Sounds great if it is so efficient. The final paragraph pretty much sums up my entire attitude to heat pumps. Please note that this is from a person who is actively developing the technology. I seem to remember that just as they started pushing heat pumps covid happened and electricity costs have tripled, which has contributed tremendously to killing the discussion imo.

>Not every home will be suitable for a heat pump. And not every budget can accommodate one, either. Yu himself says that the cost of replacing the gas boiler in his own home remains prohibitive. But it’s something he dreams of doing in the future.
