Consumer demand

Driven by the need to reduce the UK’s carbon emissions the shift to low carbon heating has been underway for a number of years. On a domestic level, Air Source Heat Pumps have emerged as perhaps the key technology to shift home heating towards electricity and away from gas.

The challenge is a considerable one. Gas has been the main fuel of choice for decades in domestic heating. Installers are familiar with how products work, and how to install, commission and repair them. Understandably, many will be content to continue working with gas appliances for the foreseeable future. Equally, consumers are broadly comfortable with their operation and familiar with the type of heat being delivered.

One key issue to greater heat pump adoption is consumer demand. In a recent survey of consumers by Energy Systems Catapult 69% said they don’t know enough about heat pump technology.

However, it would appear the people best placed to provide more information about Heat Pump technology – heating engineers – are also yet to be convinced. A recent survey, conducted by Baxi and Gemserve in August 2024, reveals that just 9% of installers are currently ﬁtting heat pumps.

And it would appear that this position will only change slowly. The survey also revealed that half of installers say they are “somewhat” or “extremely unlikely” to start ﬁtting heat pumps in the next three years. When it comes to Heat Pumps, it is clear that if the technology is to more widely adopted then Heating Engineers require more information.

One route to achieve this is practical training. A number of manufacturers and others are increasing the amount of Heat Pump training available. We recently visited Baxi’s new training centre in Warwick where the company runs a number of hands-on training courses for installers interested in learning more about Heat Pumps. The company also has other facilities across the country to bring training closer to installers.

Once armed with greater levels of knowledge it is likely engineers will feel more conﬁdent in discussing Heat Pumps with potential customers and installing the technology.

However, it is homeowners that will make the ﬁnal decision on the type of heating system being installed at their property. If more heat pumps are to be installed the consumer barriers around them need to be addressed and stronger demand fostered.

LOW CONSUMER HEAT PUMP AWARENESS

In a survey of UK consumers, 69% said they don’t know enough about heat pump technology.

The survey of more than 1,000 mortgage homeowners, outright homeowners and aspiring homeowners also revealed less than a third (31%) said they are familiar with heat pumps (know a fair amount or a lot about them). 18% of respondents said they don’t trust the technology. The research, by Energy Systems Catapult in partnership with Heatio and Perenna, indicated that a lack of affordability, ﬁnance options and lack of knowledge and trust in heat pump and solar panel technology, the installation process and proposed beneﬁts are the main barriers to installation.

Rebecca Sweeney, Business Leader, Homes at Energy Systems Catapult said: “To transform the UK energy system and meet our Net Zero carbon reduction targets, it is essential we engage consumers by offering them innovative energy products and services that they want to take up.”

NUMBER OF HEATING ENGINEERS FITTING

HEAT PUMPS REMAINS LOW

Baxi has published its 2024 Installer Skills Survey, revealing that attitudes of heating engineers towards low carbon heating are hard to shift.

Over 300 installers took part in the survey, conducted in August 2024 in partnership with green supply chain consultancy Gemserv. It reveals that just 9% of installers are ﬁtting heat pumps. This is up from 3% in 2022 and 7% in 2023.

Sentiment towards heat pump installation in the future looks weak, with half of installers saying they are “somewhat” or “extremely unlikely” to start ﬁtting heat pumps in the next three years. This compares to 46% in 2022 and even less conﬁdence, 53%, in 2023. There is more enthusiasm for hybrid systems – where a heat pump is combined with a gas boiler – with 30% of installers showing interest.

Government schemes, such as the Boiler Upgrade Scheme (BUS), are met with frustration in the survey. Only 9% of installers rate government schemes as ‘’good’’ or ‘’excellent’’ and 42% say customers never mention the BUS.

A lack of confidence to promote and install low-carbon heating technologies has been a feature of the Installer Skills Survey since it began in 2022. This year, there is a slight improvement, with 11% of installers saying they are ‘extremely confident’ in discussing low-carbon technologies (up from 7% in 2023) and 35% ‘moderately confident’. This appears to indicate that while training opportunities and industry communication are having a positive effect, many installers still lack the expertise to fully promote and install low-carbon heating technologies.

Ian Trott, Baxi’s Head of UK Training said, “While the 2024 survey shows some positive developments, particularly regarding hybrid systems, many of the challenges highlighted by previous surveys, such as insufficient training, poor government support, low consumer demand, haven’t moved on. The transition to low-carbon heating will require more targeted interventions to support installers in overcoming these barriers.”

IDEAL HEATING CELEBRATES

LOGIC’S FIVE MILLION MILESTONE

WILO LAUNCHES NEW SERVICE TO TACKLE NON-COMPLIANTPUMPS

To prevent non-compliant heating circulation pumps from being installed unwittingly, Wilo has launched a new service to help installers check the pumps they are fitting are safe for use and compliant with the Energy-related Products (ErP) regulation.

Since 1 January 2022, heating circulation pumps, also known as heating circulators, sold in the UK market must meet the ErP regulations. To meet these regulations, they must have an energy efficiency index (EEI) of ≤ 0.23, as well as conform to other design standards.

To help installers understand if the pumps are compliant before they fit them, installers can take a picture of the label and send supporting documentation of the pump to Wilo, whose team will then perform a visual check of the information to confirm if the pump labelling meets the requirements within one working day. Andy Thompson, National Sales Manager – Plumbing and Heating at Wilo UK, said: “By simply sending us a picture of the label and relevant supporting documentation, we’ll be able to check if the pump labelling conforms to the ErP legislation, what the EEI of the pump is, and if the pump runs on outdated technology, which again is a mark of non-compliance.”

Business Matters

PART 8: DO YOU NEED A WEBSITE?

Katie Hall, Marketing Manager for Fergus, looks at the case for and against investing in a website for your company.

In today's digital era, having an online presence seems almost obligatory for trade businesses. However, is it essential for every tradesperson to have a website?

A website serves as a digital storefront that’s open 24/7, giving potential clients the ability to discover your services anytime, anywhere. For many, this extended reach is invaluable, especially when combined with the credibility that a well-maintained site can bring. Displaying completed projects and testimonials offers a strong ﬁrst impression, showcasing the quality and scope of your work. Online booking systems and contact forms enhance customer convenience.

However, the journey to creating and maintaining a website is not without its challenges. The initial costs, ongoing maintenance, and the time commitment required to keep it updated can be significant –especially for busy tradies.

For those who decide to take the plunge, ensuring that your website is user-friendly is paramount. A clear, straightforward design with easy-to-find contact details, a portfolio of your work, and client testimonials can make a world of difference. It’s also worth considering the addition of SEO (Search Engine Optimisation) tools to improve your site’s visibility on search engines, driving more traffic your way.

Alternatives to building a website

Not ready to commit to a full-fledged website? Social media platforms like Facebook and Instagram can serve as effective alternatives. These platforms allow you to showcase your work, interact with clients, and gather reviews without the need for a website. Setting up a Google My Business listing can significantly boost your local visibility, making it easier for potential clients to find you in local searches. And, of course, the power of word-of-mouth and strong client relationships cannot be underestimated —referrals remain one of the most effective ways to generate new business.

Whatever path you choose, the key is to stay visible, credible, and connected with your clients.

To ensure ASHPs run as efficiently as possible, they need to be correctly installed and commissioned.

Here, Paul Bailey, Heat Pump Engineer at Baxi, shares a commissioner’s insights that can benefit ASHP installers.

Commissioning -AVITALTOOL

Heat pumps are generally very reliable so, when issues do arise, they tend to be as a result of a wider system issue, incorrect installation or the wrong settings being used. Like any heating source, ASHPs work at their most efficient when installed correctly in line with the manufacturer’s instructions. This is why accurate commissioning is essential.

The process ensures settings can be optimised to meet customer heating requirements and makes sure the technology is operating at peak capacity. Since the operating principles of heat pumps are still in their infancy and new to many installers, assisted commissioning is a great way to reassure both yourself and your customers that the installed solution will do the best job it can.

Baxi offers assisted commissioning on the ﬁrst installation to help identify errors and make any necessary corrections. All factory speciﬁcations are checked to ensure the system can operate reliably over an extended period and can therefore provide efficiency and energy savings to homeowners. Correct commissioning which includes proper inspection of setup and operation, is a critical step installers should take to mitigate the risk of any potential underperformance when approaching an ASHP installation.

Inspection of setup and operation

Commissioning exists to make sure all factory speciﬁcations are adhered to. This includes checking the setup and operation of a system. As part of the initial checks, things like condensate drainage, a solid base and minimum clearances around the appliance should all be checked.

So what exactly should those checks be looking out for? It’s important to note that ASHPs should be positioned close to the property, using minimal pipework and kept within easy access for servicing and

maintenance. Sufficient space is also required for the systems to expel cold air out and they should be placed on a solid surface to the manufacturer’s speciﬁcation. It is at this point that checks can also be made to ensure the heat pump performs to the speciﬁcation prescribed by room-by-room heat loss calculations. As long as the system including its radiators and emitters have been accurately sized, the home should feel suitably comfortable, even if those radiators are emitting lower temperatures.

Getting these calculations right allows ASHPs to maximise energy efficiency and lower utility bills. Accurate sizing and installation also means installers can schedule domestic hot water times and temperatures that work for customers.

To make heat loss calculations easier, once an installer completes Baxi’s training course they will receive a three-month subscription to Carno with unlimited projects, free of charge. Carno helps installers to pre-qualify their prospective customers quickly with indicative pricing, using available data and images of the customer’s property without the need for a pre-visit.

Users can complete a full room-by-room heat loss calculation and the app will provide a ﬁnalised schedule of equipment including ASHPs, water cylinders and heat emitters from Baxi’s catalogue.

Support and training

To put any installer concerns at ease and make sure systems are working correctly for everyone, Baxi’s heat pump engineers can guide them through the commissioning process from start to ﬁnish. This ensures any issues are identiﬁed and dealt with early on so the system can carry on operating efficiently.

For those installers who wish to become more familiar with the installation process and qualiﬁed to install the systems, they can also beneﬁt from Baxi’s full suite of ASHP training courses. From understanding how air source heat pumps work to designing, installing and commissioning them, the programmes assist installers at every level of experience to work comfortably and efficiently with the technology.

Additionally, to support those who qualify as a Baxi Heat Pump Installer with an extra incentive, installers can receive £600 cashback on their ﬁrst three eligible installations of Baxi HP-40 ASHPs before 6 January 2025. To claim the cashback, heat pumps must be registered through Baxi works and an assisted commissioning with a Baxi Engineer must be completed on the ﬁrst installation if an installer has not already done so previously.

Off-grid application

Many homes are already adopting ASHP technology and there are plenty of success stories where accurate commissioning has played a crucial role in maximising efficiency. When Jonathan and Emma Hayes built their 2,600 sq ft property in Suffolk, they required a heating system capable of improving energy efficiency while also being suitable for the off-grid application.

The new property was well insulated and as energy efficient as possible – the perfect conditions for a heat pump. After carrying out detailed heat loss calculations on the property, the engineer recommended the Baxi HP40 11kW ASHP with a 250-litre hot water cylinder. This solution feeds the underﬂoor heating, which can emit 11kW of heat even on the coldest of days.

Renew East who recommended Baxi’s HP40 Monobloc Air Source Heat Pump (ASHP) were able to access Baxi’s full heat pump services and expertise both before and during the project in the run-up to its installation.

Once the installation was complete, they were also able to beneﬁt from commissioning supervision offered by Baxi’s expert heat pump engineers, who could ensure the solution was able to deliver its intended design performance prior to handover to the homeowners.

Renew East Director Luke Nicholls said: “The top-notch extra support Baxi has given has also helped the project to run like clockwork. Often with other manufacturers there’s no return of an email, but every single one of my questions has been answered within just a few hours.

“The supervised commissioning support was something I had never experienced before with any other manufacturer, so I didn’t know what to expect, but having the engineer physically with me on site was really helpful. They know the product inside out, so it just made the whole process straightforward.”

LOW CARBON HEATING

HEAT PUMP UPGRADE

Innovations in heat pump technology and refrigerants are improving the environmental beneﬁts of systems. For installers ready to adapt, embracing these developments is a chance to capitalise on a growing market while positioning themselves as experts in eco-friendly, sustainable heating solutions.

One of the most notable recent advancements in the heat pump market is the introduction of R290 refrigerant in air source heat pumps. This new refrigerant is transforming the way we think about environmentally friendly heating and promises to make heat pumps even more sustainable.

Advancements in heat pump technology are making systems greener and more energy efficient than ever, says Stuart McWhinnie, Assistant Product Manager at Grant UK.

As with any innovation, however, R290 raises important questions for installers.

‘R290’, also known commercially as propane, is a by-product of the natural gas process that also acts as an excellent heat transfer medium when used in the vapour compression cycle of a heat pump. R290 has been successfully used for several years in air conditioning and refrigeration systems. Its adoption in the UK heat pump market is gaining momentum due to its extremely low Global Warming Potential (GWP) of just 3.

Installers might wonder how it differs from other refrigerants in terms of installation and safety. One key difference is that R290 requires additional safety precautions during installation and servicing. However, R290 operates in a similar manner to other refrigerants within heat pumps. Like R32 and R410a refrigerants, it cycles between liquid and gaseous phases to transfer latent heat from the outside air into useful heat energy for the property’s heating circuit. But thanks to its superior thermodynamic properties, R290 can capture and release heat more effectively, making the systems that use it more energy efficient. This increased efficiency can translate into potential energy beneﬁts for homeowners and a more sustainable heating option overall, compared to units using more commonly available refrigerants.

As R290 rises in popularity, another concern is whether it will be readily available for installers in the UK. Currently, R290 is widely used in air conditioning and refrigeration, so it already has an established supply chain. Its use in heat pumps is growing and availability is expected to increase as demand rises. Suppliers are expanding their stock to meet this growing demand, so installers should not face signiﬁcant issues in sourcing R290 for installations.

Fifth generation

Grant UK launched its latest product line, the Aerona 290 heat pump range, in October 2024. This range marks the fifth generation of our air source heat pumps and takes full advantage of the energy efficiency and low environmental impact of R290 refrigerant without sacrificing performance. These units have earned A+++ energy efficiency ratings (at 35°C flow temperature) and have been tested to perform in extreme temperatures ranging from -25°C to 35°C, making them suitable for homes in a variety of climates.

The Aerona 290 units have ultra-low noise levels, achieving Quiet Mark accreditation thanks to sound-reducing technologies, including acoustic insulation and anti-vibration feet, making them a practical choice for both urban and rural homes, where noise reduction is a priority. Research has highlighted concerns about the appearance of heat pumps, and Grant UK has responded. The Aerona 290 has a sleek black design for a modern aesthetic. Designed to suit a range of property types, from new builds to retroﬁt projects, they provide a versatile solution for various installations.

Training

To ensure installers are fully prepared to work with R290 refrigerant and the new Aerona 290 units, Grant UK is offering comprehensive training at its Training Academy. The course is designed to equip installers with the skills and knowledge needed to safely and effectively install, commission and service R290-based heat pumps.

The Aerona 290 Air Source Heat Pump installer course covers everything from system installation and electrical wiring to conﬁguring the Aerona Smart heat pump controller and fault ﬁnding. Special attention is given to safe handling practices, protective zones and precautions when dealing with R290 refrigerant.

System design

For installers new to heat pump systems or looking to reﬁne their expertise, Grant is also offering a one-day system design course. This course focuses on the basics of heat pump system design, including heat loss calculations, heat pump selection, emitter sizing and sound level calculations. This course is especially valuable for those looking to ensure that each system is correctly sized for optimal performance and customer satisfaction.

Alongside the new Aerona 290 heat pumps, Grant UK is launching a range of ancillary products that will give installers greater flexibility when designing systems. These include new QR Smart Pre-Plumbed cylinders and additional smart heat pump controller kits, which are compatible with both the Aerona 290 and Aerona³ heat pump ranges. These products have been designed to offer installers more flexibility and ease when working with various system configurations, ensuring that the heat pump system is optimised for each installation.

HELP HOMEOWNERS MAKE low- carbon choices

Reducing a home’s impact has to start by selecting an efficient heating and hot water system. These systems ensure comfort and convenience and combined with the right levels of insulation, signiﬁcantly inﬂuence a home's carbon footprint. It’s important to recognise that traditional systems can be energy-intensive, especially those involving separate heating and hot water appliances. Installers can help homeowners achieve energy savings and reduce emissions by advising on high-efficiency systems that combine both functions.

Taking control of your controls

Once the right system is in place, managing energy usage daily becomes equally as important. Intelligent control systems make such a difference in enabling homeowners to optimise their heating for maximum comfort. Installers can introduce customers to smart control technologies that adapt to their heating habits, ensuring the boiler only runs when necessary and at the most efficient capacity.

Likewise, smart thermostats and AI-powered management systems can analyse usage patterns, adjust to external factors such as the weather and continuously tweak the system's output. By reducing unnecessary energy consumption, homeowners can lower their carbon emissions. This level of intelligent control gives the homeowner more conﬁdence that their system is running at peak efficiency, contributing to a more energy-efficient home.

Informed decisions

In addition to smart controls, another key tool in the installer's arsenal is Home Energy Management Systems (HEMS), providing detailed reports on a home's energy usage, allowing homeowners to make data-driven decisions. When homeowners can see exactly how much energy they're using – and when – they can take active steps to reduce consumption. By using the data, installers can demonstrate the value of this insight by showing how even small behavioural

With growing pressure to adopt low-carbon heating solutions, homeowners are increasingly seeking advice from installers to help them make informed, sustainable choices. Sean Keleher, Technical Director at Navien UK, discusses how installers can support homeowners in reducing their carbon footprint by making low-carbon choices, and looks at the systems and controls they can recommend.

smart thermostats and AI-powered management systems can analyse usage patterns, adjust to external factors such as the weather and continuously tweak the system's output.

changes can lead to measurable reductions in energy use and, by extension, lower carbon emissions (as well as bills). By offering systems that include HEMS functionality, installers enable homeowners to improve efficiency and gain a deeper understanding of their energy habits, reinforcing their commitment to low-carbon living.

Streamline energy use

The Navien NCB500 ON and NCB700 ON Combi Crossover boilers, when combined with the Navien Smart Plus ON AI Controller, provide an excellent solution for homeowners who want to reduce their carbon footprint and manage their energy-usage.

OFF-GRID DECARBONISATION

Malcolm Farrow, Head of Public Affairs at OFTEC argues that achieving net zero and tackling social inequality can go hand in hand.

Summer 2024 saw huge change in Westminster.

We have a new party in government, a new prime minister, a new secretary of state for energy and hundreds of new MPs. However, in rural communities up and down the country, homes and businesses still face the same decarbonisation challenges and the same barriers to transitioning to low carbon heating. Labour now has unique opportunity to forge a new path which delivers on net zero whilst tackling social inequality.

Currently, plans for off-grid decarbonisation are somewhat in a state of limbo. The previous Conservative government proposed to phase out the installation of fossil fuel boilers and transition these properties onto heat pumps. However, after pressure from consumers and backbench MPs, plans were repeatedly put on hold and no ﬁrm policies were put in place.

This was driven by several factors. Firstly, the nature of rural off-grid housing stock makes it very difficult to switch these buildings to a heat pump. Properties typically have poor energy efficiency and require signiﬁcant renovation as part of a heat pump installation. Even with the available government grants, the cost and disruption were a real barrier.

Weak demand

The cost-of-living crisis squeezed household ﬁnances - and government budgets - even further which meant that there hasn’t been the money to enable households to make these big investments. Weak consumer demand has also affected industry conﬁdence and meant there weren’t enough installers to deliver on the government’s targets even if they could be met.

The existing Boiler Upgrade Scheme provides up to £7,500 for a heat pump installation, increasing deployment but disproportionally beneﬁting higher income households as they have the disposable income to meet the remaining cost. Some argue that as long as heat pumps are installed, that’s all that matters. However, low-income households, who typically live in poorer quality housing, are unlikely to apply, and such policies risk a growing social divide on the journey to net zero. But could that emphasis change? Social justice is hard-wired into Labour’s DNA and could inform their approach to decarbonisation. With the right blend of policies, achieving net zero, tackling the economic inequality blighting so many rural communities and creating opportunities by ﬁxing the skills shortage

could go hand in hand. This would require policies rooted in a more holistic approach and driven by an overarching commitment to fairness, rather than one just focussing on heat pump installations.

Skills shortage

The skills shortage is an underlying challenge that has held back the rollout of heat pumps in the heating sector. It affects not just heat pump installers but all areas of the retroﬁt supply chain. Labour needs to deliver a skills revolution, starting from schools all the way through to college and apprenticeships. Our education system needs to give equal value to the skilled technical trades and promote the opportunities of a career in the industry. Alongside having the workforce, increasing the pace of low carbon deployment is critical too, and can be achieved by focussing on policies to prioritise heat pumps initially where economies of scale are easiest to achieve. This means targeting urban and suburban

areas which will help to bring down costs and ultimately make them more accessible for harder to treat off-grid homes.

This is key because heat pumps have a key role to play in the decarbonisation of the whole domestic heating sector. OFTEC is actively supporting the rollout through our heat pump training courses to help more installers diversify. In fact, over a third of all OFTEC training undertaken so far this year was heat pump training.

However, for some properties, heat pumps still won’t be viable. That’s not because their owners aren’t concerned about carbon emissions. Far from it, these households are often some of the most vocal and determined to be greener. For many rural off gas grid homes the existing challenges outlined above will not be easily overcome, even with more socially targeted retroﬁt funding. What’s overlooked here is the need for consumer choice and availability of the type of low carbon heating system which meets these individual’s needs.

Our education system needs to give equal value to the skilled technical trades and promote the opportunities of a career in the industry.

Such pragmatism is important, given the political tightrope the new government has to walk. Whilst Labour is fully committed to net zero, the Party will be aware of the backlash the last government faced trying to force homes to change their heating system. As a result, during the election, Labour said this is not a route they would go down. Recent changes to the Winter Fuel Payment has also created difficulties for the government and will have a big impact on older people who live in rural areas. Labour will be cautious about the policies they push forward to this voter group.

Renewable liquid fuels

It’s increasingly clear that other alternatives will be needed. We’ve demonstrated the viability of renewable liquid fuels such as Hydrotreated Vegetable Oil (HVO) as a replacement to kerosene. With minimal disruption, a simple conversion to the boiler of less than £500 and a potential to reduce emissions by 88%, it’s an ideal solution to the problems we’ve outlined. Our survey of several thousand rural households also shows over 80% support.

We will continue to work proactively and positively with the new government to secure the policy support needed to rollout renewable liquid fuels more widely. The industry already has an extensive workforce, supply chain, training, experience and high safety standards so it is well placed to scale up the transition to renewable liquid fuels very quickly. All we need, is the green light from government.

Trends in BATHROOM PLUMBING

The bathroom industry has undergone significant evolution in recent years, driven by technological advancements, changing consumer preferences, and an increasing emphasis on sustainability. Andrew Shankster, Product Training Manager at Geberit UK explores key trends shaping the future of bathroom design and installation, and how industry professionals can leverage them to their advantage.

One of the most notable shifts in the industry is the move towards multi-layer piping systems. These solutions offer an alternative to traditional materials, addressing common issues such as corrosion, scaling, and heat loss. Multi-layer pipes typically consist of three layers, with a central aluminium layer sandwiched between two plastic layers. This construction offers a combination of flexibility and stability, making installation more efficient.

The beneﬁts of multi-layer piping systems for installers are substantial. The installation process is streamlined, with no need for hot works or additional consumables on site. These systems are versatile, suitable for various applications from potable water to heating systems. Their durability, including resistance to

corrosion, cracking, and scale build-up, ensures a longer service life. Furthermore, the excellent thermal insulation properties of multi-layer pipes contribute to energy efficiency, aligning with the requirements of Part L of the Building Regulations for the conservation of fuel and power.

Products such as Geberit FlowFit exemplify these advantages, offering press-ﬁt technology that further optimises the installation process. With only two pressing jaws required for the entire range, it presents an efficient solution that can enhance productivity, particularly in conﬁned spaces. Embracing multi-layer piping systems can differentiate installers in a competitive market, offering clients a modern, efficient solution that aligns with the growing demand for sustainable and cost-effective installations.

The rise of shower toilets

Another trend gaining signiﬁcant traction is the increasing popularity of shower toilets. These advanced ﬁxtures, which combine the functions of a toilet and a bidet, are increasingly perceived as a luxury item in residential bathrooms and are becoming more prevalent in commercial settings.

Shower toilets, such as the Geberit AquaClean Alba, offer several beneﬁts that resonate with modern consumers: enhanced hygiene through integrated washing functions, improved comfort features like heated seats and adjustable water temperature, increased accessibility for users with mobility issues, and sustainability beneﬁts through reduced toilet paper usage and efficient water consumption.

For installers, the growing demand for shower toilets presents an opportunity to expand their service offerings and develop expertise in high-value installations. While the installation process may require additional skills, particularly regarding electrical connections and specialised water supply requirements, mastering these systems can position installers as specialists in a growing market segment.

Concealed systems

The trend towards minimalist, spa-like bathrooms has driven demand for concealed installation systems. These behind-the-wall solutions create a sleek, uncluttered aesthetic while maximising space – a crucial consideration in modern bathroom design. Concealed cisterns for wall-hung toilets are at the forefront of this trend. While they may present initial challenges, such as accommodating uneven wall surfaces or working in compact spaces, the end result is a stylish and space-efficient solution that increasingly appeals to clients.

To successfully navigate concealed system installations, installers should familiarise themselves with adjustable mounting frames to compensate for wall irregularities, utilise manufacturer-provided templates and measuring guides for precise positioning, and consider systems designed for efficient installation, such as Geberit Sigma and Omega concealed cisterns. These products offer features like tool-free installation options and easily accessible service openings, facilitating both installation and future maintenance.

Personalised bathroom designs

Perhaps one of the most signiﬁcant shifts in the industry is the growing demand for personalised, bespoke bathroom designs. Clients increasingly view their bathrooms as personal retreats and seek spaces that reﬂect individual styles and needs. This trend towards customisation is evident in the popularity of modular bathroom furniture and mix-and-match concepts. For example, Geberit's Mix & Match concept allows customers to combine basins and furniture across different ranges, creating personalised wash places.

For installers, this trend towards bespoke designs necessitates an expanded

product knowledge base, increased ﬂexibility in working with diverse materials and installation requirements, and enhanced collaboration with designers and clients to understand and implement unique visions. It also requires problem-solving skills to overcome installation challenges that may arise from custom designs.

The importance of training

To maximise opportunities in this evolving market, installers should prioritise continuous professional development. This includes staying updated on the latest products and installation techniques through manufacturer training programmes and industry events. Investing in specialised tools for working with new materials and systems, such as press-ﬁt tools for multi-layer piping, can enhance efficiency and capability.

Marketing strategies should be adapted to showcase expertise in trending installations, such as shower toilets or concealed systems, through digital platforms and client testimonials. Building strong relationships with suppliers who offer products aligned with these trends

can provide a competitive edge and potential business referrals.

Additionally, the ability to educate clients on the beneﬁts of new technologies and designs can be a valuable differentiator. Installers who can effectively communicate the advantages of bathroom solutions –whether it's the improved hygiene of a shower toilet or the space-saving beneﬁts of a concealed cistern – are better positioned to secure high-value projects.

The bathroom industry is undergoing a signiﬁcant transformation, and installers have the opportunity to be at the forefront of this evolution. By embracing these trends and continually expanding their skills and knowledge, plumbing and heating professionals can offer clients bathrooms that are not only functional but also sustainable, personalised, and innovative. Adapting to these changes and positioning oneself as an expert in modern bathroom solutions can lead to business growth and success in this dynamic market.

INSIDE A PRV

Ed Morris, Technical Manager at Altecnic, delves into the inner workings of two pressure reducing valves: the Caleffi Series 533 PRV and the Caleffi Series 535 High Temperature PRV.

Apressure reducing valve (PRV) is an essential device in plumbing applications, designed to regulate and maintain a constant downstream pressure, regardless of ﬂuctuations in the incoming pressure. By controlling the pressure, PRVs protect appliances and systems from damage, conserve energy, and optimise performance.

The Caleffi Series 533 Pressure Reducing Valve

The Caleffi Series 533 is a widely used PRV in residential and light commercial applications. The core components of this valve include:

Adjusting screw

The adjusting screw is located at the top of the valve and plays a critical role in setting the desired downstream pressure. By tightening or loosening the screw, the tension on the internal spring changes, which alters the force applied to the diaphragm. This controls the outlet pressure. The adjusting screw allows for the valve’s performance to meet speciﬁc system requirements.

Cover

The cover of the pressure reducing valve encloses the upper part of the valve, protecting critical components such as the adjusting screw and spring from external elements like dust, moisture, and debris.

Spring

The adjustable spring is one of the most crucial parts of the PRV. The spring is located above the diaphragm and is compressed or relaxed to adjust the set

pressure. The amount of tension in the spring determines the force exerted on the diaphragm, thus controlling the pressure on the downstream side.

Diaphragm

The diaphragm is a ﬂexible membrane that responds to the pressure differential between the inlet and the outlet. When the downstream pressure exceeds the set value, the diaphragm pushes against the spring, reducing the ﬂow. When the downstream pressure drops, the diaphragm relaxes, allowing more water to pass through.

Filter Mesh

The Series 533 includes an integrated ﬁlter mesh, which ﬁlters out impurities and debris from the incoming water before it reaches the sensitive internal components. This helps to prevent clogging and prolongs the valve's lifespan.

Control Stem

The control stem acts as an intermediary between the spring and the valve disk. When the adjusting screw changes the spring's compression, the control stem transmits this force down to the valve disk. As the control stem moves up or down, it either allows more water to ﬂow or restricts it, which helps ﬁne-tune the pressure output.

Seat and Valve Disk

At the heart of the PRV's control mechanism is the seat and valve disk. The seat is a surface that the valve disk presses against to stop or allow water flow. As the diaphragm moves, it either lifts the valve disk off the seat to allow flow or presses it down to reduce flow, thus modulating the pressure.

Pressure Gauge Ports

For easy monitoring, the Series 533 includes ports where pressure gauges can be attached to measure both upstream and downstream pressures. This allows for easy calibration and troubleshooting of thevalve.

The Caleffi Series 535H: High Temperature Applications

While the Series 533 is designed for standard water systems, the Caleffi Series 535H PRV is speciﬁcally engineered for high-temperature applications, such as hot water systems where temperatures do not exceed 80°C. The basic operation remains similar, but the materials and design are modiﬁed to handle more extreme conditions.

Key Differences in the Series 535H:

Thermally Resistant Valve Body

The valve body of the Series 535H is built with materials capable of withstanding higher temperatures. This ensures that the valve performs consistently in environments where traditional valves would fail.

High-Temperature Diaphragm

The diaphragm in the Series 535H is made from heat-resistant materials like EPDM (ethylene propylene diene monomer) or PTFE (polytetraﬂuoroethylene). These materials can endure high temperatures without losing ﬂexibility or structural integrity, ensuring consistent pressure regulation even under thermal stress.

Thermally Optimised Seat and Valve Disk

The seat and valve disk in the Series 535 are also upgraded to withstand the intense heat of steam or high-temperature water.

Functionality

The choice between the two different types of PRV depends largely on the system requirements. For everyday water pressure management, the Series 533 offers a balance of precision and durability. For high-temperature systems, the Series 535H steps up, providing performance where other valves might fail. Understanding the components of these valves allows engineers to select the best valve for their needs, ensuring long-term efficiency, safety, and reliability.

USING TUNDISHES

Russell Armstrong, the inventor of the hotun dry trap tundish, investigates the regulations and the use of tundishes for unvented hot water cylinders

Understanding G3, H1 and the Water Regulations is crucial for ensuring safety and compliance.They provide important and useful guidance for installers.

Overview of The Regulations

The G3 Regulation outlines the standards for the installation of unvented hot water systems. Document H gives the requirements for preventing foul air from entering the building. The Water Regulations are there to ensure that potable water is protected from contamination.

Larger unvented water heaters are popular due to their ability to deliver a good quantity of hot water. These systems are pressurised, which if not correctly installed can lead to dangerous situations.

Relevant general requirements for installations

Safety Features G3 Regulations stipulate that unvented systems must include speciﬁc safety features to prevent risks i.e. over pressure (PRV) and/or over temperature (T/PRV). Cylinders are therefore factory ﬁtted with such devices.

Expansion Vessels Are essential in managing system pressure and preventing undue stress on the water heater and associated plumbing.

Regular Maintenance Maintenance is essential for safety. It is recommended to carry out regular servicing, including testing safety devices. This is an often overlooked part of the homeowners regime and various industry associations (e.g. Hot Water Association (HWA)) are keen to help promote regular maintenance as part of good practice.

Installation for impaired users The installer should give consideration for people with extra needs in accordance with this clause on page 23, G3:

3.55 Any discharge should be visible at the tundish. In addition, where discharges from safety devices may not be apparent, eg. in dwellings occupied by people with impaired vision or mobility, consideration should be given to the installation of a suitable safety device to warn when discharge takes place, eg. electronically operated

Safety devices found on an unvented water heater and the use of tundishes

Inlet control group (PRV) provides protection from excess pressure coming from the cold main and should be discharged visibly, local to the cylinder.

Combined cylinder Temperature and Pressure Relief Valve (T/PRV) this does the same as above, but also protects the system from excess temperatures.

What must a tundish do?

High temperature (90-95°C), high volume (>16LPM) discharge pipework must be designed carefully. Discharging water at these temperatures and volumes can be very

dangerous. A tundish must be able to cope with the full ﬂow on that particular installation. Good practice would be to carry out a full ﬂow test at time of installation, per the tundish manufacturers recommendations.

The tundish must also provide visibility of any discharging water, both when the water is running and more importantly after the PRV has stopped discharging.

Traditionally the subsequent D2 discharge pipework is routed through the building terminates, in a protected way, outside the building. However, this run of pipework is expensive in materials and extensive in time.

Introducing the Water Regulations and Building Regulation H to the installation

It has now become normal practice to run this discharging water to a local soil pipe. But that introduces the need to comply with the Water Regulations (to prevent contamination) and Document H1 to prevent foul air from entering the building.

This is why you will need to install a dry trap tundish that has a designated “air break to drain”. This type of product provides protection from backﬂow or back siphonage contamination, and the dry trap prevents odours and noxious gasses from entering the building.

PLUMBING & BATHROOMS

How to ensure your chosen dry trap tundish prevents odours

Approved Document H does not speciﬁcally mention the testing of dry trap tundishes but states the following:

Guidance Performance

In the Secretary of State’s view the requirement of H1 will be met if a foul water drainage system:

a)Conveys the ﬂow of foul water to a foul water outfall (a foul or combined sewer, a cesspool, sceptic tank or holding tank);

b)Minimises the risk of blockage or leakage;

c)Prevents foul air from the drainage system from entering the building under working conditions;

Air Tightness

1.38 The pipes, ﬁttings and joints should be capable of withstanding an air test of

The hotun range of products are designed for hot water applications with the installer in mind.

positive pressure of at least 38mm water gauge for at least 3 minutes. Every trap should maintain a water seal of at least 25mm. Smoke testing may be used to identify defects where a water test has failed. Smoke testing is not recommended for PVC-U pipes.

Our recommendation is to adopt the test found in clause 1.38 to ensure that your dry trap tundish is compliant.

All hotun dry trap tundishes are manufactured to this standard and are batch tested to conﬁrm compliance.

Doing a simple compliance test on site is a good idea. The “blow” test (pressurising the D2 outlet connection

side) gives a good indication of air tightness. If you can blow through the tundish then foul air would also be able to escape and it would therefore not be deemed compliant with Document H1, 1.38.

Conclusion

The hotun range of products are designed for hot water applications with the installer in mind to ensure their clients get a compliant installation using just one simple product. Another product in the hotun range is the tundish alarm unit, hotun detect. It ensures that the building user has an early alert to any unwanted T/PRV activity. This alert prevents excess wasted energy and water. A repair can then be made at the earliest signs of problems and at a convenient time to suit all.

PRESS AHEAD

Joining pipe is a daily task for most plumbers and in recent years many have been considering press ﬁttings. Using this method, installers do not have to consider ‘hot works’ and pipes can be connected quickly and with minimal effort. To press the ﬁttings a plumber will require a press tool.

These tools need to be substantial enough to power through the press quickly and light enough for one handed operation. Rothenberger’s ROMAX Compact III is 2.5kg (without press jaw) and at just over 34cm in length has been designed for use in constricted locations. It can press from 15mm to 35mm in copper and up to 40mm in plastic/MLP.

Pressing cycle

The company says the press cycle is achieved in around three seconds with a pressing force or 19kN. The tool features Constant Force Technology (CFT), to deliver constant pressing force over the complete pressing cycle. There is also a new Jaw Locking System designed to secure the jaws in place and enable users to attach and detach the press jaws with ease. The company suggests around 130 presses are possible with a 2.0Ah battery.

Rothenberger has unveiled a new ‘compact’ press tool.

Data driven

Data acquisition is increasingly important across many areas of life and users of the ROMAX Compact III can also beneﬁt from real-time data acquisition of relevant machine parameters and the creation of press protocols directly on site. Both can be achieved via the ROTHENBERGER App. In fact, the ROMAX Compact III is ROTHENBERGER’s ﬁrst smart press machine with Bluetooth connectivity. Via the ROTHENBERGER app, tool and smartphone can be connected, providing the user both machine and press data. Through the App the tool can also be locked.

In the MIDdle

Founded in Sweden in 1975 by electrician Matti Viio, Snickers Workwear is well known for its trade clothing with a catalogue including everything from sweatshirts to socks. Whether it is hot and sunny or cold and rainy – or anything in between – the company has solutions to help tradespeople stay efficient throughout the working day.

With the autumn now upon us, and the British weather turning wet and windy, the right clothing can be the difference between a satisfying and productive working day and a miserable one. A key component to any autumn workwear is the mid-layer.

Providing some protection from the elements – though not as waterproof as outer layers – the mid-layer is key for maintaining a stable temperature. Another key factor is ﬂexibility: with plumbers and heating engineers often stretching, twisting and bending, this layer needs to adapt to different body positions without restricting mobility.

The hood also includes a reflective detail on the front.

With autumn bringing cooler days, a warm and flexible mid-layer can help maintain body temperature and keep the wearer productive whether working outdoors or inside. PHPI takes a look at a recently introduced hoodie from Snickers Workwear.

FlexiWork mid-layer

Snickers Workwear has a large range of options in this area, with some new technical mid-layers launched earlier in the year. We recently got hold of one of the company’s Full Zip FlexiWork Midlayer Hoodies in Blue/Black – although this item is also available in two other colour combinations, Black/Black and Khaki/Black.

The company describes it as stretchy and versatile, allowing freedom of movement during work, and the top does allow a good range of movement. There are two large side pockets which can swallow up a host of items, while creating

two inside ‘pocket bags’ as well. A third pocket on the left chest easily stores a smart phone. All pockets are zipped to keep the contents secure.

The pre-bent sleeves feature thumb loops to keep the sleeves pulled down and wrists covered, while the edge of the hood is elasticated so when it is up, the hood does not restrict visibility. The hood also includes a reflective detail on the front to help others see you in dark conditions. The zippers are also reflective, further aiding visibility.

The hoodie is made of a 2-layer mesh/interlock fabric which on cooler days offers a good level of insulation, keeping the wearer warm even during periods of limited movement.

The main fastening is a two-way zipper at the front, which allows the wearer the ability to open the jacket from both the top and the bottom. This detail can help when accessing trouser pockets or to cool down – a handy feature on warmer autumn days or when working inside.

HIGH PRESS

In the latest video on the PHPI YouTube Channel Chirag from CP Utility Solutions takes a closer look at the >B< Press copper fittings from Conex Bänninger.

Plumbers are showing increasing interest in using press fittings, and over the past few issues, PHPI has looked at some of the equipment available, notably some of the press tools. But what about the fittings? A new video on the PHPI YouTube Channel should help, with Chirag, from CP Utility Solutions, taking a closer look at the >B< Press copper fittings from Conex Bänninger.

In the video he talks through some of the advantages of using press fittings – for example, no hot works permit is required –before looking at the various features and benefits of the Conex Bänninger fittings, which include products that are suitable for gas, and options that are WRAS approved.

Chirag notes: “It is very easy to distinguish between the water and gas fittings. So the gas fittings, obviously, in a yellow packet and it also has gas imprinted all across the back as well. Water fittings come in another clear packaging.”

From a health and safety perspective, you’ve got no risk of flame or explosion – it is flame free. Also, from an engineer’s perspective, you are not having to breathe in the fumes from when you are soldering.

Chirag explains that as long as the ﬁttings are used as per manufacturer’s instructions, installers will get a 25 year guarantee. There is also a training programme available to installers.

Using the ﬁttings

To demonstrate how the fittings can be used, Chirag uses the gas fittings to replace a gas pipe where a leak has been reported – making quick work of the job before doing the required gas safety checks.

Heading inside, he replaces a small section of pipework near a boiler where a customer has reported a leak. During the installation Chirag demonstrates how to spot when a fitting has not been pressed noting: “You can see, with the O ring, it is not completely flooding out. It does give you an indication that there is a leak there.”

It is very easy to distinguish between the water and gas fittings

He then demonstrates how straightforward it is to rectify the issue using a press tool, even while the pipe is full of hot water. Highlighting some of the benefits, Chirag explains: “You’ can press with water in the pipes, with soldering you can’t do that. From a health and safety perspective, you’ve got no risk of flame or explosion – it is flame free. Also, from an engineer’s perspective, you are not having to breathe in the fumes from when you are soldering.”

ADEY INTRODUCES NEW ‘SUPER COMPACT’ FILTER

The MagnaClean AtomSC is the latest addition to ADEY’s MagnaClean ﬁlter range.

The company’s smallest ﬁlter to date, it has been developed with the needs of the speciﬁcation boiler sector in mind. Described as ‘super compact’, the AtomSC has a pipe cut-out of only 60mm. It has been designed for installation in the tightest of spaces; either under, or around the boiler.

Melissa Chamberlayne Product Manager at ADEY explained: “By working alongside key contractors in this sector we’ve been able to understand that one of the key challenges of retroﬁtting boilers and heating systems is installing them in increasingly restrictive locations. The AtomSC aims to address this.”

which is why the new MagnaClean AtomSC comes in a unique Compliance Pack.”

System life

The company says the AtomSC has also been designed with the needs for the life of the system – not just for the installation. With 22mm compression fitment, AtomSC also features filter-to-boiler isolation. By isolating the built-in isolation valve on the filter and at the boiler return, the filter can be drained down and serviced.

A fully removeable ﬁlter canister allows the AtomSC to be cleaned, removing all traces of magnetite and preventing any debris re-entering the system.

Flushing adapter

Available as an optional accessory, the AtomSC also has a flushing adapter making it easy to connect to the system to flush. Compatible with the ADEY MagnaCleanse this allows contractors to save additional time and resources by using less water to re-fill and flush compared to traditional flushing techniques.

The AtomSC is also compatible with the ADEY Rapide® range of fast dose chemicals.

For compliance with BS7593 the AtomSC is supplied as a package including; ADEY MC3+ system cleaner and ADEY MC1+ system protector. Part L compliance can also be achieved by selecting from two further packages containing either ADEY MagnaScale2 or the ADEY ElectroScale2 in-line mains cold water scale reducers.

All packages also include two test strips for the ADEY ProCheck Universal Digital Water Test Kit – results are stored on the ADEY Sense portal so contractors and speciﬁers can rest assured that BS7593 has been adhered to and evidenced.

VIESSMANN INTRODUCESNEW AIR SOURCE HEAT PUMP

Viessmann Climate Solutions UK has launched a new 40kW air source heat pump designed for larger properties, public sector applications and small- to mid-scale commercial installations.

Providing both heating and cooling within a single appliance, the Vitocal 250-A Pro has a Coefficient of Performance (CoP) of 5.32 at A7/W35 (outside air temperature 7˚C and DHW 35˚C).

It is energy rated A+++ for both low and medium temperature applications and uses the natural propane refrigerant R-290, which has a global warming potential (GWP) of 0.02, compared to 1.0 for CO2 and 675 for R-32.

The company says that thanks to its maximum ﬂow temperature of 70˚C, it can be used with existing radiator systems in many cases, making it suitable for larger modernisation projects.

The new Air Source Heat Pump features factory-installed operating and safety devices, along with a weather-compensated remote monitoring and control system designed to ensure operation and maintenance are also greatly simpliﬁed.

“The 250-A Pro stands out because of its looks, its performance and its environmental credentials,” said Viessmann Product Manager, Hugh Jones. “This is a premium heat pump that ﬁlls a gap in the market for a highly efficient, propane solution for larger installations. We have a number of customers lined up who have been waiting for an appliance that can offer this level of quality and efficiency at the scale and price point they need.”

The Vitocal 250-A Pro can be operated in bi- or monovalent modes and requires a three-phase electrical supply. The company says that next year, the facility to cascade up to four units together will be added, to further extend its range of applications.
