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 like an air conditioner running in reverse. It generates cold air outside with an evaporator and pumps the vapor indoors where it gets compressed to generate hot air inside with a condenser, before pumping the condensate back outside to continue the cycle.
