Hybrid heating systems currently make up only a small proportion of the UK’s domestic heating market, with less than 2000 being sold in 2021. The Government plans to use an upcoming consultation to explore the potential future role of hybrid heat pumps.

Where a hybrid system is installed with a fossil fuel boiler the emissions savings depend on a number of factors including their usage, design and the thermal efficiency of buildings.
