If you were trying to cool a room like with an air conditioner, yes. Heat pumps literally work in reverse, bringing heat in more efficiently than any resistive heater. They output more heat energy than they use, as they are moving heat, not generating it.

They're not only for heating though, they can cool as well.
I guess I interpreted the comic backward; they're heating the room not cooling it.
