Yeah I had a heat pump engineer come and do a survey and heat loss calculation, and the conclusion is that I would require 2 pumps to produce enough heat. I’d be looking at around 20 grand upfront for that, after the government grant being applied.
For that money I could probably replace all windows with triple glaze and add insulation, and come out a lot more efficient than replacing the gas boiler.
In fairness, that would also likely get the house ready for a single pump, and when electricity prices cease to be kept artificially high it will probably be economical to make the switch.
Efficiency =/= load capacity
Which can be solved by installing a bigger heat pump. No boiler can compete with 300% efficency.
Which brings us back to efficiency, this time cost efficiency.
If the heat pump costs more than insulating would have, then obviously you’ve not so much solved the problem but rather made it bigger.

Fair; can’t argue with that
