The concept makes sense, but I'm not sure the numbers work out. Heat pumps are pretty efficient, something like 300 to 400%. Are you really going to use less than 25 to 33% of your living area and also not provide any heat at all to the other areas? Also, with forced air heat pumps, you can usually adjust the registers (air vents) to reduce the flow of air to unused rooms.
