Heat pumps are a crucial technology for the decarbonisation of heating buildings. Their popularity is increasing in the UK and is integral to low- and zero-carbon solutions for both new and existing buildings.

This insight paper summarises ABC’s programme to date of testing the performance of domestic heat pumps for space heating. It includes an assessment of commercially available heat pumps and the development of thermal modelling of CO2 heat pumps and their building application, including the application of thermal storage.  The paper also describes how heat pump design incorporating new technology to increase performance efficiency can be tested using ABC’s laboratory testing facility.

The document concludes with a summary of insights gained and some pointers for future work. The learnings from the project, as well ABC’s heat pump centre and demonstration houses,  could then be used to develop and test future heat pumps for both existing and new housing.
