I am considering a pellet/multi fuel stove vs wood fired outdoor boiler. House is 3200sf walkout ranch which is getting new windows, doors, tyvek and new siding currently (almost done). I would like to put the stove in the basement family room in a location which IS central to the floorplan. Unfortunatley my stairway is at one end of the house, not in the center. However the stove would be placed against the wall to my mechanical room where there is an unused 4" B vent from my old 80% furnace. I would like to add a cold air return vent to my cold air return plenum (happens to be right where the stove would be placed) above the stove to pull warm air from the basement and circulate to the upstairs using the furnace blower. Also is it possible to coil some copper above the fire box to help with heating water? If this sounds like it would work ok, what size stove and what brand to look at? I like the look and feel of a stove in the house and my installation would be pretty easy. I dont really care for the look of an boiler in the backyard and I'm pretty much broke from the windows, doors, tyvek and siding.
