CPD – CONSULTATION; THE KEY TO BOILER SELECTION

January/February 2017

“theory alone is useless” “practical alone is dangerous” Imagine your customer complaining about excessive noise within the heating system that you have just fitted, or the radiators or underfloor heating are not delivering enough heat to the For plumbing & heating room. Well it could actually be down to engineering professionals incorrectly sized pipework! “Why is this?” Pipework, fittings and other ancillary equipment that are fitted within a system create a resistance to the flow of water, which in turn creates a pressure loss through friction. Dependant upon the amount of flow required to deliver a specific amount of heat, the correct selection and design of pipework is critical to ensure that the heat emitter (e.g a radiator or floor heating system) is supplied the correct volumetric flow of heated water. In addition to the effect on the delivery of heat, incorrect or undersized pipework can lead to excessive flow velocities which in turn creates noise. These high velocities can also cause cavitation at elbows, pumps and valves, which can ultimately lead to the system failure.

The amount of volumetric flow rate required to deliver a specific amount of heat is calculated using the simple formula (1) .

Question Calculate the required volumetric flow rate based upon the following system parameters; (1) 18 kW heat load (2) Specific heat capacity of water 4.19 kJ/kg.K (3) Temperature difference of 10 o C. (4) Density of water 0.977 kg/m3.

Answer 0.44 l/sec =

18 (4.19 * 0.977 * 10)

Tip When designing a heating pipe system, the plumbing and heating engineer must design the pipework to ensure water velocities do not exceed recommended levels. Pipe Diameter (mm) 15 - 50

Velocity (m/s) 0.75 - 1.15

A starting point could also be to limit the pressure loss per metre of pipe

to between 250 to 350 Pa m. However, you must understand the theory before making such assumptions Pipe sizing is an easy process when you know how, although it is important to understand some simple housekeeping rules. Before you calculate the pipe flow velocity, it is important to ask the manufacturer for the “internal” diameter of their pipework.

MESSAGE FROM THE CEO

EXCITING CIPHE PROJECTS FOR 2017

Proud to be a Professional The CIPHE has been on a mission to champion the efforts of plumbing and heating engineers across the UK. Kevin Wellman, CIPHE CEO kevinw@chipe.org.uk

his time last year, the Institute launched the ‘Proud to be a Professional’ campaign, aimed at highlighting the essential services that plumbing and heating engineers provide for the general public. It has also served to encourage fully qualified installers to take pride in the work they carry out daily. My thanks go to the trade press who have provided excellent support through their magazines by publicising CIPHE activities. Over the past 12 months, we have introduced a variety of initiatives that support our objectives, with an overview of the success charted here:

TECHTALK Paul Harmer, CIPHE Technical Director, has been working on a series of webinars, which are open to both members and non-members of the Institute and participation is free. This strengthens our commitment to collaborate with representatives from the wider industry in order to deliver the most up-to-date and worthwhile CPD experiences possible. With the aim of raising awareness and explaining various technical topics, the Institute has introduced ‘techtalk live’, with our most recent webinar exploring the topic ‘A realistic approach to saving carbon’ in conjunction with the Worcester, Bosch Group. This video received over 3,500 views in its first week, which is a strong indication there is a real appetite for this type of

4_ceo.indd 4

journal

accessible, online learning. We have also launched ‘techtalk – the apprentice’, which sees the CIPHE go on the road to film a day in the life of an apprentice.

SMARTTALK Alongside this educational webinar series, we have developed ‘smarttalk’; which focuses on the vital soft skills that plumbing and heating engineers require. Topics cover three key areas – legal, finance and marketing, with the first ‘smarttalk’ addressing good business practice. This will explore the Consumer Rights Act and how it affects the industry in their day-to-day roles and responsibilities, to help protect both the installer and the consumer. At the year end we launched an extremely competitive range of insurance services which will be advantageous to those of you involved in running plumbing and heating businesses. (See page 10 of this issue.) Watch this space for more news of additional and exciting new membership services in the months ahead.

INCREASED SUPPORT A huge amount of work has also taken place during 2016 to re-engage with Industrial Associate (IA) members and encourage participation in events like the quarterly IA Development Group meetings to ensure everyone’s voice is heard. As an Institute, we are particularly keen to highlight

how leading manufacturing brands and merchants can help shape the future of the plumbing, bathroom and heating industries. Our discussions have centred on the role that IA members have to play in supporting the CIPHE to raise the industry’s profile and encouraging the need for quality products to be designed and installed by quality professionals. It’s been refreshing to see the number of representatives from IA members in attendance at our meetings and I look forward to meeting many more new faces in 2017.

VOLUNTEERS The CIPHE has been fortunate to receive immense support from volunteers including Trustees, Branch supporters, Committee Representatives, Professional Standards Inspectors, Membership Ambassadors, Marketing and Communications Group supporters and all those involved in our technical activities. My immense thanks and appreciation go to you all. The CIPHE has had a substantial increase in membership enquiries in recent weeks, from both individuals and companies who are employing plumbing and heating professionals. This has put the Institute in good stead for 2017, as we embark on a sustained membership drive. We anticipate a busy and successful year ahead and I look forward to your continued support throughout the year.

ALL THAT’S HAPPENING IN THE PLUMBING & HEATING WORLD

TALENTED APPRENTICE IS BEST IN REGION A talented apprentice has beaten hundreds of others to be recognised as the best plumber in the North East. Daniel Gowland, an apprentice at Mears and Gateshead College, has been recognised by the Newcastle Branch of the CIPHE for his hard work and expertise in his field. The prestigious JB Wilkinson Shield, which was established in 1913 by the Master of The Worshipful Company of Plumbers, recognises outstanding apprentices as well as outstanding teaching. Both Daniel and Gateshead College were presented with the two-part award by Erica Stary, current Master of The Worshipful Company of Plumbers, which works closely with the CIPHE. Daniel who is 27 and from Gateshead, said: “I have always wanted to be a plumber

after watching my dad work in the industry. He would teach me how to do certain tasks when I was young and I always really admired the work he did. Now, thanks to Gateshead College and Mears, I can work in a job that I enjoy while training to qualify. “The award is also a fantastic accolade to put on my CV as well as a great confidence boost. It was a surprise to hear I had won. My college tutor put me forward so it was really assuring to know that they believe in me and that I have great support from them.” The JB Wilkinson Shield is awarded following the assessment of the nominee’s portfolio, which includes written and photographic evidence of their work and understanding of plumbing and heating. Each regional branch, in this

case Newcastle, collects and assesses the information ahead of the regional awards. The JB Wilkinson Shield for the best plumbing college 2016 award marks the fourth Gateshead College student to collect the accolade in its 103 year history, with wins in 2014, 1936 and 1931.

2016 COLLEGES SCOTLAND PARLIAMENTARY RECEPTION

YVONNE GETS SHIRTY!

CIPHE Approved Training Centre, West College Scotland (WCS) took part in the 2016 Colleges Scotland Parliamentary Reception. The event themed, ‘Colleges − Delivering a Stronger Economy and a Fairer Society’ was hosted by MSP James Dornan at the Scottish Parliament in Edinburgh last September. Blair Martin (19), a first year apprentice plumber from Neilston Glasgow said: “I really enjoyed demonstrating the skills that we have gained in class. It’s not every day you get to go to Parliament and meet the Head of Education so I really enjoyed it.” Curriculum and Quality Leader for Engineering at the Colleges Greenock campus, Harry Hunter said: “I was extremely impressed with the enthusiastic manner that the apprentices engaged with the Scottish ministers. They are a credit to their companies and great ambassadors for the college. “The students were extremely proud to represent the college at such a prestigious event and took great pride in showcasing the wonderful work they have done.”

Shower designer and manufacturer, Roman, has presented Yvonne Orgill with a gift to celebrate her 30 years at the Bathroom Manufacturers Association (BMA). As a mark of Roman’s appreciation for Yvonne’s dedication and hard work, she was presented with the Welsh Rugby shirt signed by each current squad member. Outside the BMA, Orgill is a passionate supporter of Welsh Rugby, which makes it the perfect gift. David Osborne, Managing Director of Roman, commented: “We have greatly valued Yvonne’s support throughout the years and we wanted to show our appreciation by presenting her with a signed rugby shirt by her beloved Welsh Rugby team.”

‘ROADMAP’ FOR HEATING EFFICIENCY A new report issued by the Government’s official climate advisors has been welcomed. Neil Schofield, Head of Government and External Affairs at Worcester, Bosch Group – one of several stakeholders consulted as part of the report’s research – believes the Committee on Climate Change’s ‘Next steps to UK heat’ policy report offers clear direction for the heating industry to follow in its bid to green Britain’s heating supplies. Neil said: “We appear to have robust advice for the Government to follow which acknowledges that energy policy needs to be about more than simply switching the lights off. Heat represents 40 percent of the energy we consume and 20 percent of our greenhouse gas emissions, so it is pleasing to see the Committee on Climate Change produce such a welcome roadmap for heating efficiency. “By indicating that hydrogen could prove to be a sustainable long-term alternative to natural gas, the report effectively advises the

Government to stay faithful to our hugely successful and accessible gas grid, which has to be the most practical route towards our 2050 climate targets.” Neil goes on to stress his expectation that it is this decarbonisation of the grid at source – rather than the report’s other proposed Neil Schoﬁeld, Head option, the increased use of heat pumps – that of Government and will have the greatest impact on greening UK External Affairs heating supplies. at Worcester, Bosch Group “The new ministers in position at the Department for Business, Energy and Industrial Strategy (BEIS) have a fantastic opportunity to drive these recommendations forward. All we need from them now is the political will to make a real difference.”

5 REASONS

CIPHE MEMBER INVESTS IN STAFF TRAINING CIPHE Industrial Associate member, Salamander Pumps is (L-R) Gareth Richards, Lewis Wilkes, Ken Vance, strengthening its commitment to customer service, innovation Stephanie Clark and and product development, with an in-house apprenticeship Jayson Shepherd programme that has seen its first student graduate into a permanent role, while seven of its staff are combining work with studying for qualifications. Salamander has appointed 22-year-old Jayson Shepherd as a Research and Development Engineer, following a successful three-year apprenticeship to complete his HNC in Mechanical Engineering and an NVQ level three in Engineering Technical Support. Stepping into Jayson’s shoes is Lewis Wilkes, who is studying for an HNC in Mechanical Engineering and becomes the company’s second full time apprentice. Gareth Richards, Technical Director at Salamander Pumps said: “We committed to an apprenticeship programme several years ago, to encourage young people into the industry and promote a ‘grow our own skills base’ culture. As an ex-apprentice, I have first-hand experience of the value of this method of kick-starting a career, and the opportunities it presents for young people and their employers.” As part of Salamander’s pledge to continuous training for its staff, seven members of the technical, administration and support teams are combining their roles with studying for a range of qualifications including manufacturing engineering, sales, business administration and contact centre operations. Among them are Marketing Assistant Stephanie Clark, who joined the company as a graduate intern in 2014, and ex-plumber Ken Vance who recently completed an HNC in Manufacturing Engineering.

CIPHE APPRENTICE AWARDS

CIPHE APPRENTICE Proud to be a Professional AWARDS 2017 The CIPHE is putting the spotlight on professionalism within the industry, with a view to attracting more school leavers to recognise the life-long career opportunities presented by apprenticeships in the sector.

o highlight the excellent work of young people who have already found their vocation in the plumbing and heating sector, the CIPHE launched its very own Apprentice Awards last year. The awards initiative aims to help raise the profile of apprenticeships by recognising both the technical and ‘soft’ skills of young people starting out in the trade.

CATEGORIES There are three categories in total, including an award for heating work, which is sponsored by the Heating and Hotwater Industry Council (HHIC), an award for plumbing, sponsored by the Bathroom Manufacturers Association (BMA) and an award for those apprentices who are able to demonstrate how they are protecting vulnerable people in society. The ‘vulnerability’ award is sponsored by the CIPHE and will recognise how young installers are able to make a difference to the health and wellbeing of the general public as a direct result of their work from a very early stage.

INTRODUCTION TO AIR ADMITTANCE VALVES (AAVs)

Steve White, Technical Director at Studor Ltd, says that although there is a growing awareness of the risks to health from the drainage system, it is often given little thought, despite it being one of the few building systems that is integrated throughout the whole building.

he water trap seal

is the only barrier between the drainage system and the living and/ or working space; it is therefore Steve White, Technical Director at essential that this Studor Ltd is maintained at all times. The loss of a trap seal results in unwanted smells, noise and, importantly, the risk of pathogens/disease spreading from the drainage system into the inhabited space. While these are unpleasant in a domestic environment, there are serious health and safety concerns in a commercial environment, where the building owners, landlords and/or occupiers have a duty of care.

WHAT AFFECTS WATER TRAP SEALS? Drainage venting is all about preventing the system pressure from exceeding -400 Pa (40mm Wg), i.e. the pressure at which water trap seals will be affected. This would be mostly due to pressure fluctuations (self siphonage, induced siphonage, positive pressure and wind effect) and thermal depletion. A negative pressure transient occurs when there is a discharge of the fixture to which the trap seal is connected. This can have the effect of reducing the trap seal (or pulling the trap). This occurs as the momentum acquired by the waste passes through the fixture and down the trap seal. This momentum is transferred directly into the trap seal and trap seal loss occurs (self siphonage). Other fixtures discharging in the building can also affect the trap seal. This occurs when there is a pressure fluctuation caused by a discharge of another fixture in the system, other than the fixture to which the trap is connected. This is known as ‘induced siphonage’, which is very common in multi-storey/multi-use buildings.

Defective water trap seal: RISKS HEALTH

KEY VENTING COMPONENTS OF A DRAINAGE SYSTEM 1. Trap venting: Venting of a single fixture. 2. Group venting: Venting of a group of fixtures, using one vent on the wet side of the last fixture. 3. Branch venting: Ventilating pipe connected

to a branch discharge pipe. 4. Stack venting: Extension of the vertical discharge pipe above the highest

AAVs work by utilising a reverse lift membrane. When there is water movement in the system, the valve will open; when the movement of water stops, the AAV will seal airtight by gravity. AAVs have the effect of slowing down pressure transients

Direction of air entrainment

branch discharge pipe connection that terminates at an end, open to atmosphere or with an AAV. 5. Ventilating stack: Main vertical ventilating pipe, connected to the discharge stack to limit pressure fluctuations within the discharge stack. 6. Drain venting: Venting near the end of a main drain or branch drain, the vent being installed on the wet-side of the last fixture. A combination of the above can be used on larger projects, but these methods have limitations, as open vents require penetrations through the roof, to allow the atmospheric air to balance the pressure transients within the sanitary drainage system. The larger or more complex the system, the longer it takes for the vent at the top of the building to react, leading to depletion of the water trap seals. You know when this occurs by just watching and listening. For example, if you see the water in the WC pulling, or listen to the P-trap gurgling, this is an indication venting is inadequate, as the traps are being pulled due to the pressure in the system. Alternatively, AAVs can be installed at the ‘point of need’ (PON), near the trap seals that require protection. This has the benefit of eliminating the vent pipe network, the space required and the roof penetrations.

WHAT IS AN AAV? An AAV is a valve that limits pressure fluctuations within the sanitary drainage system, by allowing air to enter the system, but not to escape. It draws the air, which is

in the building and providing air at the PON, eliminating the risk of pathogens leaving the sanitary drainage system and entering the living and/or working space. Most important is that the AAVs are sealed airtight when there is no movement of air in the system.

CRITICAL ASPECTS OF AN AAV’s OPERATION 1. The need to respond quickly to changes in pressure, every time. 2. The necessity to seal completely tight with no leakage whatsoever. 3. Longevity of operation (as long as the drainage system itself).

Discharging appliance increases entrained airﬂow and generates

negative transients Trap seal depletion

Mini-VentTM Local inwards relief airﬂow maintains trap seal

CHOOSING THE RIGHT AAV

Choosing the correct AAV is important. In the UK, AAVs must conform to BS EN 12380, they must display the correct information and the CE mark. To further ensure that the

AAV airﬂow reduces demand

required to maintain the trap seals, from the living space where it is installed. An AAV should open before -75 Pa, allowing air into the system and relieving the negative transient pressure. This keeps the pressures in the system for discharges

between 0 and -250 Pa. If the system goes above these pressures, this can lead to the depletion of the trap seals. A typical P-trap will suck dry in less than one second, if the pressure in the system reaches above -500 Pa (50mm Wg).

AAV is of verified appropriate quality, it is recommended that the valves also have a third party accreditation, for example, a BBA certificate or KEYMARK approval.

AAVs that utilise springs, O-rings or clip fit lids should be avoided, as these generally inevitably lead to leakage at low pressures. Under BS EN 12380, AAVs are rated for performance. An ‘A’ rated AAV can be installed up to one metre below the appliance’s flood level and a ‘I’ rated AAV has been proven to operate in extreme temperatures from -20°C to +60°C. Having an AAV that meets the ‘AI’ or the ‘AII’ classification will ensure the product is of sufficient quality and performance to provide full protection.

NATIONAL PRESIDENT

PRESIDENT’S DIARY

Proud to be a Professional

Paul Williams

Paul Williams, CIPHE National President, combines running his own business with his CIPHE duties, So this is a particularly busy time of year for him.

ver the last couple of months, I have had the pleasure in presenting awards to members at both ends of their careers. First there was the Wilkinson Shield, which itself has been presented for over 100 years, this is awarded to students in the North East of England and the winner of this award this year was Daniel Gowland, an apprentice at Mears and Gateshead College. I attended the Lincolnshire presentation evening and the winners from each college are young plumbers making a start in their careers. Following conversations with them regarding our profession and their enthusiasm, I believe that these young plumbers will have very successful careers and I wish them all the best.

CIPHE MEMBER FOR 60 YEARS At the other end of their career, I had the honour of presenting an Exceptional Service certificate to Stan Rawcliffe from Lancashire Branch, who has been a member of our

Institute for 60 years. It was interesting to listen to Stan talk about his career and how he has developed over the years and the changes he has seen in the trade. Stan joined the Institute back in 1956 and became a fellow in 1975, he also received his Master Plumber status in 2003, it was a wonderful afternoon and I would like to thank the Lancashire Branch for their welcome.

JIM WALLEY Mr Jim Walley was given the Honorary Fellowship Award, I have known Jim for many years and have had the pleasure of many conversations with him. Due to his ill health, Jim was not able to attend the presentation on the night so I presented the certificate to his daughter. Since the presentation, Jim has sadly passed away, this is such a huge loss to everyone who knew him and I know that I will miss him and our little chats. I would like to give my condolences to his family. (See Jim’s obituary on page 27 of this issue.)

On 16th November, I attended the British Automatic Fire Sprinkler Association Conference in Cardiff. This was a very interesting day and as fire sprinklers are now a regulation in domestic dwellings in Wales, a feature on this will be published in a future issue. I attended PHEX in Chelsea where we did presentations and I met some CIPHE members. Finally, I attended the SNIPEF President’s evening where I met nominees of their awards and I offer many congratulation to the winners.

CIPHE NEWS

RICHARD SOPER AWARDED FELLOWSHIP

BY THE UNIVERSITY OF WORCESTER With a career spanning four decades, Richard Soper has been presented with a Fellowship by the University of Worcester, in recognition of his dedication to the plumbing and heating industry.

ichard has always maintained his roots in the Worcester area and has devoted a huge amount of personal time, energy and business expertise to the plumbing and heating sector, as well as in the wider community. Having started his working life at what he likes to call ‘the sharp end of the heating industry’, Richard joined West Midlands Gas in the early 1960s, where he embarked upon a ‘hands on’ technical apprenticeship. Further into his career, Richard joined Worcester Heat Systems Ltd as Sales and Marketing Director and in 2001 he became Managing Director of Bosch Thermotechnology Ltd. During this time, he became the Grantee for Bosch Thermotechnology Ltd.’s Royal Warrant;

an accolade the company still proudly upholds today. This was shortly followed by a CBE for Richard in The Queen’s Birthday Honours List, for services to the heating and renewable technologies industries.

NO REST… Following his retirement from the position of CEO at Bosch Thermotechnology, Richard took on the voluntary role as Director of International Development at the CIPHE. Beyond this role, Richard has also taken on a number of other positions including Chair of the Worcester Community Trust and School Governor at Regency High School, which provides care and support for students between age 11 and 19 years with a range of additional needs.

TRAINING MATTERS

ALL THAT MATTERS IN THE TRAINING WORLD

WINTER OF DISCONTENT As Carol Cannavan is now enjoying her retirement, writing the Training Matters column has fallen to me. Hopefully, I’ll live up to expectations (Carol still reads the p&he Journal…), but like anything new, there is a learning process to go through.

Jenni Preston

alking of new things, apprenticeship funding is having a rather turbulent time. In mid-November, members of the Welsh Assembly joined the Northern Ireland Executive in giving outright opposition to the introduction of the Apprenticeship Levy. Likewise, big business in Scotland is calling for greater clarity on the scheme, which is set to be introduced on 6th April 2017. The Levy is all part of Government plans to raise the number of apprenticeships and plug the skills gap. The Levy requires all employers operating in the UK, with a pay bill over £3 million each year, to invest 0.5 percent of their total annual pay bill in apprenticeships. A £15,000 allowance means that employers over the £3 million mark get £15,000 off their 0.5 percent bill. Employers who are too small to pay the Levy will only have to pay 10 percent of apprenticeship costs, with 90 percent of the costs of training paid for by the state. It all sounds good in theory. However, there are concerns that in many areas (due to other cuts) the new funding system won’t actually increase apprenticeship budgets. With two of the UK’s devolved assemblies rejecting the scheme, and Welsh Labour Skills Minister, Julie James, exclaiming, that: "The

18_training matters.indd 18

journal

levy is nothing more than a UK Government employment tax which directly conflicts with areas of devolved competence," it seems there could be a winter of discontent ahead...

QUALITY APPRENTICESHIPS ON A GLOBAL STAGE As if there wasn’t enough going on in the training industry already, the Policy Exchange has issued its latest white paper entitled, ‘Need, And Why We Don’t Have Them: How Apprenticeships should be reformed to make the UK compete on the global stage.’ The White Paper blasts the current standard of apprenticeships, claiming that the Government is wasting up to half a billion pounds on sub-standard training. We all know that the apprenticeship framework had its issues, which is why the new Trailblazers are being put in place. However, the White Paper raises concerns that even the new frameworks are not hitting world-class standards – they simply cannot compete on an international level. Locally, learning via the apprenticeship route may be improving in leaps and bounds, but we still fall far short of a world-beating system. Interestingly one of the key recommendations is to move away from the target of having three million apprenticeships by 2020. Instead, the emphasis should be on quality of the training provided, not the quantity of

learners passing through the system. It goes further to say that, apprenticeships should only receive government money if they are high quality. In essence, the bar has to be raised, but will it be enough to create an internationally renowned system? It will be a while before we know which way apprenticeships will go, but in the meantime, the new plumbing and heating Trailblazer courses look set to make a big impact on the quality of learning in our industry.

APPROVED TRAINING CENTRES It’s been a double whammy of high-profile, training centre approvals from the CIPHE of late. Pegler Yorkshire gained Approved Training Centre accreditation for their new state-of-the-art Doncaster training centre, and Worcester, Bosch Group has received Approved Training Centre status across its four Training Academies at Worcester, Clay Cross, Wakefield and West Thurrock. Congratulations to everyone involved.

Don’t forget that if you are involved in training, you can have the opportunity to have your facility approved by the CIPHE too, please email the Membership Department at membership@ciphe.org.uk

THE BONFIELD REVIEW

THE BONFIELD REVIEW – EACH HOME COUNTS Almost when no one was looking, The Bonfield Review – Each Home Counts, was published the week before Christmas.

he review into the Government’s energy efficiency policy by BRE Chief Executive, Peter Bonfield, was due to be published in March 2016, but was repeatedly pushed back. So was it worth the wait? The review was launched in 2015 by the Department of Energy and Climate Change (DECC), after the failure of the Green Deal. It was to make recommendations about how consumers can be protected and advised when installing energy efficiency and renewable energy measures in their homes. Although acknowledged by industry that the crux of the Review is admirable in its drive to protect consumers and encourage industry compliance and innovation to help to make renewable energy measures ‘commonplace’ − the recommendations of the Review, for a new ‘quality mark’ for all energy efficiency and renewable energy measures, and for ‘all companies operating in this area’ is all well and good, but it must have real weight behind it. As some commentators have said, if it simply becomes a badge for installers to win more work, the Bonfield Review will have been for nothing.

YOUR VIEWS

Each Home Counts

CIPHE CEO, Kevin Wellman, said: ‘I appreciate why the review was required as measures to reduce fuel poverty and UK carbon emissions should be encouraged. The report refers to the need to promote customer service and enhance skills, training and competency, which are all matters close to the heart of the CIPHE. It is worth remembering that the Code of Professional Standards that all individual members sign up to covers all aspects of plumbing and heating engineering and is underpinned by a robust complaints procedure Each Home Counts administered by the An Independent Review of Consum er Advice, Protection, Standards and Enforcement for Energy Eﬃciency and Registration Authority. The Renewable Energy CIPHE is intending to respond to the report and if you have any comments or observations please do write to me.

CONSULTATION;

THE KEY TO BOILER SELECTION With well over 1.5 million domestic boilers being replaced every year, out with the old and in with the new will be a familiar concept to most heating engineers.

o how do you ensure the heating system you specify and install is the perfect fit for your customers’ needs, and what happens Martyn Bridges, Director of Marketing when you can’t and Technical Support at Worcester, simply replace a boiler Bosch Group like-for-like? Martyn Bridges, Director of Marketing and Technical Support at Worcester, Bosch Group, explains: When a combi boiler needs replacing, the task in hand will be reasonably simple. Generally, your customer will be perfectly happy with the performance of their combi boiler but is simply in need of a new one, which makes a like-for-like replacement the most appropriate option. While the technology itself may be relatively straightforward to replace with another equivalent model however, there is still a degree of consultancy needed with the homeowner to ensure their needs are being met. Generally, there are four key factors to take into account with the homeowner before making any firm decision on the model of boiler required.

rerouting pipework or the relocating the flue and of course the new boiler will have a condensate discharge pipe, which the outgoing boiler is unlikely to have had. For the new condensate pipe, it must also be remembered that the preferred termination route is internally, via the waste water system.

BUILDING ALTERATIONS With the typical boiler expected to last around 15 years, there is every chance the homeowner may have had work done to their property since the outgoing boiler was fitted. The addition of an extra bathroom or shower will affect the level of hot water performance required, which is also likely dictate the most suitable boiler for the job.

HEAT LOSS It is also advisable to run a heat loss calculation on the property as the insulation values may have changed since the original boiler was fitted.

BACK TO BACK A much more complex scenario is when an existing boiler which isn’t a combi has to be replaced. It is not uncommon for a heating engineer to come across a back boiler

installed within a fireplace, behind a gas fire. Having been very popular in the 1970s, there is now little option other than to replace this type of boiler with a different type, sited elsewhere within the property and with homeowners occupying a property for an average of seven years, there is every chance your customer didn’t arrange for the original boiler to be installed and will be happy to consider change. In these instances, your customer will be used to a hot water storage system, so it is important to ask whether they are keen to continue in the same vein with their new boiler, or whether they would prefer to have a combi boiler and save space. Given modern lifestyles and the performance of the latest boilers, it tends to be the case that most back boilers are replaced by a combi model. Again, before sourcing and fitting a new combi boiler, it is important to take a number of considerations into account: Showers Is a shower fitted and is the shower mixing valve suitable for the mains pressure that the combi will generate? If not, and the homeowner does have a desire for all of the benefits of a combi, the shower may need to be replaced by a more suitable model at the same time.

The level of hot water performance required is also likely dictate the most suitable boiler for the job

FLOW RATE The first thing to establish is whether your customer is happy with their existing flow rate. Any dissatisfaction with the performance of their hot water is likely to mean the new boiler will have to be of a greater output than its predecessor. There may be more people now living in the house than when the original boiler was specified, meaning simultaneous draws of hot water are required more often than before.

LOCATION The second question to ask is whether or not the new boiler will need to be sited in exactly the same location as the outgoing appliance. Your customer may want to relocate their boiler, which will in turn affect the extent of any remedial work required − such as

20_cpd.indd 20

journal

January/February 2017

05/01/2017 12:32

CPD Your customer may say they want to move their boiler, which will affect the extent of any remedial work required

Taps How many taps are used within the property? Are any of these taps likely to be used simultaneously? An assessment of these factors will also help to inform a decision on the most suitable boiler for the property in question. Water meter Is a water meter fitted? If so, you may need to fit an expansion vessel to absorb the expansion created in the cold water mains, when an occupant runs a hot water tap. The fireplace With the back boiler being removed, an empty space will be left in the fireplace, which will need rectifying. Does the homeowner want to have a new gas fire fitted in its place? Would they prefer a wood burning stove? In the case of either, the chimney will need to be lined with a suitable new flue liner. The sealed system Replacing a hot water storage system with a combi boiler means the property will be using a sealed system, so it is important to check whether the radiators and radiator valves can handle the higher water pressure. It is generally good practice to replace the radiator valves at the same time as the heating system being altered – particularly if there is scope to replace an old wheel head radiator valve with a more modern thermostatic radiator valve (TRV).

It should go without saying that before the system is ultimately sealed, the water cleanliness needs checking and either a chemical flush or power flush procedure carried out. Storage-based systems So what about those instances where there are issues with water pressure and a combi isn’t necessarily the best option? In a property known to experience poor water pressure, a low pressure hot water storage system is likely to still be best suited, which can give rise to further considerations needing to be made prior to the installation. If a regular boiler is being installed, a heat loss calculation becomes much more important because of the fact that the outputs of most boiler ranges will go up in 3kW increments. While a boiler which is slightly oversized will always find its correct output level so won’t necessarily hamper efficiencies, a larger output boiler will be more expensive to the homeowner. The hot water storage cylinder The performance of the property’s hot water storage cylinder is also hugely important if a regular boiler is being installed. Offer the opportunity to have a new cylinder fitted with better insulation and faster re-heat times than the previous model.

Controls A boiler replacement will often present a need for new heating controls and again, consultation with the homeowner is key. A timer and a room thermostat may be the minimum requirements laid out by the building regulations, but with a vast number of options available from the most basic mechanical timer to weather and load compensating, internet-connected smart controls, it has never been so important to match the controls you specify to the requirements of the homeowner. A misplaced assumption that an elderly homeowner couldn’t possibly be internet savvy may lead to them failing to capitalise on the gains offered by the latest technology. Similarly, a mechanical time clock would be unsuitable for those wishing to benefit from different heating programs at the weekend compared to weekdays, for example.

CIPHE EXTERNAL AFFAIRS

CIPHE INDUSTRIAL ASSOCIATES

Proud to be a Professional Proud to be a Professional

MAKING A CASE FOR MOTs Roger Webb, Director of External Affairs at the CIPHE, comments on the case for annual MOT style checks to be introduced for British homes.

“

Every year, thousands of consumers around the UK invest money in improving their homes. From having new boilers installed to replacing complete bathroom suites, transformations are happening and being made possible by professional Roger Webb, CIPHE Director of plumbing and heating engineers around External Affairs the country who are doing a great job. “While that’s all well and good, and homeowners are immediately left with a shiny new shower or a more efficient heating system, this newness can soon start to wear off if aspects of the installation work are left unchecked and not maintained on a regular basis. “One of the best ways I have heard this issue being described by colleagues at the Institute is to liken the need for allencompassing home health checks to the requirement for vehicle MOTs. “After decades of education, the general public is well aware of the need to have their cars checked annually in order to tax, insure them and be roadworthy. By comparison, little thought is given to whether or not the safety critical products in our homes are especially ‘roadworthy’ and there’s no pressure for anyone to be overly concerned either. “While the situation is far from ideal, there is clearly a job to be done to spread the word that ‘prevention is better than cure’ when it comes to keeping our homes in perfect working order. As well as ensuring running costs and utility bills are kept to a minimum, safety is paramount, especially where the elderly and vulnerable are concerned; so during the course of this year expect to hear more from the CIPHE on this issue. It’s not one that’s going to go away.”

GETTING IT RIGHT FIRST TIME Paul Massey, Chairman of the Institute’s Industrial Associates (IA) Development Group, explains why getting it right first time is a win-win situation.

ince launching the ‘Proud to be a Professional’ campaign in early 2016, the Institute has focused on developing its network of Approved Training Centres (ATCs) and wider training material, to help both members Paul Massey, and non-members of the Institute Chairman of the Industrial Associates deliver the best possible solutions and Development Group service for customers. Most recently, the CIPHE launched a new series of ‘techtalk’ and ‘smarttalk’ webinars and technical papers, which tackle some of the latest installation and business challenges faced by plumbing and heating engineers and apprentices today. While this investment is supportive of the trade, one of the main aims of developing such resources is to have a positive impact on the end-customer too. Sadly, not all homeowners have a fantastic experience when work is carried out on their properties. From poor installation practices to unreliable tradesmen, instances still occur that are less than satisfactory. What we’re endeavouring to do at the CIPHE is build a 360 degree programme that includes the consumer and the plumbing and heating engineer, to increase instances where work is delivered correctly and is right first time. With around 7,000 installer members and over 180 Industrial Associate members − including some of the UK’s leading manufacturers and merchants − plus excellent links to trade and consumer associations, who else is better placed to deliver this support than the CIPHE? In this respect, we are working towards achieving a win-win situation for all parties. By providing easy access to varied educational content, the aim is to help more plumbing and heating engineers specify suitable products and deliver a job that’s done correctly, without the need for costly call-backs. This has to be a good thing because the implications of going back to correct poor work can be far-reaching. As well as being an inconvenience to the consumer − who is the most important person at the end of the supply chain − getting it wrong can lead to a loss of recommendations because the trust, respect and confidence that might otherwise have been there, quickly disappears. Through membership of the CIPHE and getting it right first time, there is more to gain and a lot less to lose!

CIPHE AND BMF ANNOUNCE

COLLABORATIVE ALLIANCE

The CIPHE and the Builders Merchants Federation (BMF) have agreed a strategic alliance that will see the two organisations collaborating in key areas.

he CIPHE and the BMF are both committed to raising quality and standards within their respective industries and progressing this ambition is one of the main objectives of their new alliance. They have also committed to have one voice on mutually agreed topics to government and other relevant bodies and to add value to both existing memberships through guidance, training and standards. As the professional body for the UK plumbing and heating industry, CIPHE has over 7,000 members including consultants, specifiers, designers and practitioners, as well as some 170 manufacturers and distributors, which support its work as Industrial Associates.

WORKING TOGETHER In recent years, the BMF has strengthened its support for specialist plumbing and heating merchant and supplier members. Initiatives include a bi-annual P&H Forum that has been instrumental in encouraging many more P&H specialists to play an active role in the BMF. CIPHE CEO, Kevin Wellman said: “There are a great many synergies between our two organisations. Working together, we can more effectively promote the need for professional plumbing and heating engineers to install quality products supplied by stockists who really understand the process. We are also looking to engage in campaigns to help

domestic end-users, for example on low carbon solutions, and to support vulnerable members of the public.” BMF Managing Director, John Newcomb, said: “Our collaboration with the CIPHE offers exciting possibilities for both organisations. The key driver is to raise the respective quality and standards in both sectors. In addition to reciprocal promotions, we will be investigating various training opportunities and are already planning a series of practical skills days next year, where merchants can gain hands on experience of typical plumbing installations.”

OBITUARY

JAMES SYDNEY WALLEY, ENG TECH, LCGI, HON FCIPHE, MCIPHE, RP 1924 TO 2016

It is with great sadness that we have to announce the death of Jim Walley, one of the stalwarts and supporter of the Institute over many years. Jim died on Saturday 12th November 2016.

im came from a family with a background in building, his father was a builder his brother was a carpenter, but Jim always wanted to be a plumber so he served an apprenticeship with an old, established Manchester plumbing company. He attended evening classes to achieve his City and Guilds Certification and when he finished his apprenticeship, he was drafted into the Army. When his basic training was complete, he was very proud to serve the rest of his Army time in Burma as one of the famous ‘Chindits’, as a muleteer, transporting Spitfire spare parts through the jungle to their destination. After his demobilisation he returned to plumbing, working on new housing projects and many large commercial contracts, these projects were revolutionary for the time and

Jim had to acquire many new skills, which he did with his usual enthusiasm. When natural gas was imported into the country, he worked on conversions with the Humphrie and Glasgow Organisation where his talents were quickly recognised. His first appointment there was as a rate fixer for every aspect of the work required to change over all the gas appliances in a dwelling from the old ‘towns gas to the new natural gas; this required him to have some delicate negotiations with the employees’ union. Later, he became the North of England Area Manager, covering North Lancashire, Cumbria and North Yorkshire. He was very proud of the fact that they never missed a ‘change-over’ date, which meant 1,000 dwellings were converted at the same time. When all the gas conversions were completed, he left the company to start up his own plumbing business. His biggest client was British Gas where he looked after the water supplies in their premises in the North West. He became an expert in the chemical cleaning of water supplies particularly in ensuring the water was clear of the microorganism, legionella pneumophila, which causes Legionnaires' disease.

He unstintingly passed on his knowledge to many other plumbers. The greatest interest in his spare time was his membership of the CIPHE. For more than 30 years, he was a member of the Manchester Branch of the Institute, where he was Branch Secretary, Chairman and subsequently President. For many years, he held the position of Vice Chairman of the North West Area Committee. A number of years ago he received the award of Honorary Member of the Institute and then followed this by becoming a Licentiate member of City and Guilds. The Institute’s Board of Trustees awarded Jim Honorary Fellowship and a presentation evening was arranged for 6th October 2016 in Manchester. Unfortunately, Jim was too ill to attend, so in his absence, the CIPHE National President, Paul Williams, made the presentation to Jim’s daughter, Yvonne. When Yvonne delivered the Award to Jim, although he was very ill, he was able to express his pride in receiving the Institute’s highest award. It is fitting that for all his work on behalf of the Institute that Jim left this world knowing his efforts had been recognised at the highest level, the certificate is now proudly displayed in Yvonne’s home. R.I.P. Stan Tildsley, EngTech, Hon FCIPHE, MCIPHE, RP

Jim’s knowledge, enthusiasm, technical capability and support for the Institute was second to none and having known Jim for over thirty years, I know how highly regarded he was throughout the industry. The CIPHE and the plumbing and heating industry has lost a great friend and unique character. Kevin Wellman, CIPHE CEO.
