With the new Heat and Buildings Strategy encouraging the use of heat pumps - now is a good time to revisit the IOR paper "Why don't people install heat pumps?" available free here to download.
This paper considers why the annual UK installation rate of heat pumps is relatively low in comparison to other countries and questions the source of 'green' electricity required for a large heat pump fleet.
It covers electrically driven vapour compression air source heat pumps (ASHPs) for domestic and light commercial building sectors, providing on-gas grid and off-gas grid locations are considered, for:
- domestic hot water (DHW) plus space heating via low pressure hot water (LPHW)
- domestic hot water (DHW) plus space heating via warm air
This paper focuses on ASHPs, and doesn't include direct heat pump systems, because the number of heat pumps required to replace natural gas boilers and satisfy UK carbon reduction targets is not possible with ground source technology.
