A heat pump does not make heat — it moves it, so it can deliver several kilowatts of warmth per kilowatt of electricity. The coefficient of performance is that ratio, capped by the Carnot limit T_hot/(T_hot − T_cold). The colder it gets outside, the harder the pump works and the lower the COP — but even at freezing it beats a resistance heater several times over.

Heat flows through a wall like current through resistors in series. Each layer's thermal resistance is its thickness over its conductivity; adding them gives the total R-value, and the heat flux is the temperature difference divided by it. Insulation, with very low conductivity, dominates the R-value — the steep temperature drop shows where it does its work.
