I have a 200 year old, poorly insulated, drafty 2400 sq ft house. Heating with oil currently, radiant floor mostly, 2 rooms with radiators. Oil bill ranges anywhere from $6000 - $10,000. Have a woodlot. According to the btu calculator on this site, I'm figuring 48,000 btu's for one floor, if doubling that will take care of 2nd floor, figuring I will need around 100K btus. I'm considering an outdoor wood furnace of some type, either gassifier or traditional. I'm in central NY and while a town nearby has banned the traditional outdoor wood furnace, not sure that that will occur out in the boonies where I live. What should I be thinking about and taking into consideration? Any opinions on the best way to go? I'm leaning toward an Econoburn 150. I know I need something easy to operate, not a rocket scientist and have little experience with burning wood. Any suggestions or thoughts would be most appreciated. Thanks.
