They now (as of 2018 I think) make Extra Low Temp heat pumps, which can work down to -15F. I think that makes heat pumps practical for a very wide variety of temperate climates.
- SketchySeaBeast 8y agoI see they do, but their BTU's are very low - I see the Fujitsu RLS3H, which goes down to -26C only outputs 12,000 BTU at that temperature. To heat a house at that temperature you'd need 5-10 (if not more) of those.
