Take control
Boilers are the mainstay of the UK domestic heating market, with the majority of homes heated using gas boilers, the most up to date of which have high performance levels. Whilst the replacement of an older model with a more advanced one may well help improve the efficiency of a heating system, in many cases further gains require consideration of other elements in the set-up.
Water quality within the heating system is important and can be improved with appropriate actions and treatment. Equally, poorly performing heat emitters, such as radiators, may need attention or replacing, as may other elements of the system.
However, one part of the overall heating system which warrants examination is controls and, in particular, smart controls. A recent survey by Drayton revealed that 96% of its customers were interested in integrating smart home technology within their homes, which suggests demand for smart heating controls may be on the increase. The attributes of smart heating controls vary, but many offer features designed to optimise energy use – such as personalised scheduling, geofencing, weather adaptation and multi-zone heating.
Additionally, some smart controls also provide users with greater levels of information on how they use their heating system, while some can learn a user’s routine and adapt heating schedules automatically.
Another important factor is the way users interact with their heating system. While a single wall-mounted heating thermostat is familiar, as technology develops, many users seek more flexibility and convenience.
Wireless units can be placed in more convenient locations around a home, but control via smartphone app is now also an important consideration. Drayton’s recent survey revealed that 66% ranked a smartphone app as the most important feature when choosing a smart heating control. Integration with other smart features within a home, including voice assistants, may further user convenience.
With boilers remaining the main source of heating for the majority of homes it is important to consider all the ways to maximise efficiency and convenience whilst delivering warmth, especially important at this time of the year.
Up-to-date heating controls can help users not only feel more connected to their heating system, but also provide efficiencies that help keep costs down, whilst maintaining a comfortable domestic environment.

NEW TRIAL DEMONSTRATES BENEFITS OF HYBRIDS
A new trial has demonstrated how hybrid heat systems can heat homes in the UK while still working towards the country’s net zero goals.
The joint research project between manufacturer Worcester Bosch and University of Salford found that a weighted average of 94% of annual heat demand could come from the heat pump element of a hybrid system.
The research took place at the University of Salford’s Energy House Lab – a full-scale reconstruction of a pre-1920 end-terrace home – and involved a ‘bivalent parallel system’. The heat pump acts as the primary heat source, with the boiler adding supplementary heat when the outdoor temperature drops.
Carl Arntzen, CEO of Worcester Bosch, said: The findings from our work with the University of Salford are clear: bivalent parallel hybrid heat pumps are a practical and highly effective technology for the UK today. We believe government recognition and financial support for hybrid heat pumps, such as including this proven technology in the Boiler Upgrade Scheme (BUS), presents an opportunity to make the transition to lower carbon heating faster, fairer and more effective.”

SURVEY
REVEALSSTRO NG INT EREST IN SMART HOMET ECHNOLOGY
A recent survey undertaken by Drayton has revealed the level of interest in Smart Home technology.
When asked about consumer interest in the technology, 96% of the surveyed installers revealed that their customers had demonstrated an interest in smart home technology. Drayton surveyed heating engineers, electricians, heat pump installers and plumbers about homeowner appetite for smart home technology.
The demand for smart home technology now also expands past just heating controls. Survey respondents reported that outside of heating controls, smart lighting was the most popular element of smart technology, with 56% stating their customers currently have or would be interested in adding this to their home.
When building a complete smart home, other devices such as smart alarms (36%) and a range of sensors, including water leak sensors (13%), window and door sensors (12%), and humidity sensors (11%), were also found to be of interest or already present in homes.
Nick Hunt, UK Sales and Marketing Director at Drayton, commented: “The results of our survey emphasise that the needs of customers are continuing to change in line with the evolution of technology. Tradespeople need to be well-equipped to match these demands by offering a reliable system that simply incorporates a variety of smart home technologies as they become more prevalent in homes.
“The research highlights the opportunities available to installers through the growing interest in smart home solutions and with systems like Wiser 2nd Generation, installers can confidently offer their customers the means to a seamlessly smarter, more connected home.”

We are in a pivotal time for the UK heat pump market which has shown strong growth over recent years, and it’s time to stand together to collectively navigate the future of heating in the UK.”
CARRIER SOLUTIONS UK EXPANDS TRAINING NETWORK
Carrier Solutions UK has officially opened its fully refurbished London Colney training centre. The company says the move marks the next step in the company’s nationwide investment in dedicated HVAC engineer training.
The enhanced and extended facility will deliver education and hands-on experience with Carrier Solutions UK’s latest innovations and new equipment, ensuring engineers can access training across the country.
“The refurbishment of our London Colney facility reflects our ongoing commitment to supporting both cooling and heating engineers with the very best training environments, no matter where they are in the UK,” said David Dunn, Managing Director, UK&I, Carrier CSE-R Europe.
AREINSTALLERS WARMING TO HEAT PUMPS ?
More than half (59%) of UK heating engineers are either already or likely to work with other companies to develop heat pump competencies, according to heating and hot water solutions provider Baxi’s fourth annual Installer Skills Survey.
However, a lack of consumer demand remains the number one barrier to heat pump uptake – with 60% of installers citing this as the main barrier. The 2025 Survey also showed that attitudes of some segments of the heating engineer population are becoming more sceptical of heat pumps and towards net zero more broadly. The survey – conducted with green supply chain consultancy Talan (formerly Gemserv) – gathered responses from almost 400 installers.
The study found that 59% of installers are either already developing the skills to fit heat pumps or intending to do so within the next few years.
The number of installers citing a lack of training as a barrier has fallen by 18 percentage points compared with 2024,
suggesting that industry investment in training is beginning to pay off. Baxi says that it has seen over 1,000 installers attend its own heat pump training courses over the last 12 months.
Work motivation
When asked what drives them in their work, heating engineers most frequently cited providing a good service to customers (85%), solving technical problems (62%), and getting things right from a technical perspective (50%). According to Baxi, this sense of professionalism partly explains why some installers hesitate to recommend new technologies until they feel fully competent.
“Installers clearly want to do the right thing for their customers,” said Ian Trott, Head of Training at Baxi UK. “Many take pride in their technical ability and won’t compromise on service until they’ve built real hands-on experience with the technology. Training for a qualification is one thing – but training for competence is what’s really needed to move the needle on installer engagement.”
Lack of consumer demand remains a barrier to heat pump uptake, according to the 4th annual Baxi Installer Skills Survey.
Hybrids – a practical bridge
The 2025 survey also found that 35% of installers have or would be somewhat or extremely likely to move to fitting heat pumps as part of a hybrid system, where a heat pump works alongside an existing combi boiler, rather than as a full heat pump only replacement. Unlike a stand-alone heat pump system, hybrids typically do not require a water cylinder making the installation lower cost, quicker, less disruptive.
“Hybrids can be a powerful transitional step,” Trott said. “They are often more attractive to installers because they’re easier to fit, and to customers because they require less cost and disruption. Research shows a well-installed hybrid can cut a home’s heating carbon footprint by around 70% a year or more. Supporting hybrid options would give more installers valuable real-world experience and help homeowners see the benefits earlier.”

Paperwork – an obstacle
While attitudes to heat pumps have shifted positively, consumer demand is developing more slowly. Although many households continue to prefer a straightforward like-for-like boiler replacement, 2024 was still a record year for UK heat pump sales.
Almost half of respondents – 46% –named the paperwork involved in government schemes as a major obstacle to installing heat pumps.
Baxi says it will launch its own MCS Umbrella scheme later this year, designed to reduce the administrative workload for smaller businesses and sole traders. The company has also expanded its hands-on training programme and increased online and video-based educational resources produced at its Warwick Solutions Academy.
Generational divide
A recurring theme in Baxi’s annual surveys has been a generational divide in attitudes
Supporting hybrid options would give more installers valuable real-world experience and help homeowners see the benefits earlier
to retraining. Installers approaching retirement are generally less inclined to invest in developing new skills, while those earlier in their careers are more open to diversifying their expertise.
The survey also noted that a large proportion of UK heat installers work either as sole traders or in very small teams. This structure can make it more difficult for them to take time out for training or to manage the additional paperwork that often accompanies low-carbon installations. Many respondents said they
expect to collaborate or partner with other service providers to meet future demand for clean heat technologies.
“These findings show that despite some hardening of opinions most gas boiler installers aren’t dogmatic about technology and just want to do a good job for their customers.
“Many installers are preparing for the future, with plans to prepare for the uptake of heat pumps and develop their skills. As a result, more installers are comfortable talking to their customers about energy efficiency and fewer say that training is a barrier than in last year’s study. It shows that the work the sector is doing to encourage training is working,” said Will Taylor, Principal Consultant at Talan.
*Almost 400 installers took part in Baxi’s 2025 survey, which was conducted in July and August 2025.

PROFILE
WARMFLOW
Warmflow is a leading heating appliance manufacturer with a portfolio of solutions spanning Liquid Fuel Boilers, Warm Air Heaters, Ground Source Heat Pumps, Cylinders and Air Source Heat Pumps. Based in Lisburn, Northern Ireland at its 150,000 square foot facility, the company is well known throughout the region and is expanding across the UK. In fact, its reach goes right around the world, with customers across Europe and as-far-a-field as Canada, New Zealand and the Falkland Islands.
The company is also expanding closer to home, with its GB facility, currently in Telford, soon to be replaced as it moves operations to Shrewsbury and a larger site, all part of a multi-million pound investment.
Heating focus
Established in 1968, as Castlereagh Sheet Metal, over its history the company has manufactured everything from gun cabinets to metal urinals, but for some time Warmflow has focused on heating appliances and is particularly known for its oil boilers.
PHPI heads to Northern Ireland to tour Warmflow’s HQ & manufacturing facility in Lisburn, discover more about the company’s roots and to take a look at its latest heating solutions for the UK market and beyond.
Seven years ago the company completely redesigned its oil boiler introducing a new range called Agentis. Brian Beattie, Director of GB Sales and Marketing at Warmflow, said: "When we re-launched the Agentis oil range, it was completely a radical change, not just an evolution, it is completely different, the size is different, where the components are is different, everything about it is different.”
The move delivered a robust appliance and reduced warranty issues substantially. Since then, the range has been modified and improved. Warmflow includes a number of additional items with the Agentis boiler that installers often need to source separately. Included is a filter, oil valves,
pressure reducing valve and shock arrestor. Within the Agentis range there is also a PRO version with further options. The moves are designed to assist installers as much as possible, reducing complexity and installation time.
Renewable future
With the market moving toward Low Carbon Heating solutions the Agentis Liquid Fuel range can be run on HVO (Hydrotreated Vegetable Oil), a renewable fuel which can be used as a replacement to oil. Neil Rumbold, GB Renewables Manager at Warmflow described HVO as, “a game-changer”.
However, to offer consumers and installers a broad range of renewable heating options the company has also brought to market both Ground Source Heat Pumps and Air Source Heat Pumps (ASHP), together with Heat Pump Cylinders. The company’s Zeno R290 ASHP comes in three sizes, 9, 15 and 22kW all of which fully modulate. The R290 refrigerant has a low Global Warming Potential (GWP) of three and can heat water up to 75°C. It has a sleek anthracite finish and sound levels as low as 41dB.
A helping hand
Shifting to installing Heat Pumps can be a daunting prospect for some installers. To help Warmflow has 10 training locations across the UK to help provide installers with the required knowledge.
Additionally, it provides its ‘Heat Pump Assist+’ programme, which uses an MCS umbrella scheme to help installers deliver a MCS accredited installation without the need to be MCS accredited. Brian Beattie noted: “the umbrella company, working with us, will do system design, on-site support, onsite commissioning, holding [an installer’s] hand right from start to finish.”
Take control
To help installers commission, service and maintain its Zeno Heat Pumps the company has developed Warmlink. Via a SIM card, which has a five-year SIM plan and can be extended at the end of the period, Warmlink provides engineers with control of the heat pump. Neil Rumbold noted:
We are constantly innovating and moving our products forward
“You got full operation of the heat pump. It is more for the installer and our tech support rather than the end user.”
He continued: “There is a read only setting, a service engineer setting and a senior service engineer setting. You can have full remote diagnostics. As long as there is power to the unit you can do everything from there.”
Using the remote diagnostics, issues or faults can be investigated prior to a support visit, saving time for installers, and especially journey time which can be significant issue in rural areas.
Hot water
Supporting the company’s Heat Pumps is the Nero range of Heat Pump Cylinders with sizes from 170L to 290L. The cylinders come pre-assembled, are made from duplex stainless steel and are MCS compliant. Nero Heat Pump cylinders are slightly different from some other cylinders as they don’t have a coil. Neil Rumbold explained: “Normally you’d have a coil in the cylinder to give you the water temperature. We use a heat exchanger on the side and a shunt pump. So that pump moves the whole body of water and you get really fast recovery.”
Stay connected
To further support installers the company also has a loyalty programme, Warmflow Connect. Neil Rumbold explained the scheme, “helps to get products registered, it activates guarantees, plus there are other goodies on there.”
He explained how one customer recently got £200 vouchers for a well-known coffee shop. These were split across a number of cards and passed out to fitters across the company, who could then get ‘free’ coffee in the morning on the way to a job.
Well placed
With a new GB facility under development and a large range of low-carbon heating appliances, including both ground source and air source heat pumps, Warmflow is well placed to support installers looking to specify and fit a range of heating solutions.
Summing up
Warmflow’s position Brian Beattie said: “We are constantly innovating and moving our products forward. We only use premium market leading components and we have a great sales support teams.”

RURAL WARMTH
Malcolm Farrow, Director of Marketing and External Affairs at OFTEC provides some thoughts on the Warm Homes Plan and the possible impact on rural communities.
The Warm Homes Plan was expected to be a landmark publication which set out the overall policy direction for decarbonisation. Originally expected by the end of October, it’s now delayed until at least the Chancellor's Budget on 26 November.
This isn’t just a rescheduling – it's a sign of the policy and financial pressure the government is under. So where does this leave the off-grid sector? Whilst the Warm Homes Plan hasn’t been published, here are three things we have learned.
Cost pressures
The most immediate cause for the delay is widely speculated to be internal discussions over the costs involved. Since coming to power, Labour has committed to electrification, but the dream of delivering this has hit financial reality.
This is particularly true in the off-gas grid sector, and we’ll overlook for now the huge costs required to upgrade the electricity grid itself. We know these buildings are typically older, draughtier, and often require significant upgrades, from enhanced
we will continue to work positively with the government because we share the ambition to transition the off-grid sector onto low carbon heating
insulation, new radiators, and pipework, before a heat pump can run efficiently.
This means the upfront cost burden can be significant. Even with the Boiler Upgrade Scheme, which offers a £7,500 grant to install a heat pump, households face considerable cost, and heat pumps aren’t coming down in price either.
To drive uptake, the government could look at increasing the value of the grant but this would be expensive when the Treasury is already struggling to balance the books and is facing increasing economic headwinds. Another idea that has been mooted is offering electricity discounts to households who install a heat pump. However, data suggests both of these subsidies would benefit many wealthier households who can afford to top up that initial cost. This leads us onto the second problem.
Political risk
Beyond the cost to the Treasury, there is a clear concern about the political risk of imposing electrification on off-grid households. We’ve already seen the government get into difficulties over the past year with attempted changes to the winter fuel payments and inheritance tax for farmers, both of which have impacted rural areas.
With more Labour MPs representing rural seats, many on very tight margins, this is a political fight many don’t want to engage in. Particularly when it comes to something as personal as people’s homes.
The fundamental problem is, again, the cost implication for consumers. According
to the latest Ofgem report for 2024-25, quotes for installing air source heat pumps were typically between £10,001 to £12,500. However, the average total amount when applying for grants through the Boiler Upgrade Scheme was higher at £13,433. This means many households who claim the £7,500 grant would still have to pay thousands more on top.
The vast majority of constituents don’t have that kind of disposable income. With rising food prices and inflation creeping up again, consumers can’t be expected to stump up the cost of electrification as well.
Off-grid policy reset
The government is committed to electrification and heat pumps, yet they are aware of the affordability and logistical obstacles this presents for many households. It’s only by offering large subsidies that any real progress is possible and why a reset in off-grid policy thinking is desperately needed.
Let’s be crystal clear what this means though. There is nothing inherently wrong
Malcolm Farrow, Director of Marketing and External Affairs at OFTEC
with heat pumps. We should absolutely not turn our back on the technology. For many more modern homes, they are a viable solution and should be advocated for. However, this is not a one size fits all solution. The challenges of installing the technology in older off-grid homes is clear and, unless prices fall dramatically, heat pumps will remain out of reach of most households.
That’s why we’ve been advocating policy support for renewable liquid fuels such as Hydrotreated Vegetable Oil (HVO). If we start with a blended fuel there is no upfront cost to the consumer but we immediately see a significant cut in carbon emissions. The government already has the legislative powers to introduce a market mechanism similar to that in transport.
Combine that with a simple change of the Hydrocarbon Oils Duties Act, to equalise the duty applied to renewable fuels with that of kerosene, and the introduction of a renewable liquid fuel blend at similar cost to kerosene becomes a reality.
Continued indecision is bad for consumers, technicians, fuel distributors and businesses. How can any of us plan ahead and think about future investments when we don’t know what policies will be in place. Whilst we are disappointed with the delay to the Warm Homes Plan, we will continue to work positively with the government because we share the ambition to transition the off-grid sector onto low carbon heating.

we’ve been advocating policy support for renewable liquid fuels such as Hydrotreated Vegetable Oil (HVO). If we start with a blended fuel there is no upfront cost to the consumer but we immediately see a significant cut in carbon emissions
Selec tion TIME
With a growing variety of radiators on the market, Chris Harvey from Stelrad Radiators, outlines just five of the options available to installers when considering which to select.
When it comes to radiators, over time the landscape has changed hugely. Today there is a wide choice when it comes to design, colours and styles for both homes and commercial premises. Additionally, radiators have changed from simply heating appliances to becoming a part of the décor – and in some cases they can form the focal point of rooms.
Here, we take a closer look at five of the radiator options available – K3s, verticals, designer radiators, electric radiators and cast iron radiators.
Increasingly, homeowners are wanting a say in the radiators in their
homes
K3s
K3s have become increasingly popular with the rise of renewable heating systems. Low temperature heat pump systems will need larger radiators than traditional boiler driven systems – or radiators with a higher heat output. K3s feature three panels and three sets of fins – so 50% more heat sharing metal surfaces than the same size K2 radiator –ensuring the right level of heat sharing to provide comfort heating in the home –without enlarging the radiator footprint. K3s are also suited to providing that additional heat often required in that cold room in the home that you can never seem to get warm. Perhaps in the conservatory so you can sit out there right through the winter - the additional oomph that K3s offer can transform the comfort levels and bring areas of the home back into use in the colder months of the year.
Verticals
No longer just the traditional horizontal radiators around the home, you can select different width and size vertical radiators to fit nooks and crannies around particularly older homes. Also in hallways, landings and spaces in smaller rooms where you are limited with the size of horizontal radiator you can use.
Vertical radiators in a wide number of colours can be the perfect match or contrast in kitchens and bathrooms and as feature radiators in any room in the home. Increasingly, homeowners are wanting a say in the radiators in their homes and are going for mix and match selections around the house.
Designer radiators
The best-selling radiators today are still the Compact panel radiators – because today modern Compacts are exceptionally good looking and highly effective at heating around the home, with attractive top grills and side panels.
The Compacts from Stelrad also feature as the ‘hidden’ heating source on a number of their designer radiator options for their popular Vita range – that feature different style casings. Flat casings for the Plan style, and vertical or horizontal striped casings for Deco and Silhouette designs of ‘designer look’ premium panel radiators.
Electric radiators
The newest range of radiators available from Stelrad is the electric range – suited to off-grid homes where gas isn’t an option and for people who simply prefer an electric home. The range is currently made up of 13 steel and aluminium radiators and towel radiators.
There is clearly a significant marketplace for ‘all electric’ heating in homes, despite the domination of gas boiler fired heating systems, and we’ve seen major interest from people adding extensions or conservatories to their homes, where they see the advantages of an electric radiator, rather than extending their existing heating system.
Cast iron radiators
Traditionally Stelrad has supplied steel radiators and continues to do so with more than two and a half million radiators manufactured each year. But in the past few years, Cast Iron Column radiators –which were first around in Victorian times –have come into vogue again and so it has added a selection of Cast Iron Column radiators to its range.
The new Stelrad Cast Iron Column radiator is available now and adds undoubted charisma to any modern or period home with its distinctive, ageless look and its Natural Cast finish.
With the added options of either Antique Brass or Brushed Nickel TRVs to provide modern heating control, the classic, contemporary design suggests a genuine piece from yesteryear.
These radiators are floor standing with in-built feet for extra stability as they are significantly heavier than their steel counterparts. They are available in two heights and a wide variety of widths – a total of 96 sizes currently available.

UPSKILLIN
LOW-CARBON TECHNOLOGIES
With the heat pump market expanding every year, there are growing opportunities for heating engineers. James Hodgson, National Training Manager for Ariston, explores how heating engineers can upskill and examines the benefits of doing so.
The heating industry is in the middle of one of the biggest and quickest transformations it has seen in decades.
As governments, businesses and households race to hit net-zero targets and cut carbon emissions, traditional gas systems are steadily giving way to heat pumps, hybrid systems and other low-carbon alternatives.
For heating engineers and installers, this shift can signal a huge opportunity as customers increasingly look for installers they can trust to deliver energy-efficient systems that meet modern standards. So how can installers upskill and what are the wider benefits of doing so?
The Upsides of Upskilling
One of the biggest benefits to upskilling is a future-proof career. As gas boilers are phased out and bans on new fossil fuel heating are already planned, upskilling in heat pump technology keeps skills relevant – and careers secure – as the industry evolves. According to data from MCS, there were 44,564 MCS certified
installations of air source heat pumps across the UK between January –September 2025, up 9% compared to the same period in 2024. This growing interest can in large part be attributed to initiatives such as the Boiler Upgrade Scheme, which provides funding when replacing a gas boiler with renewables like heat pumps.
Currently, the UK remains legally bound to reach its net zero target by 2050, which means the uptake and installation of renewable technologies such as heat pumps is only going to increase further. With this in mind, engineers who can install these renewable technologies will remain in demand long after traditional heating skills have become less relevant.
Installers who upskill early and demonstrate their certified expertise could command premium rates for their abilities later down the line, especially in a market where the widening skills gap remains a crisis. This in turn could translate to larger contracts, repeat business and access to higher-value projects.
Training requirements
As the front line of delivering low-carbon heating installations, heating engineers have a responsibility of helping customers choose the right solution, so it is important they are well-versed in delivering this type of work and answering any questions the homeowner might have.
It is advised that qualified gas engineers attend training with a heat pump manufacturer, such as Ariston, to ensure they are well equipped with the knowledge required to successfully install the technology.
Manufacturer training, such as that offered by Ariston at its training centres across the UK and Ireland, often covers a mix of theory and practical work, closely examining the key differences that heating engineers need to be aware of between a typical gas boiler and heat pump system. This will include proper system design, the importance of heat loss calculations, and how to correctly commission and maintain the unit.
Many heat pump installers also choose to obtain MCS certification, as this unlocks a number of benefits. This can help them stand out in a competitive market, elevate their business and boost their reputation.
As with any long-term investment, heat pump installation can be costly, so homeowners looking to make significant investments in upgrading their heating systems will be more likely to choose a certified installer that not only meets industry standards and regulations but will get things done right the first time.
Additionally, government-backed incentives and grant schemes – such as the Boiler Upgrade Scheme – also require installations to be carried out by a certified professional, meaning those without the appropriate accreditation risk excluding themselves from a rapidly growing segment of the market.
By upskilling and gaining the relevant certification, professionals are not only securing their futures but also giving themselves a competitive edge
Seizing the opportunity
With the transition to low-carbon heating already underway, the heating industry is changing fast and significant opportunities are being created. By upskilling and gaining the relevant certification, professionals are not only securing their futures but also giving themselves a competitive edge in a time when demand
for expertise is outpacing supply.
It also allows heating engineers and installers to contribute directly in the transition to net zero. For those who are passionate about tackling climate change and environmental conservation, upskilling into low-carbon heating systems means they can be part of the change as we transition into a more sustainable world.
The need for trusted professionals who can deliver efficient, sustainable heating solutions is fast-growing and for those ready to adapt Ariston looks forward to helping installers boost their professional development and become part of the skilled workforce leading the way to a cleaner, greener future.
MINIMISE DISRUPTION
Rick Clarke, Product Manager, NIBE Energy Systems Limited, investigates how exhaust air heat pumps may be winning over installers.
For installers, the race to decarbonise new homes isn’t just about adopting new technologies; it’s about finding solutions that are practical to fit, easy to maintain and deliver the performance developers need. In urban areas where outdoor space is tight and aesthetics matter, the options can quickly narrow. That’s why exhaust air heat pumps (EAHPs) are gaining ground across the UK. Compact, all-in-one and designed to work without any external units, EAHPs are emerging as one of the most efficient ways to deliver low-carbon heating, ventilation and hot water in new-build and retrofit settings alike. For many developers and housing associations, they’re solving both a regulatory and a practical design challenge in one.
How they work
Unlike traditional air source heat pumps, EAHPs recover heat energy from the warm, stale air extracted from kitchens, bathrooms, and utility rooms. This energy is upgraded through the heat pump to provide heating and hot water. The cooled air is then discharged outside, ensuring good indoor air quality.
Because they harness indoor energy,
EAHPs maintain consistent performance year-round, regardless of the weather, and this is a key benefit for developments where reliability matters. Integrated ventilation ensures compliance with modern building standards, making the system a natural fit for low-energy homes.
the all-in-one nature of EAHPs means faster installation, no external plant and fewer on-site complications
EAHPs are particularly well suited to new-build apartments and multi-residential schemes, where space is often limited and energy performance targets are high. They’re also a strong option for smaller, well-insulated homes that require efficient, compact heating solutions.
In retrofit projects, EAHPs can be installed often with minimal disruption, making them an attractive choice for housing associations and developers looking to decarbonise existing properties.
More broadly, they support developments aiming to meet low-carbon and energy performance standards without the need for complex system designs. For installers, the all-in-one nature of EAHPs means faster installation, no external plant and fewer on-site complications, all helping to keep projects on time and on budget.
Why
EAHPs?
● Lower carbon emissions: By drawing energy from indoor air, EAHPs reduce reliance on fossil fuels and support decarbonisation targets.
● High efficiency: Consistent performance throughout the year, even in colder months, helps keep running costs down.
● Compact, all-in-one design: No need for external condensers or plant rooms, making installation simpler and space requirements smaller.
● Improved indoor air quality: Integrated mechanical ventilation maintains fresh, filtered air while recovering heat that would otherwise be lost.
● Future-ready: Designed to help new homes meet the Future Homes Standard and other low-carbon building requirements.

A new generation
Models like the NIBE S735C offer a balance of performance and practicality, combining efficient heating, hot water and ventilation in a single, space-saving unit. With Quiet Mark certification for low noise levels, a compact installation footprint and a SCOP of up to 4.6, the S735C is well suited to dense residential settings such as apartments and multi-dwelling developments.
The S735C reflects the growing role of EAHP technology in the UK’s low-carbon housing landscape. For installers, systems of this type simplify on-site delivery as there is no external plant, faster installation and fewer coordination challenges.
An example of EAHP technology at scale can be found at Royal Winchester House in Bracknell, a residential development comprising 337 one- and two-bedroom apartments. Each apartment is fitted with a NIBE F730 exhaust air heat pump, providing heating, hot water and ventilation from a single compact unit installed within a service cupboard of around 0.6m². This approach eliminated the need for an external plant, preserved the clean architecture of the building, and supported compliance with Parts L, F, and G of the Building Regulations.
To demonstrate how the technology continues to evolve, one of the apartments was upgraded with the newer NIBE S735C, showcasing how next-generation EAHPs can deliver even higher performance, lower sound levels and smart connectivity. Together, the original installation and the show apartment highlight how EAHPs can scale effectively while adapting to changing regulatory and design requirements.

INSIDE A THERMOSTATIC RADIATOR VALVE
Ed Morris, Technical Manager at Altecnic, takes a look inside a TRV to see how it works.
TRVs provide a straightforward and reliable way to boost both system performance and customer comfort
Thermostatic Radiator Valves (TRVs) are one of the simplest ways to give heating systems automatic temperature control, offering both user comfort and energy saving.
What does a TRV do?
A TRV automatically adjusts the flow of hot water into a radiator based on the temperature in the room. As the temperature changes, the valve opens or closes to maintain a set level of warmth. This means radiators don’t constantly run at full heat, helping to keep rooms comfortable and avoid wasted energy. It also provides frost protection, the Ecocal™ TRV, for example, has a setting that keeps the temperature at around 7 °C to prevent pipes freezing in cold weather.
cross-section
How it works
The TRV is made up of two main parts: the thermostatic head (which senses the room temperature) and the valve body (which controls the flow of hot water). These parts work together automatically.
Thermostatic Head: Internal Mechanisms
Sensor Element
At the top of the valve is the thermostatic head. Inside it is a sensor element filled with a special liquid or wax.
● When the room warms up, the liquid expands
Basic diagram of the Ecocal™ TRV
Detailed
diagram of the Ecocal™ TRV internal mechanisms
● This pushes down on a small pin, gradually closing the valve
● When the room cools, the liquid contracts and the pin moves back up, allowing the valve to open again
This simple expansion and contraction process means the valve is constantly adjusting itself to maintain the chosen temperature.
Obturator & Pin
Between the sensor and the valve body sits the obturator, a small component that transfers the sensor’s movement into a smooth, controlled push on the pin.
The pin is the part that physically moves in and out of the valve body. When pushed down, it restricts the flow of water. When released, a spring pushes it back up, opening the valve. This mechanism
ensures accurate, smooth operation without sticking or sudden changes.
Valve Body: Internal Mechanisms
Hot water from the heating system enters one side of the valve and flows through to the radiator. The path travelled by the water is controlled by a disc connected to a spindle and spring.
● When the pin is pushed down (room warming up), it presses the spindle and disc towards the valve seat, reducing flow into the radiator
● When the room cools, the spring pushes the disc back, opening the valve and letting more hot water through
This setup allows the TRV to modulate flow, not just switch on or off, giving steady temperature control.
Customer comfort
For installers, TRVs provide a straightforward and reliable way to boost both system performance and customer comfort. By automatically regulating radiator output based on room temperature, they ensure each space maintains the right level of warmth without constant manual adjustment. This not only improves the overall efficiency of the heating system but also helps homeowners reduce energy bills and avoid overheating rooms unnecessarily. For
BOOST HOME EFFICIENCY
explains how this can be achieved.
Heating engineers are increasingly being asked to deliver heating systems that are both efficient and cost-effective, while still maintaining the comfort levels that are expected by homeowners. However, now that boilers are already operating at peak performance, simply switching them out is no longer the most effective way to improve efficiency. As a result, for many homes – especially those that already have relatively modern boilers –additional energy savings will come from how the system is controlled. For instance, smart heating controls can help installers and their customers to reduce energy use from existing heating systems without compromising on comfort.
Why upgrade?
Research from BEAMA revealed that upgrading a basic Class I room thermostat to a Class V heating control can reduce energy usage by up to 12%. BEAMA field trials also found that replacing a standard thermostat and programmer with a smart programmable thermostat reduced gas usage by around 5%, which demonstrates the impact that smart controls can have.
By optimising how and when heat is provided, smart controls ensure the boiler only operates when necessary. So, what efficiency-improving features do smart controls consist of?
Multi-zone heating
By dividing a property into zones or individual rooms, each with its own temperature control, homeowners can avoid wasting energy through heating unoccupied areas of the home.
With advanced systems like Wiser and the Wiser Home app, room-by-room heating control can be easily managed via a smartphone app which allows users to modify the temperatures of each room to suit their comfort levels and reduce wasted energy. Multi-zoning capabilities allow for simple, convenient, and highly efficient management of the homeowner’s heating system and are ideal for multi-generational households. Through reducing wasted energy, BEAMA data shows that through multi-zoning alone in a property, can deliver up to 19% savings on energy bills.
Smart modes
Many smart controls also include intelligent operating modes that adapt to homeowners’ routines and the environment.
Smart modes, like Wiser’s Eco Mode or Away Mode for instance, contribute to enhancing a boiler’s performance which leads to further energy savings. Its Eco Mode combines optimum stop and weather compensation to learn the thermal properties of the home. Using this information, it automatically turns the boiler off earlier while still maintaining the desired temperature. Away Mode is another energy-saving feature, which
enables homeowners to turn off their heating when they leave the house without having to adjust their regular schedule.
Research among Wiser users has shown that utilising these smart modes can reduce energy use by an average of 16%, without impacting the comfort of their home environment.
In addition to offering intuitive control, some smart systems provide homeowners with useful insights into how they use their heating.
Taking the Wiser Home app for example, this includes an Insights feature that allows users to track internal and external temperatures, view heating patterns, and identify potential areas for optimisation. When paired with a smart meter, Insights+ provides more analysis which includes real-time energy use, spend tracking, and heating predictions.
These insights enable homeowners to make informed decisions about their energy usage to enhance the efficiency of their heating system. Research shows that using data insights when connected to a smart meter can deliver an additional 7% in savings.
...insights enable homeowners to make informed decisions about their energy usage to enhance the efficiency of their heating system
Investing in efficiency
Through a combination of all the elements discussed here, a smart heating control system like Wiser can make a total saving of up to 30% on a household’s energy consumption. So, for heating engineers, recommending smart controls offers an opportunity to add value for their customers by improving system performance without the need for major, costly appliance upgrades. With boilers already operating at excellent efficiency, smart controls are the next step to leading homeowners to boosted efficiency and a reduction in wasted energy.
Additionally, recent research by Drayton revealed that 96% of its customers were interested in integrating smart home technology within their homes, suggesting demand for products such as smart controls will continue to increase.
The survey also revealed that 66% ranked a smartphone app as the most important feature when choosing a smart heating control, 50% selected multi-zoning capability, and 48% said energy saving features, such as smart modes. Therefore, as well as being important due to their efficiency-improving benefits, choosing a smart heating control that provides these features will also help fulfil customer demands.

THE LOW DOWN
With the end of 2025 approaching, PHPI takes a look back at some of the themes from the last 12 months
This year there have been a wide range stories across the Heating & Plumbing sector, but time and again it was Low Carbon Heating, and in particular Heat Pumps, that came to the fore.
Whilst there were far more boilers fitted in 2025 than Heat Pumps, in the UK the technology is gradually gaining a foothold. A survey by Baxi, covered in more detail on page 12 of this issue, found that 59% of installers are either already developing the skills to fit heat pumps or intending to do so within the next few years.
Over the last 12 months manufacturers of Heat Pumps and ancillary products have continued to develop their offerings. This not only includes products, but also training and wider support programmes.
One initiative making headlines was the news of a trial scheme in Scotland called ‘Start at Home’ which saw a number of installers being given heat pumps for installation in their own home. The scheme reported that the move increased confidence, technical knowledge, and the willingness of installers to embrace low-carbon technologies. It is now being
extended into England and Wales with a number of manufacturers taking the scheme forward – one, Grant UK, has introduced the ‘Start with Grant’ scheme.
Loyalty schemes
Throughout the year, manufacturers have been enhancing their customer loyalty schemes and promotions. One notable move came from Vaillant and Glow-worm, with the heating manufacturer combining its loyalty schemes for each brand into a single programme. Launched in September, myREWARDS took the place of the existing Vaillant Advance and Glow-worm Club Energy loyalty schemes.
Another heating manufacturer reinvigorating its loyalty scheme this year was Worcester Bosch, which introduced VAULT. The new programme has the same loyalty levels (Worcester Bosch Installer, Worcester Bosch Accredited Installer and Worcester Bosch Accredited Partner) and the company says installers can now level up by fitting a range of multi-technology heating products such as oil or gas boilers, air conditioning units and heat pumps.
Loyalty schemes, of course, are not just for the heating market. Earlier this year, Aqualisa introduced Installer Connect designed to “recognise, reward and support” installers fitting the company’s solutions. Meanwhile, in the summer, drainage and plumbing manufacturer Wavin launched a new installer network designed to provide practical and technical support for underfloor heating, ventilation, and heat recovery installers. A number of other companies launched or enhanced loyalty schemes and promotions during the year too.
Training opportunities
One strand running through many of the schemes, and beyond, is educational opportunities. Online courses, webinars and more tailored training can help installers maintain existing skills and learn new ones, something particularly important for those looking to incorporate new technologies.
Throughout the year, a number of training resources were introduced or enhanced. At the beginning of the year Ideal Heating announced an expansion to its Expert Academy On Demand platform, in May Stiebel Eltron expanded its training centre, whilst in June there
Grant introduced the ‘Start with Grant’ scheme in 2025
The Grant eLearning Academy
A number of loyalty schemes were launched in 2025
was the news of Grant’s Aerona 290 course becoming available online via the Grant eLearning Academy.
Among many other developments in training, this year also saw the expansion of Pump School, an in-classroom training program run by Grundfos in partnership with Resideo and Fernox.
On the road
Manufacturers were also hitting the road throughout 2025, reaching out to
installers in demo vans and training vehicles while also attending trade shows across the country, such as the regional Toolfair event which once again visited six venues across the country bringing products and solutions closer to installers. For more details on how to visit Toolfair, which will be heading to a new venue in 2026, please www.rdr.link/pbv015
Through trade shows, expanded training and loyalty schemes many companies have been getting closer to installers. Whether this trend will continue through 2026 remains to be seen. However, whatever the latest news and developments are in the coming months, we’ll keep you up-to-date through the weekly newsletter, the website, and in the pages of PHPI.
EXPERT INSIGHTS
Throughout the year we’ve been making sure installers receive insights from a wide variety of experts across the industry. Amongst the highlights Altecnic took a look at PRVs, covering why they’re essential, how they function and how to select, install, and troubleshoot them. Other highlights include a look at the importance of pressure maintenance and a look at Thermal Stores, and how they differ from a standard cylinder.
We have also looked at ways to improve boiler efficiency, how to benefit from auto-balancing TRVs and provided an insight into ASHP commissioning. Plus, in the summer, there was a look inside an Automatic Air Vent to explain where to use one and how it works.
To explore these and other stories you can access back issues through the PHPI website. www.rdr.link/pbv017
KEEP WATCH
Over the past 12 months a variety of new videos have been added to the expanding PHPI YouTube Channel. Among the videos that have landed in the past year include one on the installation of a Zilmet Intafil Expansion Vessel, there has been a look at Wavin’s Hep2O Keyless push-fit fittings, a review of the Ridgid RP251 Press Tool and a video on the fitting of an ActivFlo Water Conditioner.

Designed to make replacements faster and set-ups easier, Grundfos introduced its new GO range, including the UPS4 GO and ALPHA2 GO circulating pumps. The company says the GO range is “a game-changer" for both integrated and stand-alone circulator pump installs and replacements. One of the features of the ALPHA2 GO is its ability to facilitate quick replacements of post 2015 integrated pumps while the UPS4 GO remains the company’s solution to replace pre-2015 integrated pumps. The company says this means that installers can carry fewer models in their vans, reducing inventory and simplifying the replacement process.
Installers can use the Grundfos GO App to rapidly identifies the correct replacement model. The company says that this eliminates guesswork and ensures the right pump is selected — whether replacing a legacy UPS or a newer UPM3/UPM4 model. The Grundfos GO app is available for free on iOS and Android.

ALTECNIC Caleffi eCAL
In the middle of the year Altecnic launched the Caleffi eCAL®, an electrolytic anti-scale device designed to combat limescale caused by hard water. The Caleffi eCAL® is an inline electrolytic treatment device that prevents limescale formation without altering water chemistry. The company says It works by using a low-voltage electric field to convert calcium and magnesium ions into stable aragonite microcrystals, which remain suspended in the flow and are flushed out naturally, rather than forming scale on heating elements and pipework.
An integrated stainless steel filter (50 μm) captures suspended particles, while a high-performance neodymium magnet traps ferromagnetic impurities, delivering dual protection for potable systems. Gary Perry, Managing Director at Altecnic, commented: “With the UK’s push toward low-carbon heating and greater system efficiency, the Caleffi eCAL® arrives at the perfect time. Installers and specifiers need reliable, sustainable ways to protect modern heating systems without introducing chemicals or costly maintenance. eCAL® delivers all that in a compact, plug-and-play format.”

INSTANTOR
Direct Drive Press Tool
With press fittings being increasingly used across the sector there has also been a growth in the number of press tools available, which continued this year. The new press tool from Instantor does not feature a hydraulic mechanism, instead a direct drive brushless motor powers the tool. The company says the new tool is, “a major leap forward in tool technology.”
The tool features automatic press operation – there is no need to hold the button; users can press for 1–2 seconds and release. A press completion light has also been added, flashing green when a press is successful and red when incomplete.
Other features include a digital OLED screen that advises users of press counts and the battery life, while indicating any faults that may arise. There is also an integrated work light for dark installations, while the swivel head helps with awkward angles.
The new tool is compatible with the current offering of Instantor jaws and battery packs and promises improved balance and ergonomics. For added peace of mind, Instantor is offering a three-year warranty.

MAKITA MAKTRAK TOOL STORAGE SYSTEM
Tool storage is important to installers and to help keep tools secure and organised Makita has introduced a new MAKTRAK™ system, designed to provide a tough, secure and flexible modular storage method for a wide range of the company’s tools and equipment. A key feature of the new system is its horizontal stacking design – meaning any box can be opened without unstacking. Plus a dual-hinge system is included, designed for easy access –boxes can be opened from either side or lid removed completely.
The Rolling Tool Chest forms the base of the MAKTRAK™ system. The company says its horizontal layout can accommodate even long tools and combined with the dual-hinged removable lid, it ensures full and easy access from both sides – useful for tight spaces or when accessing the chest from the back of a van. There are seven different components to choose from comprising of four toolboxes – the Large Toolbox, Extra-large Extension Toolbox, both of which include the dual hinged lid feature, a Medium Toolbox, as well as the Rolling Tool Chest, and three organiser boxes the Deep Medium Organiser, Low Profile Organiser and Deep Compact Organiser.

TALON FlueSnug FS5
Back in 2017, PHPI reported on the launch of PipeSnug. Since then, the brand has gone from strength to strength and when Talon took on the product range it promised new products – and the company delivered this year, in the form of the FlueSnug 5” (FS5).
The FS5 has been engineered to fit into an existing 5" flue opening, to create a secure, professional seal without the need for additional making good. It also supports compliance with Part L of the Building Regulations, helping to minimise thermal bridging and maintain a building’s energy performance.
Dean Heathfield, Commercial Director at Talon said: “The FS5 is precisely sized to fit the existing flue opening, making flue replacements faster, neater and fully compliant with the latest building regulations. Installers can simply slot the FS5 into place and quickly secure the new flue without the need for mortar, sealant or patching, speeding up installations and reducing disruption for both the installer and the homeowner.”

Biting winds, frozen pipes, slippery ground: winter brings its own challenges on site. Carhartt outlines some of the workwear that can help professionals keep working safely and comfortably, whatever the weather.
When the first frost hits, everyone in the trade feels it. Cold hands, stiff joints, damp clothes; the winter weather can make even routine jobs harder, slower and riskier. If you’re someone whose job involves time outside, stocking up with the right workwear for the weather is essential.
It’s easy to think just layering up with old T-Shirts or thick hoodies will do the job. And of course it will to an extent. But there’s plenty of carefully designed, practical workwear out there that can really improve your working day.
It’s worth taking a good look at what’s around and picking up the layers that will keep you warm without weighing you down, dry quickly without trapping sweat and protect you without losing movement.
Here are five key items from Carhartt that can help make the difference when the weather changes and the temperature drops.
At the base
Winter gear works best when layered properly and a breathable base layer will help manage sweat and temperature changes throughout the day. The right material does more than just feel comfortable; there are fabrics that will actively draw moisture away from the skin and prevent the cold, damp feeling that can set in when moving between warmer indoor spaces and outdoor work.
Carhartt’s Force™ range uses sweat-wicking technology to boost airflow and keep skin dry. It is a technology that has been designed for anyone working hard: it is stretchy, dries fast and prevents odours. Our new Force™ T-Shirts have mesh panels for air circulation and an improved seam so there’s no uncomfortable distractions. The Carhartt Force™ Relaxed Long Sleeve T-Shirt is
LAYER UP
lightweight and airy, dries fast and has plenty of stretch. It also has reflective taping for added visibility on darker days. But the Force™ range is wide and also includes hoodies, sweatshirts, trousers, socks – all doing the same job of keeping you cool, dry and comfortable.
there’s plenty of carefully designed,
practical workwear out there that can really improve your working day
Stay flexible
It can be hard to move from relaxed shorts into thick winter trousers. They can feel restrictive, tight and uncomfortable after the freedom of summer. There are some benefits to moving into trousers of course: reinforced knees, abrasion-resistant fabrics and designs that accommodate kneepads all help when working on frozen concrete, uneven ground or in confined spaces. But comfort is key too and while the right pair of trousers will resist tears and offer protection where it’s needed most, they should also be flexible and move with you when you’re squatting or crawling or reaching.
Carhartt’s Steel Pants are well-suited for winter. The Ripstop Double-Front Dungarees for example, use a
grid-patterned ripstop weave that prevents small tears from spreading, always an advantage on sites with rough surfaces and sharp edges. They incorporate Rugged Flex™ technology too, so stretch is built into the fabric. The articulated knees allow for crouching and bending even in cold weather when fabrics can stiffen, and Cordura® reinforcements protect high-wear areas like pockets and knees from fraying or splitting.
Weatherproof warmth
A good jacket is the foundation of any winter wardrobe. It should trap heat, block wind and repel moisture but also allow you to move without restriction. Carhartt’s Active Jacs have been around for 50 years now and are a great choice for outside work. The whole range has been designed for maximum warmth with rib-knit cuffs and waistbands to seal out drafts and a large hood to fit over hard hats or beanies.
The Washed Duck Bartlett Active Jac incorporates Full Swing™, a design that was developed with the Carhartt Crew (a group of working testers) to give maximum natural movement. It has bigger bends in the elbows and increased stretch across the shoulders and back to help free movement. If you need something a bit lighter and water resistant, the Gilliam Active Jac has Rain Defender™ technology so rain beads up and rolls off.
On your feet
Winter brings two major challenges underfoot: moisture and instability. Slippery ladders, muddy sites and freezing ground all test footwear performance. Boots for the season should combine waterproofing, insulation and grip without adding excess weight.
Waterproof membranes such as Storm Defender™ keep water out but allow heat and vapour to escape, preventing clamminess and overheating. Vibram soles provide dependable traction on wet or uneven surfaces, while scuff-resistant
leather extends the lifespan of the boot in tough conditions. The Carter S3 Pull On Safety Boot has all these features together with a padded collar and fully cushioned footbed for extra comfort. The boot has heel and ankle reinforcements and a nylon shank which add extra support when working outdoors.
Finishing touches
Smaller items are often the easiest to overlook but can make the biggest difference; on cold mornings or late dark evenings you need to keep your extremities warm. Up to 10% of body heat can be lost through the head so a
well-fitted beanie or hat is essential. The Carhartt Knit Cuffed Beanie, made from soft rib-knit acrylic, provides a secure fit and reliable warmth and fits comfortably under a hard hat or hood.
At the other end, socks can make or break the day. Carhartt’s Force™ crew socks are thick and warm with a heel pocket. The Force™ technology also fights sweat and smells so keep your feet dry and at a comfortable temperature throughout the day.
Winter workwear needs to be both safe and comfortable when the conditions are against you. Cold reduces muscle performance and wet clothing saps energy so choosing gear that fits properly, resists the elements and allows movement helps protect against both fatigue and distraction.
From weatherproof jackets to flexible trousers, supportive boots and moisture-managing layers, each item has a role in keeping you working safely and effectively through the colder months.

ON THE MOVE
Keeping tools secure, tidy and easy to transport can help make jobs run more smoothly. PHPI runs through a couple of solutions from KNIPEX.
Transporting tools and equipment can be a headache at times, but professional solutions can help keep tools secure and to hand, right when they are needed. Two solutions from Knipex, its Modular X18 Tool Backpack (00 21 50 S) and the Robust26 Move Tool Case (00 21 33 S) have been designed to provide tradespeople with practical, dependable transport solutions for everyday kit.
The Modular X18 Backpack features front and back panels that open fully for easy access while there is also a
removable tool board designed to keep everything in order. A padded back helps make it comfortable to carry.
The bag’s 18-litre capacity is divided into compartments for tools, measuring instruments and even a tablet or notebook. The company says the impact-resistant waterproof base keeps it upright and clean and the outer fabric, made from recycled fibres, is splash-proof and easy to maintain.
well stocked
Both storage systems can come stocked with 17 brand tools, including 12 from KNIPEX. The selection includes...
● The KNIPEX TwinKey® Control Cabinet Key (00 11 01) – 10 profiles in one for standard cabinets and shut-off systems
● Two KNIPEX Cobra® Water Pump Pliers (180mm and 300mm)
● KNIPEX BiX® Pipe Cutter
● The KNIPEX Tubix® 90 31 02 BK for precise cutting of copper, brass and stainless steel pipes
The bag features magnetic and mechanical FIDLOCK® connectors designed to lock fast but open instantly when needed and also heavy duty MOLLE webbing designed to keep tools tight and secure, with one strap inside and four outside for attaching clips or accessories. There are 21 loops and 37 pockets, providing storage for a wide variety of tools and equipment.
On the case
For those who prefer to wheel their gear, the Robust26 Move has an extendable handle and smooth-running wheels designed to make it easy to transport. Padlock eyelets provide security on site or in transit, while a built-in document compartment keeps paperwork dry and organised.
This 26.4-litre case has 80 insertion options (19 pockets and 61 loops) plus a lockable base tray that can be divided using aluminium separators.
It is made from impact-resistant polypropylene and the company says that it is dustproof, watertight and able to handle temperatures from -30°C to +80°C.

WATCH ZILMET INTAFIL EXPANSION VESSEL
For more videos check out the PHPI YouTube channel
www.rdr.link/ pbv036
In this video on the PHPI YouTube channel Chirag from CP Utility Solutions installs a Zilmet Intafil Expansion Vessel whilst running through some of the benefits of the slim-line solution.
In this video Chirag is changing a standard expansion vessel for a new slim-line option. During the installation he takes a look through the features of the Zilmet Vessel, highlighting its slim-line design and points out that it comes with a number of additional parts in the box. Chirag says: “So you’ve got the expansion vessel itself. It also comes with a new filling loop kit, you’ve got your pressure relief valve, you’ve got your pressure gauge, and in this box we also have our multifunction valve. And there is no reason to source separate parts.”
Full installation
Explaining that it is straightforward to fit Chirag notes: “The slim-line vessels, you’d have to actually try to fit it badly. They are so easy to fit, it is literally two or three screws and it mounts straight onto the wall.”
In the video Chirag then explains how to fit the new filling loop and the non-return valve. He notes: “It is, of course, WRAS approved, so that meets the UK Water Regs and it’s got a 360 degree rotatable safety relief valve so it means that you don’t have to worry about which way your discharge is facing. You can get
this mounted however you want. You’ve also got the double check valve on the isolation valve on the cold main so that prevents the back flow as well.”
Summing up towards the end of the installation Chirag notes: “It is highly durable and it’s built for reliability and longevity.”
Once the installation is complete, Chirag runs through how to top up the system pressure.

RF SOLUTIONS MAINSLINK
In this video on the PHPI YouTube channel Chirag from CP Utility Solutions demonstrates how to use a Mainslink by RF Solutions to fix a heating system pump overrun wirelessly.
At a recent job in Hertfordshire, Chirag tackled the installation of a Mainslink from RF Solutions to provide a pump overrun in a situation where the boiler is in a garage and the pump is in an upstairs airing cupboard. Running a cable right through the house would cause disruption and could be a complex and costly job.
Chirag notes: “...it’s not really feasible for us to run a cable from that pump to the boiler for it to be able to do its pump overrun. So, the best solution, the cost-effective solution and the time-saving solution is to use the RF Solutions Mainslink.”
Running through the components of the solution, Chirag says: “You’ve got two units in here, one unit we are going to fit here by the boiler. The other unit is going to go upstairs where the pump is.” Chirag continues that the installation will, “send a wireless mains switch from that pump to the boiler, and vice versa, so that the boiler can actually talk to the pump wirelessly without us having to run any cables.”
In the box
Chrirag explores what comes in the box, which includes two units, the receiver (RX) and transmitter (TX), along with the glands needed for installation. He reinforces that it is important to fit these the correct way round saying: “Your transmitter is going to go here by the boiler... receiver upstairs where the pump is.”
The unit is IP68 rated and made in the UK. Chirag notes: “I’ve fitted multiples of these and I have never had any call-backs.”
Commenting on the strength of the wireless signal Chirag explains: “This has actually got the LoRa technology built in, so it has a stronger range and it will actually work up to 5km away, which we are not going to have that problem here from downstairs to upstairs, but it just gives you that reassurance that if you are working in a large property and it has got to try and get through multiple different floors or levels or walls, with the LoRa technology you can rest assured you are not going to lose signal.”
Chirag concludes: "If you have got to run a cable or if you need to get a permanent live supply from point A to point B, and it is not a straightforward run, why would you use anything else. This is an all-in-one solution for you.”
