I've been lurking on this site for a while and have a few posts under my name; I have read comments from fireview owners saying that they are easily heating 2,000 sq feet in a tight house even though the stove is rated for 1,600. I am not sure of the life cycle of these stoves, but has anyone heard about the possibility of a new stove with a larger fire box. The house that we are looking at purchasing is a newer home with good insulation but the floor plan does not lend itself to being open and flowing. Though the fireview is an excellent stove and receives rave reviews, I'm thinking that it will have difficulty heating a house tlhis size.
