The Government is collecting data on the in-situ performance, carbon reduction and use of hybrid heat pumps on the gas grid through the Electrification of Heat Demonstration Project, which has installed 153 hybrid (including five “compact hybrid”) systems. 75 homes were installed with hybrid heating systems under the Freedom Project over 2017-2018. Hybrids were also installed under the Optimised Retrofit Programme by the Welsh Government. In addition, seven compact hybrid heat pumps have been installed under the Hycompact project.
