how does a heat pump work?

Question

I don’t get it. How is cold, even freezing air turned into heat? How is it less energy consuming than other heating systems?

Answer 1

It’s less energy consuming because the amount of heat that gets moved by the heat pump contains more energy than the amount of energy needed to run the machine. As opposed to direct sources of heat, which usually simply convert energy in a different form, into heat energy.
