Heat isn't created (other than small friction byproducts). Heat is moved. If you go stand near the outside of an AC unit you'll feel it blowing warm or hot air. That's just the heat being moved from inside.I've been reading about how heat pumps work for a long time.
I know they harvest the heat from the outside air, even when it "cold" outside but..........
Seems to me most the heat is generated when the gas is compressed?
A hear pump usually has a greater than 100% efficiency. Seems like it violates laws of thermodynamics or what not, but true. Ots merely moving heat around not creating it like burning fuel or resistive electrical heating.
More expensive initially, but often good in the longterm. Using less fuel or electricity is good for the environment too.
