The question is what the cop is at -20C though, which is a fairly common winter temperature, and you really need heat at -40

- wtallis 4y agoI was responding specifically to this bit: "Once it hits 0C the efficiency is very low, and by -10C is almost doing nothing at all." I've refuted that. If you want to discuss some more distant goalposts, I won't be able to offer firsthand evidence.
- SV_BubbleTime 4y agoYou are free to refute that. Doesn’t make it wrong. At -10C you are hardly pulling anything from the air, but you are spending electricity to keep your coils free of frost, as inefficiently as possible. Do you not know how a heat pump works in cold weather?
