Hence furnaces. Unless someone's managed to create servers which become cooler upon load, I'd assume these boxes wouldn't be able to substitute for heat pumps.
Just 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.

Heat pump.
EDIT: Unless you live somewhere where the ambient temp goes below ~0F, get a heat pump.

But in general, I agree with you. :)
What's special about 255K (0F) in relation to heat pumps?

Ah I see. So it's nothing fundamental, just a limit on our current heat pump technology.
