The least efficient/most expensive way to heat air.
Care to elaborate? A space heater draws 1500 watts of electrical energy and converts it into 1500 watts of heat energy that is released into the room. That seems pretty efficient to me.
A heat pump can take 1500 watts and use it to pump 3000-4500 watts of heat out of the ground loop and into your house.
True. It's still a middling way of heating things, though, not the worst. A wood furnace would probably be the worst that still gets used.
And, uh, most people report a heat pump won't work at -35 right now anyway. I'm sure better ones are coming.
