I'll stick with gas, everyone I know with ASHP says it can't cope with sub zero temps and it's cheaper to have electric heating when the temp is that low. What about ground source heating does anyone have experience, cost etc. I went to a health spa in Switzerland that had it heating 3 Olympic swimming pools it was amazing.
Can't comment on lower Keith but admittedly surprised ours comfortably coped with morning temperatures of -8°C over last two winters. It's drawing just over 2.5 kW then but heating six rooms plus hot water. Admittedly the lounge morning temp dropped briefly to 18°C though
