Be careful, you're angering the thermo gods! If that was true, I would simply use an air-conditioner to heat my house. Cool, the outside and move the heat inside. In reality, you have the efficiencies backwards. Cooling is more energy intensive than heating.

It's true, and people do. Install a heat pump, and save your traditional heat source for when it's sufficiently cold outside.
