I have a Vermont Castings Resolute circa 1978 I think. Two doors. I am trying to heat the first floor of a Cape house so the two rooms upstairs are with closed doors. The stove is at one end of a 25x15ft room that has two openings one into the kitchen and one into the dining room and wall betw those openings that is about 12ft on. On the opposite wall are two huge windows and a door. The ceiling is a low one so maybe 7 or 8 ft. WE have trouble getting the room up to 70 degrees and if we do it takes some hours to do that. I am thinking that maybe the back of this stove is clogged(where secondary smoke goes through?) WE love the heat that a wood stove provides so am thinking maybe it is time for a new stove. Saw a Woodstock Soapstone stove and like the idea but not sure it is the stove for me. They have new models that are hybrid and they have a steel stove that you can have soapstone sides and firebox. I would say our home is about 1800 sq ft, no basement or attic and want to be able to warm the downstairs to 68 at least. Soapstone seems to warm up slower but then keeps the heat longer so wonder if it s even a choice for me. You experts are great and welcome your thoughts.
