Heat pump = air conditioner that cools the outside and dumps heat inside.
More efficient than radiators (which are always 100% efficient) because of a loophole in the laws of thermodynamics.
Though most heat pumps are also air-conditioners. All it takes is a 4 way refrigerant redirection valve manifold. Heat pumps don't just advertise it as headliner, since the main point is energy savings in the heating. One doesn't get energy savings in the cooling. When switched to cooling, its just an air-conditioner. Same old power hungry airconditioner.
Heat pumps just list in the side sentence "oh you can also run this heat pump in cooling mode in addition to heating mode. Note: the inefficient energy use, when being run in cooling mode."
