The importance of grease management systems

CLIMATE CONTROL Systems to regulate indoor temperatures

Welcome

HIGH HOPES FOR the government’s Green Day announcements were met with frustration and disappointment from the plumbing and heating industry, which largely criticised the lack of ambition and clear timescales. However, the Eco Levy, £30m Heat Pump Investment Accelerator Competition, and the £5 million Heat Training Grant are all good news for the industry.

Updates to Part L Building Regs come into force in June, so it’s vital that members are familiar with the regulations. We assess the changes that will impact installers’ work. (p28)

As average summer temperatures increase due to global warming, we explore the di erent cooling systems available to make indoor spaces more comfortable in the heat. (p18)

With blockages becoming more frequent, we look at the essential role of grease management systems in keeping drains and sewers clear and protecting the environment. (p32)

KEVIN WELLMAN

THANK YOU TO THOSE members who provided observations on the recent government consultation, Improving Boiler Standards and E ciency. While much of the consultation was specific to manufacturers, it did address whether lowtemperature heating system training should be mandatory for gas-boiler installers to help ensure building regulations are met. I was encouraged by this as I have been calling for mandated CPD for a long time.

The skills issues I have reported on in recent years are not restricted to the UK. In March, I attended the general meeting of the World Plumbing Council where I asked the question, should CPD for plumbing and heating be mandatory? The response in support was unanimous. Countries around the world recognise the importance of quality education and training to help safeguard the health, wellbeing and safety of the public, and it is time that the UK did so, too.

I am greatly encouraged by the high number of members and installers who have completed the CIPHE/LCL Awards Low Temperature Heating and Hot Water Systems in Dwellings qualification. Find one of many

The CIPHE has seen an increase in membership, including among Approved Training Centres and Trainees.

New grant for heat pump training

More than £14m is being made available to accelerate the installation of heat pumps and heat networks, as a new scheme launches to train installers.

Over £9.7 million will go towards four projects across the country, helping cut costs of these low-carbon technologies.

‘Green Day’ announcements

A

the need for more information to be provided to installers about heat pumps

THE GOVERNMENT ANNOUNCED its latest energy policies at the end of March. The Energy Security Plan, which builds on last year’s Energy Security Strategy, includes:

• An extension of the ECO levy, which funds improvements to the energy efficiency of social and low-income homes

• A new £30m heat pump investment accelerator scheme

• An extension to the boiler upgrade scheme to 2028

• A list of the first government-backed renewable hydrogen projects

Henk Van den Berg, strategic business manager, heating & renewables at Daikin UK commented:

“While it’s reassuring to see the government taking steps to get the UK onto the path to net zero, the latest announcements are missing a clear timescale for the important shift of the Climate Change Levy away from electricity.

“The government continues to split the

nation’s focus on renewable heating in the home and in business, with further investment in hydrogen, which lacks the technology and infrastructure to make a meaningful and immediate impact. Couple this with not bringing forward a ban on fossil fuel boilers in UK homes, and the government is missing a huge opportunity to decarbonise homes in the short to medium term.

“Extending the Boiler Upgrade Scheme to 2028 is a positive step, but there’s a real need for transition technologies such as hybrid heat pumps to be brought into the fold. These can be retrofitted into UK homes quickly and easily, allowing homeowners to take a first step into renewable heating, and have already been successful in transitioning homes to greener forms of heating in other European nations. People need to be convinced they will save money by replacing fossil fuel with renewable energy. Without all of this, Powering Up Britain will not happen at the pace that is needed for our economy and our environment.”

And over the next two years, a total of £5m will be available to support 10,000 plumbing and heating engineers in England upskill to become accredited heat pump installers. Each person will be eligible for a training grant of up to £500.

Neil Collishaw, CEO at BPEC – an industry leading provider of qualifications – said: “We’re excited about this new training grant initiative and have been working closely with the government, providing advice and guidance to ensure any grants offered benefit those working in the plumbing and heating industry.

“All BPEC’s heat pump qualifications have been included in the list of approved courses and we will be promoting this initiative to all our centres that offer training across England.”

Training providers will need to apply to offer the grant.

Daikin’s Henk Van den Berg

survey has highlighted

Poor awareness led to boiler scheme failure

A SIGNIFICANT LACK of publicity contributed to the government’s failed Boiler Upgrade Scheme, data from The Eco Experts has revealed.

The Renewable Energy Authority collected Google Trends data that highlighted consumer interest in ‘air source heat pumps’ over the past 12 months, but minimal searches for the ‘boiler upgrade scheme’ or ‘heat pump grant’.

The search data highlights a clear consumer interest in ‘air source heat pumps’ last year, with UK searches reaching 100 between 11 and 17 December. However, searches for ‘boiler upgrade scheme’ during 2022 were significantly low, with just 15 from 3 to 9 April. The term ‘heat pump grant’ also experienced a low search volume in 2022, with a search score of just 28 from 27 March to 2 April.

The UK government launched its Boiler Upgrade Scheme in May 2022 to help households cut the cost of their energy bills and help Britain achieve its net-zero ambitions. However, in the

TECHNOLOGY

first five months the scheme only achieved 33% of the heat pump installations needed to reach its overall target. In fact, data from the Microgeneration Certification Scheme shows that the number of heat pump installations has decreased since the scheme was introduced.

The Eco Experts writer and researcher Josh Jackman commented: “The government has failed the public and the planet by refusing to publicise its own Boiler Upgrade Scheme in a year when consumer interest around air source heat pumps has reached peak popularity. This new data highlights the government’s two-faced approach to its climate targets: introduce a grant to tick a box, then neglect it completely.

“After ending the Plug-in Grant and Domestic Renewable Heat Incentive in 2022, this deliberate abandonment of the Boiler Upgrade Scheme takes the government’s record on providing UK households with energy-saving and a ordable technology to a new low.”

UK first: heat pump village

The first resident in the Cornish village of Stithians has had their ground source heat pump (GSHP) connected to an ambient heat network that will draw energy from under the street. It’s thought to be a world first shared ground array being retrospectively installed in a public highway.

New data boosts heat pumps support

Air source heat pumps can operate with high e ciencies, even in cold weather conditions, according to interim heat pump performance data released as part of the Electrification of Heat Demonstration Project (EoH).

Funded by the Department for Energy Security and Net Zero, the EoH is working to understand the feasibility and constraints of a mass rollout of heat pumps in Britain. A total of 742 heat pumps were installed into a broad spectrum of housing types and ages. These heat pumps are being monitored throughout the trial to assess their performance.

The interim data and results of this monitoring, conducted between November 2020 and August 2022, have been released by Energy Systems Catapult, the net zero innovation centre appointed to lead the management contractor consortium. Its homes business leader, Marc Brown, said: “The findings highlight how far the industry has come in innovating to improve the performance and e ciency of heat pumps.”

The pioneering project, Heat the Streets, is run by Kensa Utilities and part funded by the European Regional Development Fund. It represents a significant investment in the future of sustainable energy.

The infrastructure emulates the existing gas grid and has been designed to accommodate future connections, allowing

households who were not ready to change their heating system to connect at a later date.

Wouter Thijssen, managing director of Kensa Utilities, said: “It’s fantastic to have the first heat pump up and running on this landmark project, which provides a blueprint for the decarbonisation of heating in the UK.”

But he warned there was no room for complacency. “Government and industry should commit to upskilling installers in low-carbon heating solutions.”

Decarbonisation guide for social housing

Social housing providers are being advised to start planning a phased approach to heat decarbonisation across their building stock in a new guide from Baxi: Decarbonisation and A ordability of Heat - A Phased Approach.

The free, downloadable guide gives social housing providers a framework for achieving net zero, particularly in harder-to-decarbonise social homes.

With many residents struggling with fuel bills, social housing providers face the dual challenge of solving fuel poverty while achieving their own environmental targets. Baxi’s guide recognises that only a comprehensive mix of technologies, implemented at scale within suitably prepared housing stock, will be able to face up to the net-zero challenge, while maintaining maximum comfort and minimum disruption for residents.

Warning over non-compliant pumps

Pump industry leaders are calling on the government to clamp down on non-compliant central heating pumps being imported into the UK.

The appeal is being driven by increasing concerns that exporters from the Far East have penetrated the traditional merchant distribution channels to target the UK, with more than 100,000 non-compliant pumps being sold in the UK every year.

Steve Schofield, chief executive of the British Pump Manufacturers Association (BPMA), said: “We estimate that circa 10% of the 1 million central heating pumps, technically known

The four-phase plan encourages social housing providers to take a fabric-first approach within harder-to-heat homes to ensure that the buildings are as e cient as possible and suitable for the low-temperature heating prescribed by Part L of the building regulations. As a next step, housing providers are urged to consider accessories that will improve the energy rating of existing systems before planning larger-scale investments, such as air source heat pumps and heat networks, or longer-term solutions such as hydrogen boilers.

David Cook, residential sales and specification director, said: “With Baxi’s

expertise and support, social housing providers can prepare better by being well informed. This guide is the starting point of the net-zero journey and, by partnering with Baxi, social housing providers can be assured of a smooth transition to energy-e cient, low-carbon heat that will tick all the sustainability boxes.”

as circulators, being brought into the UK are non-compliant. It is a swarm; it is blatant and it is now over the counter. Once fitted, they are costing consumers hundreds of pounds every year on their heating bills, and it is seriously impacting the UK’s ability to meet its net zero obligations.”

Non-compliant pumps that Wilo experts have seen are being manufactured to look like genuine OEM pumps, even sometimes

Schofield added: “We have been very lax in the UK in terms of policing the market and eradicating noncompliant pumps. European countries have much stricter regulatory policing regimes and are not being targeted in the same way. It is the legal responsibility of the importer to ensure that only compliant pumps are brought into the UK. However, it is the distributor’s responsibility to only sell CE-marked pumps and the installer’s responsibility to ensure that what they are fitting is compliant. We need the government to step in, empower the market surveillance authorities and clamp down to protect consumers and its own climate change targets.”

PARTNERSHIPS

Building regulations change support

Polypipe Building Products has launched a campaign to support heating installers through the updates to building regulations as the grace period draws to a close on 15 June.

The campaign, which will run throughout 2023, has been created in partnership with installers Stanley Tabersham, Fiona Evans and Robert Clarke. It kicks o with the launch of a new game show, A Question of Regs, and will include regional events and educational activities to o er installers support through the transition period.

Dan Love, head of commercial at Polypipe Building Products, said: “Last year England, Wales and Scotland introduced the biggest set of building

DRAINAGE

THE CHARTERED INSTITUTION of Water and Environmental Management (CIWEM) has welcomed the government’s announcement to implement Schedule 3 of the Flood and Water Management Act 2010, which will mandate sustainable drainage (SuDS) in new developments.

SuDS use nature-based approaches to slow, store or filter rainwater that may otherwise overwhelm sewers. Unlike a pipe, SuDS o er benefits including managing flash flood risk, filtering and cleaning contaminated water, increasing nature habitat, helping to mitigate the e ect of heatwaves, recharging water resources and improving local air quality.

The CIWEM says these benefits will only be felt if SuDS are built in the right way, hence the need for approved standards.

It says: “Over the past decade, outmoded thinking has cast SuDS as

regulation updates to impact the heating sector in over a decade. Now, almost a year down the line, heating engineers need to ensure that they are familiar with the changes. That’s why our team has introduced this multi-faceted campaign to support installers as this grace period draws to a close.”

Daikin helps Manchester to

reach net-zero

Low-carbon heating specialist Daikin has signed an agreement with Greater Manchester Combined Authority (GMCA) in a first-of-its-kind public and private joint approach to decarbonisation.

Daikin and GMCA have been working together for more than 10 years towards Manchester’s target of becoming carbon neutral by 2038. The partnership will give GMCA a purchasing framework to deliver Daikin heat pumps for social housing across the city by 2025, making the procurement process more straightforward.

complex and expensive and a barrier to rapidly increasing the supply of housing in England. A non-statutory approach to encouraging SuDS through the planning system, introduced in 2014, failed to unlock their potential. Now, with flash flood risk increasing and sewage pollution widespread, the mandatory approach set out in Schedule 3 is long-overdue.

“Schedule 3 will also ensure that builders’ automatic right to connect new development into existing drainage networks is made conditional, requiring SuDS potential of a site to be delivered first. It will additionally provide a mechanism for ensuring SuDS structures will be maintained in the long term so they continue to function e ectively.”

The installation of the heat pumps will be a key part of GMCA’s Social Housing Decarbonisation Fund, which will see up to 1,000 heat pumps delivered to social housing across Greater Manchester.

Hiroyasu Ishikawa, managing director of Daikin UK, said: “Other cities should look at this relationship as a bestpractice approach to meeting decarbonisation targets in social housing.”

SuDs mandate for new developments

Worcester Bosch launches HVO kit

WORCESTER BOSCH WILL be launching HVO (hydrogenated vegetable oil) Conversion Kits for its Heatslave and Danesmoor oil-fired boiler ranges later this year.

The kits will enable homeowners to significantly reduce the carbon output of their existing heating system without the need of moving to an alternative technology, which can be costly and disruptive.

Martyn Bridges, Worcester Bosch director of technical services, said; “We believe the road to net zero requires a technology-agnostic approach to ensure all homeowners have options when it comes to reducing their carbon output.

Although availability of HVO and other biofuels remains limited in the UK today, we strongly believe that this will improve significantly in the next few years.”

Lincolnshire branch event

The CIPHE Lincolnshire branch recently held its 76th annual dinner awards, sponsored by Aqualisa, Pegler-Aalberts, Ramboll and Chameleon Print.

Winners of the Student of the Year Awards were Deniss Lavrentjevs (above, left) from Holbeach College and Martin Burnham from Lincoln College.

The awards included a framed certificate, a trophy and a goodie bag.

SAFETY Grenfell report delayed to 2024

The final part of the Grenfell Inquiry report is now not expected to be published until next year. The first part of the report was published in October 2019 but the second part, which will focus on the refurbishment of the tower, will take longer than expected to finish. The inquiry team said: “It is important that, as what we hope will be regarded as the definitive version of events, the report is complete and accurate.”

Selco champions women in industry developments

Selco Builders Warehouse has launched a new women’s forum to help highlight and encourage the ongoing career progression of females in the company.

The opening meeting was held on International Women’s Day in Coventry.

Sally Kerr, Selco’s head of HR operations, who is chairing the new group, said: “We’ve made important progress in recent years

and are proud that 90% of the current managers and deputy managers who are female have come through internal promotion.

“We want to lay out a programme that encourages other females to follow suit and move through the ranks. There is no better way to get feedback on that than by speaking to the people who have already achieved that progression.”

INDUSTRY

New premises for Altecnic

Altecnic, supplier of plumbing, heating and solar products, has acquired an additional warehouse and distribution premises in Sta ord. This will allow Altecnic to further expand its stockholding, scale assembly operations and develop a dedicated training centre.

UWLA calls for more education

The Unified Water Label Association (UWLA) is calling for an integrated approach to education and promoting the ‘use water wisely’ message.

UWLA MD Yvonne Orgill says, “We must work together to support good quality plumbing, which is not only essential for cleanliness and crucial to maintain health, but important if we are to use water wisely.”

“The UWLA has been engaging with its partners to educate on the role bathroom products can play in the environmental challenge that we face. It is only by presenting a cohesive message that we can help consumers make responsible choices.”

Heat pump skills gap

THE GOVERNMENT’S TARGET for 600,000 heat pumps to be installed each year by 2028 is nowhere near being fulfilled, with installation figures last year estimated to be between 60-70,000.

According to the survey, which was conducted by Censuswide between December 2022 and January 2023 for Energy Efficiency at City Plumbing, 44% of installers don’t know where to seek training, with just 18% currently installing heat pumps and only 6% MCS certified.

A concerning 32% of installers are unaware of the government’s Boiler Upgrade Scheme in England and Wales, which offers discounts for homeowners switching to a heat pump if they use a certified installer.

Adam Foy, managing director of energy efficiency at City Plumbing, said: “As an industry we need to make training more accessible. We should be there

for installers who are interested in upskilling and encouraging others that doing so will be good for their business.

“The underlying interest is there. Our survey also revealed that 49% of installers would consider becoming MCS certified if there was a course available locally. Moreover, when we asked installers if becoming certified would be good for their careers, 82% agreed. It’s not possible to achieve government targets without trained installers, so now is the time to act.

“We need installers to be ambassadors for renewable technologies, especially in the domestic market where many homeowners are yet to be convinced, so education and effective communication is vital.”

He added, “Ultimately, net zero targets are going to be difficult to achieve without the right number of trained installers.”

Support for all trades

TradeHelp, the free network for tradespeople, has announced plans to grow its 15,000 strong network, having extended the free benefits to now support trades of all types.

Its free app, along with free desktop log-in, offers tools enabling trades to manage their businesses from anywhere.

A survey has highlighted the urgent need for more information to be provided to installers about heat pumps to inspire them to seek training and address concerns

MIKE MASKREY is a third-generation plumber who has a great deal of experience both on the tools and within the education and training sectors. With a grandfather, father and uncle all in the plumbing and heating profession, it seems that Mike was destined to be in the industry. Going out on jobs with his father, Eric, when he was a young child sparked an interest that has lasted decades. His son, Joseph, has even joined the ranks, completing his Level 2 in plumbing in 2010.

“Plumbing is in my family’s blood,” says Mike, “Dad’s view of the industry greatly influenced my career path. He was a big advocate of the Institute of Plumbing, as it was known then, and he was the Nottingham Branch Chairman for two years.”

Early years

In 1977, at the age of 16, Mike joined Hiltons, a well-respected Nottingham-based fi rm, as an apprentice plumber. He also attended Basford College in Nottingham on block release and then one day and one night per week. He worked mostly on large industrial works, for companies such as Boots, British Home Stores and M&S, installing hot and cold water, boosted water and sanitation systems.

“My dad’s influence was always there,” says Mike. “On my first day at college, a lecturer called Walter Holt came into the classroom and took the register, he asked if I was any relation to Eric Maskrey and I said yes. It turned out that he had taught my dad. This is how it went for fi ve years at college; I could not escape my dad’s reputation.”

Mike spent fi ve happy years at Hiltons, learning his trade and gaining valuable experience. Everything was going well, so he bought his first house in December 1981 and was also looking forward to his wedding the following year. However, a spanner was put in the works when he was made redundant in early 1982.

“My dad told me not to worry and that he would take me on,” recalls Mike. “It was one hell of a risk for him as I was an industrially-trained plumber and his company dealt with domestic plumbing. I had

to learn my trade all over again. I was with my dad for 17 years. He was a feisty character, and a cracking, much respected plumber and I miss his counsel now. I would love to be able to tell him what I am up to.”

Branching out

In 1988, Mike took a part time job at Basford College in Nottingham, teaching heating and ventilation for two years, before transferring to the plumbing department. He worked alongside teachers who had taught him the trade.

“I had been teaching at the college for 13 years when my dad told me he was going to retire to look after mum, Audrey, who had Alzheimer’s disease,” says Mike. “Dad offered me his business, but I didn’t want to be a business owner, I wanted to be a plumber.”

Mike moved to Stockport in 2000 and worked as a plumber for a company called Mycocks in Buxton. He worked here for a couple of years before being offered a full-time teaching position at Stockport

College. Here he taught Plumbing at Levels 2 and 3, HNC in Building Services Engineering, and Foundation Degree Level 5 in Building Services.

“My time on the tools was over,” says Mike. “I hung up my tool bag because I had seen Dad suffer terribly with arthritis, which eventually saw him registered disabled, and I didn’t want to end up the same way.”

Mike left Stockport College in 2013, but continued to teach at Doncaster college from 2013 to 2015 and then Burnley College from 2015 to 2017. During this time, he also wrote six text books for City and Guilds on Plumbing and Heating at Levels 2 and 3.

“I love the heating and plumbing industry and the books have helped me reach thousands of apprentices,” says Mike.

New opportunities

Mike joined BPEC in 2017 as a technical development manager, writing textbooks and plumbing qualifications. To date he has written the Level 3 Diploma in Plumbing and Domestic Heating, three heat pump qualifications and has overhauled solar hot water qualifications.

“I love my trade with a passion, so when the advert appeared for a position as training manager for CIPHE, I jumped at the opportunity,” enthuses Mike. “Being offered the position was like coming home.

“In my role as training manager, I will be carrying out writing and development work, and visiting colleges to promote the CIPHE. I hope to educate the installers of today in the systems of tomorrow.”

THE BIG CHILL

As the mercury rises, so too will demand for cooling systems

As the effects of global warming become more apparent in the UK, with temperatures in the summer months reaching uncomfortable levels, air conditioning and radiant cooling systems are increasingly in demand. It is therefore a subject that plumbing and heating engineers are likely to be asked about in the coming months and years.

High velocity systems

Although air conditioning systems are more common in commercial buildings in the UK, demand in residential buildings is expected to grow in the near future.

According to Unico, small duct high velocity (SDHV) systems are more likely to be considered as an alternative to conventional air conditioning systems.

“Air conditioning considerations have become so much more than simply keeping a room cool,” says Richard Soper, Unico Systems Representative. “Solutions such as SDHV technology offer a more holistic approach by offering heating, ventilation and air purification options alongside the air conditioning mode whilst also removing more humidity than a traditional air conditioning system. The added advantage of SDHV is the fact that

the system can be used during the colder months for heating, too.”

SDHV systems deliver jets of airconditioned air through room outlets, eliminating drafts and cold/hot spots in living spaces, resulting in minimal temperature variation. The flexible ducting has been designed with air handlers that isolate noise and vibration.

The air is distributed through small, flexible ducts that can fit almost anywhere in wall or ceiling cavities, between floors and around joists to make them suitable for installation in both new-build and renovated older residential or commercial

properties. Conventional air conditioning systems are unsuitable for many of these types of application.

SDHV technology can also provide heating, ventilation, air filtration or purification options that eradicate the need for costly and disruptive installation of separate systems.

“Designed for use with air and ground source heat pumps, the Unico System dispenses with the need for fossil fuel energy sources and traditional radiators,” explains Soper. “Room outlets fit seamlessly into the ceiling, wall or floor and by getting rid of radiators and pipework, available wall space can be maximised. The design of its cooling coil means the Unico System removes up to 30% more humidity than conventional air conditioning and heating systems.

“There can be a bit of a fear factor with unfamiliar technology among some installers who are used to conventional heating and air conditioning and that is fully understandable. Taking away that fear is a fundamental aim of training programmes, whether in the field of SDHV technology, heat pumps, renewables or any less familiar HVAC product.”

Direct expansion systems

There are two main types of air conditioning systems – ones that distribute cooled water, typically 6°C, using chillers in larger buildings, and the second type is direct expansion systems (DX) that offer

heating. According to Graham Wright, chair of the HEVAC Air Conditioning Group, demand for expansion systems has been steadily increasing, particularly for commercial applications, such as hotels, shops and offices.

“The domestic market has the potential to grow as our climate warms and building regulations acknowledge this with the publication of Part O (over heating in buildings) and the increasing use of heat pumps both air to water and DX,” says Wright.

Installers need to hold a Cat 1 or 2 F-gas Certificate and have the training to enable them to install DX systems. The pipework is different (albeit Copper pipework) as it uses higher pressures (30-40 Bar) and installers need experience in brazing and how to start up these systems. For the smaller systems used in the domestic market, the installation process is straightforward and is a good place to start any journey into this sector of the market.

“Installing DX type systems can look straightforward, but there are significant differences between boilers and this type of system, so training is essential,” adds Wright. “The market is expected to grow so it is worth looking at this type of work for the future. More complex chilled water and DX systems do need specific training.”

Radiant cooling systems

Another alternative to traditional airconditioning is radiant cooling, which uses cooled water, circulated through water pipes embedded in a building’s structure, to evenly absorb heat energy from a room, eliminating drafts and hot spots.

Unlike traditional air conditioning systems, that can contribute to poor air quality by distributing airborne contaminants, radiant cooling systems (RCS) can improve air quality, making them ideal for hospitals and nursing homes.

RCS use the same technology as radiant heating and achieve the best results when

Solutions such as SDHV technology offer a more holistic approach

combined with other energy efficient systems, such as heat pumps.

Radiant cooling technology, using cold water inside pipes, follows the same basic principle as radiant heating. However, it can be installed in floors, walls, or ceilings.

According to Uponor, the low operating water temperatures make this type of system the most energy-efficient method of heat distribution in buildings and therefore more cost effective. They also create better thermal comfort for the room’s occupants and provide greater freedom to architects and contractors due to the reduced need for ducts. Ceiling heating and cooling systems can also be combined with renewable energy sources to create more sustainable and energyefficient buildings.

Due to lower system temperatures in their heating modes, radiant systems are perfectly suitable for renewable energy

sources. This allows the primary energy consumption and the CO2 emissions of buildings to be reduced significantly.

Thermal Active Building Systems (TABS)

These systems use the thermal mass of a building’s concrete structure to transport heating and cooling water via pipes. Ceilings, floors and walls are used for cooling and contribute to the heating of the building, too. The inserted pipes utilise the concrete mass to store and exchange thermal energy.

The main difference between TABS and radiant cooling is that TABS use pipes which are embedded within the concrete of the building’s structure, resulting in a silent source of cooling or heating.

Uponor TABS, for example, are designed to handle the basic cooling or heating loads of the buildings, in order to maintain a constantly comfortable indoor climate. This method of heating and cooling creates a significantly improved indoor environment improving occupants’ health and work productivity.

The domestic market has potential to grow as our climate warms

According to Uponor, the system can operate in tandem with both mechanical and/or natural ventilation systems and is perfect for use with renewable energy sources making it ideally suited for modern, sustainable buildings.

In addition to improved indoor air quality, the advantages of TABS also include low maintenance and lifetime costs, financial savings during the construction phase, 30% more cost effficency in the life cycle of a building compared to conventional HVAC systems, and it’s a sustainable approach to heating and cooling.

Uponor TABS can work in conjunction with a free-hanging radiant panels cooling and heating system for quicker response in dynamic cooling and heating loads. Thermal sockets can be installed in the slab in order to enable cooling/ heating and/or peak load elements to be suspended directly from the concrete ceiling. The system has an automatic locking device, which means that additional suspended elements can be connected at a later point without having to drain the system first.

(TABS are radiant heating and cooling systems and therefore do not replace ventilation systems.)

Radiant passive chilled beam systems

These suspended cooling panels (or beams), such as the X-Wing® from Frenger Systems, provide cooling by both convection and radiation. The radiant proportion creates no air movement, the only air movement comes from the convective proportion.

As cold water passes through the chilled beam, the warm room air is cooled against the beam’s cooler surfaces. This cooled air, which is heavier due to its higher density,

then streams through the punched louvres in the radiant wings and percolates through the small ceiling perforations into the room space below (when concealed). In this way, air is circulated within the room, with warm air from the room being continually replaced by cooled air.

In addition to this convective cooling process, the cold surfaces of the beam (the radiant wings) also absorb heat radiation from the building occupants and the warmer surrounding surfaces. X-Wing’s radiant quotient is approximately 40% of the total cooling effect (the other 60% of cooling being generated by the convective cooling effect previously described). The ability of X-Wing to cool by radiation means that, when compared to a finned tube battery, X-Wing can deliver 40% more cooling without any additional risk of draft.

The efficiency of the convection process, coupled with the ability of the product to exchange energy by way of long-wave radiation, means that X-Wing retains a high cooling effect even when the air temperature in the room is relatively low (e.g. at night or when the building is unoccupied). In this way, large amounts of cold energy can be stored in the building structure during low load periods, and used to offset heat gains when the need arises.

“Our hybrid radiant cooling product, X-Wing, has had demand grow due to it being manufactured from only copper and aluminium,” explains Andrew J. Gaskell,

technical director at Frenger Systems. “At end of life it can be 100% separated without the need for specialist processes – the aluminium fins are mechanically stitched to the outside of the coil, which can be pulled apart to ensure 100% recyclability of the materials. In addition to this, the product can be installed fully exposed without the need for ceilings, which can further reduce the building’s embodied carbon.

“The X-Wing radiant cooling solution works on elevated water temperatures to function above the spatial dew point (dry coil), so can be used with free-cooling chillers or heat pumps to provide energy efficient cooling.”

The fact that the X-Wing has no moving parts means it is low maintenance and has a working life expectancy of more than 25 years, subject to water quality being maintained to suit copper.

“Due to the X-Wing’s radiant transfer, when installed with an exposed concrete soffit, it can provide direct cooling to the building’s thermal mass, which helps keep the building temperatures lower during the peak gains around midday,” adds Gaskell. “Some consultants have used thermal modelling with X-Wing / exposed mass to provide low-carbon buildings.”

As a greater focus on indoor air quality and temperature increases in the UK, it’s important that installers keep abreast of the latest cooling technology. In addition, investing in their professional development in this area will enable them to future-proof their businesses.

“At end of life, X-Wing can be separated without specialist processes”

A pipe dream

Using natural contours of the land, rather than pumps, means United Utilities can now sustainably supply West Cumbria with clean water from Thirlmere. We found out more about the new £300m network

In 2017, United Utilities began construction work on a £300m project to install new pipelines to supply drinking water from Thirlmere reservoir to people in West Cumbria. When construction started it was the largest project of its kind in the UK. The company considered desalination, along with many other

options, as part of the Water Resources Management Plan. However, this didn’t form part of the fi nal strategy because the environmental and social costs were calculated to be four times higher than the more traditional alternatives.

Prior to the construction of the new 100km pipeline, the area

received water from Ennerdale, Crummock Water and Quarry Hill. However, providing the 80,000 households and businesses in West Cumbria with water from Thirlmere reservoir is a more sustainable option.

“Ennerdale, its lake and the River Ehen are host to protected species and because of a growing population, it was decided a more sustainable source was needed and a number of options were reviewed,” explains John Hilton, project director at United Utilities.

In full flow

Today, the water is transferred along new twin 30km pipelines to a new water treatment works at Williamsgate. Great care was taken during the planning and

design phase to avoid hilly terrain, environmentally designated sites, archaeological sites and urban areas.

There are several tunnels on the pipeline route, under rivers and key road crossings. The longest tunnel section crosses under the River Greta in the Castlerigg area, with another two tunnels in Keswick and one more in the Cockermouth area. “Two pumping stations and two service reservoirs have also been built,” adds Hilton.

“The works at Williamsgate is capable of treating up to 80 million litres of high-quality water every day and features the latest technology. We’ve also installed 1,000km of cable and built fi ve tunnels on the project – which includes the largest pipe jack at the time

in the UK, to get the pipeline under Castlerigg stone circle.”

A network of new distribution pipes takes the treated water to service reservoirs where it is stored and ready

to be supplied to customers’ homes and businesses in West Cumbria.

“The COVID -19 pandemic created a number of challenges for the workforce and wider supply chain,” reveals Hilton. “As an organisation we worked with our contractors to come up with robust health and safety plans to try and minimise the risk.”

Eco benefits

The water treatment works will also be able to harness its own green energy from the force of the water arriving at the plant after it has travelled 30km from the reservoir.

“The site has a hydro turbine, which can generate 80kW of renewable hydroelectricity per hour – enough to meet 40% of the site’s needs or the equivalent of 175 homes,” explains Hilton.

The raw water pipelines have been constructed to make the most of gravity and use the natural contours of the land, allowing the water to travel easily along the pipes without the need for pumps. There are zero emissions and no pumping costs, so over the lifetime of the plant and pipeline there will be huge fi nancial benefit.

“This is a beautiful part of the world, so it was important that anything we’ve built above ground remained in keeping with the local area,” says Hilton. “Using local materials for the building

structures wherever possible was key.

“We designed the route to minimise tree loss and our plans incorporated supporting local tree-planting initiatives to create new woodlands in the area. The Cumbria Tree Fund was managed by Cumbria Woodlands and helped plant 53,000 new trees and 5,300m of new hedgerows.”

United Utilities and its contractors had to work through parts of a National Park and take into account environmentally designated sites, archaeological sites and urban areas.

“During construction, more than 400,000 tonnes of earth was moved at Williamsgate,” reveals Hilton. “The excavated earth was retained on site and has now been used to help with the landscaping of the area. The site was designed to merge into the natural shape of the surrounding environment and incorporates a living green roof to mitigate against any visual impact on the landscape.”

Positive impact

Much of the engineering equipment and local materials, such as quarried stone, concrete and cement, were sourced locally during the works. The project provided work for more than 50 Cumbrian fi rms, employing in the region of 500 people throughout the supply chain, with approximately 200

of those being local.

Working with Cumbria Community Foundation, United Utilities developed a legacy fund aimed at providing help for local people and groups impacted, or based within the area of the project. The aim was to help provide a lasting legacy and help groups to realise projects that will provide social or economic benefi ts in the community.

Lots of community and environmental groups have benefited with successful applications from the fund, from groups that o er community support and advice, to sporting and youth groups.

“The project injected over £52m into the local economy, provided placements for eight young people who were not in employment, education or training, and jobs for three apprentices,” says Hilton. “United Utilities continues to recruit local apprentices.”

As part of the government’s plans to conserve fuel and power in the UK and achieve the goal of net zero by 2050, updates to building regulations Part L were introduced in June 2022.

The grace period, which enabled work on homes with planning approval under the old regulations to proceed within 12 months of the regulations coming into force, comes to an end in June 2023. So, now’s the ideal time to revisit how the regulations will impact the plumbing and heating industry.

Quick recap

Following the consultation on the Future Homes Standard (FHS), which will come into effect in 2025, the government’s ambitious targets aim to spark a green revolution and improve the energy efficiency of new homes.

The FHS, which requires all new homes in England to produce 31% less carbon emissions and new nondomestic buildings 27% less than those previously accepted, comes into force in June. This date also applies to updates to building regulations Part L, which cover the energy performance of new and existing buildings in England and Wales.

However, under the FHS, new-build homes will be required to produce at least 75% less CO2 emissions than allowed in previous (2013) standards by 2025. So, in theory, in two years’ time, all new-build homes will be net-zero ready and will not require additional retrofitted measures in future.

THE HEAT IS ON

building regulations coming into force in June, here’s what installers need to know about conserving fuel and power

As homes are significant contributors to the UK’s carbon emissions, installers who intend to fit new boilers will be, under the updates, required to carry out a room-by-room heat loss calculation to ensure that they are correctly sized.

Calculating the potential heat loss of each room will enable installers to determine the required heat input for each area of the house, taking existing and new heat emitters into account. They can then design a system that will provide optimum temperatures and efficiency. Calculations to work out heat loss should include fabric and ventilation losses based on the difference between the indoor and outdoor temperatures.

“While this may feel like we are going back to basics, it is important to understand the purpose of a heat-loss calculation,” says Steve Ellison, assistant training manager at Grant UK. “By accurately calculating the heat loss of each room within a property, installers can determine the required heat input that the building needs. This in turn helps to identify the correct size of heat generator needed to fulfil the property’s heat demand, whether that be a heat pump or a boiler.”

L of the

Radiator requirements

The updates to Approved Document L (as it’s officially called), focus on optimising the energy efficiency of heating systems in homes, which will affect how heating is specified in new and existing homes.

With the government’s target to install 600,000 heat pumps by 2028, it’s not surprising that one of the main changes is the requirement for a maximum flow temperature of 55°C for new heating systems – 25°C less than previously acceptable.

“It is important to understand the purpose of a heat-loss calculation”

Updates to Part L focus on optimising heating systems in homes

“To achieve this much lower temperature, the heat emitters in a home will need careful consideration and radiators may need to significantly increase in size, presenting space and aesthetic issues,” remarks Dan Love, head of commercial at Polypipe Building Products. “For example, to provide 900 watts of heat output with a flow and return of 45°C/35°C, a double-panel radiator would need to be 1.8m x 0.6m, compared to 1m x 0.6m with a flow and return of 75°C/65°C. It’s almost double the size. In cases like these, installers will need to explore alternative emitters that have been designed to run at 55°C, as laid out in the new regulations.”

Although it is already a common industry practice to install thermostatic radiator valves on radiators when replacing boilers, it is now a requirement under the updates to Part L. Interestingly, it used to be a requirement pre-2006 and is welcomed back given the ease of fitting and cost e ectiveness.

Low-temperature flow

Underfloor heating is an ideal alternative to radiators, when used in conjunction with low-temperature boilers and renewable heat sources, such as heat pumps. It emits heat over a larger surface area, while running at lower temperatures – between 33°C and 55°C, rather than 75°C. The fact that underfloor heating puts significantly less demand on heating

systems than radiators means that it can perfectly accommodate the optimal coe cient of performance (COP) for heat pumps, which is attained when they run at 35°C.

In properties where there is insu cient space for larger radiators, or where the existing distribution system is provided with higher temperature heat from a low-carbon district heat network, it may not be possible to achieve flow temperatures of 55°C or below. In this instance, a new heating system will need to be designed to achieve the lowest flow temperature possible, while still meeting the heating needs of the property.

A move to smart systems

In order to minimise energy wastage, new heating systems in homes with a floor area of 150m² or greater now require a minimum of two independently controlled zones, and each heating zone requires its own smart or thermostatic controls.

“By splitting the system into zones, residents can control the levels of heat being emitted in certain areas and choose to heat only the parts of the property that are in use,” explains Love. “By turning the heating o in any room where heat is not required, less energy will be wasted.

“For traditional convectional heating, this can be satisfied through a thermostat or thermostatic radiator valves on all

Safety standards

One thing that installers need to bear in mind when working on low-temperature heating systems is the risk of Legionella bacteria forming. Systems need to be designed and installed with regular pasteurisation – heating hot water to a high temperature to kill the harmful Legionella bacteria.

Underfloor heating is highly energy e cient – particularly when run with heat pumps

heat emitters in the rooms that do not have a thermostat. For all hot water stores, a timer for heating and timer for hot water is required so that they can be controlled independently of the spaceheating circuit.”

The advantage of using an underfloor heating system is that it is designed and installed into zones and can control multiple zones at once, allowing each area – or room – to be warmed to a di erent temperature.

“It’s also worth noting that the pump now needs to automatically turn o when heat is not required,” points out Love. “Therefore, the system controls need to be wired to ensure that the heating appliance and pump can be switched o when there is no demand for heating or hot water.”

“The regulations will have a direct impact on domestic installers”

The government’s target is to intall 600,000 heat pumps by 2028

Advice for operators

BEAMA’s Building Regulations Part L

2022 – Heating Controls Guidance points out the additional legal requirement for installers to provide customers with information, within five days of work being completed, on

how to use installed building services so that they can be operated e ciently. Information on the correct use of heating and hot water controls is part of the requirement, to help occupants understand the best way to use the controls to maintain comfort and minimise energy use.

BEAMA guidance states: For both new and existing dwellings, operating and maintenance instructions should be provided with the following information on the heating controls:

• What they are and what they do

• Where they are located

• How to use them to optimise e ciency

• Any maintenance requirements

• Links to other documents such as user manuals.

The guidance also suggests that it is good practice to install a smart thermostat that incorporates either load compensation or weather compensation to ensure optimum energy savings from the heating controls.

“Although Part L contains major changes to the way heating systems are installed in new builds to gear up for the Future Homes Standard, many aspects of the new regulations will also have a large impact on how engineers design and install systems in refurbishment and retrofit projects,” says Love.

“This means that the regulations will have a direct impact on domestic installers across all projects – both new builds and existing homes – which is why it’s important for installers to familiarise themselves with the updates before the deadline.”

YOU SAY…

ALL INCLUSIVE

“Regulations need to allow for people who are not tech savvy.

It’s all very well installing a smart programmer and room thermostat to meet regulations, but if the customer cannot use it, it will never save them a penny. I work in an area with a lot of pensioners and am often asked to come back, remove the fancy electronics and fit a mechanical programmer they can actually work.”

William Wiltshire, MCIPHE

CALCULATING COSTS

“I am in great favour of increasing thermal insulation performance and reducing infiltration heat losses in all building types to reduce fossil-fuel energy consumption as long as it is economically viable to do so. The di culty is what does economically viable mean? I don’t think it should be based on current fuel costs, but I do believe that a realistic estimate of future fuel costs, compared to building life span, should be determined. To my knowledge this information is not readily available.”

Les Bassett, MCIPHE

CIPHE SAYS...

“The CIPHE wholeheartedly supports the update to Part L as it is a route to improved outcomes for consumers. However, with increased regulation compliance comes increased time and cost for installers. We will therefore continue to stress the importance of enforcement in our discussions with government. Without it, these changes are a back door for those who do not serve their customers well to undercut the practices of those who do.”

Kevin Wellman, CEO of the CIPHE

What lies beneath

Thousands of properties su er sewer flooding caused by blockages every year in the UK, creating misery for homeowners and businesses, and leading to high clean-up bills and increased insurance costs.

Blockages caused by fats, oils and grease (FOG) also have a huge detrimental impact on the environment as they can enter rainwater pipes and gullies, causing pollution in streams and rivers.

According to water industry membership body Water UK, there are approximately 366,000 sewer blockages annually, 70% of which are caused by FOG, at a cost of £100m.

An escalating issue

Fat, oil and grease are not particularly harmful when in liquid form. However, when they cool they congeal and harden, sticking to the sides of drainage pipes. This restricts the flow of wastewater and causes pipes to block.

With the increase in fast-food outlets and a change in consumer eating habits, fatbergs (large masses of fat and solid

waste that collect in a sewer system) have become increasingly common in the UK, despite legislation prohibiting foodservice outlets disposing of FOG down the drain.

Domestic properties also play a role in the amount of FOG disposed of incorrectly. According to British Water, the cost of pumping station failures and decreased e ciency of treatment works caused by FOG is reflected in water bills.

Complying with the law

When it comes to dealing with FOG, grease management systems (GMS) are essential pieces of kit for food service

outlets. Although best practice should prohibit FOG entering a drainage system, GMS will prevent any that does, potentially saving businesses a hefty fine.

The UK Water Industry Act 1991 states: ‘No person shall throw, empty or turn, or su er or permit to be thrown or emptied or to pass, into any public sewer, or into any drain or sewer communicating with a public sewer, any matter likely to injure the sewer or drain, to interfere with the free flow of its contents or to a ect prejudicially the treatment and disposal of its contents’. This is legally interpreted to include contamination by FOG.

“There are a number of di erent types of GMS on the market, with the main piece of equipment commonly being referred to as a grease trap,” explains Caroline Clark, director at CIPHE Industrial Associate,

“Grease traps must be sealed to prevent the emission of odours”

Grease management systems play an essential role in keeping drainage systems safe and clear

Aluline. “Of course, all manufacturers claim that their solution is the best, the most efficient and that it meets with all industry required standards. It is up to each owner to ensure that a correct system is installed and maintained, the relevant regulation observed, HACCP regulations and all food hygiene rules adhered to.”

However, in towns and cities across the UK, you will find many systems that do not meet all the relevant regulations. A tendency to pick and choose which regulations to adhere to has led to the units of many manufacturers being unfit for purpose.

According to regulations EN 120561:2000: ‘Drainage systems shall be

designed and installed so that health and safety of the users and occupiers of the building are not affected by, amongst other things, the penetration of toxic or noxious odours into the building. Drainage pipe work systems installed inside buildings shall not release vapours and foul air into the building’.

“Going on the above EN regulations, it seems essential that grease traps must be sealed to prevent the emission of odours, or even worse, odourless and possibly dangerous airborne toxins,” points out Clark.

What’s the solution?

To adequately deal with FOG a sealed, air-tight grease trap in the kitchen and a dosing system is an effective combination. A stainless steel, air-tight unit with baffles acts as a settlement tank, catching oil and solids at the base. A bio-hydromechanical system introduces bacteria, which degrades fat and grease overnight, to leave the drainage system flowing and odour free.

Bio film

Fats and grease deposited within the pipe work are digested by the bio film cultured from Aluzyme solution, allowing maximum efficiency of the drainage system and pipes.

Aluzyme Injection point

For Aluzyme solution ideally positioned at the point of the grease trap.

“The bio-hydro-mechanical system can be positioned inside the drain as close to any FOG source as possible,” says Clark. “This could be expensive if there is a large number of FOG-producing items. However, in new builds, if the architects or designers are well informed they will design the drainage system to have the majority of sinks on the one run. This lowers the number of traps required, reducing the cost of the GMS.

“Although, the most important component in GMS is the training of staff. If not informed or trained in how to look after drainage it will not matter what equipment is fitted, problems will undoubtedly happen,” concludes Clark.

BE PREPARED

Exit point of the sink waste

Aluzyme solution continues to work, the bio film on the internal surface areas of the drainage system enhances the breakdown of solids attached to the internal pipe work area preventing reduced flow, foul odours and blockages occuring.

“I regularly get called out to blocked sink wastes due to fat and grease being poured down the drain when hot. This, I feel, is more an education issue. A campaign to tell people to put fat, oil and grease in a dish to cool before putting in a food-waste bin would be helpful.”

EDUCATION

Full support

Promoting career opportunities through more e ective liaison with schools and improving support for apprentices in the plumbing and heating sector is vital

The plumbing and heating industry is one of continuous learning and adapting to new technology, consumer trends, regulations and legislation. With low-carbon heat sources evolving at a rapid pace, the government is counting on engineers to help the UK reach net zero targets, while ensuring public health.

However, apprenticeship starts are down by 6.1% to 122,290 in the 2022/2023 academic year, compared to 130,240 reported for the same period in the previous

year. With under 19s only accounting for 31.5% of those entering an apprenticeship, more needs to be done to encourage young people to go into the plumbing and heating industry.

The skills shortage issue extends beyond plumbing and heating engineers and includes designers, consultants and lecturers, with the latter particularly in short supply.

Industry support

The COVID-19 outbreak, issues with IR35, insurance

increases and price increases have left many employers questioning the viability of their business so their reticence to take on the commitment of long-term apprentices is understandable.

“Whilst support from employers isn’t as good as it once was, the uptake for the Plumbing and Domestic Heating Technician apprenticeship is encouraging,” says Kevin Wellman, CEO of the CIPHE. “However, engineering apprenticeships aren’t easy, which in turn a ects the dropout rates, and this is where more support is needed.

“In order to upskill the industry, the CIPHE works with colleges and Approved Training Centres to support the delivery of education and

encourage engagement between manufacturers and colleges to ensure that students are up to date with the latest products. It supports young people in the industry through mentoring and career pathway promotion, and works with industry bodies, such as the Worshipful Company of Plumbers (WCP) and the Institute for Apprenticeships and Technical Education (IfATE), to encourage best

practice within apprenticeships and to influence the content of the T-Levels.”

The CIPHE is also involved with Multiply, the governmentfunded programme that helps adults improve their numeracy skills. Aimed at people aged 19 and over who don’t have maths GCSE at grade C (now 4 or 5) or equivalent, this scheme o ers free numeracy courses to build confidence and gain a qualification.

Career pathways

Becoming a qualified plumbing and heating engineer takes years of training and hard work, but …without the right support and guidance, apprentices can find it di cult to study, choose a career pathway and gain employment.

The plumbing and heating industry holds many diverse career pathways. Whether individuals choose to stick with general plumbing, specialise in a certain area or enter into design, research and development or consultancy work – there are plenty of opportunities to diversify.

Although learning will require a significant amount of time spent doing practical work, qualifications play an important part in career progression, so it is important that apprentices take the correct route to becoming a qualified plumbing and heating engineer.

The CIPHE o ers a raft of careers information and advice on its website. The Plumbing & Heating Skills Partnership (PHSP) also o ers advice on the correct routes to becoming a qualified plumbing and heating engineer, which includes how to choose a training provider.

Supporting students

The Worshipful Company of Plumbers (WCP) and the Chartered Institute of Plumbing and Heating Engineering (CIPHE) are developing a joint membership scheme for early-career plumbing and heating professionals. It will be launched later this year and will be promoted at the InstallerSHOW in June.

It is one example of how the industry is increasingly focused on supporting people through the first 10 years of their careers, so that they de… velop the full range of skills and networks to be successful and stay in the industry in the long term. The scheme will support high-performing apprentices from NVQ Level 2 onwards, through their Young Journeyman certification, right up to achieving Master Plumber status.

Engineers and business professionals in WCP and CIPHE have been working with college representatives and early-career talent to develop the programme. The new scheme will o er an attractive membership proposition to early-career talent of both WCP and CIPHE.

“Members will have access to high quality mentoring from a team of expert volunteers to support career development, and to a wide range of

learning events to develop their technical, business, and people skills,” explains Paul Nash OBE (Master WCP). Diversity and inclusion will be extremely important elements, according to Richard Soper, a senior representative for the WCP:

“The scheme will promote equality of opportunity to people entering the scheme and the industry. The programme will also encourage members to o er their experience to charitable programmes linked to water supply and sanitation around the globe.”

The new scheme will include a Young Members’ Forum (YMF), where, according to Martin Shouler (WCP) and Tim Sainty (CIPHE), the joint project leaders, “Ideas will be exchanged and skills enhanced, so that early-career talent can help create the roadmap for the industry’s future, including new sustainable technologies. The YMF will also be a place to showcase skills, catalyse high standards, and develop future leaders for the industry.”

The WCP continues to award bursaries of up to £1,000 for tools and equipment to student plumbers to help them to progress from NVQ Level 2 to 3 MES (plumbing). Colleges and employers are encouraged to support and endorse students who they judge meet the criteria for the annual competitions. The WCP also encourages participation in the SkillPlumb and HIP’s Learner of the Year competitions, to celebrate and recognise talent and to ‘raise the bar’ in the sector.

THE FIX

How to spot a non-compliant pump

Paul

Harmer discusses the need for urgent action to tackle the issue of non-compliant pumps

As of 1 January 2013, it is illegal to sell stand-alone heating circulation pumps that don’t meet the Energy-related Products (ErP) Directive on energy efficiency. However, over the last 12 months, more than 20 brands that don’t meet these minimum efficiency standards have been identified in the UK market.

Reports have suggested that non-compliant pumps can, at times, use nearly five times the power of a compliant pump, which is unacceptable as we transition towards net zero. They can also cost the average homeowner as much as £150 extra a year at a time when they are already faced with growing bills and an increased cost of living.

PAUL

Compliant pumps, or circulators, save customers money

The CIPHE has predominantly focused its efforts on educating the sector on areas such as low temperature heating design, however, issues such as non-compliant pumps directly affect consumers and should be outlawed.

How to identify a non-compliant pump

In order to see whether a pump is compliant installers need to check that there is an EEI (Energy Efficiency Index) on the pump data plate. If it does not have one then the pump is non-compliant.

If it does have an EEI shown on the data plate then a simple rule of thumb procedure can be carried out to check whether it is actually compliant (see Figure 1, right).

The importance of good design

Good pump design is critical for the e cient operation of a low-carbon heating system and whilst fitting a compliant pump is a quick win for energy savings, it is important that installers understand the di erence between fixed and variable speed pumps.

Traditionally central heating circulators have been operating at fi xed speeds and would have been operating this way for the duration of its lifespan, following the initial commissioning stage. However, the introduction of more modern inverter-driven variable-speed pumps have given the pump more control over the system at varying heating loads, leading to greater energy savings. Whilst the fi xed speed pump is set up to operate at peak cold conditions, it continues to run at these high speeds throughout the year at much lower loads. Conversely, the modern variable speed pump will modulate down to meet the varying loads during the heating season.

Proper installation

Whilst selecting an e cient pump control is paramount, there are a number of things to take into consideration before installing a pump:

Rule of thumb for EEI calculation

Multiply maximum power by 0.0035

Example:

• Locate maximum (III) power P(w) on pump data plate (shown on the left)

• Multiply maximum (III) power by 0.0035 and check whether it is below 0.23

• Example: 93 x 0.0035 = EEI of 0.33

• Non compliant due to 0.33>0.23

• Location: The pump should be located on the system to maintain a positive pressure around as much of the heating system as possible. The return connection to the circulator and the expansion vessel should be as close as feasibly possible.

• Neutral connection: When a pump is installed within an open vent system, the cold feed should be connected to a neutral point on the suction side of the circulator and as close as possible.

• Perfect pressure: The circulator must be subjected to a value no lower than the minimum static pressure stated by the manufacturer.

• Middle ground: The circulator should not be installed on the lowest part of a heating system as this allows sediment to collect. It should not be installed on the highest part of the system either, as air getting into it can be a problem.

• Follow instructions: The pump should be installed to manufacturers’ instructions, typically horizontally, so there are no undue loads applied to the bearings. If the pump is installed on a vertical pipe, then you should avoid the pump being installed vertically downwards due to the difficulty of removing trapped air from the circulator impeller casing.

TRAINING EVENT

The CIPHE will be running a techtalk live, alongside Grundfos, during May to discuss both the impact of non-compliant pumps and best practice, design and installation. Visit www.ciphe.org.uk for more details.

Ultimate control

Smart showers save water and can help meet building regulation Part H water calculations, explains Jerry Whiteley

After 10 years of use by four adults, my bathroom was looking tired, so I decided to give it a refresh. Although our shower had served us all very well, with constant daily use, I decided it was time for an upgrade. I set about fitting a new model, and while I was at it, I decided to change the shower door and line the shower cubicle with wet wall panels.

1. Out with the old

To replace the existing shower, I opted for an Aqualisa i System Smart dual outlet, exposed model.

I began the job by decommissioning the old digital shower, sited above the cubicle in the loft. I turned o the power and isolated the water at the spur switch, and isolated the valves on the existing digital unit. Even though this initially looked like a simple installation, I sat and read through the instructions, researching the changes I’d have to make, and found that there were plenty.

The main controller went back into the same location as the old one, as did the isolation valves, so this was a going to be a straightforward swap. You might

wonder why I bothered changing the valves, but I say why wouldn't I? A warranty is only valid if you do exactly as the instructions say, which is why I change everything.

2. Digital connection

The smart valve has cold water and hot water inlets. It’s important to know which type of system you have when ordering the shower, so you order the correct smart valve. I chose one for high pressure, but it could also be used if a combi provided hot water, and two outlets – one for the adjustable ceiling-mounted head, and one for the wall-mounted exposed controller.

This means that the smart valve sends safe and controlled, blended water through to the shower heads via another interconnecting diverter box. The diverter box simply connects directly to the smart valve outlet with a link wire for power. The great thing about the smart valve is that it can be located just about anywhere as it has a 10m range. In my case, I put it directly above the cubicle, but I could have located it in the airing cupboard or under the bath.

3. Mounting the controller

Next, I set about installing the surface-mounted controller: this was my choice – I could have gone for one below-surface. The new controller is fed via the chrome tube that houses the mixed supply (copper pipe inside) to the shower hose and head on the riser rail. I marked out the height and moved it into position. On top is a 15mm push-fit elbow, which allowed me to connect this back to the diverter valve from the pipework.

The overhead shower outlet is a 22mm connection. I scu ed o the chrome pipe where I wanted to connect it, for a watertight seal, and directed a pipe back to the second port on the diverter valve. I sent this pipe back with a backfall from the protruding ceiling-mounted head to ensure that any residual water retained in the leg of pipework after showering didn’t constantly drip after use. Some customers will report a fault with the product if this happens.

Wiring the smart system was just a matter of plugging in the connections, following a simple diagram.

4. Test time

When commissioning, I always put on the water before the power so nothing

runs dry. I removed the shower head from the hose to enable maximum flow for the test run and to clear any debris. I then checked for water tightness and powered up.

This new smart shower can save water, which is useful in the present climate. In fact, when installing a new bathroom or sanitaryware, we must always consider how to save water. Doing this can also help you meet Building Regulation Part H, water calculations.

The smart shower uses wifi and can be controlled by voice activation via the interactive app. The app allows all household members to create their own settings, track water consumption and indicative cost.

InstallerSHOW is returning to the NEC Birmingham on 27-29 June and will be bigger than ever. Now taking place in Hall 5, the event is the best place to see and try new product innovations, meet your peers, make connections with manufacturers and gain industry insights to keep your business ahead of the curve.

To put the scale into context, for those of you who joined us at the NEC last year, the 2023 show will be 66%

larger, and over four times bigger than the 2021 show at the Ricoh Arena.

Visitors will be able to meet over 400 leading manufacturers, test out the latest products, get their technical questions answered and take products away at special show-only prices.

As a CIPHE member, we would love for you to join us. Here are some of the key things that make this an unmissable event:

The present and the future

There’s no doubt that the industry is changing. Heat pumps, hydrogen and the future of heat are all making headlines in national newspapers, and this will be a key theme of InstallerSHOW. Manufacturers will be keen to discuss the latest trials, products, and updates as we continue on the decarbonisation journey.

However, when we look at the heating system as a whole, there are lots of products that we have now that we can implement to have a serious impact on our carbon output, comfort and bills.

Two of our most popular webinars last year were put together in partnership with the CIPHE, on lowtemperature heating training, and sizing the hot water systems of the future (you can watch these on demand on our Crowdcast page www. crowdcast.io/@installer).

The popularity of these sessions shows the appetite for installers to learn more, and that the direction the industry is going, is lowtemperature. It also ties into the CIPHE’s call for installers to continue their professional development, and for all engineers to hold level three qualifications.

Although a lot of importance is put on the number of boiler installs, and

heat pump targets, the heat source isn’t the end of the debate. As an industry, we need to consider the optimal design of the system, including products like cylinders, TRVs, heat loss calculations, radiator sizes, pump sizes, water treatment, controls, the list goes on and on.

Plus with more smart technology bringing our products together, discussions around solar, battery storage, thermal batteries, EV chargers and connected products are quickly becoming part of the conversation.

It will be the installers who design, fit and commission these systems. They’re the experts in the field who deal

with customers every day. There’s plenty of opportunity in the industry, but we know that heating, plumbing and electrical engineers will be the key to improving and decarbonising our homes.

Getting hands on with these products, getting your questions answered by the experts, and benefiting from show-only offers, are some of the key reasons why a trip to InstallerSHOW is well worth it.

Training and debate

In 2023, InstallerSHOW will be hosting more unrivalled live content than ever before. This includes a full schedule of live debates and seminars in the elemental content theatres, industry

standards and expertise in the Installer Training Theatre and our brand-new interactive demo area Installing the Future. NOW! – where visitors get the chance to see and try the new products being used to help meet tomorrow’s net zero challenges.

Plus the Bathroom Manufacturers Association will be providing three days of bespoke content in a new feature for 2023 for plumbing and bathroom installers, and Solar Energy UK and MCS have partnered with InstallerSHOW for a feature dedicated to green energy and the electrification of heat.

Especially for CIPHE members, the Institute will be hosting a daily training session on the InstallerTRAINING Theatre, plus hosting a VIP breakfast morning on the InstallerPLAZA.

All this content is free to access over the three days with new and exciting sessions every day.

Have a laugh with your industry colleagues

One of the reasons why InstallerSHOW has become so popular for engineers is that it’s a chance to bring the industry together, and have fun.

There is a lot of responsibility for engineers who run, or work in trade businesses, and it can be easy to get into your own bubble.

InstallerSHOW is a great place to meet other engineers and CIPHE members, who have similar experiences to yourself. You can share ideas, discuss your experiences, and enjoy the hospitality provided by InstallerSHOW and its exhibitors.

There are also plenty of things to do on stands, from challenges, to prize draws and giveaways, plus there will be some famous faces in attendance over the three days.

We’re looking forward to meeting up with the CIPHE and its members, and we hope to see you there.

InstallerSHOW takes place at the NEC Birmingham on 27-29 June 2023. Parking at the venue is free for InstallerSHOW visitors. To register for your free entry passes, please head to www.installershow.com.

USA Code of Practice

Dave Viola discusses the importance of global collaboration in plumbing to ensure public health

Plumbing construction and plumber licensing is not regulated at a national level in the USA. Each state determines its requirements for plumbers and plumbing codes and has regulations administered on a state-wide level. However, a few states are without state-wide regulations and rely on local government entities to establish and

regulate plumbing practices.

“The US Constitution places the responsibility of regulating construction with each state,” explains Dave Viola, CEO of the International Association of Plumbing and Mechanical Officials (IAPMO). “As a result, plumbing is addressed differently in each state. Almost every locality and state in the US adopts a

model plumbing code, such as the Uniform Plumbing Code, developed by IAPMO that brings together a cross section of expert volunteers that include plumbers, contractors, inspectors, engineers, manufacturers, research and testing labs, and other industry experts. The result is a document that is designed to be adopted by states and local authorities as an enforceable regulation that establishes safe provisions for water and sanitation, while reflecting the latest technologies, and addressing safety and sustainability. As so many states and localities adopt model codes, there is significant uniformity in plumbing code requirements.

Young blood

According to Viola, the USA does not have enough young people moving into the plumbing industry and other skilled trades. Much like the UK, he says this lack of apprentices is one of the biggest challenges facing the American economy in the future.

“The World Plumbing Council, IAPMO and many industry partners have made concerted efforts to reshape what I refer to as priorities in education and occupational bias,” says Viola. “Reshaping educational priorities means changing the education system in the USA from pushing students and students’ parents towards college and university learning and away from skilled trades.

“This is a big job as the problem has existed since the late seventies and early eighties (when I was still in school and considering a career path). Unacceptable and erroneous occupational biases that we are working to change is that plumbing pays less than those with a college education and that the industry is for men and those lacking intelligence.”

Staying the course

Plumbing apprenticeships in America are typically four to five years, which is established by the programme and local licensing requirements. These apprentice training programmes are managed at the local level by organisations such as the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry, the National Association of Plumbing Heating and Cooling Contractors, or other locally-operated schools. Apprentice education includes hands-on training under the supervision of an experienced

journeyman plumber and attending classes of related technical instruction.

“With anything requiring hard work and commitment, there will always be attrition,” admits Viola. “I know our partners that operate apprentice programmes are always looking to understand why candidates drop out and continually strive to ensure the training programmes are appropriate and the instructors are properly trained to ensure apprentices are getting what they need to succeed.”

Global health

Through his involvement with the WPC, Viola works with the World Health Organisation and the United Nations. The World Plumbing Council has Non-Governmental Organization (NGO) Status with the World Health Organization (WHO). This designation establishes official relations with the WPC, acknowledging the importance of plumbing and public health, and a direct voice into the team focused on water and sanitation-related diseases. The WHO and WPC have collaborated on important guidance documents such as the Health Aspects of Plumbing, WASH FIT, and others focused on water distribution and sanitation systems.

The WPC, IWSH and IAPMO are founding partners of the pledge to address the serious issue of lead in drinking water – a global pledge that aims to build momentum to reduce lead exposure from drinking water and the products that convey it.

“The problem is significant, especially for children and those living in disadvantaged communities around the world,” explains Viola. “The good news is getting the lead out of drinking water systems is wholly achievable. The founding partners invite any entity interested in supporting the initiative to join by visiting globalleadfreewater.org.”

Industry support

“For as long as I’ve been involved with the WPC, we’ve had the benefit of Kevin Wellman and CIPHE’s leadership, support and broad perspective of plumbing industry needs and challenges,” says Dave. “CIPHE’s involvement has meant the WPC has a better understanding of members’ needs around the world, successfully strategised for future growth, made events worthwhile, and remained relevant.”

Hot topic

safe

Although the UK is renowned for its inclement weather, summer temperatures are now reaching highs of 40°C. Hotter summers may be welcomed by many people, keen to make the most of the sunshine, but for plumbing and heating installers the warmer weather can put them at serious risk of heat-related illnesses.

Heat stress

Working in confined spaces with heat emitting equipment and well-insulated loft spaces is part and parcel of plumbing and heating installers’ jobs. However, once the outside temperature rises, heat stress becomes a risk to human health.

According to the Health and Safety Executive (HSE), heat stress occurs when the body is no longer able to control its internal temperature. Factors such as work rate, humidity and workwear can lead to heat stress, particularly when temperatures are high outside.

Symptoms of heat stress include:

✓ Inability to concentrate

✓ Muscle cramps

✓ Heat rash

✓ Severe thirst

✓ Fainting

✓ Heat exhaustion – fatigue, nausea, headache, moist skin

✓ Heat stroke – hot dry skin, confusion, convulsions, loss of consciousness. This is the most severe and can result in death.

Mitigate the risk

The most obvious solution to avoiding heat stress is to cool down by wearing

lightweight clothing, reducing work rates and drinking plenty of cool water. However, in some situations this may not be su cient or even possible. It’s therefore important that risk assessments are carried out before you start a job.

Limiting your work rate and length of exposure can reduce the risk of heat stroke. When carrying out jobs on hot days, it can help to work in shorter bursts at cooler times of the day, such as earlier in the morning.

Working in hot conditions causes sweating, which means losing vital water that must be replaced. Therefore, regular breaks in cooler areas and frequent hydration are essential to prevent dehydration.

drivers admitted they never apply sun cream in the UK, despite more than two fifths (44%) sharing their concern about developing skin cancer.

Although windows in vehicles are fairly e ective at blocking out UVB rays, thought to be the most carcinogenic, they aren’t as e ective at blocking UVA rays, which aren’t as harmful, but are still implicated in skin cancers and general sun damage to the skin.

Driving safely

Driving also has its risks, particularly for those who drive vehicles without adequately protecting themselves from the sun. In fact, Melanoma UK research found that drivers do not realise that they are could be overexposed to harmful UVA and UVB rays when driving their vehicles during daylight hours.

Another survey by Confused.com found that more than one in four (28%) UK motorists have been burnt through a van or car window. One in six (17%)

“Professionals need to protect their skin when they are driving,” says Gillian Nuttall, founder of Melanoma UK. “Dermatologists will attest to the di erence in the damage seen in the skin of a driver (a lot of right-sided skin damage – the so called ‘van tan’). We know that there are thousands of undiagnosed skin cancer cases that are coming down the track after lockdown – with patients being unable to be seen by GPs and lack of dermatology appointments.

“Windows of vehicles o er very little protection against the sun. Harmful rays can penetrate the glass. It’s noteworthy that UVA rays are less associated with skin cancer than UVB rays (they are fi ltered by car windows), but they can lead to DNA damage that may result in skin cancer. We would recommend the use of sunscreen at all times when outdoors – even inside your vehicle.”

As UK summers become increasingly hot, it’s vital that installers know how to keep themselves
