I'm real eager to get a hand fired stove to burn wood/coal for the first floor, but it's going to be very tricky venting the thing. Right now my only chimney is being used by the oil fired boiler in the basement. And there are so many doors, windows radiators to avoid on the first floor that the only thing I can think to do is to somehow power vent the old boiler in the basement, and cut through the living room wall to tap into the chimney. Does this sound feasible? I know that newer boilers can be direct/power vented, but this cast iron boiler is very old. I'm thinking that the cost of direct venting the boiler would be less than putting up a new chimney.
