I will be removing our pellet stove from the basement and installing one on the first floor to hopefully gain some efficiency. We have an older house with a fairly enclosed floor plan on the first floor, which is about 1000 sq ft. The central stairs going to the basement and to the upper floors both have doors on them which can be closed off, I'm going to close them both because I'd like to try to essentially isolate the heat to the 1st floor only. Since the floor plan is not open and the stove can't be placed in a central location, I need to figure out a way to distribute the heat. Attached is the basic layout of the 1st floor (not to scale). The central staircase will be closed off and the bathroom in the center is closed off on three of the four sides. I've never liked having the central staircase/bathroom, but I think this just might work to my advantage since it could allow me to pull the air around the perimeter. What I was thinking about doing is installing a 16" shrouded window fan (which I have kicking around) in a door at the noted location. I would obviously have to cut a large hole in the bottom of this door to install the fan, but I don't mind doing this since the door itself was removed a while ago anyway. The fan would be blowing in the direction indicated. The large room next to the stove has a 7' archway right next to the stove itself so I'm sure that room will stay plenty warm, even though the fan should be pushing the air back towards the stove. The far rooms OTOH are going to be somewhat isolated from the stove... My question is do you think this single 16" fan at the proposed location will be enough to pull the warm air around the layout and keep the farthest areas warm? Thoughts or suggestions?
