What's special about 255K (0F) in relation to heat pumps?
- toomuchtodo 10y agoJust a number I picked from domain knowledge. Almost all newer heat pumps can still efficiently pull heat out of that temperature, although some more expensive ones can go all the way down to -20 - -30F ambient air temp. EDIT: If you're in a colder climate, in-ground coolant loops are preferred over an air transfer heat pump.
- martindevans 10y agoAh I see. So it's nothing fundamental, just a limit on our current heat pump technology.
