Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, for what reason the Government's policy support for heat pumps is targeted at heat pumps which heat water rather than those that heat air.

BEIS analysis indicates that hydronic heat pumps, which use hot water to provide heat using a central heating system, are a more cost-effective means of decarbonising heat in the majority of homes and businesses across the UK. Therefore, the Government anticipates hydronic heat pumps will be the principal means of decarbonising heat in homes.
