Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate her Department has made of the proportion of off-grid homes which are suitable for a hydronic heat pump.

A home’s suitability for a heat pump depends on several factors such as sufficient internal and external space, peak current draw of the grid connection, and the home’s peak heat loss.

Evidence suggests the vast majority of GB homes have sufficient insulation and electricity connections to install a heat pump, considering developments like heat pumps operating with higher flow temperatures enabling installation in less well insulated homes.

We have commissioned research on understanding different approaches to decarbonising complex housing archetypes, including alternative low carbon heating solutions, and expect it to be published in due course.
