I used to live in a place with a heat pump. In the winter it warms ever-so-slightly, and if it’s really cold out, it must pump for a long time to raise the room temperature at all. But that means blowing air for a long time, and then the wind-chill factor on your skin outweighs the warming. I used to be embarrassed by guests asking me why I had air-conditioning on in the winter. (Not much related to the cartoon, but my hatred of heat-pumps overcame me.)
