Warm homes
The Government’s Warm Homes Plan was announced to the public in late January. The £15billion programme of public investment could help five million homes upgrade with energy efficiency technologies through a mixture of loans and grants. There are three areas of the scheme: for low-income households, renters, and all households across the UK. Technologies mentioned as part of the scheme include Solar PV, Batteries and Heat Pumps.
In the UK, the Heat Pump sector is currently far smaller than the established heating technology – boilers – but it is growing. Thanks to the Boiler Upgrade Scheme (BUS) households can access a £7,500 grant for heat pump installations, and the Warm Homes Plan announcement should provide further confidence to the sector.
Charlotte Lee, Chief Executive of the Heat Pump Association UK reacted to the announcement of the Warm Homes Plan saying: “The plan acknowledges the vital role of heat pumps as a proven, scalable solution that can lower energy bills, improve comfort, and reduce carbon emissions for homes and buildings across the UK.”
Paul Smith, Managing Director, of heat pump manufacturer NIBE Energy Systems Limited said: “The Warm Homes Plan provides much-needed clarity and long-term direction for the acceleration of heat pumps in UK homes, backed by record public investment. It sends a strong signal that clean heating is central to the future of housing in Britain.” You can find more reactions to the Warm Homes Plan announcement on page 12
As heat pumps become more widely seen and understood, it is likely that demand for the technology will further increase. It is likely that additional finance options, including those outlined in the Warm Homes Plan, together with existing grants will further unlock the market.
Installers armed with the training and skills required to install and maintain heat pumps are well placed to engage with this growing sector and deliver low-carbon heating to customers. For those interested in finding out more, there are now many training opportunities available across the sector, together with growing levels of support from manufacturers.
Boilers, of course, remain an established heating technology, familiar and understood by both installers and customers alike. In this issue we find out a little more about Worcester Bosch’s recently introduced Floor standing boiler (please turn to page 26) and we delve into Heat-only boilers (please turn to page 18).
Heating engineers are at the forefront of ensuring homes remain warm and comfortable places to live – whichever technology is used.

WORK STARTS ON LAWTON TUBES NEW HQ
Lawton Tubes, a supplier and manufacturer of 100 per cent recyclable copper tube and fittings, is set to more than double its capacity, after work on its new state-of-the-art headquarters in Coventry officially got underway.
The company is gearing up to open a new £20 million facility next year to meet growing domestic demand for its plumbing and heating and air conditioning products. The company says the new facility will equal the size of approximately 40 tennis courts – double the size of its existing headquarters that will also remain operational. It will include a 107,768 sq ft warehouse along with 17,220 sq ft of office space and welfare areas and a 40-metre service yard.
The milestone comes 107 years after the business was initially co-founded in Coventry by Albert Lawton, whose family still operate the business today.
INSTALLERS’ ROLE IN
CONTROLLING COSTS REVEALED
The latest energy attitudes research from Resideo – the manufacturer of the Honeywell Home heating control range –has found that concerns over energy costs do not appear to be subsiding. The poll showed 74% of homeowners expressing concerns over 2025/2026 winter energy costs compared to 70% for the previous winter.
Nearly half (48%) of the respondents said they still rely upon a professional installer for guidance on what thermostats to purchase and install, with two thirds (67%) wanting professional installation. The result indicate the important role HVAC installers can have in guiding future heating decision-making.
“We are a pioneer of using innovative technology to help increase comfort levels in the home and we believe that there is a great opportunity for installers to help more households to better tackle their energy cost concerns through connected thermostats,” said Steve Warrington, Country Sales Director, UK at Resideo. "Our focus is to create a more sustainable future by delivering products and solutions that meet installers and consumer needs of increased heating control and lower energy bills.”
19% OF VAN OWNERS PREFER UNBRANDED VEHICLES
According to a recent survey by temporary business van insurance, Tempcover –who surveyed 500 van owners across the UK – almost a one-in-five of van owners (19%) prefer to keep their vans unbranded with (31%) saying they avoid branding to prevent attracting unwanted attention. Security and cost also play a part: 18% worry about theft, and 22% cite higher repair costs if the van is damaged or vandalised.
However, for many van owners branding is a key marketing tool, with nearly half (47%) fully branding their vehicles with logos, contact details, or signage. A further quarter (25%) opt for partial branding, such as smaller decals or stickers.
Claire Wills-McKissick, temporary business van insurance expert at Tempcover, said: “A van is often the backbone of a business, so it’s vital to keep it secure. While eye-catching designs can help attract new customers, they can also draw unwanted attention. Simple steps, such as parking in well-lit areas, using additional security locks, and avoiding leaving tools inside overnight, can go a long way in reducing risk. Temporary business van insurance can also offer valuable peace of mind, whether you’re using a spare van, covering short-term jobs, or need flexible protection while your regular policy is under review. It’s a smart way to stay protected without committing to a full-term policy.”
GRANT UK CONTINUES SUPPORT FOR WILTSHIRE AND BATH AIR AMBULANCE
Grant UK has continued its long-standing support for Wiltshire and Bath Air Ambulance, with its 2025 fundraising activities culminating in the company donating £10,000 to the charity.
Since 2019, Grant UK has supported Wiltshire and Bath Air Ambulance who provide specialist critical care by land and air to patients in extreme and life-threatening situations.
Fundraising activities
In 2025, the Grant UK Team organised and took part in fundraising activities which included popular bake sales, a competitive Easter Egg Hunt, a STEPtember step count challenge and the annual Christmas raffle. As a result, the company was able to donate a further £10,000 to Wiltshire and Bath Air Ambulance which brings Grant UK’s grand total of donations to the charity to £85,000.

We are also pleased to confirm that Grant UK will be supporting Wiltshire and Bath Air Ambulance as our chosen Charity Partner for 2026.”
TWO-THIRDS OF TRADESPEOPLE LEFT CHASING LATE PAYMENTS
Late payments are becoming an increasing problem for UK tradespeople, according to new research by Direct Line business insurance, with over half (53%) saying they are experiencing more late payments than a year ago.
Direct Line says the scale of the problem is stark, with tradespeople owed an average of £2,023 in late payments. Over two-thirds (68%) of tradespeople are currently chasing at least one late payment from their clients. Many are juggling multiple outstanding debts: almost one in four (23%) are currently chasing four or more late payments simultaneously, with 7% chasing six or more.
Payment delays
Nearly half (46%) of tradespeople say that they now ask customers for ‘proof of funds’ before starting larger jobs with a further four in 10 (44%) saying that they are considering doing so. The most common proactive measure is taking half the payment upfront (39%), followed by sending invoices well in advance (29%) and charging late payment fees (26%).
Mark Summerville, Product Manager at Direct Line business insurance commented: “Late payments are often cited by tradespeople as their biggest problem. When a client fails to pay on time after work is completed, it can create a highly stressful situation. Payment delays disrupt both personal and business finances, affecting the ability to cover bills and manage cash flow for future projects. In some cases, tradespeople feel they have no choice but to write off unpaid invoices, which is not only financially damaging but also deeply demoralising.”

NUMBER OF APPLICATIONS TO BOILER UPGRADE SCHEME DIPS IN FINAL MONTH OF 2025
The latest data on the Boiler Upgrade Scheme shows that the number of applications in December was lower than November’s figures.
Reacting to the news Gav Murray, Home Heating Director at Hive, said: “Despite a slight dip in December’s data, 2025 has been a strong year for the Boiler Upgrade Scheme, with more homeowners than ever switching to more sustainable heating.
"The government’s long-awaited Warm Homes Plan is a clear signal of intent to support the widespread adoption of heat pumps and ensure all households have access to greener homes. Making the technology more accessible and affordable through low and zero interest loans, removing noise restriction barriers and cutting installation times are all positive signals that the government is rising to the challenge to deliver on its green agenda.”
WARM HOMES PLAN–REACTIONS
The heating sector reacts to the launch of the Warm Homes Plan, designed to upgrade homes and reduce energy bills.
Towards the end of January, the Government published its much-anticipated Warm Homes Plan outlining its approach to tackling fuel poverty, upgrading homes and helping keep energy bills down. The £15billion Warm Homes Plan includes measures on solar panels, heat pumps and batteries designed to help low-income families and make clean energy technologies more accessible for all.
Here is a snapshot of reactions from across the sector.
HENRIK HANSEN
Managing Director, Vaillant UK and Ireland
“Vaillant welcomes the £15 billion Warm Homes Plan as an important step forward, providing long term certainty for the market and a clear signal on the UK’s transition to low‑carbon heating.
“The ambition for 70% of heat pumps sold in the UK to be manufactured domestically, alongside continued support through the Boiler Upgrade Scheme and further investment in installer skills via the Heat Training Grant, gives industry the confidence to plan, invest and scale with purpose. This rounded approach, including investment in the broader supply chain, from manufacturing to installation, not only strengthens the domestic manufacturing base but also fosters a robust ecosystem for skilled jobs and growth.”
PAUL SMITH
Managing Director, NIBE Energy Systems Limited
“The Warm Homes Plan provides much-needed clarity and long-term direction for the acceleration of heat
pumps in UK homes, backed by record public investment. It sends a strong signal that clean heating is central to the future of housing in Britain.
“The continued expansion of the Boiler Upgrade Scheme (BUS), alongside new zero- and low-interest finance, is an important step in making the upfront cost of installation less prohibitive and opening clean heating to many more households. Increased funding will also support the adoption of a broader range of heat pump technologies, helping ensure different homes can access the right solutions.”
HAMID SALIMI
Head of Residential Products, Daikin
“The Warm Homes Plan will accelerate progress towards net zero. It will make it cheaper to install and run low carbon heating, making heat pumps even more attractive, particularly when they are paired with solar PV and battery technologies.
The ability to apply for a low or zero interest loan on-top of the Boiler Upgrade Scheme (BUS) grant is particularly welcome, as it will encourage more

householders to invest in this technology. As hotter climate conditions become an increasing issue in the UK, we welcome BUS funding being extended to air-to-air heat pumps that can cool as well as heat homes.
“We would, however, urge the government to take early and decisive steps to reduce the price of electricity. This remains a barrier to the electrification of domestic, commercial and industrial heating.”
MIKE FOSTER
Chief Executive, EUA
“New, highly insulated homes provide the ideal environment for modern low carbon technologies such as heat pumps and heat networks. As the government advances its ambitious housebuilding programme, we expect to see significant growth in heat pump installations in new build properties.
“Our experience of more than a decade of subsidising heat pumps in existing homes shows that uptake is likely to remain limited until installation becomes more affordable and running costs decrease.
Hamid Salimi, Head of Residential Products, Daikin
“Where we see real potential for lowering energy bills and cutting carbon emissions is in hybrid heating technologies. Aligning solutions with the realities of the UK’s diverse housing stock is the most pragmatic path forward. Hybrid systems also support the transition to a future decarbonised gas network, helping the UK meet its clean power goals in a way that remains affordable for households.”
CHARLOTTE LEE
Chief Executive, Heat Pump Association UK
“Today’s publication, and the £15 billion confirmed to deliver the Warm Homes Plan, send a strong signal to both industry and consumers that the shift to clean, affordable, electrified heat remains a priority for this Government. The plan acknowledges the vital role of heat pumps as a proven, scalable solution that can lower energy bills, improve comfort, and reduce carbon emissions for homes and buildings across the UK."
NEIL SAWERS
Commercial Technical Manager, Grant UK
“The launch of the Warm Homes Plan is potentially a key moment for energy affordability across Britain and underlines this Government’s commitment to cleaner energy. The Plan’s three-pillar approach is welcome; direct support for low-income families, an offer of universal access to clean energy financing and meaningful protections for renters. Heat pumps are

central to the new Warm Homes Plan and we are pleased about the continued focus on this proven and clean home heating solution.”
RUSSELL DEAN
Deputy Divisional Manager, Mitsubishi Electric
“We are pleased to see the Warm Homes Plan outlined today, as this level of support to make renewable heating options more affordable and accessible has been long called for. The plan to offer interest-free loans for heat pumps is a welcome step to further reduce upfront costs, and the continuation of the Boiler Upgrade Scheme shows that the government is serious about making heat pumps a realistic option for more of us.”
SACHIN VIHBUTE
HVAC and Heat Pumps Technical Consultant and Product Training Manager, LG
“The Warm Homes Plan puts serious weight behind clean heat, with a £2.7bn commitment to the Boiler Upgrade Scheme that could be a real turning point for heat pump adoption.
“But while the plan sets out funding and ambition, it is lighter on the practical measures needed to help heat pump installations scale at pace. Financial support is an important part of the picture, but clearer consumer guidance and long-term policy certainty will be essential to give households and installers the confidence to invest.
“Manufacturers are already playing their part in supporting this transition –investing in innovation and helping to build a skilled workforce ready to meet growing demand."
Kevin Wellman, CEO of the Chartered Institute of Plumbing and Heating Engineering (CIPHE) provides some thoughts on the recently announced Warm Homes Plan.
“The Warm Homes Plan is a welcome and necessary step towards tackling fuel poverty, improving energy efficiency, and cutting carbon from the UK’s homes. Moving to more efficient heating systems is central to delivering warmer homes at lower running costs. However, this ambition must be matched with capability as the recognised skills shortage is now fast becoming a skills crisis. To make this transition work at scale, we need a highly trained workforce with the right skills and confidence to design, install, and maintain low carbon heating systems.
“We are already supporting this shift through targeted training and guidance, including our new publication on Low Temperature Hydronic Heating Systems. Investment in skills is not optional; it is essential if the Warm Homes Plan is to succeed. This plan provides a vital opportunity to embed high-quality, efficient heating and hot water systems from the outset, ensuring homes are fit for a low-carbon future and that skilled professionals are ready to deliver it.
“By prioritising training, standards and clear guidance, government and the plumbing and heating industry can work together to ensure households genuinely feel the benefits of lower bills, improved comfort and reduced emissions, while creating long-term, skilled jobs across the sector.”

PANASONIC’S NEW Heat Pump facty
The Czech Republic has long been a popular tourist destination, with visitors heading to the nation’s capital, Prague, to view the beautiful Old Town, walk over the historic Charles bridge and see the medieval astronomical clock.
But with Panasonic recently opening a new Heat Pump factory just over an hour's drive away, in Pilsen, PHPI recently visited to check out the new plant.
The initial impression of Panasonic’s Heat Pump production facility in Pilsen is its scale. Although a Panasonic facility has been in the city since 1997 the company has recently spent €320m to repurpose and significantly enlarge it, creating a dedicated Heat Pump production plant with a production area of 140,000m2
The capacity for Heat Pump production in Europe has recently been given a significant boost with Panasonic opening a new plant with a production area of 140,000m2. PHPI recently visited the facility in Pilsen, Czech Republic, to discover more.
The building itself features multiple floors including production, training rooms and a new Research & Development centre. It is also one of the company’s Net Zero factories – the facility is run using a combination of green energy purchases
and its own 1 MW photovoltaic power production on the roof of the factory.
European supply
The company says the new production complex will be capable of producing up to 1.4 million outdoor and indoor heat pump units (combined) per year from 2030 onwards for residential and commercial applications, for supply throughout Europe.
"At Panasonic, we see Europe as particularly advanced when it comes to sustainability, and therefore the acceptance of sustainable energy solutions. We’re seeing a marked uptick in interest in heat pumps in the European market, and we are anticipating this to be reflected in demand in the next few years. Our investment into the Pilsen factory demonstrates both our confidence in the growth of the market and our ability to anticipate and meet future demand," said Toshikatsu Fukunaga, CEO, Panasonic HVAC Europe.
Research & development
Alongside the production of Heat Pumps, Panasonic has, in cooperation with a local university, also created a new center at the Pilsen plant focused on future heat pump developments. As a key partner in the establishment of the R&D facility, the Technical University of Ostrava has designed and is due to build one of the research laboratories. By 2028, the company says, the Pilsen R&D team will manage the full heat pump development lifecycle, in coordination with the product planning division in Japan.
“The factory in Pilsen is set to become Panasonic’s central hub for heat pump production and supply in Europe. By placing further R&D capabilities and production together on the same site, we’ll be able to ensure that the factory is able to rapidly and nimbly anticipate and respond
to the evolving needs of this key market. There will also be cost savings associated with reduced logistics, in addition to the speed and flexibility associated with bringing R&D and production together,” explained Radek Vach, Business Planning Director, Panasonic HVAC CZ.
Autonomous vehicles
The factory currently has 80 robots deployed on site, and the layout has been optimised for the future deployment of automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) for material supply and finished product transport. In future, the company says, the facility plans to achieve 100% automation in component manufacturing.
It also has a smart building management (BMS) system to intelligently control ventilation, heating and lighting (including
“As a company with a strong European presence, Panasonic is committed to advancing clean heating and cooling solutions and supporting policies that enable the widespread adoption of heat pumps. A stable regulatory environment and ambitious climate targets are essential for accelerating the green energy transition and ensuring robust business cases for clean technologies. This is vital not only for the planet, but also to ensure robust business cases for clean technologies.”
Enrique Vilamitjana, Managing Director of Panasonic Heating & Cooling Solutions Europe
sensor-controlled LED lighting throughout the facility), and it reuses waste heat from ventilators and compressors to heat the building and help reduce energy consumption. Water waste is minimised via a retention reservoir which catches and reuses rain water.
In addition, the company says that starting in 2026, the facility’s vehicle fleet will move to Electric Vehicles (EVs) to further reduce the carbon footprint.
Central location
The central location of the Czech Republic was a reason the site was selected for the Heat Pump facility.
Tetsumasa Mizuta, Managing Director, Panasonic HVAC CZ, said: "The Czech Republic is geographically located in the heart of Europe, with accessibility within 24 hours to all European destinations. As the first Japanese company to enter the Czech Republic, Panasonic began operations in Pilsen in 1997. A pioneer of investments in the country, Panasonic has strong relationships and networks –including government and supply chain –in the Czech Republic, which we plan to leverage as we grow our team in Pilsen,”
Radek Vach, Business Planning Director, Panasonic HVAC CZ, added: “Pilsen itself is in the Czech Republic‘s own ‘Silicon Valley,’ with many high growth and innovative tech companies nearby, making it the perfect location to leverage and support local talent and foster connections.”

HEAT-ONLY BOILERS // 4 SCENARIOS
Heat-only boilers may have found themselves overtaken by their combi counterparts in the popularity stakes, but the solution remains a strong one for installers in a variety of situations. Here, Andy Speake, portfolio manager at Baxi, details four sets of circumstances that lend themselves to a heat-only boiler installation.
1
Keeping the hot water cylinder for the long term
Heat-only boilers are versatile in nature. They are suitable for both sealed and open vent systems and are ideal for customers not yet ready to replace their feed and expansion tanks. The expansion vessel and pump are separately located in the property, meaning the boiler can be cost-effectively replaced without having to change other expensive pieces of equipment.
The systems allow homeowners to keep their hot water cylinders, making it easier for them to embark on future home upgrades, including the addition of an air source heat pump (ASHP) as space is effectively reserved for the ASHP cylinder. This is also a win for installers, who can benefit from quicker jobs without the need
The benefit of being able to directly swap one boiler for another with greater performance potential can be a significant one
to carry out a complete refit on a heating system. This faster turnaround can make installers available for more business opportunities while creating less disruption for homeowners.
2
The straightforward swap
The benefit of being able to directly swap one boiler for another with greater performance potential can be a significant one for heating-savvy homeowners dealing with rising energy bills.
Working with heat-only boilers is also much more straightforward for installers. Because expansion vessels and pumps are typically located in the airing cupboard, these jobs involve simpler wiring thanks to no pump overrun or permanent live being required. This also eliminates the need to run wires from the boiler to the pump.
819
Market-leading heat-only boilers such as Baxi’s have been designed with installers in mind. They are lightweight, compact (for airing or kitchen cupboard spaces), use flexible flueing (top or in-case rear flue) and incorporate positive fix hanging brackets for an easy and reassuring fit.
enhances comfort, especially for households with remote workers or young children. Quiet operation can be a key selling point during consultations as many customers will have previously relied on an outdated, louder boiler.
Heat-only boilers are versatile in nature. They are suitable for both sealed and open vent systems and are ideal for customers not yet ready to replace their feed and expansion tanks.
Uncompromised outputs
The best products are those developed with both installers and end users in mind. When these solutions are shaped by user needs and wants, they perform better and make a real difference to heating systems.
The Baxi 430, for example, is designed to meet installer demand for more complete heat-only solutions giving a high output and coming with an option for a 5-year warranty.

FAQs ANTI-FREEZEVALVES & HEAT PUMPPROTECTION
Steve Elsmore – Senior Technical Support, Altecnic – provides some advice on using anti-freeze valves to provide protection for Heat Pumps.
Heat pumps are built to run efficiently all year round, but winter weather can introduce an important challenge of having to protect the system from frost. When temperatures drop, water sitting in exposed flow and return pipework can begin to freeze.
This FAQ article explains why frost protection is essential for heat pump installations, what areas are most vulnerable, and how anti-freeze valves help protect external pipework during low temperatures, supporting system reliability and performance.
QWhat parts of a heat pump system are most at risk of freezing?
The area’s most at risk are usually the parts that are exposed to outdoor temperatures, especially external pipework connected to an air source heat pump. Flow and return lines installed outside the property cool faster than internal pipework and are more likely to freeze during cold weather.
This risk can increase further if external pipework is exposed to wind chill, installed in shaded areas, or if the system isn’t circulating water regularly. When water freezes inside a pipe, it expands and can place the pipework and fittings under
significant strain. Even if the pipe doesn’t split immediately, freezing can weaken joints and seals. Once temperatures rise and the ice thaws, this can result in leaks, pressure loss, or system faults.
A frozen pipe can also restrict or fully block flow. When flow is disrupted, many heat pumps will detect the issue and shut down for safety. That means no heating output at the time it’s needed most, and a greater chance of emergency callouts during the winter period.
The valve must remain free of insulation so it can sense temperature correctly and operate as designed
Q What is an Anti-Freeze Valve used for?
An anti-freeze valve helps prevent ice forming in a heat pump circuit, protecting the system from freezing conditions. It reduces the risk of damage to equipment, valves, and external pipework, which can occur if water in the system freezes.
Q How does an Anti-Freeze Valve work?
Anti-freeze valves are fitted on the external flow and return pipework connected to the heat pump. Their operation is based on temperature.
● When the temperature drops below 3°C, the valve opens automatically and allows system water to drip and discharge safely, helping prevent freezing.
● When the temperature rises above 4°C, the valve closes again, preventing unnecessary draining.
This controlled discharge helps remove water from the vulnerable outdoor sections of the circuit before it can freeze. Once conditions improve, the valve shuts again to preserve system water and allow the heat pump to continue operating normally.
Q Where should an Anti-Freeze Valve be installed?
Anti-freeze valves should be installed on the external pipework of the heat pump system. It is recommended to install them on both:
● Flow pipe
● Return pipe
Fitting anti-freeze valves on both lines helps ensure the external circuit can drain properly when required. If only one valve is installed, water may remain in the other side of the pipework and still be at risk of freezing. That trapped water can create the very conditions frost protection is meant to prevent, particularly during extended low temperatures.
Q What orientation should an Anti-Freeze Valve be installed in?
Correct orientation is essential for proper performance. Anti-freeze valves must be installed:
● Vertically only
● With the outlet facing downwards
This positioning ensures water drains freely out of the valve. If installed incorrectly, water may not discharge properly, which could reduce frost protection performance and increase the risk of trapped water and freezing.
As part of good installation practice, it’s also important that discharged water can flow away without obstruction. The valve needs a clear path to drain, particularly when temperatures are close to freezing and any slow flow may begin to ice up.
Q Does the system need to stay pressurised for the valve to work properly?
Yes. For correct performance, the system should be kept under pressure at all times, including during discharge. Pressure helps maintain consistent system behaviour and
supports the valve’s intended operation. Maintaining system pressure is also important for overall heat pump performance. A drop in pressure can cause faults, disrupt flow, and may affect how the heat pump responds during cold weather.
Q Can I install an Anti-Freeze Valve where the pipework creates a ‘trap’?
No, trap connections must be avoided. If external pipework is shaped in a way that creates a ‘trap effect,’ part of the circuit may not drain fully when the valve opens. This can leave water sitting in low points of pipework. In freezing conditions, that remaining water may still freeze, meaning frost protection is no longer guaranteed. To maintain effective protection, external pipe runs should be designed with drainage in mind. Pipework should allow water to drain freely, without dips or loops that prevent the circuit from emptying.
Q How far from the floor must the Anti-Freeze Valve be installed?
For the iStop® Anti-Freeze Valve, leave at least:
● 15 cm clearance from the ground
This clearance is important because a block of ice may form below the outlet during discharge. If the valve is installed too close to the ground, ice buildup can block drainage, preventing water from flowing out properly and reducing frost protection effectiveness.
Q How far apart should two Anti-Freeze Valves be installed?
For the iStop® Anti-Freeze Valve, keep a minimum distance of:
● 10 cm between valves
For the iStop® PLUS (where the sensor is off axis), the pair of valves can be installed vertically in parallel, allowing a more compact installation layout and greater flexibility depending on available space and preferred pipe routing.
Correct spacing helps ensure both valves operate effectively and supports good access for maintenance or inspection.
QShould Anti-Freeze Valves be insulated?
No. The valve must remain free of insulation so it can sense temperature correctly and operate as designed.
While insulating external pipework is often good practice to reduce heat loss and improve efficiency, insulating the valve itself may prevent it from detecting low temperatures accurately. If the valve cannot sense the cold conditions, it may not open when needed, which could compromise frost protection.

DIGITALWATERMULTIMETER
Andrew Carver, Research and Design Manager at Salamander
Pumps explains why investing in a digital water multimeter makes sense for installers.
For installers to achieve both optimal system performance and customer satisfaction, accurate water measurements are essential.
With readings that are precise and reliable, installers can make sure potential issues are identified faster and systems can be specified with greater confidence.
Opting for traditional testing methods involves using multiple tools and can inevitably return inconsistent or inaccurate results. This lack of precision can mean installers have to repeat tests or leave them second-guessing the measurements, which can add unnecessary time, complexity and frustration to the job.
Salamander Pumps’ AquaScan addresses these challenges head on. Our 4-in-1 digital water multimeter is designed to quickly deliver accurate, reliable data for installers.
AquaScan provides live, easy-to-read measurements for water flow, pressure, temperature, and hardness (via Total Dissolved Solids).
These measurements are delivered in seconds, eliminating uncertainty and allowing installers to work with complete confidence. The result is greater accuracy and efficiency, improved customer satisfaction and a single solution for an installer’s measurement needs.
How AquaScan is being used by installers
For installers, AquaScan is a smart investment that supports confident, data-driven decision-making.
By providing clear and reliable measurements, potential issues can be easily identified and addressed. This can help to maintain system efficiency, extend appliance lifespan and deliver outcomes that meet customer expectations.
Our community of installers have told us that they use AquaScan for tasks including, but not limited to:
Accurate - the AquaScan 4-in-1 digital water multimeter measures flow, pressure, temperature and hardness via TDS
mains-fed systems
● Checking water pressure and identifying potential issues within mains pipework
● Monitoring water temperatures across gravity and mains-fed outlets
● Supporting commissioning and routine servicing
● Producing accurate project quotes through effective system specification
Fast, efficient measurements to helpsave time
For busy plumbers, completing work efficiently and effectively without compromising on quality or service is key to a job being profitable.
To understand how AquaScan is used in real-world settings, we spoke with members of our installer community. One respondent, who measures water flow, pressure, temperature and hardness three times a week, reported that AquaScan was nine times faster overall than traditional methods.
This time saving equates to a full 24-hour day saved each year simply by using AquaScan for routine measurements. By removing guesswork from water testing, AquaScan helps plumbers work more efficiently while delivering more accurate diagnostics and solutions. This ensures systems perform optimally from day one, reduces callbacks, and strengthens professional reputation.
Precise - a garden tap is the best location for AquaScan to measure the incoming flow
Gary, a member of our installer community, commented: “Without AquaScan, I couldn’t have tested accurately at numerous points and diagnosed the exact issue.
“The digital display is very clear to read and compared to a weir cup, is a great visual aid for customers to be able to see exactly what they do/don’t have.”
AquaScan also eliminates the need to carry and use multiple measurement tools. Even small inefficiencies, like returning to the van to collect different devices, can add significant time over the course of a job, especially when combined with the limitations of traditional testing methods.
“I’ve found traditional methods more time consuming and it was not as easy to set up a dynamic test,” said one installer Michael.
“Also, the TDS measurement is great and, again, is easier to setup without the need to get another measuring instrument from the van.”
The tool also enables installers to get to the bottom of an installation issue quickly.
I.R.B Heating told us about their use of AquaScan, which is “mainly using it for doing surveys for new boilers.”
“When I’m looking to fit a new combi, it’s good to know what flow rate they have so I can select the correct output boiler.”
More professional, more customers
Whether they are existing or new customers, how installers are perceived is hugely important.
Using digital measurement tools rather than traditional analogue methods can help improve this perception. AquaScan helps position installers as being modern, forward-thinking operators who want accurate-first-time results which, in turn, bolsters the customer’s confidence before work even begins. Daniel, a member of our installer community, said he uses
AquaScan over traditional methods as it “looks 100 times more professional and the display is easier to read and either show in person or take a quick snap to send it on.”
Installers can also show customers accurate readings directly on the device, explain what the results mean and confidently outline the recommended solution. Accurate diagnosis and specification before any installation can also be hugely influential on a customer’s perception. This can help prevent potential, costly callbacks and avoid unnecessary spend on incorrectly specified solutions, which will save both customers and installers time and money in the long run.
Using a professional, all-in-one tool reinforces trust and positions installers as reliable experts customers are happy to return to.
Why investing in AquaScan makes sense
AquaScan delivers more professional approach to water measurement, providing installers with fast, accurate results to support reliable diagnostics and specification.
The proof in why installers should invest in AquaScan lies in the feedback we’ve received with from our community.
Stephen, an installer we spoke with, said: “AquaScan makes it easier to explain findings to customers, thanks to its clear display. I would absolutely recommend it to other installers –in fact, I’d say it’s an essential piece of kit.”

TIPS HEAT PUMP INSTALLATIONS
Drawing on Navien’s field experience with the PEM750 heat pump and the company’s installer training partnership with Ultimate Renewables, Gareth Prescott, National Trainer at Navien UK, explores five areas every installer should look to master.
The heating industry is undergoing its biggest transformation in decades. With the UK Government targeting 600,000 heat pump installations annually by 2028, and regulatory changes now making them simpler to fit, demand is climbing fast.
According to figures from the Microgeneration Scheme (MCS), in 2024, nearly 60,000 heat pumps were installed across the UK – a figure set to rise steeply each year. For installers, this is both a challenge and a unique opportunity: those who master heat pumps now will place themselves at the front of tomorrow’s heating market.
But success depends on getting every stage right. Heat pumps work to much tighter tolerances than many conventional systems, so any errors in sizing, siting, or commissioning can quickly affect performance and customer satisfaction. Installed correctly, however, they can deliver efficient, low carbon comfort and help installers build long term trust and loyalty.
Pre-installation essentials
Preparation is the foundation of a successful install. A full site survey should always be the first step: assessing heat loss, electrical capacity, and insulation levels. A UK Parliament POSTnote report states that “heat pumps are technically suitable for most UK homes if installed
Positioning matters more with heat pumps than almost any other heating technology
appropriately,” but actual suitability depends heavily on insulation quality. Ensuring walls, lofts, and floors are properly upgraded unlocks both efficiency and customer satisfaction.
Correct system sizing is critical. An oversized unit raises upfront costs and wastes energy, while an undersized system leads to frustration and complaints.
Accurate heat loss calculations, combined with manufacturer guidance, ensure the
PEM750 –or any other model –is correctly specified for the property’s demand.
Don’t overlook compliance. Meeting planning requirements, building regulations, and MCS standards from the outset prevents headaches mid-project. Finally, clear communication builds confidence - explaining that heat pumps deliver steady, lower-temperature heat over longer run times helps set realistic customer expectations and reduces call-backs.
2
Outdoor and indoor unit installation
Positioning matters more with heat pumps than almost any other heating technology. For outdoor units like the PEM750, unrestricted airflow is essential: sufficient clearance on all sides must be maintained to avoid recirculation and performance drops. Because the PEM750 uses R290 (propane) refrigerant, careful siting and ventilation are particularly important to ensure safety and compliance. Condensate discharge from the external unit should also be correctly routed and protected to prevent freezing during winter conditions.
With the one metre boundary rule now scrapped and unit size allowances expanded in 2025’s regulation updates, installers have greater flexibility for sitingbut acoustics and neighbour proximity remain key considerations.
Indoors, integration demands precision. Cylinders and pipework should be carefully planned, with insulation on all exposed pipework to reduce heat loss. Spending extra time at this stage ensures smoother operation and long-term reliability.
3
Electrical and control set-up
Electrical connection is one of the most sensitive stages. Units must be wired and earthed in line with IET regulations and manufacturer instructions. Even small errors can lead to nuisance tripping or system faults.
Control set-up deserves equal attention. Sensors should be correctly positioned and calibrated for accurate readings. Programming must be kept simple and intuitive –many customer complaints stem not from the heat pump itself, but from overly complex or unclear controls. Setting straightforward schedules and demonstrating them clearly during handover significantly boosts customer satisfaction.
4
Commissioning and optimisation
Commissioning is where an installer’s professionalism truly shines. This stage verifies that the system operates safely, efficiently, and as designed. For Navien’s PEM750, commissioning includes confirming water flow rates, verifying expansion vessel pressures, and ensuring control settings are correctly configured. Optimisation at this stage –fine-tuning flow temperatures and balancing heat emitters –secures peak efficiency and comfort. Recording performance data completes the job, providing a valuable reference point for future servicing and customer reassurance.
5
Troubleshooting and customerhandover
Even with careful planning, small issues can arise. Common early problems include limited airflow, vibration noise, or wiring faults. A structured approach – checking airflow first, then electrics, then control logic – resolves these quickly and avoids unnecessary call-backs.
The customer handover is equally vital. Demonstrating system operation, controller settings, and basic maintenance gives the homeowner confidence and reduces aftercare issues.
Supplying warranty and servicing documentation not only secures compliance but strengthens your professional reputation. A comprehensive, confident handover is often the difference between a one-off job and repeat business.
Shaping the future
Heat pumps are no longer niche; they are rapidly becoming the backbone of the UK’s low carbon heating future. For installers, this is a pivotal chance to grow both skills and business. Success depends on attention to detail at every stage –surveying, siting, electrical work, commissioning, and handover.
Navien is committed to ensuring installers are supported every step of the way. Through the PEM750 heat pump, hands-on training courses with Ultimate Renewables, and accessible digital resources, Navien is equipping the trade with the expertise to deliver reliable installations, happy customers, and sustainable businesses.

ENERGY MANAGEMENT
Heating controls were once designed simply to switch boilers on and off, however today’s smart heating controls are evolving into intelligent energy management tools that deliver real benefits to homeowners. Merlin Milner, Product Owner for Water-based Systems at Drayton, unpacks the capabilities of heating controls as they continue to develop, and highlights the valuable opportunities they present for installers.
The evolution of heating controls is being driven by a growing awareness of energy consumption and desire to reduce this as much as possible. As energy bills continue to rise, homeowners are more focused on how they can manage their energy usage more effectively without having to compromise the comfort of their home environment. While smart heating controls have played an important role in this for years, their capabilities, and the value they add, are now rapidly growing.
Smarter homes
Traditionally, heating controls were engineered to maintain a set temperature at specific times of day. Although this was effective, it led to wasted energy by heating unoccupied rooms or running systems longer than needed.
The introduction of smart heating controls eliminated these issues through features such as multi-zone control, allowing homeowners to heat individual rooms rather than the whole house.
Remote access via smartphone apps also added another layer of convenience, as it allows users to adjust heating from wherever they are at any time and avoid unnecessary usage.
Many smart controls also feature smart modes, which can help to optimise heating schedules and energy consumption. For instance, Wiser’s Eco Mode learns the
thermal properties of the home using optimum stop and weather compensation. This enables the system to ensure the desired comfort level is maintained but also could turn off the heating ahead of its scheduled timings. Away Mode is another feature which overrides the schedule and switches the heating off when a property is empty, therefore reducing the amount of wasted energy.
For homeowners, these elements lead to more control, improved comfort, enhanced energy efficiency and help to lower bills. Smart solutions also remove the need for constant user input and adjustment and instead uses intelligent automations.
Smart heating controls have evolved to combine energy savings with everyday user convenience
Home management
The housing sector is continuing to adapt to the net zero ambitions of the country,and this has also changed the role of heating controls. Homes are becoming more electrified, and heating controls are developing to keep up with this shift by managing energy consumption, going beyond just regulating temperatures of a property.
Alongside advanced heating functions, they can now integrate other products, such as lighting, security alarms, motion sensors leak detection and more into a single, intuitive system. This doesn’t just offer convenience; it also plays a role in improving efficiency too. When installed, sensors can detect when a window has been left open and automatically pause
heating in that room to avoid wasting energy. Lighting controls ensure lights are only used when needed, and power micro modules can be used to heat hot water during off-peak tariff periods rather than at peak times, so that homeowners take advantage of lower energy costs.
Drayton’s Wiser 2nd Generation demonstrates this transition. Beginning as a smart heating control, the new generation has developed into a wider home automation system, enabling homeowners to manage various elements of their home through one smartphone app. Smart heating controls have evolved to combine energy savings with everyday user convenience. This responds to consumers’ desire for convenience, while
simultaneously being key to managing energy for improved efficiency and preparing homes for the future. through automatic optimisation, adapting to changing routines and conditions.
An opportunity
As homeowners are placing greater importance on energy efficiency and convenience, advanced smart controls, like Wiser, offer a valuable upselling opportunity that goes beyond basic heating installation. Installers can offer these as long-term solutions that reduce energy bills, improve comfort and convenience, and futureproof the home. The benefits can be clearly demonstrated through capabilities such as zoning, remote control, and automations, which are key talking points for installers to have with their customers.
A smarter future
As the industry continues to move towards net zero, smart heating controls will be increasingly crucial in managing heat, but also in helping homes use energy more efficiently and sustainably. As homes become more connected and electrified, the capabilities of controls will continue to expand and will be driven to becoming more like full home energy management systems (HEMS), and it is important that installers are prepared to support their customers in this journey.

Training
TIME
The Grant UK Training Academy and continuous learning helped Laura Chown-Hammond of Accredited Heating Services become a qualified heating engineer.
QCan you tell us about your career and when you became a heating engineer?
“My journey to becoming a heating engineer, which I’ve been now for about 12 months, was a long-winded one! I started at Accredited Heating in December 2023 as a Business Development Manager to help expand the business. Shortly after joining, I said to Iain Jack (Chief Heating Engineer at Accredited Heating) that I’d like to learn more about the business by spending
field. That’s when I fell in love with being on the tools and when I made the decision to have a change in career.”
QWho do you work with at Accredited Heating?
“Our Team here at Accredited Heating comprises of Iain who is our main heating engineer, James our plumber, Julia who is an oil engineer, and myself. My role is now divided, working as an oil engineer during the Winter months and supporting the office with administration during the Summer.”
What types of heating products do you specialise in?
“I predominantly work on oil boilers and related work including oil tanks with my work spanning across both domestic and commercial installations.”
Why did you choose the Grant UK Training Academy for product training and your OFTEC assessment?
“Accredited Heating have been part of Grant UK’s G1 Installer Scheme since 2019 and we are in regular contact with Steve Farrow, our local Grant UK Area Sales Manager. Iain and I were with Steve at an event in November 2024 and I got chatting with Steve about my interest in getting some hands-on training. I mentioned to Steve that I can get quite anxious, but he reassured me that Grant UK’s Training Academy run small course sizes and the Trainers would put me at ease. And he was completely right.
“In Summer 2025, I attended the Pressure Jet Burner and Vortex Combi courses at the Grant UK Training Academy in Swindon, Wiltshire. When booking onto these courses, I mentioned my concerns to the Training Administration Team and they
I thoroughly enjoyed my two days of training and this positive experience gave me the confidence to continue my pathway to become a qualified engineer
were very supportive and reassured me. The Trainer for my oil boiler product training was Gavin and he really put me at ease – I thoroughly enjoyed my two days of training and this positive experience gave me the confidence to continue my pathway to become a qualified engineer.
“When it came to booking my OFTEC course, I could have gone to a local training centre closer to home but because the Grant UK Training Team had made me feel so comfortable, I was happy to travel so in November 2025, I completed my OFTEC training with Grant UK.”
QWhat courses have you completed?
“Alongside the two boiler courses I did last Summer, I also did my OFTEC training, completing the OFT10-600A/OFT10-105E/OFT10-101 and assessment (Oil Appliance Installation, Oil Storage and Supply Installation, and Pressure Jet Servicing and Commissioning). I also did the 1-day Aerona 290 ASHP Installer Course which I was able to attend more locally in Norwich at one of Grant UK’s partner training centres.”

QUALITY & TESTING
Maintaining the correct inhibitor concentration is important for reliable and efficient central heating systems. Here, Richard Crisp, Head of Chemistry at Fernox, offers a reminder of the role inhibitor plays, and goes on to explore the water quality testing options available, that can help to carry out this valuable task.
Installers are well aware that when untreated water comes into contact with metal components, corrosion occurs, leading to sludge, limescale and the build-up of other system debris over time. Inevitably, this reduces system efficiency, increases the risk of boiler breakdown, and forces the system to work harder than it should have to.
None of this is good news for the homeowner, who quite literally pays the price with higher energy consumption and increased energy bills. More carbon emissions also means bad news from an environmental standpoint. However, all of this is thankfully avoidable - if central heating systems are properly protected and maintained.
This is why the British Standard code of practice for the preparation, maintenance and commissioning of domestic heating
systems (BS 7593:2019), states that using a high-quality corrosion inhibitor, also known as a protector, in a central heating system is essential. It plays a fundamental role in keeping systems energy efficient because adding an inhibitor will help to prevent the formation of corrosion and limescale in the first place, as the system’s metal surfaces will be chemically protected.
When it comes to making sure central heating systems are protected, on site system testing is a sure-fire way of making sure inhibitors levels are correct
This is a fact further supported by The Benchmark Commissioning Checklist, which asks installers to go the next step and also verify the type and brand of both cleaning and inhibitor products used during the commissioning stage.
This is also underpinned in Part L of the Building Regulations in England, which incorporates measures to reduce CO2 emissions and keep central heating systems working efficiently. Therefore, every heating system installation, repair and service carried out in a domestic environment must be carried out in accordance with BS 7593:2019.
Annual on-site testing
It is crucial to ensure that the correct levels of inhibitor are maintained throughout the life of a system, to reduce the risk of breakdowns and optimise its efficiency.
BS 7593:2019 also requires regular testing of the system water. A best practice approach means that both on site annual testing and full system laboratory testing every five years should be conducted. If a system is fully protected, it will have inhibitor levels of 100ppm or above. The Fernox Express Inhibitor Test is a great example of a go-to option that offers a quick result about the level of inhibitor in a central heating system. By simply dipping the test strip into the system water, installers can ascertain if re-dosing is needed just by referring to the colour displayed on the dipped strip and comparing it to the colour chart on the bottle.
The Fernox Express Inhibitor Test can also be used in conjunction with the Fernox App, which saves the results and produces a lab-style report certificate.
Laboratory testing
A heating system must either be re-dosed at five-year intervals or undergo a full laboratory analysis during the same period, with redosing as required. Kits are available to help installers collect water samples for accurate laboratory testing.
The Fernox Express Inhibitor Test is a great example of a go-to option that offers a quick result about the level of inhibitor in a central heating system
There are also laboratory tests that can be accessed via smart phones. Leading manufacturers such as Fernox provide a paperless postal laboratory service to provide a system diagnostic check of five, key water quality criteria including appearance, pH, conductivity, protector concentration and cleaner residue.
Results allow installers to ensure that the correct levels of inhibitor are present and to check if there is any cleaner residue in the system if it has been powerflushed, as this could increase the rate of corrosion in a system if it isn’t properly removed.
By taking advantage of a more comprehensive testing method such as this, installers can also receive recommendations from a specialist team, about the most effective means of treating the system to restore efficiency and extend its service life.
Testing, testing…
When it comes to making sure central heating systems are protected, on site system testing is a sure-fire way of making sure inhibitors levels are correct. Then given the ease of which far more detailed systems analysis can be accessed, it is worthwhile looking at the options available if you haven’t before, particularly when faced with a problematic system or a customer who would like detailed insight when provided with a quote.
By undertaking system testing, installers are using all powers at their disposal to keep systems efficient and effective and to comply with best practice requirements and industry codes of practice.

WATCH GRUNDFOS GO RANGE
www.rdr.link/ pbx019
At a house in Essex, Chirag from CP Utility Solutions changes an integral pump, using the Grundfos Go App to identify the replacement and set-up the new pump.
In this new video, Chriag from CP Utility Solutions is changing an integral pump at a house in Essex. He uses the Grundfos GO app to determine the correct replacement pump before fitting a new Grundfos UPS4 GO pump at the property.
Chirag then uses the GO app to ensure the new pump is running at the correct load. He notes: “Then the app. It couldn’t be simpler. Scan the pump, follow the prompts on the app. It’s super simple, step-by-step guide, replicates it straight onto the new pump and you are away.”
Having
these two pumps on the van,
it just makes it
easier for me.
It
makes it more cost effective for the customer and I’m in and out on the first visit.
Van stock
Explaining why he always keeps both the Grundfos UPS4 GO and ALPHA2 GO pumps on his van, Chirag notes: “Having these two pumps on the van, it just makes it easier for me. It makes it more cost effective for the customer and I’m in and out on the first visit.”
Considering how the job went, Chirag notes: “A couple of things that I found really easy about this job is, firstly, I only have to replace the pump head. I haven't got to replace the whole housing or the body or anything, which means disturbing less connections, less potential problems to go wrong. It's one off, one on, and you're done.”
By keeping the two different Grundfos GO pumps in the van installers can cut down on visiting the property multiple times, as Chirag explains: “So, this is why I keep these two pumps on the van and the FCI cable, because 70% of the time I'm going to be able to walk into a customer's house, do a first time fix, get the job done, get paid, get out, get on to the next job. It's literally as easy as that.”

GRUNDFOS GO APP AND GO RANGE
Pump solutions supplier, Grundfos, has reported that its newly optimised Grundfos GO app, working alongside its new GO circulator range, is redefining the way installers approach boiler pump replacements. The combination, it says, provides installers with a faster, smarter, and more reliable way to diagnose, replace, and commission heating systems.
Traditionally, replacing an integrated circulator could mean checking compatibility and carrying multiple spare pumps. Grundfos says the GO range solves this by reducing van stock to just two pumps and an adapter — covering the majority of boiler integrated and standalone domestic circulator replacements.
Paired with the GO app, installers can identify the correct replacement rapidly by scanning the old pump nameplate, use guided commissioning workflows to select the correct control mode and setpoint, optimise bypass valves and system parameters using app supported recommendations and reduce errors and callbacks with real time warnings, status information, and system insights.
The app processes trend data, event logs, and historical performance metrics such as flow, head, temperature, and on cycle time — providing diagnostic insight designed to speed up fault finding and improve accuracy. Within the GO App there is also a product catalogue, online sizing and replacement tools, documentation and reporting, troubleshooting, alarms, training content and guided setup for the ALPHA GO range.
