Electrification of Heat - Case studies on Heat Pump installation experiences

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, while three delivery contractors lead by Warmworks in South East of Scotland, E.On in Newcastle and Ovo Energy in South East of England.

The Challenge

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.

Householders were asked to reflect on their first hand experiences of taking part in the programme, including disruption during the installation work, thoughts on the noise and aesthetics of the technology and the outcomes for warmth and comfort.

The Solutions

The range of different heat pumps 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.

The Outcomes

The installation phase of the EoH project demonstrate 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.

Case Studies

742 heat pumps were installed within wide range of housing types and socio-economic groups.
