My understanding of a heat pump is that it moves latent heat (vs sensible heat) from one side of the wall to the other. I got one, and there’s still a compressor outdoors inside the condenser.

That’s the point. The compressor’s energy use translated into straight thermal energy is about 1/3 the heat it actually moves (in or out). So using 1 kwh to heat-pump heat into your home gets you 3X the heat that an electric heating element/radiator could supply. :cheese:
“When used for heating a building on a mild day, a typical air-source heat pump has a COP [Coefficient Of Performance] of 3 – 4, whereas a typical electric resistance heater has a COP of 1.0. That is, one joule of electrical energy will cause a resistance heater to produce one joule of useful heat, while under ideal conditions, one joule of electrical energy can cause a heat pump to move much more than one joule of heat from a cooler place to a warmer place.”(Wiki)
