Electrification of Heat project – properties of all types suitable for heat pump installation

There is no property type or architectural era that is unsuitable for a heat pump – the Government-funded Electrification of Heat project has demonstrated.

From Victorian mid-terraces to pre-WWII semis and a 1960s block of flats – the project has proven that heat pumps can be successfully installed in homes from every style and era.

The Electrification of Heat (EoH) demonstration project, funded by the Department for Business, Energy and Industrial Strategy (BEIS), is seeking to better understand the technical and practical feasibility of a large-scale rollout of heat pumps into existing British homes.

Energy Systems Catapult was appointed to lead the Management Contractor consortium and today releases the first EoH report on Heat Pump Installation Statistics, including the numbers and types of heat pumps installed, property type/age and on vs off-gas grid.

The project appointed three Delivery Contractors to install up to 750 heat pumps in three regions across Great Britain:

South East of Scotland – lead delivery contractor Warmworks working with Energy Savings Trust and Changeworks.
Newcastle – lead delivery contractor E.ON working with Newcastle City Council and Your Homes Newcastle.
South East of England – lead delivery contractor Ovo Energy working with Kaluza, RetrofitWorks, Parity Projects and SunAmp.
The recruitment and installation phase of the EoH project ran from July 2020 through to October 2021, and despite the challenges of the Covid-19 pandemic, 742 heat pumps were installed into a broad spectrum of housing types and socio-economic groups, that reflects a representative sample of households across Great Britain.

The range of different heat pump installed, included:

Low-temperature and high-temperature air-source heat pumps
Ground-source heat pumps
Hybrid heat pumps incorporated with a gas boiler
some additional technologies, such as heat batteries were incorporated.
Energy and Clean Growth Minister, Lord Callanan, said: “Heat pumps powered by clean, renewable energy will be key to warming UK homes in a net zero future.

“This trial demonstrates that low-carbon heating systems are an effective alternative for homes of all types and ages. As technology continues to improve and costs plummet over the next decade, they will become the obvious, affordable choice for consumers.”

Richard Halsey, Capabilities Director at Energy Systems Catapult, said: “the decarbonisation of heat is vitally important to meeting Net Zero targets and electrification will play a crucial role.

“The Electrification of Heat project is helping us understand the customer journey, installation and performance of heat pumps across Britain and the role that different heat pump technologies will play in different types of homes and places.

“There is opportunity for innovation to ensure heat pumps can deliver great heating experiences and operate efficiently as part of a smarter energy system.

“Now the installation phase is complete we will be monitoring how the systems perform and the experience of households to inform the next steps on getting homes heat pump ready.”
