IT HAS BEEN a great start to the year with

the production of the Insight Guide for the Low Temperature Heating and Hot Water Design qualifi cation. I was delighted when Lord Callanan, minister for business, energy and corporate responsibility, kindly agreed to write a foreword.

In welcoming the publication and qualifi cation he said: “This will be of great value to engineers looking to install low-carbon heating systems, such as heat pumps and hydrogen boilers, should we start to convert the gas grid in the future.

“The CIPHE’s work to promote low temperature heating skills is a wonderful example of the innovation in skills and education that will be needed to reach net zero. I would like to thank all of those who were involved in the development of the course and associated materials, and I hope to see it provided to engineers across the UK.” For further details on where the new qualifi cation is being delivered, visit the LCL Awards Learner Zone at lclawards.co.uk/learner-zone I have long campaigned for the government to provide greater support for apprentices without one employer having to commit to training for up to four years.

I was therefore pleased to hear the announcement by the PM, in his 2020 Skills Speech, that the government planned to launch a pilot scheme for Flexi-job apprenticeships (previously known as portable apprenticeships), beginning in April 2022.

The CIPHE will soon be releasing its latest manifesto, which will contain a

summary of the key issues that will need to be addressed. Once again, this will include more on the subject of education and its importance. Previous manifestos have been extremely well received and I would like to thank everyone for their positive feedback and support.

Feel free to share the manifesto with anyone you think might fi nd it of interest, especially your local MP. If you have particular observations on the issues covered, please feel free to write to me at kevinw@ciphe.org.uk.

The guide will help engineers install lowcarbon heating systems

Water waste

Renewable technologies will help to drive growth, says AMA Research

I N D U S T RY

Water heating market growth THE WATER HEATING market experienced a decline of around -13% in 2020, following the COVID-19 outbreak. However, a report from AMA Research suggests growth is expected to be reported for 2021.

The UK water heating market is influenced by factors including construction, climate, fuel prices and the development of renewable technologies.

However, renewable sources of heat are likely to drive environmentally friendly specification types and market growth.

Abdul Tantouch, research manager at AMA Research, said: “With the government’s drive towards net zero carbon emissions, there will be an increasing focus on renewable technologies, particularly heat pumps and solar energy. This development will have a considerable impact on the type of water heating systems specified.”

Great expectations

Triton says customers expect longevity

Triton Showers has revealed that following a survey of 2,000 people, homeowners expect a shower to work for eight-and-a-half years, running twice a day, and a toilet for six-and-a-half years.

“Bathroom products are expected to last a little longer, on average, than anything else in the home, but these items are often used by the whole family multiple times per day,” said Tina Simpson, spokesperson for Triton

Showers. “When choosing an item for the home, I’d always recommend checking that it is covered by a guarantee and ensuring that the manufacturer recycles old parts, where possible. There are also steps that can be taken to make appliances perform longer. For example, those living in a hard water area can install a water softener or scale reducer which can help to extend the life of showers, washing machines and dishwashers.”

The Unified Water Label Association (UWLA) has called on the industry to encourage consumers to use water wisely by promoting the Unified Water Label.

The UWLA submitted a detailed background paper for DEFRA and BEIS on water efficiency in the bathroom industry, as part of the information gathering phase, before consultations begin in 2022 on a mandatory label.

Yvonne Orgill, managing director at UWLA, said: “The Unified Water Label is an established and recognised smart tool that can help the industry motivate the consumer to recognise that water matters and make the changes required to meet the government’s targets. We have the support of manufacturers who have responded by driving forward innovation to deliver bathroom products that use less water and energy, but we must keep our focus on how these products are used in the home.

“Retailers can help the consumer understand the link between using water, energy and their carbon footprint.

Without their commitment to drive home our messages and help the consumer make informed decisions, we will fail.”

Gaps in government policy Around 18 million homes may need to install a hot water cylinder in order for the UK to meet net zero, says the Hot Water Association (HWA). Its recent report – No Place Like Home – comes with a stark warning for the government to ‘do more’.

Isaac Occhipinti, director of external affairs at HWA said: “There has been little to no focus on hot water cylinders or recognition for the vital part they play in the efficient operation of low-carbon heating. To decarbonise heating, all UK homes will need low to zero carbon heating. Most currently available low-carbon heating solutions require a hot water cylinder.

“The Government must do more to

educate homeowners, local authorities and social landlords on the need for hot water storage, and homeowners should be able to access incentives if they wish to replace their hot water cylinder with no stipulation on the type of system to be installed, only that it is a suitable replacement.”

Many homes will need new hot water cylinders

Off-grid gas solution

Liquid gas is a useful solution for off-grid sites

CIPHE.ORG.UK

The long awaited Heat and Buildings Strategy provides clarity and direction for the heating industry and consumers alike, says leading heating industry trade body, the Heating and Hotwater Industry Council (HHIC).

“As an industry, we have worked collaboratively to provide the government with the information it needed to make policy decisions on the future of heat in domestic buildings in the UK,” said Stewart Clements, director of HHIC. “I am pleased that the key evidence outlined by HHIC has been acknowledged by BEIS.” For more information visit www.hhic.org.uk

Flogas Britain, a liquid gas supplier, has partnered with heating and hot water specialist Baxi Heating to bring UK businesses a unique turnkey liquid gas solution. The new partnership means off-grid companies can switch to liquid gas from oil, solid fuel or electricity.

Heat and Buildings Strategy welcomed

“By joining forces we’re able to give customers a true end-to-end solution,” said James Goodson, strategic partnerships manager at Flogas.

“As we move towards a lower carbon future, liquid gas is becoming popular for businesses operating off the mains gas grid.”

Liquid gas could play a vital role in

helping businesses on the road to net zero emissions and these companies can support off-grid businesses as the energy landscape changes.

Nick Wilson, commercial and marketing director UK and Ireland at Baxi Heating, adds: “Our aim is to lead the phase-out of carbon intensive heating with efficient, sustainable solutions. For the off-grid community we see liquid gas as an important step that will help businesses make progress towards their net zero targets.”

Sewage dumping The high court’s decision to grant United Utilities almost total immunity for discharging untreated sewage into waterways is being challenged by the Good Law Project (GLP) and the Environmental Law Foundation (ELF). The GLP said: “People must be allowed to bring legal claims against polluters if we are to hold them to account.”

TRAINING

Online support JTL, the training provider, has launched an online channel, Tune Up, to help tradespeople develop their careers. The platform for people in the plumbing and electrical sector offers videos such as digital skills and CV writing.

HYDROGEN Karen Boswell says things “need to move more quickly”

London Housing Action Plan A new plan to achieve net zero across all London properties could see a £98 billion investment in the green economy and result in massive environmental and economic benefits, boroughs have declared.

All 33 of the capital’s local authorities have agreed a joint plan to cut carbon emissions from London’s 3,781,477 domestic buildings by retrofitting to improve energy efficiency.

Philip Glanville, mayor of Hackney and chair of London Councils’ Transport and Environment Committee, said: “Achieving net zero is a momentous challenge – but it’s also an invaluable opportunity to work with communities in improving energy efficiency, embedding green skills and driving a green recovery.

“Retrofitting on this scale will bring immediate benefits by creating new jobs while also at this crucial time lowering Londoners’ fuel bills, cutting carbon emissions, and addressing the climate emergency.”

The plan could have a huge impact for Londoners

Call for swifter action KAREN BOSWELL OBE, managing

director of Baxi UK and Ireland, has called for swifter measures to speed up the introduction of hydrogen in order to decarbonise home heating.

Speaking at the Hydrogen Transition Summit in Glasgow, on the fringe of COP26, she said more ambition needed to be shown to ensure hydrogen can take the place of natural gas in UK homes: “The infrastructure, in our view, will need to move even more quickly in order to get this market going. Heat

pumps will work in some buildings and heat networks in others, but hydrogen represents a strong opportunity to solve this complex puzzle.

“If production is ramped up enough, there are no limits on the number of homes on the current gas grid that could be converted over to utilise hydrogen. This is a race in which every horse needs to be backed.”

Baxi said that it would support the reskilling of installers who will help customers to make the right decisions about low-carbon technology.

Affordability gap New research for Baxi shows the ongoing affordability gap between low-carbon heat pumps and traditional gas boilers and proposes a £250 a year Green Heating Credit as a solution.

With the average heat pump costing £236 a year more to run than a gas boiler, Baxi cites the ongoing higher running costs as

an obstacle to progress towards low-carbon heat in the UK. Baxi research also shows how important affordability is. Saving money was seen as the most attractive reason (by 66% of respondents) for switching to a heat pump. The survey found that a Green Heating Credit of £250 per annum would

increase interest in a heat pump for three quarters of surveyed consumers, while the prospect of increased running costs is a disincentive for 40%.

Karen Boswell OBE, managing director of Baxi UK and Ireland, said: “Heat pumps could play a part as we decarbonise heating, but we need to bridge this affordability gap.”

Action on unsafe work A self-employed gas engineer, trading as Shabba Gas Services Plumbing and Heating Engineer, has been fined for carrying out unsafe gas work after installing a boiler which was later found to have multiple installation faults.

An investigation by the Health and Safety Executive (HSE) found that the flue had been assembled with parts from more than one manufacturer, water was leaking from the joints and it had been propped up with rubble.

Dexter Regis pleaded guilty to breaching Regulations 5(3), 26(1), 26(5) and 27(1) of the Gas Safety (Installation and Use) Regulations 1998 and was sentenced to 15 months imprisonment, suspended for two years with requirements to undertake 200

hours of unpaid work and a tagged curfew between 9pm6am for three months.

HSE Inspector Charles Linfoot said: “This case could have had tragic consequences.

It highlights the importance of engineers working to the correct standards and installing gas boilers in compliance with manufacturers’ recommendations, using the correct flue which is properly supported.

“HSE will not hesitate to take appropriate enforcement action against those that fall below the required standards.”

The new suite of resources is easy to access

GTEC launches new e-learning platform GTEC HAS LAUNCHED a new online tool, MCS Made Easy, designed to help installers comply with MCS 001, which covers the key requirements to become MCS Certified. The programme includes a webinar and supporting documentation.

Developed by GTEC and Learning Lounge, MCS Made Easy provides a package of support, including tutorials, Q&As and real-life scenarios.

Griff Thomas, managing director for GTEC, said: “MCS Made Easy is a simple to use, informative resource that should really help installers gain a good understanding of what can seem a daunting task.

“Whilst systems are crucial to maintain standards in renewable technologies, they do not need to be

fully documented and complex; our webinar demonstrates this and will hopefully give installers a great basis to get their certification in place.

“It is also really important that we create a transparent route to give consumers the confidence to ‘go green’, while providing installation companies with a clear and stress-free framework to follow.

“Thanks to this new way of learning, we hope more building services installers will have the confidence to upskill into renewables and gain MCS certification – something that is much needed to meet the growing demand for low-carbon technologies.”

BUSINESS Some businesses in the trades are struggling to recover from the effects of COVID-19

Trades feel COVID effect ALTHOUGH UK TRADES are on the road to recovery as the threat from COVID-19 recedes, soaring costs mean one-in-eight fears failure within a year, according to a report by field service management software provider, BigChange.

Demand for trades soared by 70% post-lockdown and turnovers are up 79%, but COVID-19 compliance issues and rising costs mean just half of firms are currently profitable, leaving 13% of firms fearing they could go out of business in the next 12 months.

Despite rising turnovers and average price increases of 47%, fewer than half of trades businesses (48%) said they were profitable in the year to July 2021. Richard Warley, chief executive officer of BigChange, said: “While demand

for the trades has boomed since the first lockdown, this backbone of the economy is not as strong as it might look.

Only half of firms are profiting from this extra work. There’s a big difference between growing and growing stronger.

“The strong, profitable businesses are succeeding by working smarter to stay in control of their operations, keeping a lid on costs, and making their teams more productive.

They are using technology to improve management oversight, plan better and automate processes, and improve communication and response times as part of efforts to make the customer experience their new source of competitive advantage.”

Biofuel breakthrough Grant Engineering has pioneered a major breakthrough with biofuels, a development that could help reduce carbon emissions in rural, hard-to-heat homes with minimal disruption and reduced costs.

The introduction of this unique product was the catalyst for a sustained increase in boiler efficiencies, leading to a reduction in running costs for homeowners and bringing about a major transformation across the whole oil boiler industry.

The use of HVO, either at 100% (resulting in a reduction in carbon emissions of up to 88%) or a percentage blend with kerosene, will allow rural properties to transition to a renewable, green alternative from 100% kerosene at an affordable cost and with minimum disruption to their home lives. Biofuels provide a viable alternative for older buildings which are currently incorporating a high temperature heating system, such as an oil-fired boiler.

“The use of HVO biofuel is incredibly exciting because it provides a further solution to low-carbon heating for homeowners and their installers,” said Paul Wakefield, Grant UK’s managing director. “It could enable existing off-gas residential homes, which are currently being heated by oil, to decarbonise their heating without having to undergo significant changes to their home.”

Education should play an integral role for installers” With an aptitude for plumbing evident at the tender age of 13, it seemed that Paul Williams was destined to be an installer.

His career has seen him take on a variety of roles, including the accolade of the youngest Master Plumber and National President of the CIPHE

PAUL WILLIAMS’ father was a plumber, so going into the family business was always a strong possibility. During his childhood he worked alongside his father after school, so by the time he turned 16 he had plenty of experience under his belt. It was then that he started a plumbing course at Ammanford College, working as an apprentice for his dad’s business.

“I have to admit that I wasn’t the greatest of students, but I always enjoyed the practical aspect of learning,” recalls Paul. “I did, however, pass the course and was advised by my lecturer to continue onto Level 3.”

On completion of his course, Paul worked with his father for some time, mainly doing domestic plumbing and heating jobs, but also carried out a lot of bathroom installations, too.

“I worked with my dad for around 10 years, but I wanted to do more central heating work and boiler servicing, so I decided to go self-employed,” says Paul.

14 P&H ENGINEERING | QUARTER ONE | 2022

PAUL WILLIAMS E n gTe c h LCGI MCIPHE RP RHP Director, Albert Williams Ltd Installer with a history of working in the construction industry. Former lecturer and past National President of the CIPHE

Shortly after branching out on his own, Paul was offered a position lecturing in plumbing at Ammanford College in South Wales. It was during his two years here that he became more involved with the CIPHE at a national and a local level. His next role was as a lecturer in plumbing and assessor at Gower College in Swansea.

With help and advice from Kevin Wellman and Colin Stainer of the CIPHE, Paul set up the Carmarthenshire branch in 2004. Then followed the opening of the South Wales branch, where he was involved with area committees and became a deputy area co-ordinator, assisting the area co-ordinator and attending meetings.

In 2007 Paul became a professional standards inspector for the CIPHE and still attends training.

He believes this helps with evaluating new members who don’t quite meet the criteria, as well as assisting with any complaints raised between consumers and members.

“It was the same year that I decided to take a

break as my mental health was suffering,” explains Paul. “It was then that I realised that, even though I enjoyed the teaching, the environment didn’t suit me at the time, so I went back to working with my dad until he retired in 2017.”

Paul started up his own company, but soon reverted back to his father’s company name, Albert Williams.

“Having worked with some customers for over 20 years I had built up good relationships,” he explains.

“You get to know people and their whole family. I do a lot of call-outs for small things like changing washers because it’s a good way to check in on people, some of whom can be very lonely.”

Professional agenda “I’m probably better known for my role as National President of the CIPHE from 2016-17,” says Paul.

“It was a tremendous year – I met many wonderful people at great events, such as presidential dinners, plaque presentations to our approved training centres, which included colleges. It was great to speak to both lecturers and students. I attended

“Water regulations should be covered in level two as standard” award ceremonies, plumbing exhibitions, branch dinners and, of course, presented Stan Rawcliffe and Jim Walley with their membership awards.

The honour of representing the members at these events was fantastic and something that I will never forget.”

Paul has also helped to promote WaterSafe, the free online directory and national accreditation body for competent and qualified plumbers in England, Scotland, Wales and Northern Ireland, via radio interviews and press releases. The latest of which

was what to do in case of emergencies such as cold spells, ensuring people know where their stop tap is and how to find a plumber who will come out and do a good job for a fair price.

“Education should play an integral role for installers, particularly when it comes to water regulations,” says Paul. “I believe that water regulations should be covered in level two as standard as it deals with back flow prevention and the risk of cross contamination if it is not installed correctly.”

Sustainable movement The government’s plans to implement greener heating technologies is a subject that every installer has an opinion on and Paul agrees efficiency is key, but this doesn’t necessarily mean investing in new technology.

“Although the industry has evolved, there is heating in homes that has been around since the 1970s, so it’s these systems that need to be looked at,” says Paul. “The heating courses are good because they focus on the importance of design and how this impacts on efficiency in homes.”

As alternative fuels and technologies are introduced, Paul believes it’s important to match the right system with each home, whether that’s LPG, HVO or heat recovery. The key is to ensure that existing set-ups are as efficient as possible and that means educating consumers on how to use their systems to maximum effect.

“Heat pumps may be suitable for certain positions, but this will not help with heat poverty,” points out Paul. “A lot of people simply don’t have tens of thousands of pounds to spend on a new heating system.

“People are making more enquiries about heat pumps, but my concern is when you have got apprenticeship schemes by certain companies who offer short courses to boost the numbers of qualified installers, this could result in poor set-ups, which could be the downfall of the industry.”

As National President of CIPHE, Paul attended many award ceremonies, plumbing exhibitions and branch dinners

The COP26 set out a roadmap to zero carbon success, which relies on a cohesive approach to new technology

INVESTING IN THE FUTURE A

lthough the catastrophic predictions for the earth’s future may seem like the plot to a high-octane action film, scientific consensus is that the reality of inaction is frighteningly real. The race to prevent further global warming is on, but it’s going to take the combined efforts of the entire globe to ensure a happy ending.

The COP26 conference in Glasgow last autumn managed to agree on key actions to address climate change and a way forward for all countries involved to meet their decarbonisation targets, with ambitious policies for action.

The Energy Saving Trust said: “While acknowledging that the cost of inaction will be far greater than the investment required, the strategy also highlights that early action to achieve net zero offers multiple opportunities to strengthen the UK economy and level up.”

Collaboration The emphasis on international collaboration on innovative climate action across all sections of society was recognised by all who attended COP26. However, the economic inequalities that prevent some countries from levelling up require a delicate balance in order to mitigate their impact.

The topic of finance was extensively discussed, with the need to increase support to developing countries apparent.

Calls to double finance for adaptation to these countries was agreed by all.

The talks also worked on a programme to define the global goal on adaptation, identifying collective needs and solutions to the climate crisis already affecting many countries.

To mitigate the persistent gap in emissions, an agreement was made to reduce the gap and to ensure that the rise in the average temperature is limited to 1.5 degrees.

Alok Sharma, UK President of COP26, said: “We can now say with credibility that we have kept 1.5 degrees alive, but its pulse is weak and it will only survive if we keep our promises and translate commitments into rapid action.”

Unrealistic expectations?

A call to action was delivered by the government in the form of The Heat and Buildings Strategy, which was published in October 2021. This set out how the UK will decarbonise homes and commercial, industrial and public sector buildings, as part of setting a path to net zero by 2050.

Despite the fact that the majority of the heating and plumbing industry would agree that a shift to net zero is vital, there is not much confidence that it is achievable in the current circumstances. In fact, according to research by Bramble Energy, 52% of the UK construction industry is not confident they will achieve net zero by 2050*.

The construction industry contributes to over 38% of the UK’s total carbon footprint, so in order to reduce to zero by 2050 it needs to address three key challenges, which includes: • Education and an understanding of the solutions available • A net zero ambition which is realistic and, ultimately, achievable • Full transparency on the government funding available “The construction industry is already demonstrating clear intent with the launch of major projects like HS2,” says Peter Sayce, chief product officer at Bramble Energy. “Yet our survey

GOVERNMENT SUPPORT “We can help meet COP26 objectives by developing appropriate training and education schemes in new technologies now. This needs immediate government and industry financing and support. Our industry can help lead the way by encouraging the public to install appropriate, more energy efficient installations when replacements are due.”

“Clearly we all need to take action to save the planet”

Panellists from Viessman, Velux, Johnson Controls and The Worl on stage at COP26 in discussion during a session on ‘Creating Liveable Spaces: Homes, Heating, Cooling, Retrofitting’

revealed some genuine challenges that continue to face the sector in order to achieve net zero. Yes, roadmaps are being put into place by industry experts, but the picture being painted is that all parties have to take their share of the responsibility. Construction firms have to become better educated on solutions and support available, and the government has to be more transparent in its support.”

To tackle the issue of reducing carbon emissions from UK homes, the government has been championing heat pumps as the way forward.

PRO-CHOICE “We are pleased that government has recognised heat networks and hydrogen as the way forward for sectors that will be difficult to decarbonise with electricity. A hydrogen economy will strengthen energy security and give consumers a choice in how they want to protect their comfort as well as the planet.”

– Steve McConnell, director of the Industrial and Commercial Heating Equipment Association (ICOM)

However, although a good solution, this certainly isn’t a one-size-fits-all situation. The industry needs to challenge the assumption that heat pumps are the only way to achieve targets.

underfloor heating. Local or district heating schemes could provide a solution to these problems where groups of properties cannot be easily converted individually to the new technology.”

The government has tipped hydrogen as one of its carbon–cutting solutions, with plans to kickstart a world-leading hydrogen economy set to support over 9,000 UK jobs and unlock £4 billion investment by 2030.

The UK’s first-ever hydrogen strategy follows the Prime Minister’s ambitious 10-point plan for a green industrial revolution to meet its target of 5GW of low-carbon hydrogen production capacity by 2030 – the equivalent of replacing natural gas in

powering around three million UK homes each year, as well as powering transport and businesses, particularly heavy industry.

Kwasi Kwarteng, business and energy secretary, said of the plans: “This home-grown clean energy source has the potential to transform the way we power our lives and will be essential to tackling climate change and reaching net zero. With the potential to provide a third of the UK’s energy in the future, our strategy positions the UK as first in the global race to ramp up hydrogen technology and seize the thousands of jobs and private investment that come with it.”

Suppliers, including Bosch, have developed hydrogen-ready boilers that are able to function off the current grid infrastructure, meaning limited disruption for customers and similar installation. However, concerns remain around the cost to UK households and the scalability of this target.

“Further consideration should be

government if the current proposals are to be implemented.”

Although touted as a clean, natural gas, the fact remains that currently the bulk of the UK’s hydrogen resources are produced from fossil fuels. However, renewable sources such as wind, solar, geothermal or biomass can also be used to produce hydrogen.

“Our trade is reliant on fossil fuels to an extent,” says Jimmy Hendry, EngTech, AfCGI FCIPHE RP, who is a plumbing lecturer at Inverness College.

“We are seeing a push towards hydrogenated vegetable oils (HVO)

in boilers and a push to hydrogen gas boilers, but given that the bulk of our hydrogen comes from fossil fuels it seems to be just a shift away from the usual to try to distract from the real agenda.”

Demand for gas installers Despite the focus on renewable fuel resources, the fact remains that there are currently around 22 million gas-heated homes in the UK. This means that there will be appliances which will require safety checks, maintenance and repairs for many years

FIT FOR PURPOSE “We need to look at housing stock and see what is best suited for our energy use.

to come, so there will still be demand for gas qualified installers.

“Traditional heating qualifications are often pre-requisites to heat pump and renewables training and leading industry authorities agree that the market will rely on those with existing skills,” points out Mark Krull, managing director of training provider LCL Awards. “The Heat Pump Association says that ‘the initial growth in heat pump installers will need to predominantly come from those already installing traditional heating systems.

The fundamentals of heating do not change with a switch to heat pumps, in the current installer base many of the skills required for low-carbon heating installation are already in place and these will need to be built upon.’

“Taken at face value, some media noise about the rapid expansion of the

“Industry authorities agree the market will rely on those with existing skills”

heat pump market and developments in hydrogen may cause concern to those considering training for a career as a Gas Safe registered engineer. However, you don’t have to look too far beyond the headlines to see that gas engineering offers a prosperous career now that opens many doors to ongoing success in a low-carbon future.”

Another issue that could arise due to the increased focus on renewable energy sources is unqualified installers attempting to work with gas appliances.

“It’s important to have a proper professional registration and competency scheme to work in the related tasks, so we don’t end up with cowboys jumping on the back of the grant schemes,” says David Bunce, trainee plumber.

This is a sentiment that is echoed throughout the industry. In fact, Master Plumber Jimmy Hendry currently has a petition under approval in the UK parliament to ensure the safety of consumers. “The petition for ‘No Gas Safe card = No Sale’ aims to cut down on the amount of unregistered gas engineers buying and fitting boilers,

“We need a strong labour pact to attract new professionals”

cookers and fires with no qualifications,” he says.

The aim of the petition is to instate a register of purchases and installations to reduce the number of unqualified installations that could potentially cause fatalities.

“As the construction sector produces significant carbon emissions it’s clear that we collectively have a responsibility to support the government’s net zero aspirations,” says Kevin Wellman, chief executive officer of the CIPHE. “However, I fear the current pandemic and the parliamentary issues are proving a huge distraction from the real issues.

“It’s vital for the industry to give accurate and consistent messaging and I commend the industry trade press for the support they are giving to this topic.

There are numerous options available to reduce our carbon footprints, so it’s imperative that installers and designers are adequately skilled in these technologies.

“The key to a successful rollout of these technologies is for designers to consider the long-term implications of installations and the industry needs to ensure quality products that are installed and maintained by qualified professionals.

“Reaching the government’s targets will require a swift, sustained and collaborative approach across all sectors.”

RIGHT AS RAIN As the planet’s temperature continues to rise droughts are becoming more severe across the globe. Is rainwater harvesting the solution to saving this scarce resource?

A

lthough it’s one of the world’s most precious resources, with shortages all over the globe, water management is seriously lacking. According to the Global Water Partnership (GWP), 2021 saw record-breaking droughts, which are set to increase in frequency and severity. The Standardised Precipitation -Evapotranspiration Index (SPEI) Global Drought Monitor’s records indicated that in the US nearly half the mainland has been afflicted. Brazil experienced one of the worst ever recorded, and in Madagascar, drought has left hundreds of thousands of people malnourished.

“Rainwater could be one way to reduce our use of public water supplies”

Rainwater harvesting is one solution that many countries have been investing in to tackle water shortages, but in the UK, where drought is less common or severe, this model is being used to reduce water consumption in an attempt to preserve our fresh water supply.

Rainwater harvesting (RWH) is the practice of diverting rainwater that falls on roofs or other surfaces of buildings, storing it and reusing it. This is something that is increasingly being used in the UK as a means to reduce our reliance on mains water, providing they are installed correctly.

“The UK doesn’t have enough water to meet growing demand, so using rainwater could be one way to reduce our use of public water supplies,” suggests Paul Millard, technical manager at Water Regs UK. According to the Environment Agency: “If no action is taken between 2025 and

22 P&H ENGINEERING | QUARTER ONE | 2022

2050 around 3,435 million extra litres of water per day will be needed for public water supply to address future pressures.”

The UK public are on board, according to Water Regs UK, with nearly half of British people welcoming the introduction of RWH into their homes.

However, tradespeople should be aware that installing a rainwater harvesting system is classed as a material change of use, so the local water company must be notified about the installation 10 days prior to work commencing.

“Systems can be directly or indirectly supplied,” explains Paul. “For a direct-supply system, water is pumped directly from the main storage tank, usually a buried tank, to the points of use, for example toilets and outside taps.

Indirect systems are relatively similar to this in that they just add an extra step, pumping water from the main storage tank up to an intermediate cistern at high

CIPHE.ORG.UK

R A I N WAT ER H A RV E S T I N G | F E AT U R E DID YOU KNOW? Rainwater harvesting systems typically reduce mains water use by around 50%

level, for example in the roof space, from where it can then be fed by gravity to the points of use. Some systems will treat the water to improve water quality.”

How it works There are a number of different rainwater-harvesting systems available with a range of features. According to the Environment Agency’s Harvesting Rainwater for Domestic Uses information guide, BS 8515 gives guidance on the design, installation and maintenance of RWH systems for the supply of non-potable water in the UK, and applies to both retrofitting and new builds.

Rainwater harvesting is an important part of sustainable building

The code of practice covers three basic types of RWH systems:

•W ater collected in storage tank(s) and pumped directly to points of use •W ater collected in storage tank(s) and fed by gravity to points of use •W ater collected in storage tank(s), pumped to an elevated cistern and fed by gravity to the points of use With water collected in storage tank(s) and pumped directly to points of use, rainwater is collected and leaves and other large solids are prevented from entering the holding tank. The water enters the tank through a smoothing inlet, which stops sediment at the bottom of the tank from being disturbed by rainwater entering it.

A suction filter prevents the uptake of

floating matter when the water is drawn up for use. As the water is non-potable, it travels through a separate set of pipes, as specified in the Water Supply (Water Fittings) Regulations 1998, and a pump pressurises the water.

The control unit monitors the water level in the tank. If the water level in the tank drops too low, the control unit will trigger an automatic changeover to mains water supply. The system must have a type AA air gap installed in order to prevent back-flow of rainwater into the mains.

When the water in the tank reaches a certain level, an overflow trap allows floating material to be skimmed off into the storm drain. A non-return valve needs

to be fitted to prevent contamination of the tank by backflow, together with a rodent barrier.

Possible issues Whilst rainwater harvesting systems have a significant role to play in reducing water consumption, it’s important that they are installed correctly to avoid drinking water contamination.

“Rainwater harvesting and water re-use systems need to be well designed, as well as being installed and maintained by those who are competent to do so,” says Paul.

“It is critical that building owners and tenants understand the risks of incorrectly installed systems and ensure they only use suitably competent professionals to maintain their system.

“For reliability, a mains water back-up may be required and without appropriate backflow protection, will be cross-connected and risk contamination of the drinking water supply. That is why it’s so important that appropriate back-flow protection is installed as well as colour coding of pipework when carrying out work on the plumbing system. The colour coding should help to prevent anyone cross-connecting at a later date, as

GUIDANCE A water abstraction licence may be needed if harvested rainwater is mixed with ground or surface water, which will be abstracted or transferred

“Rainwater harvesting and water re-use systems need to be well designed”

pipework could be mistaken for wholesome water supplies.

“British Standard BS 1710:2014 provides details on the appropriate identification colour codes which should be used. It is also good practice at the point-of-use appliances such as toilet cisterns, outside taps, and washing machine connections to have labels indicating ‘Not drinking water’. This is essential particularly on outside taps so that visitors, such as friends, tradesmen and window cleaners, for example, understand the water is not wholesome mains water and can take the appropriate precautions when using it.”

Other issues with these systems may include traces of atmospheric and environmental pollutants and the water is likely to contain some animal and bird faecal matter. According to Water Regs UK, all alternative water supplies must be considered a fluid category five risk, that is to say they pose a serious health hazard.

Other alternative water supplies from bore holes and rivers are likely to have a wider range of pathogenic organisms and possibly faecal matter and are placed in the same category. “Therefore, appropriate backflow protection for fluid category five should be installed,” insists Paul. “Collected rainwater can also become discoloured, smell and stain water fittings – particularly if it’s stored for longer periods and stagnates. That is why some systems will treat the water, but these will require greater maintenance.”

Rainwater harvesting systems store water in a variety of different ways

Upkeep When it comes to maintaining rainwater-harvesting systems it’s vital to check the manufacturers’ recommendations. Thorough maintenance is important to ensure that end users achieve the maximum benefit.

“A few simple frequent checks may be all that is needed for optimum system

24 P&H ENGINEERING | QUARTER ONE | 2022

Risky business?

Proper installation and regular checks should ensure water safety According to the Rainwater Management Association, there are no recorded cases in the UK of legionella or other contagions arising from a RWH installation: “Independent studies have shown the possibility of contagion to be very unlikely. It is recommended that the tanks used to store harvested rainwater are installed underground as they are large, and not particularly sightly. This means that the water is stored in cool and dark conditions which are not conducive to the cultivation of legionella.

Where the harvested rainwater is to be stored

above ground, protection from direct sunlight is recommended.”

Backflow prevention The Water Supply (Water Fittings) Regulations 1999 require that sufficient backflow prevention is provided to prevent contamination of the public mains water supply. This is usually in the form of an air gap that prevents non-potable water entering the mains water supply. Back-flow prevention for specific appliances should be discussed with the manufacturer to ensure suitable category five (air gap) backflow prevention

has been incorporated into the appliance. For more information on back-flow prevention and types of air gap, see the WRAS10 website.

According to DEFRA: “A Water Safe Approved plumber should complete regular checks on these systems to ensure the Water Fittings Regulations 1999 are being adhered to and any maintenance recommended by the system manufacturer should be followed.”

functions, as the manufacturer intended,” says Paul. “Users should be made aware of this and advised that it is in their interests to follow the manufacturer’s specified maintenance requirements.

Installers should encourage end users to keep a record of what system has been installed and to share this information with the new homeowners if they sell the property or with any installer working on the plumbing or rainwater harvesting system.

“This is vital as rainwater harvesting systems can be altered and become non-compliant,” points out Paul. “One water company, which inspected over 1,000 rainwater harvesting systems over five years, found around 70% failed to comply with the water fittings regulations, even though they had been inspected on installation and initially complied.

Worryingly, a third of these failures were due to cross-connections, often put in to deal with faulty pumps or blocked filters – changes made post installation.”

Installers can help educate end users about the importance of keeping rainwater harvesting systems compliant with water regulations. The requirements of the Water Supply (Water Fittings) Regulations and Byelaws apply to properties that have alternative water supplies, such as rainwater-harvesting systems.

“The regulations and byelaws are

CIPHE.ORG.UK

intended to protect public health and make sure there is no waste, misuse, undue consumption, contamination or erroneous measurement of public mains water,” explains Paul. “Supporting the regulations, British Standards have published the standard BS EN 16941 Part 1:2018 for rainwater harvesting systems which covers their design, installation and maintenance. The document includes water quality requirements for the end users where the water is not required to be wholesome.”

Rainwater systems that treat water to higher standards to be used for washing or drinking would fall under the Private Water Supplies Regulations that deal with the use of abstracted water intended for human consumption, domestic purposes and food production. These basically follow the requirements set out for public drinking water standards and all rainwater harvesting intending to provide water for consumption or food production.

“Aside from what is required, it is also a good idea to make sure everything is properly recorded, pipes are marked and signs at taps and appliances are used so that any operator is fully aware of the quality of water being supplied,” advises Paul. “This will help users take the appropriate measures so that their

Toilet flushing uses the second highest percentage of water per person per day. Substituting mains supply for rainwater for this could potentially reduce pressure on mains supply by approximately 39 litres per person per day (l/p/d), or 26%, reducing the average daily use of mains water to 111l/p/d. If rainwater was also used to supply the washing machine and water to the garden, then the demand on mains water could be reduced further.

The future of learning W

ith the heating and plumbing industry already stretched to capacity and the introduction of new carbon targets from the government, there needs to be a robust plan to recruit and educate within the sector.

Ros Parker OBE, who was recognised in the Queens New Year’s Honours List 2021 for her substantial contribution to services in adult education and the community in Southend, has a vision for the future.

In 1996, as a single mum who left school with no qualifications and barely enough food to feed her young family, Ros started attending an adult education class studying creative writing.

Four years later, Ros had achieved a BA Hons degree and a Master of Science in Education and Training Management. This enabled her to secure her first leadership role in education as Principal of Prospects College of Advanced Technology, Essex.

It was here that she developed and implemented virtual and augmented reality for plumbing and heating engineering, electrical installation, and air conditioning and refrigeration, which gained national recognition.

Ros developed and implemented apprenticeship standards across construction and engineering, providing 1,500 young people with the skills and development required for sustained

CIPHE.ORG.UK

employment in the future.

In her first year in the role of Principal of Southend Adult Community College, she secured a provision across multiple trades to ensure young people and adults develop the skills they need to meet the skills gaps and progress into apprenticeships.

She is passionate about providing high-quality education that enables young people and adults to access the

skills they need to enter into construction and engineering, where there is a significant shortage of skilled practitioners to meet the demand.

At present she is working alongside the CIPHE to accelerate the skills offer and promote opportunities for young people and adults that enable them to develop their career opportunities across the sector.

Spreading the word With demand for skilled tradespeople at an all-time high and government targets putting increased pressure on the industry, the need for investment in the education sector is vital.

“The skills shortage is a very real issue and there are many challenges when recruiting a skilled workforce which have been exacerbated by the pandemic,” says Ros. “Recruiting apprentices has many benefits, with education providers working alongside employers to get the right match of skills and experience that will bridge the skills shortages. For me, co-production of a meaningful programme of work and learning between education providers and industry would help to reduce the shortage of skills.”

With so many courses available, young adults can struggle to navigate their way through the options. However, the National Careers Service and the

National Apprenticeship Service are great places to start, according to Ros. “Good information, advice and guidance sessions can really help young people and adults to make the right choices for them,” she says. “Those that know exactly what they want to do and the pathway they want to take within the industry should look for good quality providers – a guide would be to look at the provider’s latest Ofsted report alongside reviews, and learner and employer feedback.”

The skills shortage isn’t just limited to installers, but lecturers too. It stands to reason that if more people need to be trained, there need to be more qualified

teachers too. However, this is also a major problem in the sector at the moment.

“If I could solve the problem of lack of lecturers I could probably retire in style!” jokes Ros. “Seriously though, it is a challenge and there have been many interventions around flexible market rates and golden hellos, but this simply moves the problem around and provides a short-term solution.

It would be great to flip the problem and tackle it in a different way, for example challenging the current delivery model to bring flexibility and co-production between employers and providers.

Above: Ros helped to upskill hundreds of people during her time at Southend Adult Community College

CIPHE Education Strategy Group The CIPHE Education Strategy Group (ESG) is a sub-group of the Membership Registration and Education Committee (MREC).

The ESG acts as an independent and professional leading authority to and on behalf of the plumbing and heating industry by raising educational standards, guidance, expertise and educational innovation.

It will liaise with government on educational matters concerning plumbing and heating engineering, develop progression in education, links with CIPHE membership, and liaison with appropriate educational establishments.

The principal tasks of the ESG: • Develop a five-year

strategy regarding education, which aligns with government policy • Ensure government consultations on educational matters relating to the plumbing and heating industry are attended to • Communicate with government officials and relevant authorities to further and advance education and training

procedures on behalf of the plumbing and heating industry • Arrange regular internal audits in respect of CIPHE’s licence with the Engineering Council • Update career pathway information and disseminate it to colleges and private training centres • Seek and maximise funding opportunities in support of CIPHE’s

Industry support “The CIPHE plays an incredibly important role in promoting continued professional development within the industry, in understanding the changing skills needs and gaps that will inform the education sector in the development of its programmes,” says Ros. “It has a significant part to play in promoting high standards of work across the industry and this starts with how effectively people are trained and developed.

“Immersive technology and the internet are excellent support and enablers”

“There are many challenges when recruiting a skilled workforce”

“I hope the group will shine a light on the education and skills needs of the industry, promote pathways that enable progression across the industry and work alongside employers and providers to reduce the skills shortages.”

Given the government’s announcement about the grants to encourage homeowners to upgrade to heat pumps, Ros believes the incentives provided by the government will encourage upgrades, but when it comes to maintenance of these new technologies there may be a lack of skills to meet demand.

“I would like to think that the government has a pipeline of industry professionals it is working with to understand the scale of need and demand, alongside the development of an upskilling programme that incentivises those displaced through the pandemic to retrain,” says Ros. “It would be great to think that there is a five-year-plan in place to retrain, upskill and facilitate new opportunities for industry professionals to transfer into sustainable options for the future.”

Looking ahead Ros has a clear vision for the future of the industry, which she shared in 2019, predicting that education would take place in dedicated industry-specific shops in empty high streets, college departments would co-locate with employers who would use empty office space as desk-based roles would work from home.

She also believed that training and development would be live-streamed worldwide to exchange excellence in the industry; virtual and augmented reality would be used for work experience and to develop skills safely, whilst optimising lecturers’ time, and employers and industry professionals

CIPHE.ORG.UK

would be part of a training academy to facilitate the learning of new skills whilst retaining their industry role flexibly.

“By March 2020 we were in lockdown and the world changed dramatically.

Much of what I set out happened within 48 hours,” says Ros. “I think I will stop setting out my 10-year vision!”

All jokes aside, Ros believes that the internet will play an important role in providing training support or vocational qualifications moving forward.

“Using digital resources, immersive technology and the internet are excellent support and enablers of learning if used well,” she asserts. “We have seen its impact during the pandemic. However, it lends itself better to some sectors more than others.

Additionally, we have seen the real value in practical problem solving with others in a room together. The development of

hand skills needs a practical space that is safe for learners to gain the skills they need for work.”

She also underlines the importance of face-to-face working alongside these new digital solutions. “Let’s not forget the value of social interaction that builds a resilient workforce, a team that can work together, support and coach each other.

We have seen the impact that being isolated from others has on mental health and physical wellbeing so it is about a balance: where technology is an enabler, it should be used to best effect, but not to the detriment of building a strong and skilled workforce of the future.”

ith a significant shortage of qualified heating and plumbing engineers in the UK, there is a desperate need to attract higher numbers and a more diverse demographic into the industry.

the EU being able to work in the UK, could see price rises for consumers and more unqualified people entering the sector, so it’s in everyone’s interest to encourage more apprentices into the industry.

“Giving access to all groups of people in society, including disadvantaged groups who would not generally get access to business and industry due to their circumstances, is incredibly important in my view,” says Jason Clark, LCGI EngTech FCIPHE RP MIOD. “This is something I do as a business owner on a regular basis as part of my company commitment to social responsibility.

“It’s important to include a more diverse demographic to show that the industry is open to all. We can do this by way of highlighting people that have achieved and become a trailblazer, such as the current first black president of the CIPHE, Mel Gumbs. I hope to continue to improve awareness and include a wider demographic by hosting students and apprentices at my business for inspirational talks.”

The industry is beginning to move away from the stereotypical view of what a tradesperson should look like and consumers will ultimately benefit from the variety of skills a diverse industry will bring.

Underutilised resource Historically, the heating and plumbing industry has been male dominated, but the number of female tradespeople is on the rise.

According to Direct Line, there were an estimated 15,000 tradeswomen working in 2009 compared to 33,000 in 2019 – that’s an exponential increase of 120% in a decade.

So what’s changed? Well, in addition to a change in public perception of traditional male and female roles, the pandemic has driven interest in the industry. The roles of heating and plumbing engineers were deemed as essential throughout the COVID-19 outbreak and therefore offered job security in a time of uncertainty. In fact, according to a study by Powered Now, during 2020, 21% of UK women contemplated a career in the trades. The same study also found that 15% of women already working in the industry saw record demand for their services.

Quality counts Office of Qualifications and Examinations Regulation (Ofqual) regulates qualifications, exams and tests in England. It aims to maintain standards and confidence in qualifications.

“We enjoy a unique position in that Ofqual is both a regulator and an external quality assurance provider of apprenticeship end-point assessment,” says Andrew Bell, media

CIPHE.ORG.UK

and campaigns manager, Ofqual.

“This means that apprentices can be confident that their assessment will be of high quality, whichever end-point assessment organisation is delivering it, and where and when it is carried out.

“Our register of regulated qualifications is a good place to start for those considering appropriate qualifications for a range of

pathways. Advice beyond this is a matter for the Department for Education and the Institute for Apprenticeships and Technical Education.”

The Trade Taster Days allow young people to tackle practical challenges

“Sharing our knowledge with the younger generation is crucial” in practical challenges. This hands-on experience not only gave students the opportunity to try tasks for themselves, but increase their knowledge of possible future career opportunities.

The aim of this experience was to allow students to make more informed choices about employment options when they leave school.

“Sharing our knowledge with the younger generation is crucial when it comes to bridging the skills gap in our industry,” says Rob. “Taking the time to explore the different parts of a boiler, solve fun challenges and interact with students can

make all the difference when it comes to encouraging younger people to pursue a career in the heating industry. This is why trade taster days are so invaluable and give us a great chance to raise the profile of just how diverse and rewarding working in this sector can be.”

Government support In August last year the government launched a flexi-job apprenticeship offer in response to the changing world of work. The aim of the flexi-job apprenticeships is to help employers overcome structural barriers to make greater use of

32 P&H ENGINEERING | QUARTER ONE | 2022

apprenticeships. They will also support businesses in all sectors to make a sustainable investment in the skills they need to grow, and build a diverse talent pipeline for the future.

In sectors where flexible or project-based working are the norm, new flexi-job apprenticeship agencies will bridge the gap to help employers realise the benefits of apprenticeships for their business.

According to the Education and Skills Funding Agency: “We are inviting sector bodies, groups of employers and other interested organisations to register as flexi-job apprenticeship agencies, giving them access to the £7m fund to support new agencies with their start-up costs.”

Prospective agencies need to be able to demonstrate that they understand the skills needs of their sector or region, can work towards financial sustainability in the coming years.

“Flexi-job apprenticeships put apprentices in the driving seat and enable them to complete their apprenticeship across multiple short employment contracts,” says Kevin Wellman, chief executive officer of the CIPHE. “This seems to be even more likely now that the government has invited providers to submit an ‘Expression of Interest’ to engage in the pilot to test this new model of apprenticeship delivery and support developments in the apprenticeship programme.”

ADVICE ON HOT WATER S TOR AG E FOR LOW TEMPER ATURE HE ATING SOURCES

Matching domestic hot water storage capacity to new technologies can be difficult

T

he CIPHE has been working closely with the industry for the last two years looking at the future of domestic hot water storage design to ensure that the transition from high-temperature to low-temperature heat sources has consumers at its heart.

The industry has been cautiously hanging its hat on the old BS 6700 method for sizing hot water storage for many years and has not fully recognised its limitation when applied to current technology. In the

34 P&H ENGINEERING | QUARTER ONE | 2022

early part of 2022, the CIPHE will be reconvening its Technical Working Group in Hot and Cold Water Services to tackle the current confusion surrounding hot water storage design. The following is a list of some comparisons between the two standards: BS 8558 This standard utilises the old simplified BS 6700 formula for calculating both the usable volume of hot water within a

always consult the manufacturer for test and performance data.

Understanding the basics of usable hot water in a cylinder Using a simplified version of the equation stated in BS EN 12831 part 3 2017 that calculates an amount of usable energy in the cylinder, you can see the amount of available mixed point of use hot water at 40°C for a cylinder stored at 60°C from the tables in figure 3.

cylinder and reheat times. This method does not realistically account for the effects of water mixing within the cylinder as the cylinder is being discharged/charged, as turbulence occurs when the cold water mixes with the hot water, reducing the temperature of the DHW as it leaves the cylinder during draw-off periods over time.

Additionally, this standard does not account for the effects of lower heat generator flow temperatures and how this affects the cylinder coil effectiveness/heat input during the reheat phase. In a mixed storage cylinder with an internal coil, the full heat output of the coil is achieved when the water surrounding the coil is at its coldest, for example 10°C. The greater the difference between the heat generator flow temperature within the coil and the surrounding stored water, the greater the power available through heat exchange.

Figure 1 illustrates the effect of lowering the flow temperature in a mixed storage system from 65°C to 55°C. BS EN 12831 Part 3 2017 • Makes allowance for the incoming water to mix during the charging phase.

• All calculations are based upon an

CIPHE.ORG.UK

energy balance equation and calculated on a minute-by-minute basis. The energy equation allows for various factors such as cylinder heat loss and variable DHW draw off over time.

• This standard reduces the available water that can be drawn from the cylinder before the temperature falls below a usable minimum capacity.

• There is also a calculation for the effects of heat transfer where the power is reduced as the water approaches its final storage temperature. Full heat generator power is not applied to the cylinder coil throughout the cylinder reheat phase for mixed storage systems.

• There is a differentiation between the available power during the reheat phase between a charged hot water system versus a mixed hot water cylinder.

Figure 2 illustrates both a direct charged and mixed hot water storage cylinder.

The direct charged hot water system allows for full power during reheat, whereas the available power in the mixed hot water storage cylinder suffers a drop in available power as the temperature of the water surrounding the cylinder rises.

Note: heat exchanger design varies for different manufacturers with different coil locations and types, so you should

How does this relate to customers’ hot water usage?

The obvious key factor for correctly sizing a hot water cylinder is to ensure there is enough usable stored hot water available to deal with the peak demand

from the household, and with sufficient power available to reheat the cylinder during periods of disuse.

The key challenges with the future of hot water design are tackling the lower power and flow temperatures available from heat generators such as heat pumps. Installers should always consult manufacturers as there is a wide variety of different technologies on the market to help deal with the challenges of low power and flow temperatures. Figure 4 illustrates a 24-hour consumer hot water profile of 225 litres at a mixed outlet point of use of 40°C throughout the day, with a peak evening usage of 130 litres. In the profile in figure 4 there is a small amount of usage between the morning and afternoon, so it would be wise to always leave some additional capacity within the cylinder for small draw-offs such as the kitchen sink and basins. In the event of a property with high usage throughout the day, then the reheat time becomes important between periods of disuse, so the sizing of the cylinder becomes even more critical.

Selecting a suitable cylinder Referring to both the table in figure 3, the simple energy equation derived from the amount of usable energy between 40°C and 60°C, there is the

The MCS HW cylinder selection guide also gives the installer a useful table to help aid the cylinder selection (figure 5) based upon the number of rooms and bathrooms. However, the guide also encourages the installer to consult the cylinder manufacturer to ensure the heat exchanger/coil is sized sufficiently for lower flow temperatures and higher flow rates. Considering the

36 P&H ENGINEERING | QUARTER ONE | 2022

previous example of a four-bedroom property, with a bath and en suite, the MCS table recommends a minimum of a 250 litre cylinder for a 3kW to a 6kW heat generator.

PIPEWORK

Incorrect use of flux exacerbates the problem of 'blue water'

J E R RY W H I T E L E Y CIPHE technical manager Jerry has worked as a self-employed installer and also has experience teaching. He advises on technical issues and compliance jerryw@ciphe.org.uk

Dealing with the blues Blue water is something that shouldn’t be ignored, says Jerry Whiteley

T

he term blue water is used to describe the pale blue/green discolouration of water that consumers sometimes experience when running their taps or see in the form of similarly-coloured stains on sanitary ware. However, this is not to be confused with the relatively recent incidents involving ‘loo blue’ being siphoned from WC cisterns and being drawn primarily from kitchen taps.

How does this happen?

Research shows that when some newly-installed plumbing systems haven’t been used, but have been left with water within the pipes, the internal bore of the copper pipes can corrode and may start to turn the water blue.

This happened in the first lockdown for

38 P&H ENGINEERING | QUARTER ONE | 2022

some who left systems on test.

The other thing that can corrode copper is excessive use of flux, so using the correct type of flux with lead-free solder is important. The older types of fluxes that are based on petroleum jelly tend to solidify within the pipe after the soldering process and don’t tend to be flushed out with cold water alone. They also tend to produce carbon, which when left inside the pipes becomes corrosive. Therefore, making a soldered joint correctly is an important process, not just to be water tight, but to avoid corrosion at a later date.

It’s important to not flux inside the joint, only the outside of the pipe. This is because after you have brightened up the ends and inside of the fitting (use scouring pads and not wire wool as this

CIPHE.ORG.UK

B LU E WAT ER | T H E F I X

Useful information

Green speckles are evidence of corrosion

leaves metal particles behind), when the joint is pushed back together the excess flux slides back along the joint and won’t ooze inside the pipe.

Blockages Where flux can’t be washed out, for instance within a gas supply, any excess flux actually becomes a restriction or blockage. In cold water, the excess flux may block the tap and other filters or the

orifice within the float valves, which just makes the commissioning a lot harder to get rid of it. This might lead to the system requiring chlorination, which isn’t something a lot of people are suitably qualified to do, and more expense.

If a system is not going to be used, for example if the occupiers are not ready to move in or may be away for some time, then draining down the system will help stop the corrosion of the copper. This is

Update: Boiling water and filter taps The following is an addition to the article on boiling taps/ three way taps in the Q4 issue of P & H Engineering magazine: These taps have become very popular through consumer demand, but greater clarity is required for installers before they attempt to install a three-way or boiling water tap.

• Installers should inspect and check that any tap or terminal fitting is compliant before installing, regardless of who purchased it.

• It must be compliant with all regulations and in particular, the Water Regulations or Building Regulations, where applicable, or any other.

• Check to see that the

CIPHE.ORG.UK

product is listed for WRAS Approval, KIWA, NCF. • Water must not be stored above boiling point (100°C) according to part G3 of the Building Regulations. Check the manufacturers’ information on their storage vessel temperatures.

• Those that have a discharge or vent pipe/tundish that creates an air break, might demonstrate the discharge into the adjacent waste pipe, treat this the same way as a D2 pipe, in that the waste pipe is suitable to accept very high temperatures, and replace if necessary.

• A dripping tap (wasting water) is not allowed, this may create confusion

between a faulty tap and expansion of water. The installer and consumer need to be aware that expansion water must be permitted to discharge for the safe operation of the water heater.

The installer should explain to their customer why their tap may occasionally appear to drip and not force or damage the operation of this specific tap requirement, when checked over. Other and probably more expensive taps use a vent pipe into a waste pipe, as described in point 5. The price may still not make it compliant.

• Always thoroughly read the manufacturer’s instructions; these are often found online.

• On the Water Regulations UK website, under Publications, installers can find the Water Industry Approved Installation Methods specifically relating to solders and fluxes (WRAS 9-04-02 Use of solders and fluxes).

• Make sure you have good ventilation from the fumes as they are known to be causes of lung cancer. See the latest update from the HSE on welding fumes/COSHH regulations: www.hse.gov.uk/welding/ protect-your-workers/index.htm • Soluble fluxes will be flushed out as part of the commissioning process. Again, the Water Regulations UK website information leaflets set out some excellent information on commissioning plumbing systems (9-05-01 Commissioning plumbing system).

even more important in soft water areas as the water is more corrosive than those in hard water areas.

Softened water has been known to cause pitting in some cases and corrodes copper tube. It’s not unusual to find green speckles on the outside of the tube. Don’t wipe these off, as the pipe will almost certainly start to leak.

The green speckles are pitting from corrosion. If this is visible then the system is badly corroded and will need replacing as it won’t be in just one place.

You should read the labels on the side of the flux you purchase to ensure you are using the correct type. Cleaning off the joints afterwards is very important as the residue is corrosive. Residue can lead to joint failures some time down the line.

A

t Welsh Water, our vision is to earn the trust of our customers every day by delivering high quality, essential services that protect our customers, their communities and the environment. One of the many ways we earn that trust is by ensuring that plumbing installations that we supply comply with The Water Supply (Water Fittings) Regulations 1999, whether that be changes to their existing supplies or the installation of a new supply.

The Water Fittings Regulations apply to all plumbing systems, installations, water fittings and equipment that is supplied from the public water supply and applies to systems in all types of premises. We have a duty to enforce these regulations on behalf of the Welsh Government and DEFRA, which means we can also be audited by the Drinking Water Inspectorate (DWI) to ensure we are enforcing correctly.

One way of ensuring compliance is using suitably qualified and experienced professionals when carrying out any works. We actively support the WaterSafe scheme and promote the

CIPHE.ORG.UK

use of its members to all our customers. We want to ensure our customers have access to suitably qualified and experienced local plumbers who have knowledge of the regulations.

Plumbers have told us that one of the biggest challenges in joining WaterSafe is having the recognised Water Regulations training. To help with this, here at Welsh Water, we have developed a one-day training course to help qualified plumbers obtain a qualification in Water Supply (Water Fittings) Regulations 1999.

In having this training, plumbers can then sign up to WaterSafe free of charge through the Chartered Institute of Plumbing and Heating Engineering.

As a CIPHE Registered Plumber (RP) it has never been easier for plumbers to join WaterSafe.

Membership is free for CIPHE members with the necessary qualifications, so all you have to do is complete the CIPHE/ WaterSafe registration form available here: www.ciphe. org.uk/ globalassets/. application-forms/ ciphe_watersafe_2fill _v4.pdf

If you hold a plumbing qualification but are missing this specific qualification, Welsh Water can offer you our one-day training package completely free of charge!

As part of the training, we’ll help with getting you signed up as a WaterSafe plumber by guiding you through the paperwork.

Once you have the WaterSafe stamp of approval, you will benefit from free promotion in your local area from Welsh Water as well as access to free guidance and advice.

If you’re interested in signing up for the one-day training, please complete the expression of interest form available here: www.dwrcymru.com/en/ help-advicewaterregulations/ watersafe -plumbers Alternatively, for more information on the training we offer or details on the benefits of the WaterSafe scheme, you can contact us at water regulations@ dwrcymru.com

IPHE-HKB’s chairlady, Sylvia Liu, has plenty of industry experience and relishes the challenge of her new position.

Her 20 years of expertise in the field of system design in building service consultation and project management for plumbing, drainage and swimming pool filtration installations has provided her with invaluable experience in the industry.

Not only is Sylvia experienced at carrying out administrative and supervisory work on these types of installations, which include residential buildings, commercial buildings, hotels and parks, but she has also led the project team for coordination on development of works programmes, procurement scheduling and construction methodology, as well as management and engineering exercises.

44 P&H ENGINEERING | QUARTER ONE | 2022

Problem solver As a school girl, Sylvia was always very interested in mathematics and physics, enjoying the problem solving elements and providing the solutions to them.

Therefore her chosen career in engineering was a logical progression.

“Engineers get to solve problems, design things that matter and improve quality of life, so I never get bored,” says Sylvia. “In engineering, you are always challenged to look for the best way to do things in less time and at a lower cost. As an engineer, we have to stay up-to-date with all types of technology and industry knowledge and this continuous learning makes life very interesting.”

According to Sylvia, her background in the plumbing and drainage engineering industry is beneficial to her current role and she believes that the

CIPHE.ORG.UK

H O N G KO N G

field of engineering offers more career choices than any other discipline.

“I am very lucky to join a company which offers guidance to team colleagues,” she says. “I have a good understanding of plumbing and drainage and my knowledge of design will enable me to prepare, handle and face on-the-job challenges.”

Taking responsibility Sylvia believes that the responsibility of a plumbing engineer does not end with the design, but covers supervision of these systems, from water supply to sewage treatment.

“We take care of the water supply, sewage and waste water and make sure that clean water is available to citizens,” she explains. “We can see engineering everywhere in the world around us, improving the ways we work, communicate, stay healthy and entertain.”

Plumbing systems convey fluids for a wide range of applications and as such the infrastructure is critical to public health and sanitation. For example, to ensure quality drinking water, the right design and control measures are vital.

“Our plumbing engineers should always ensure the safety of our water,” asserts Sylvia. “Prevention of failure is far cheaper and safer than letting equipment or systems fail.

Condition-based maintenance assumes that the failure is age related and a clear service life can be determined. When you implement a regular maintenance process effectively you should be able to reduce the risk to systems in the most economical way. So, in my view, a well planned maintenance programme is highly efficient.”

iu-Chung Yiu has over 30 years of experience in the design, project management and construction of building services. He is also extremely knowledgeable about the codes and regulations of Hong Kong, Macau and PRC authorities and utilities, making him a useful asset at the branch.

Background After working in MEP Consultant Firm as an engineering design and project management specialist for over 25 years, a friend suggested to Yiu-Chung a change of career to a contractor.

“After some thought I eventually moved out of my comfort zone and became a contractor,” recalls Yiu-Chung. “Being a part of the plumbing and drainage industry as a contractor, overseeing a team of managers, engineers, supervisors, sub-contractors and workers, is challenging. Every day is full of surprises and I utilise my skillset to tackle them.

“The most interesting project I have worked on was designing the plumbing and drainage system of the new waterpark in Hong Kong called Ocean Park. The unique building forms, changing geography and complexity in building usages escalated the challenges to a new level.”

Water safety The pandemic has brought greater focus on safety measures and when it comes to water, the right design

“The drinking-water supply must be protected from cross-connections with unsafe sources” appropriate control measures are vital, says Yiu-Chung: “Plumbing systems should not be permitted to endanger water safety in any way. The drinking-water supply must be protected from cross-connections with unsafe sources or with waste water plumbing systems.

It must be able to cope with the hazards of back pressure or back siphonage, and the water should not be in contact with plumbing materials that might impart contamination.

“It has been reported that the Hong Kong Building Department will introduce legislative amendments in respect of the design of drainage pipes in newly constructed buildings, including requiring floor u-shaped water traps to adopt a design that will prevent them from drying up, and the use of different main drainage for units on upper and lower floors, to reduce the risks of cross infection of diseases.”

WELLBEING | SUPPORT The Help Inside the Hard Hat campaign is raising awareness around mental wellbeing in the construction industry

Hard times Mental health issues are on the increase, so it’s important to know the signs to look out for and where to get help

M

ental health has been hit hard following the COVID-19 pandemic, with two construction workers taking their own lives every working day, according to the HSE. It’s a sad fact that people who work in this industry are three times more likely to take their own life than in other sectors.

There is a misconception that people who work in manual jobs are tough, both mentally and physically. However, according to research by the Lighthouse Construction Industry Charity, which deals first hand with the results of not addressing issues that are happening ‘inside the hard hat’ (HITHH), this simply isn’t the case.

Take notice The pandemic has had a significant impact on the industry, as over 53% of the working population in the construction industry are self-employed, agency workers or on zero-hour contracts, so work has the potential to drop off fast.

A survey commissioned by the charity with Glasgow Caledonian showed an increase in suicide in construction from 2015 to 2019. As a result the charity launched its HITHH campaign, aimed at everyone in the industry, to raise awareness of mental wellbeing issues.

“We need more companies to engage with, accelerate and amplify our efforts to improve our workforce’s wellbeing,”

“It’s not always obvious that someone is struggling – look out for changes”

says Bill Hill, chief executive officer of the Lighthouse Construction Industry Charity, which partnered with the CIPHE’s Under Pressure mental health campaign in 2019. “With over 500 suicides every year in construction, we are all morally obligated to be on the lookout for individuals who are struggling.

“It’s not always obvious that someone is struggling, but the key is to look out for change. If a person is normally cheery and then, over time, they seem quiet and withdrawn, ask if they are okay. Always ask twice. It’s so easy to say you are okay to someone when you’re not, so ask again, make eye contact and wait for the answer.”

Speak out Whether you’re struggling with mental health issues yourself or you suspect a colleague or employee may be struggling, there is plenty of support available.

The Lighthouse Construction Industry Charity has a large portfolio of free resources and training, including a 24/7 confidential helpline, a self-help app and online interactive wellbeing masterclasses.

It also offers hour-long interactive wellbeing sessions and a two-day MHFA England approved Mental Health First Aider course. The sessions are based around workplace wellbeing issues and topics include: stress management, building resilience, work-life balance, mindfulness and an introduction to meditation.

“A crucial element of our strategy is to proactively support the industry’s mental wellbeing and ensure the widespread availability of construction-focused training programmes,” says Bill.

“Anyone in crisis can help themselves with the app, call us on the helpline or talk to somebody on site – they should never be alone. We want to deliver a message of hope and reassure our construction community that ‘we’ve got their back’ and that we’re working tirelessly to ensure that no construction worker or their family is alone in a crisis.

“This isn’t an easy subject to tackle, but by helping to remove the stigma about mental wellbeing we can encourage people to start a conversation. This simple action could make all the difference to someone and could even save a life.”

Bill Hill, CEO of the Lighthouse Construction Industry Charity
