Hi all, I'm looking to heat the basement space of my Victorian sandstone house. It's unfinished other than some crap tanking that's flaking off. There's 3 rooms, good ceiling height and two windows. Anyway I was wondering if anybody had used an air to air heat pump as basement heating or could offer any views on whether it would be a sensible option? I was thinking about one possibly along with a heat recovery extractor at the other side of the basement.
