I was thinking about resale value of the house. My usage is mine, I'm just one guy. I figure the folks who will want my house the most are a largish family! When I moved in here there were 5 other people here, we each had our own bedroom! They are mostly small, mine is 9'10" x 9'10" with a couple closet type things in addition. One's a decent size bedroom, others not as big, more like mine. One's a peculiar affair with two doors, one leading to the back stairs upper area, the other to the front stairs upper foyer. I have a home theater setup in there, but it could be used for a bedroom if needed, it was when other people lived here. Well, I suppose I could just do what makes sense for me and let heating be solved by a buyer in accordance with their needs.
I have to research heat pumps, gonna check out videos, I figure a good way to get my bearings.
