Heat Batteries
The question
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential merits of using heat batteries for households who experience challenges in installing a heat pump.
Answered by Miatta Fahnbulleh
Heat batteries are one of the most promising alternative electric heating technologies, because they utilise time of use tariffs, do not require outside space and are cheaper to install than heat pumps in some circumstance. However, heat batteries are also less efficient than heat pumps and will therefore use more energy to meet the same heating demand. This can add to the burden on the electricity network, as well as resulting in higher bills for property owners. The Government will continue to make further assessments of heat batteries as the supporting evidence base develops.
