I've heard this several but don't really understand the rationale. Can't you just put in a bigger heat pump? Or top up an air to water with an air to air?

- sgt101 2y agoI think that the issue is claimed to be that the pump will use lots of electricity trying to keep up with the heat escaping and therefore will not be economical.
- RobinL 2y agoBut the same is true of gas, and in the UK at least they cost about the same per kWh of output heat (electricity is more expensive, but this is balanced out by the higher efficiency of the heat pump)
- sgt101 2y agoI think that this is a new(ish) thing though. When the UK was pulling gas out of the Irish Sea and the North Sea for domestic heating gas was much much cheaper than electricity. Then gas started being used at scale for electricity generation (the so called dash for gas). Then we moved to just in time import gas and things got very expensive. So - things have changed.
