If/When I build my retirement home, it will only be 850ish square feet, so space for a wood burner will be hard to come by and it would be so small that burn times would be pretty short. I may do something like a pellet stove in the garage that I can duct into the house. An indoor furnace ducted in would be way overkill I think as would any OWB unless I heated the floor in the garage with it too.
