let the gas supplier know when the tank is running low and arrange a re-fill without any work for the customer. Another benefit that’s easy to overlook is how secure LPG is. This may seem minor, fuel theft is among the leading rural crimes, and having an oil tank drained by thieves can be a highly upsetting – not to mention expensive – experience. LPG, however, is virtually impossible to steal. Anyone attempting it would need highly specialised equipment, and as far as we know there has never been a case of thieves successfully siphoning off LPG from a UK home. Of course, the benefits provided by LPG reach much further than the storage options. As far as the homeowner is concerned, it offers all the practical comforts of mains gas, providing everything from heating and hot water to gas fires and a real flame for cooking.

This not only makes it incredibly versatile, but also instantly familiar to homeowners used to living on-grid. This can be a real bonus, especially as statistics show an increasing amount of people are moving from major urban centres to rural areas. These former city-dwellers will be used to the convenient and hassle-free home heating solution offered by gas, and may appreciate being able to nearly replicate the experience in their new home.

customers retain their existing oil or solid fuel system out of convenience, rather than choice. However, an LPG system can be installed quicker than many installers may assume, with a range of storage options, from an aboveground tank, underground tank or cylinders. Some LPG suppliers will also work with installers to help specify and coordinate an installation. Calor, for example, provides a local expert that will organise tank siting, external pipework and connecting the gas to the property, leaving the installer to concentrate on the boiler installation and/or any internal upgrades. For those installers that are equipped with the right training and certification, an LPG installation will be very similar to fitting a traditional gas combi boiler, saving time on the job compared to the potential complexities of an oil boiler install. LPG boilers are also highly energy efficient, with many ‘A’ rated options on the market from well-known manufacturers to choose from. Where an existing oil boiler is nearing 10 years old, it’s likely to be less efficient, while investing in an LPG boiler is on average £900 cheaper than buying a new or replacement oil boiler. In addition, LPG installation costs are reduced further as the customer does not have to buy the tank. Unlike oil installations, where the tank can cost as much as £2000, most LPG suppliers, for a small fee, retain ownership of the tank and remain responsible for its maintenance and upkeep.

Going green At the same time, many people are also choosing to focus on the environmental aspect of their house. Once again LPG has several advantages in this area, as it’s the greenest fossil fuel available to non-mains gas homes, emitting around 20% less CO2 per kWh than heating oil. With all these advantages for LPG, it may seem odd that oil is still the most common choice of fuel for offgrid homes. One of the big reasons for this is that when it comes to installing a new boiler, replacing the heating system on a like-for-like basis can often seem the easiest – and therefore the default – route. There are also several common misconceptions out there, such as the belief that switching fuel supply will result in significant upheaval and cost. This can mean

Tumble dryers turn over the business LPG tumble dryers could present rural installers with a new stream of business according to Calor. Recent research has found that LPG tumble dryers cost around 25% less to run than standard electric dryers, making them a choice for the 2 million UK homes that are off the mains gas grid. In recommending the switch to LPG home heating from alternatives such as electricity, oil, or solid fuel, installers can benefit from the additional work

alongside this conversion, such as fitting a new LPG boiler and tumble dryer – as well as other LPG appliances such as fires and cookers. LPG tumble dryers use the gas to heat the air inside the dryers, which in turn dries the laundry. They still use a small amount of electricity to turn the drum and power the control panel, but this is less than 10% of the total electricity used by a standard electric dryer. As well as being cheaper to run, LPG models are

more energy efficient too. Calor’s LPG dryers have an energy rating of ‘A’, whereas regular electric dryers most commonly have an energy rating of ‘C’. This means they can be more than 40% more energy-efficient than electric dryers. Gas tumble dryers also help reduce build-up of static in fabrics, which can damage clothes, and a reverse tumble action means that items are less likely to become tangled and creased.

Calor’s LPG dryers can be fuelled by gas from bottles, or from a larger storage tank if LPG is already used for home heating. Teresa Wafer, Appliance Manager at Calor, says: “Installers should look to arm themselves with these statistics about the cost and energy saving benefits of LPG tumble dryers, and inform their off-grid customers about these benefits in order to gain new LPG installation work.”

Incentive to specify Calor’s Installer Incentive Scheme offers £250 for each new tank customer referral or £100 for a new cylinder customer. What’s more, we are currently offering a free tank installation to new customers, making the installer’s job of recommending the switch to LPG easier and initial costs cheaper for the customer. Homeowners can receive an above ground tank installation free of charge – this includes tank delivery, installation, civil works and the gas connection. We have also recently launched a ‘Find an Installer’ tool on its website, a new function that allows homeowners to search for an LPG-qualified heating installer. The Find An Installer tool has been created to make it easier for customers to connect with local LPG installers. Being included on the Finder means installers can be contacted directly by homeowners currently using LPG for their heating, or those interested in switching to Calor LPG. www.calor.co.uk/installer

62 LPG Heating

Big fuel savings for luxury hotel LPG supplier Flogas has helped a Cheshire hotel to switch from oil to LPG and achieve a significant saving in energy costs. The Carden Park Hotel, a Green Tourism Gold Award holder, is undergoing a major refurbishment and has had 10 LPG tanks fitted underground.

n a move to cut costs, carbon and enhance efficiencies, Carden Park Hotel in Cheshire has switched its entire energy supply from oil to LPG from Flogas. The conversion has seen the hotel reduce its energy costs by 21.8%, whilst reducing carbon emissions by 23%. Set within a picturesque 1000-acre estate, the off-grid hotel boasts 196 rooms, 18 meeting rooms, a luxury spa, two championship golf courses, two restaurants and 10 wedding ceremony venues, not to mention a three-acre vineyard – one of the most successful in the North of England. With more than 20,000 guests visiting Carden Park each year, a significant amount of energy is needed to power its heating, hot water and cooking facilities – so it was vital for the hotel to find a reliable, cost-effective and efficient energy solution.

High demand Carden Park’s General Manager Hamish Ferguson says: “With such a high energy demand, we were spending a fortune on oil so we were particularly keen to find a way to reduce overheads while lessening our impact on the environment. We researched other off-grid options, such as renewables, but LPG just made total sense for us. Not

only did it provide the quickest payback period, but we’re now saving 277 tonnes of carbon each year in the process – a key reason we continue to be a Green Tourism Gold Award holder. The switch to LPG has also meant we’ve been able to reduce our system maintenance, resulting in even further savings and minimal disruption.” Flogas managed the conversion and fitted 10 LPG tanks discreetly underground in the vineyard to ensure they didn’t impact the landscape for guests and visitors. The hotel now receives an LPG delivery once a week, although inbuilt telemetry systems on the tanks automatically monitor volumes and alert Flogas when refills are needed. “Reliability is everything when it comes to our fuel supply,” says Hamish. “LPG is literally at the heart of the hotel and without it, the business would be completely scuppered. Not only do the telemetry systems automatically ensure we never run out of fuel, but the local Flogas plant in Wrexham means we have complete security of supply.” Carden Park became an independent hotel in 2014 and is

currently undergoing a major £4m refurbishment, which will be completed in early 2017. This includes a full revamp of all bedrooms and suites, conference rooms, the main bar and lounge, spa and Cheshire golf course.

Savings plan Neville Scott, Flogas National Business Development Manager, adds: “Carden Park Hotel is a great example of how a straightforward switch from oil to LPG can make a major difference on operations. As a particularly large site, planning was integral for this project, with 420m of groundwork to consider. However, Flogas worked closely with Hamish and team from start to finish to ensure that the switch was as seamless as possible. Now, the on-going savings simply speak for themselves, and Carden Park is enjoying a cost-effective, efficient, low maintenance and reliable supply.” www.flogas.co.uk

Saving on carbon emissions High output condensing boiler Available from Rinnai is a range of LPG condensing hot water heater units that are said to be ideal for use in off-grid installations. According to the company, a continuous flow water heater will enable the end user to reduce energy costs by up to 50% and reduce greenhouse gas emissions by up to 61% (compared to electric equivalents). When compared with oilfired systems this saving is even greater. A Rinnai condensing water heater emits approximately 10% of the NOx that an oil boiler emits, a 90% reduction. The water heaters are already compliant with EU proposals to reduce maximum NOx levels to just 56mg/kWh by 2018. A Rinnai LPG continuous flow water heater is an ‘on-

demand’ system. When a hot-water tap is opened, the unit reads the demand and starts the heating process. The water flows through a heat exchanger, where it heats to the desired

temperature using only as much gas as is needed. When the tap is turned off, the heater automatically shuts off. PHAM NEWS ENQUIRY No.

The floor standing Varmax boiler is the latest addition to the stainless steel range from Hamworthy Heating. The powerful condensing boiler is fully ErP compliant and is designed for demanding applications with high output requirements. The boiler’s long term reliability is ensured by fully welded stainless steel heat exchangers that are less prone to corrosion caused by poor system water quality. An internal circulation pump with non-return valve provides even heat distribution at low system flow rates, simplifying installation with no need for a low loss header or dedicated primary circuit, while an internal combustion non-return flap makes the boiler easy to install in cascade flue arrangements. Easy servicing and com-

missioning of the boiler is made possible thanks to a reversible control panel, along with quickly removable door panels and access doors to all important components. Maximum water pressure of 6 bar and LPG compatibility make the Varmax suitable

for off-grid locations seeking more efficient and cleaner heating sources than oil, with low environmental impact (rated NOx Class 6 with < 40mg/kWh). It comes with a five year warranty on the heat exchanger and is available in eight single (120 to 450kW) and four dual (550 to 900kW) models. Product Manager Trevor Struck says: “We recognised the need for higher outputs and greater energy efficiency in many projects, such as district heating schemes operating with wide differential temperature. Twin return connections accommodate split temperature heating systems, allowing greater opportunity for the boiler to condense, improving system operating efficiency.” PHAM NEWS ENQUIRY No.

Taps & Washrooms 65

Taking advantage of non-touch technology Infrared technology offers an effective way to both improve hygiene standards and cut utility bills. Chris Tranter, Specification Product Manager at Bristan, argues that it should be an important part of the armoury of any installer looking to branch into commercial work.

he good news is that, following a hiatus either side of the EU referendum, UK construction activity recovered this summer. According to the latest reports, the Markit/ CIPS UK Construction Purchasing Manager’s Index (PMI) rose to 49.2% in August from 45.9% in July – a figure much higher than widely predicted – with the commercial market continuing to hold its own. Of course, new commercial Chris Tranter from Bristan buildings require washrooms, and the general uplift in the economy could also be encouraging the owners and managers of existing buildings to upgrade outdated washroom facilities. Therefore, it can be easy to see why traditional plumbing installers may choose to branch into the commercial field and capitalise on these opportunities. It is important to remember though that commercial and public sector buildings have very different requirements to domestic properties – and these will vary from application to application. For some projects, washroom products that reduce the spread of germs and bacteria or lower water usage will be important. For others, accessibility in line with Part M of the Building Regulations (Access to and Use of Buildings) or trouble-free maintenance could be crucial factors. However, one product category which boasts numerous benefits and is therefore sure to meet the demand of most applications is infrared technology. First and foremost,

technology detects human contact and automatically flushes the individual urinal after use, thus alleviating the need for human contact. Plus, the direct flush removes the need for an auto-flush cistern and associated plumbing used in traditional installations, which flush all urinals intermittently. And again there is a major added bonus to using both of these technologies – efficiency. With traditional setups, taps may be left running, or simply drip, while cisterns may have an unnecessarily high water demand, but nontouch technology means water is only used as needed. This enables buildings to significantly minimise mains water use in order to lower their environmental impact and cut water bills.

Soap saving Infrared technology means a tap is never left running

infrared washroom products can drastically improve hygiene measures. An integral infrared sensor will automatically detect movement and turn the water on/off, as required, eliminating the risk of germs being spread via the hands. Secondly, these devices can make for major water savings by ensuring water is only used as required and also preventing devices being left running when not in use.

Switched on In terms of what to recommend, an infrared tap range is a no-brainer. Infrared technology will detect human presence and switch on the water flow, delivering the right amount of water when required. In this way, the non-touch mechanism alleviates the risk of germs spreading, making it ideal for use in all premises seeking to optimise hygiene levels – all while eliminating water waste too. Another solid recommendation is a urinal infrared automatic flush. Working in a similar way, the infrared

But the considerations don’t quite end there, with the recent introduction of a new infrared soap dispenser specifically created to aid infection control in premises where hygiene needs to be at the highest possible level. In a similar vein to water-related infrared products, the dispenser spout incorporates infrared technology to detect human presence and dispenses a user-set volume of soap thus avoiding the risk of cross-contamination between hands. In addition wastage is eliminated, further helping with efficiency measures. The importance of infrared washroom technology in the commercial environment cannot be underestimated. Not only can it drastically reduce the risk of cross contamination, aiding infection control measures – but it can also help to eliminate wastage, leading to cost reductions. Therefore, for the domestic installer who is looking to diversify into commercial installations, it’s one technology to surely take stock of. PHAM NEWS ENQUIRY No. www.specifybristan.com 144

Point of use heaters get an upgrade Easy way to check water consumption

The FBM point of use water heater from Heatrae Sadia had been upgraded to offer improved levels of energy efficiency, greater defence against legionella, and the incorporation of Building Management System (BMS) technology. Said to be ideal for applications such as washrooms and commercial kitchens, the FBM Eco can supply between two and eight basins, dependent on the model selected. Permanently plumbed and generally sited next to the point it serves, the water heater is fed directly from the cold water mains. The unit can also be monitored and controlled remotely, which means any faults can quickly be detected and rectified.

Additionally, the FBM Eco features a new Legionella Control System (LCS) which pasteurises the water every 24 hours if the temperature falls below a certain level. Heatrae Sadia has also launched an updated version of its R Unit vented storage water heater (pictured above

right). Like the FBM Eco, the new R Plus is not cistern fed but uses a solenoid for easier maintenance. It also incorporates the Legionella Control System along with a higher efficiency rating. To make installation as simple as possible, both the FBM Eco and the R Plus

feature universal bracketing. This ensures that installs and retrofits are quick and easy, with no drill holes necessary and minimal need for any remedial work. Richard Newman, Senior Product Manager at Heatrae Sadia, says: “The FBM Eco builds on all of the best features of the FBM range and adds a new layer of functionality and safety. “Similarly, we have upgraded the R Unit to offer greater safety, better performance and intelligent fault reporting.” The FBM Eco and R Plus ranges are both available in four sizes: 25, 45, 70 and 120 litres, all backed by a five year guarantee.

the cascade frame and wall bracket are easier to assemble. The new frame can accommodate the 49, 60, 80 and 99kW models of the Vitodens 200-W range, while the 125 and 150kW models will continue to use the

previous frame. A new, fully pre-assembled heating circuit connection set also helps to make the system more compact and faster to install. The connection set brings together the circulation pump, check valves, integrated ball cocks, and distribution manifold. Marketing Director Darren McMahon comments: “The range of outputs for the Vitodens 200-W boiler mean it is ideally suited to any application, domestic or commercial, but when a number are combined they’re also perfectly capable of satisfying large commercial heating load applications.” PHAM NEWS ENQUIRY No.

WHat’s New Electric hot water heating made easy Electrically heated homes will benefit from Dimplex’s latest addition to its Quantum range of intelligent hot water cylinders. Combining easy to use controls with a slimmer design, the new QWCd135480 (135 litre) and QWCd180-480 (180 litre) models are suited for social housing properties and those where space is limited. The Quantum electric cylinders use off-peak electricity to deliver cost-effective hot water, working directly from the mains water supply to ensure mains pressure from all outlets in the home. Controls enable better planning of water usage by showing users how much hot water is available to use. With the latest in electric heating technology and heat retention capability, they also ensure that the correct amount of water is stored to accommodate the needs of the household, whilst using the minimum amount of energy. All models are available as part of the Dimplex Quantum heating system together with the company’s Quantum off-peak heaters, or operated as a standalone hot water system for electrically heated homes. www.dimplex.co.uk/quantum
