If you're going to insist that air source heat pumps don't exist then yes, heat pumps are very expensive. They do however, and especially in non-Scandinavian Europe, they will work fine.

  Well then, I take it back that it isn't a shared definition in that sense. But it's a pity, because the air source ones are basically AC units which can also run backward to heat your home, and if more people knew that, they'd install them.
