Ground source heat pumps are recognised as vitally important in helping the UK achieve its net carbon zero target, with the government aiming for 600,000 of them to be installed a year by 2028 – a significant increase in current market volumes. Every ground source heat pump installed is the equivalent of taking a combustion engine car off the road. To date over 1 million tonnes of carbon will be saved as a result of Kensa’s ground source heat pump installations across social housing, new build developments, private retrofit homes, and businesses in the UK. “Kensa has passionately advocated for a long time that ground source heat pumps are best placed to deliver low carbon heat to the UK. There is a particularly welcome focus from Government in ensuring a large proportion are manufactured here to boost our green economy,” said Kensa Group CEO, Simon Lomax. “In response, we are committed to scaling up production to meet increased demand and fulfil the Government’s ambition to ‘build back greener’. Our mission is to connect thousands more people in homes and businesses across the country to cleaner, greener, affordable heat.” “Our teams have been working hard to deliver fantastic outcomes over the last few months. In the midst of the challenges of a stretched global supply chain, a labour shortage, and significantly increased volumes, Kensa celebrated the highest monthly turnover ever and continues to break records in UK heat pump production,” he added. Kensa has been manufacturing award-winning ground source heat pumps from the heart of Cornwall since 1999 and pioneering the adoption of this environmentally-friendly technology for over two decades. With a product range designed for UK properties and specialist installation division working on large-scale multiple occupancy projects, market share has grown steadily over the years to 50%, bolstered by the Group’s partnership with Legal & General in 2020. To match this rapid growth, the manufacturer has added well over 60 jobs in the past year and is continually recruiting. To facilitate the widespread roll-out of the technology, Kensa is urging Government to focus efforts on street-by-street installations of networked heat pumps, rather than replacing gas boilers on a house-by-house basis. This would enable whole communities to simply switch to their gas boilers to highly efficient ground source heat pumps when they are ready to transition, supported by a subsidy from the government. If entities such as utility companies and local authorities took ownership of this underground infrastructure, then consumers would simply pay a standing charge as they do in their gas bills for the supply to their boiler.
Leading industrial engineering firm, Clade, has opened its newly expanded Technology Centre in Morley, Leeds, boosting production of heat pumps and creating over 300 new jobs in the area. Andrea Jenkyns, MP for Morley, formally opened the factory in a ceremony on 11 February 2022. For over 30 years, Clade has been leading energy transformation in heating and cooling using cutting-edge natural refrigerants. In order to furthersupport the UK’s transition to a greener economy, the new 29,000 sq foot factory will be dedicated to the production of Clade’s range of industry-leading CO2 heat pumps. Demand for Clade’s range of natural refrigerant heat pumps has grown across, commercial and industrial sectors. The expansion will enable Clade to significantly increase production by 400%. In addition, the company is creating over 300 new jobs over the next four years, split between factory floor and office roles. As a sustainable company, Clade ensures that its production processes are as green as possible. This includes the installation of solar PV to help generate clean energy, fitting electric vehicle charging points, using LED lighting and implementing waste reduction strategies. Alongside this, the company maintains its operation-wide policy for offsetting carbon generation through tree planting, with over 1000 trees planted, removing CO2 from the atmosphere and creating space for wildlife. On the factory opening, Dean Frost, Managing Director at Clade, said: “Opening this new technology centre is an important step for us to take. The last few years have been challenging for everyone, so it is fantastic to be able to share this celebration of success with our valued stakeholders, staff, customers and suppliers who have been with us on this journey, and will be for many years to come. “We are committed to tackling the challenges of climate change and our new facility will enable us to increase production, develop innovative new products and support the local community through job creation and subsequent impact on the supply chain” Dean added. Tim Rook, Chief Markets Officer at Clade, said the new facility will enable the company to accelerate the adoption of green heating technologies:“As the importance of tackling the climate emergency has become more urgent, Clade have developed high-performance heat pumps which will decarbonise heat in buildings and industrial processes throughout the UK and beyond. Heat makes up 40% of the UKs carbon footprint and heat pumps are the only viable solution, readily available and able to be deployed at scale quickly enough to make a difference.” “We are passionate about making our products work in the real world, supporting customers to get the very best long-term value from them and are looking forward to being able to expand our production, enabling more people to benefit from the carbon savings heat pumps create,” Tim concluded.

The Ground Source Heat Pump Association, which represents heat pump system designers, contractors and installers across the UK, welcomes the BEIS Select Committee’s report on Heat Decarbonisation (to be published on 3 February). Laura Bishop, chair of the GSHPA, said: “The Select Committee acknowledges the central importance of heat pumps to decarbonise heating in homes across the UK; without heat pumps, the UK’s Net Zero ambitions will be hard to achieve. As the Committee points out, the pace of change now needs to pick up and firm policy measures put in place, if the Government’s ambition to see 600,000 heat pumps installed every year by 2028 is to be realised.” “Undoubtedly, it’s a complex and challenging task but it can be met through specific policy instruments and through greater collaboration with Government – central, devolved, regional and local, the heating industry, Trades Unions and importantly the customer.” “Households across the country need greater assurance about the cost and environmental benefits of heat pumps, and the practicalities of switching from a gas boiler to a low-carbon heat pump. Heat pumps are suitable for the majority of homes in the UK.” “The GSHPA is pleased that the Select Committee has highlighted a number of measures to ramp up the heat pump roll-out, not least the need for a consumer finance scheme, selected grants for consumers and industry, improved training/upskilling of the labour market and a Heat Decarbonisation Sector Deal. These are all measures that the GSHPA has called for, as well as the lifting of the environmental levies on electricity for those using heat pumps. These environmental levies are inhibiting the adoption of heat pumps and encouraging the continued burning of gas for heating and are undermining the UK’s heat decarbonisation policies.” “The GSHPA will continue to work closely with Government and all interested parties to deliver the country’s Net Zero ambitions, and the specific ambition to have low-carbon domestic heating in all parts of the UK.”
Heat pumps have been very much in the news recently. Interest in them began to increase when it was announced that from 2025 gas boilers could no longer be installed in new homes. Then more recently gas prices soared, and the government announced that there would be grants available for homeowners to purchase heat pumps. So, what is the deal with heat pumps? Heat pumps are by no means new. I was first introduced to heat pumps 30 years ago while visiting a community of sustainable housing. As a carbon reduction engineer, I have been recommending heat pumps for a very long time. This is because they can offer a low carbon solution to providing warmth, and with appropriate consideration can offer a versatile solution. Many places have already fitted heat pumps – they can be found in homes and on libraries, they are heating schools and even the most forward thinking of factory buildings. Yet to many there is still mystery surrounding them. There can be a misconception that heat pumps can only be fitted where there is enough land space to dig down into and fit a ground source heat pump, or to new builds. But there are three main types of heat pump – air to air, water source and geothermal or ground heat pumps, giving a range of application. Air source heat pumps are suitable for a wider range of buildings. They can be fitted to any building, either new build or existing. Air pump ones, for example, are suitable even for older buildings with no garden and examples of these can be found on Victorian terraces in London. Air pumps can have disadvantages though. One concern is noise, especially given the domestic setting, as the pump is fitted on the outside of the house, and so near neighbouring homes. Imagine one fitted in your street. Then imagine every house in the row having one. And if they are not well maintained they are noisier. In addition, homes they are fitted to will need more insulation, and ideally under floor heating. Heat pumps are also more expensive – relative to a new gas boiler they cost about £4,000 more. This disadvantage might be addressed by the recently announced government grants offering £5,000 to buy a heat pump. But the funding available will not meet the full cost of buying and installing a heat pump. It is likely that homeowners will need to find around £2,500 to install a funded heat pump. The funding pot will amount to around 90,000 grants – so the remaining hundreds of thousands of homes will not be able to benefit. As non-domestic heating incentives closed a while back the funding would be for homes only, not businesses, though there is the possibility it could be used for owners’ accommodation, or a home that is yet to be converted into a BnB. Even so, with rising costs for gas, and a need for solutions to carbon emission, and so the climate crisis, they may work out cheaper than the alternative of leaving global warming unchecked.

Daikin Altherma 3 R is the world’s first high-capacity R-32 refrigerant split heat pump that offers cooling, along with heating and domestic hot water. The third generation R-32 refrigerant heat pump is even more sustainable and replaces the previous generations that run on R410-A refrigerant. This change represents a reduction of 75% in the environmental impact. Daikin Altherma 3 R stands out thanks to its improved compactness, design and performance. Innovation as a driving force to net zero heating and cooling As the market leader, Daikin Europe is constantly looking for innovation possibilities for heat pumps. Daikin Altherma 3 R is setting new standards: it’s the world’s first high-capacity R-32 refrigerant split air-to-water heat pump that also offers cooling. Similar heat pumps already exist in a heating and domestic hot water set-up, but Daikin went a step further and added the cooling feature. Importantly, Daikin Altherma 3 R runs on R-32 refrigerant. It replaces its predecessors that run on the R410-A refrigerant. R-32 has a global warming potential (GWP) that is one-third lower than R410-A. Deciding to use an R-32 product reduces the environmental impact by 75% compared to R-410A. It leads directly to lower energy consumption, thanks to its high energy efficiency. Patrick Crombez, General Manager Heating and Renewables SBU at Daikin Europe, specifies, “At Daikin, innovation, along with sustainability, is a driving force in everything we do. Daikin Altherma 3 R combines both factors in a rather unique way: It’s not only a world’s first, but also a sustainable promise.“ Improved compactness, design and performance Daikin Altherma 3 R is the perfect heat pump for new large houses thanks to its improved compactness, design and performance. Its outside unit is smaller and can fit under a window: it is equipped with 1 large fan instead of 2 smaller ones for a high-capacity unit, reducing its height by 25%. This unobtrusive heat pump seems to blend into any environment since it hides the fan from view via a black front grille made of horizontal lines. It offers all-year round comfort with heating, domestic hot water and cooling, a world premiere for a high-capacity R-32 refrigerant split heat pump. This heat pump has it all: it is a versatile air-to-water heat pump for new large buildings. Daikin Altherma 3 R ERLA-D series product specifications • Available in 3 classes: 11, 14, 16 kW, 1 and 3 phase • Dimensions (HxWxD): 870 x 1100 x 460 mm • Patented plate heat exchanger • Up to A+++ space heating performance • Up to A+ domestic hot water performance • Operation range down to -25°C • 60°C LWT at -7°C • Combinable with 3 different indoor units (wall mounted, floor standing with integrated tank, floor standing with ECH2O tank) • Cloud ready
Green Street in Glasgow, just a stone’s throw from COP26 will show that the only way to install 600,000 heat pumps a year and hit net zero is by replacing the UK’s current gas grid. The inner city street will be brought to life using pioneering augmented reality to show how networked ground source heat pumps that mimic the current gas network are the cheapest way to decarbonise heat and could save the UK an estimated £1bn a year to 2050. The solution shifts responsibility from consumers getting rid of their gas boilers and installing individual infrastructure for ground source heat pumps on an ad-hoc house-by-house basis, to the pre-installation of utility-scale underground infrastructure that allows consumers to easily and cheaply change to ground source heat pumps when they’re ready. The infrastructure is funded, owned and maintained by an energy or water company, local authority or private investor removing the cost from consumers who pay a standing charge similar to gas. Simon Lomax, CEO of Kensa, the UK’s only manufacturer of ground source heat pumps, said: “It isn’t possible to reach critical mass or secure the cost reductions expected by government by adopting a house-by-house approach, placing responsibility to deliver our climate targets on individuals. “To really kick-start the transition to heat pumps, the government needs to work with the energy industry and suppliers to popularise a networked ground source heat pump where the cost of infrastructure is divorced from the heat pump in a split-ownership approach. “Running costs and carbon emissions will be far lower than any other heating choice. Pre-installation of the infrastructure means whole communities such as tower blocks can switch to individual networked heat pumps simultaneously, as well as enabling households to easily and affordably make the transition from their gas boiler to a heat pump when they’re ready to change, with minimal disruption.” Kensa’s ‘Welcome to Green Street’ launching on 1 November at COP26, created by Emmy award winners Alchemy Immersive, will prove how a whole systems approach to decarbonising how we heat our homes can unlock benefits across communities and compliment and balance the electric network as we come to reply more heavily on it with heating and electric vehicles. Simon added: “Green Street is our way of setting out a virtual street map that proves any street can be a Green Street, by showing how the ground beneath our feet can transform how we heat and power our homes and accelerate progress on climate change through the lowest carbon, cost and electrical grid compact solution. “By utilising waste heat and low-temperature ambient loop systems our solution connects homes and businesses to deliver sustainable heating and cooling that’s highly efficient, low carbon and low cost for all stakeholders and enables the balance of energy supply and demand.” Kensa has been engaging with energy suppliers, the UK and Scottish governments and other leading organisations and continues to make progress to making the ‘Green Street’ solution a national reality. Thousands of properties across the UK are already enjoying the benefits of networked heat pumps. Thenue Housing which has homes in Green Street, said it welcomed innovative and trailblazing solutions to the global climate emergency including those which relate to domestic energy consumption. Eleanor Derbyshire, Head of Property Services at Thenue Housing, said: “Thenue Housing is delighted that one of the streets where we have our housing stock should be showcased in this way as the way forward in terms of energy consumption and conservation. We recently invested in our on-site heating so while we are currently not planning to make energy-related changes to our homes in Green Street, we think there is no better-named street anywhere in the city to highlight this work. “As a housing provider which has strong historical links with Glasgow and its heritage, we readily acknowledge the need for action at this game-changing summit where so much can be gained by global co-operation on climate change.” Since 1999 Cornwall’s Kensa has saved over 1 million tonnes of carbon through ground source heat pump installations across social housing, new build and retrofit homes and businesses. It was the first company to prove a solution for flats and apartments through its small ‘Shoebox’ heat pump, used by many city councils and recognised by the Greater London Authority as the most efficient, lowest carbon, lowest cost solution for heating and cooling high-rise buildings.

The newly unveiled Heat and Buildings strategy doesn’t go far enough to address major problems in the race to reach Net Zero, warns Tim Rook, Chief Markets Officer at Clade Engineering, a leading designer and manufacturer of CO2 heat pumps. The long-awaited strategy was unveiled yesterday and contains details of the Government’s £3,9bn plan to improve access to energy efficient heating technologies. Part of this is a £450m boiler upgrade scheme, which will allow homeowners to apply for grants of £5,000 towards installation of low-carbon heating systems, such as heat pumps. However, when delving into the details, Tim is concerned that the plan doesn’t go far enough. “It’s great to see the Government finally moving on the climate critical issue of heat and promoting heat pumps as the best form of sustainable heating technology on the market. However, the strategy is far too small and fails to adequately address the major issue of the difference between the price of gas and that of power. If the Government were to rebalance this it would transform the market and really drive mass adoption of low carbon heat pumps,” Tim explains. “The strategy is further confused by the inclusion of hydrogen and weakened by many follow-on consultations and studies. There is some content that is likely political bluster, such as the mention of 25% price reductions for green technologies and its disappointing to see house buildings being given at least three more years of building inefficient housing when we could be building better right now.” He adds Decarbonising heat is one of the most effective ways of lowering emissions in the UK, but with 85% of UK homes reliant on gas for heating, more needs to be done to improve access to green heating technologies. £5,000 grants will help just 90,000 households, a drop in the ocean against the 600,000 annual installations needed by 2028 to reach Net Zero. Time is of the essence, as Tim explains,“There is a fixed budget of carbon we can release into the atmosphere before we exceed our target of 1.5C of global warming. If we fritter that budget away in a short period of time, we don’t get it back. Leaders have to stop being wilfully blind, recognise the critical risks we face and act fast to mitigate them, for all our sakes.
“Although the Government’s Heat and Buildings Strategy does look like a clear indication of ongoing investment, it doesn’t go far enough. “When considering a heat pump there are many factors to assess which are not considered here, such as the property’s suitability. A home may need to be adapted to accommodate a heat pump, such as resizing radiators and making space for hot water cylinders, which carry cost implications. Therefore, the proposed grants may help with the cost to purchase a heat pump, but there will still be costly investment required from homeowners in existing properties. “As for boilers, the strategy does not refer to any legislation behind a boiler ban, so it’s not surprising that there is confusion among installers and homeowners. “Whilst it is encouraging to see that hydrogen is still on the agenda and is referred to within the Strategy, it is a shame to see that a decision around hydrogen won’t be made until five years from now. With hydrogen-ready boilers already successfully trialled, they could be a strong alternative to fossil fuel boilers on the market today – yet this strategy seems to omit them. “We are committed to the decarbonisation of heating and hot water in the UK and will continue to work with Government and industry to offer a technology agnostic future, while educating and inspiring homeowners to make greener choices for home heating.”
British Gas has become the latest organisation to sign up to the UK’s main F-Gas register REFCOM as it seeks to keep pace with growing demand for heat pump installations. The energy giant’s social housing subsidiary PH Jones maintains more than 195,000 homes across the UK. It supports 23 social housing providers, has carried out almost half a million service calls and installs more than 11,000 heating systems and 850 renewable projects annually. A growing number of these installations now involve renewable systems with noticeable growth in heat pumps. It is actively recruiting to increase its team of skilled engineers and grow installation work backed up by ongoing expert service and maintenance. With the social housing sector moving more quickly towards low and zero carbon targets than other parts of the residential market, British Gas said upskilling the PH Jones workforce was a priority. “The industry is clearly suffering from an acute skills shortage, and it is crucial that large employers like us step up to address it,” said PH Jones director Matt Isherwood. “As well as bringing new engineers into the sector, we also need to upskill our existing workforce, particularly those already involved in boiler installations and other ‘traditional’ heating projects. “They will be crucial to delivering high performing heat pump systems in line with the government’s ambitions, but the technology does require specialist skills. We recognise the importance of making sure everyone working for us is properly trained, accredited, and able to comply with legislation. Credentials “That is why we were very keen to become REFCOM members as it is the best way to demonstrate our credentials and support higher standards across the sector,” he added. The government has set the industry the challenge of installing 600,000 heat pumps a year by 2028 – an almost ten-fold increase on current rates – and the Climate Change Committee believes 19 million will have to be installed to meet the country’s net zero carbon emissions target by 2050. PH Jones already has 11 F-gas qualified engineers and a larger team specialising in its renewables work. The agreement it has signed with REFCOM will allow it to eventually register many more certified operatives in line with its plans to expand its workforce. Founded in 1963, it now employs around 600 staff. Its social housing and facilities management business was acquired by British Gas in 2011. It received a ROSPA gold medal in 2019 following five successive years of receiving the prestigious health & safety initiative’s gold award. REFCOM is celebrating 25 years of helping refrigeration and air conditioning companies demonstrate their business and technical credentials and promoting higher professional standards of refrigerant management. Originally set up as a voluntary scheme in 1996 by a group of contractors who wanted to demonstrate their commitment to high professional standards and responsible refrigerant handling, it became the mandatory register for compliance with the European F-Gas regulation in 2009. It recently recorded its 7,000th company membership, which represents an estimated 90% of the total number of firms operating in the refrigeration and air conditioning sectors. The UK continues to ‘mirror’ the F-Gas Regulation despite its departure from the EU, which means that all personnel carrying out installation, commissioning, decommissioning, repairing, maintenance, or servicing of stationary refrigeration, air-conditioning or heat pump equipment that contains or is designed to contain F-Gas refrigerants must hold the relevant designated qualifications.www.phjones.co.uk/www.refcom.org.uk
The Building Engineering Services Association (BESA) has secured extra government funding to provide a further 200 free places on its online heat pump training course. BESA developed the installer training in collaboration with the Home Builders Federation (HBF) and heating equipment manufacturer Worcester Bosch. Launched in March, it has already trained for free more than 700 qualified plumbing and heating engineers, who were looking to upskill to take on heat pump work. The course is delivered through the Association’s online training Academy and this new round of funding, which comes from unspent Green Homes Grant scheme money, will allow it to extend the free programme until the end of October. New applicants should sign up here and are urged to move quickly as demand continues to be high as the market for heat pumps expands encouraging more companies and individuals to diversify into this area. Heat pumps were highlighted by the Prime Minister as a key technology for delivering many of the government’s decarbonisation goals and he tasked the industry with installing 600,000 a year by 2028. The Committee on Climate Change (CCC) also set a target of one million a year by the 2030’s towards an eventual total of 19 million to help achieve net zero by 2050. Industry estimates for this year put the current number of heat pump installations at around 71,000 and ramping that up to achieve the government’s ultimate target would require an additional 40,000 trained installers, according to the Heat Pump Association. Challenge The BESA Academy training scheme is a direct response to that challenge, according to the Association’s director of training and skills Helen Yeulet. “One of the biggest barriers to increased adoption of heat pump technology is the lack of suitably qualified installers,” she said. “It is also very important that installations meet a high technical standard and that engineers fully understand the technology, so consumers get the full energy and carbon saving benefits. “We are delighted to be working in collaboration with the HBF and Worcester Bosch because our combined expertise means we can include the most up-to-date knowledge in the training and use people who really understand the subject to deliver it.” Alongside the training course, BESA has updated its guide to good practice for heat pump installation (TR/30). This is the only guide that clearly identifies and explains all the different types of heat pump available and clarifies the type of training needed for successful installation. It also explains how to avoid many of the design problems that have impaired the performance of some systems to improve consumer satisfaction and cut more carbon emissions. The guide, which is available to buy from the BESA website, draws on the increased experience of heat pump technology in the field and provides an overview of the different applications including their benefits and limitations as well as providing outline design information for each. It contains updated references to building standards and codes of practice as well as data referenced from the latest CIBSE and BSRIA guides. Carbon emission factors have been updated along with explanations of new and emerging technologies that use different refrigerant types and blends which bring new hazards and safety considerations. “Since the first edition of this guide was published, there has been a significant increase in the use of heat pump technologies, which has resulted in a broader range of choices for end users, specifiers and installers, and also a greater knowledge of their potential benefits and pitfalls,” said Will Pitt, chair of the BESA technical committee. “New regulations, assurance schemes, government incentives and market entrants mean that heat pumps are now a far bigger presence in our industry. This makes the need for a recognised source of good practice increasingly vital to avoid some of the design problems that can undermine performance and disappoint end users.” TR30 is available to buy here. It costs £70 to BESA members and £140 to non-members. To sign up for heat pump training go to: www.thebesa.com/hpi
