I hope your heating is more energy efficient than heating with electric light bulbs though!
(And it should be - worst comes to worst basic electrical heating can be effectively 100% efficient, and heat pumps can do better)
(And it should be - worst comes to worst basic electrical heating can be effectively 100% efficient, and heat pumps can do better)
The latter is 100% efficient (all energy in is delivered as heat). Heat pumps exceed 100% efficiency, and can deliver 3 to 6 times the heat energy as input, as they are moving heat from the exterior environment to the heated space.
