LOW CARBON HEATING/HVAC
HEAT NETWORKS:
POWERING SUSTAINABLE RETIREMENT LIVING
pump units that provide space and water heating to each home. Initially, Cruden Homes was concerned about the upfront cost of installing
A
low-carbon ground source heat network has been installed at The Avenue in Barnton,
a development of 48 luxury homes designed for retirement living. For its development, Cruden Homes has
received a NextGeneration Project Gold award in recognition of the scheme’s outstanding environmental credentials, with the low-carbon heat network playing a key role in helping to exceed mandatory sustainability standards. To meet project requirements, Energetics, part of the Last Mile group, installed a ground source heat network that will result in 80% lower carbon emissions than traditional gas-fired heating, and 54% lower emissions than air-source technology. The highly efficient heat network takes its heat from an array of 18 vertical boreholes. A network of pipes, manifolds and valves then distribute that ambient heat from the boreholes to heat
a heat network. However, Energetics supported the development by providing a finance model to fund the capital cost of the heat network build. Cruden Homes benefitted from a 60% capital cost saving, while residents enjoy low running costs and a fixed-rate tariff. Last Mile will own, operate and maintain the heat network. Kirsty Henderson, head of design and sustainability, Cruden Homes, said: “As developers are increasingly searching for alternatives to gas for home heating, the award- winning Barnton development showcases the economic and sustainability benefits of ground source heat networks.” Lisa Gunn, associate director of sales, Energetics, added: “We look forward to working with Cruden Homes on future developments.”

affordable heating for these properties. Mr Esterson heard how, through its partnership with utility provider GTC, Kensa is prepared to support housebuilders and bring the best possible heating to new developments.
He and Kensa CEO Tamsin Lishman also discussed the urgent need to decarbonise existing housing stock and lower household bills, hearing how Kensa is helping lift thousands of social housing tenants out of fuel poverty and replacing outdated electric or gas systems with highly efficient, compact ground source heat pumps.
Kensa also outlined its growth plans, including how it will scale up to manufacture 50,000 ground source heat pumps annually by the end of the decade. This is expected to reduce production and installation costs by at least 20%, support over 7,000 skilled green jobs across the UK, and make low-carbon heating more affordable for households nationwide. Central to Kensa’s growth is the continued rollout of the networked heat pump model. Already deployed across thousands of properties, from homes in Stithians to Edwardian-era flats and new build developments, the system mirrors the familiarity and convenience of the gas grid while delivering zero emissions at the point of use.
Bill Esterson MP, Chair of Parliament’s Energy Security and Net Zero Committee, visited the Truro headquarters of leading British ground source heat pump manufacturer Kensa to see how the Cornwall-based company is powering the UK’s shift to low-cost, low-carbon heating and helping grow the green economy.
The Chair of the Committee was given a behind-the-scenes tour of the factory, witnessing first- hand how Kensa’s innovative Shoebox and international award-winning Shoebox NX heat pumps are manufactured.
Mr Esterson also visited the nearby village of Stithians, home to Kensa’s world-first ‘Heat the Streets’project, to see how an entire neighbourhood has had its heating transformed. Launched in 2022, the scheme saw over 40 homes fitted with ground source heat pumps and connected to a shared network of boreholes and underground pipework, providing each property with clean, affordable heating.
With the long-awaited Future Homes Standard expected this year, phasing out gas boilers for new homes, discussions during the visit focused on the role of heat pumps in delivering clean,

Bill Esterson MP, Chair of the Energy Security and Net Zero Committee, said: “As Chair of the Energy Security and Net Zero Committee, I get to visit companies across the country making a massive difference to people’s lives, and Kensa is a great example of what the transition to a low carbon economy has to offer. I was very impressed by everything I saw at Kensa’s Truro factory. From the dedication to British supply chains, the creation of well-paid green jobs, which is really important to Cornwall and really important across the country, to the commitment to tackling fuel poverty and heat decarbonisation at scale. “Kensa’s networked heat pumps are a tried and tested technology that has been installed in thousands of homes across the country and has a crucial role to play in decarbonising Britain’s homes from terraced streets to high-rise blocks of flats. I look forward to continuing to work with Kensa to identify evidence of the benefits of networked heat pumps and the Future Homes Standard, so that policies are implemented as soon as possible which allow more people to benefit from affordable low carbon heat.”
