Hello to all: First post for me, & glad to find this www.hearth.com website & forum. I could use some info from those with experience, as follows: We want to add an INDOOR, add-on wood fuel boiler system to our existing Hydrotherm Oil Hot Water boiler (baseboard heat). Friends tell us we have the "perfect" basement for this kind of wood add-on system that will likely take over as our primary/main heating source. We're tired of paying for rising oil prices & don't want to participate in that part of the economy anymore. Our house/set up: - The new, wood fired boiler will sit nearby the existing oil hot water Boiler, and will share the same chimney (since they won't run at the same time. Need to check building code & Insurance to be sure its OK). - 2300 SQ. ft. house, 100 years old, moderately insulated (Attic & walls have had additional insulation blown-in, newer windows in most of the house). Initial web searching and found just a few options ... * The Alternative Fuel Gasification Boiler (Dunkirk, NY) appears to be the "Cadillac" system out there. This seems to be the best technology (cleanest & most efficient burning, low emissions, etc.). I phoned & they say this "gasification" system burns 2/3rds LESS wood than other wood fired boilers. The downside of this system appears to be that it is quite expensive ($6500-100K-BTU, to $7500/150K-BTU unit). It is also extremely heavy, and at 1500 lbs., I don't know what I can use to wheel this thing into my basement. I guess we can figure that part out ... if I can afford this thing. * Another we've seen for sale is a Thermo-Control Model 500 Wood Burning w/Hot Water Coils, about $2100. 125K BTU is adequate for 2300 s.f. house. * Another we've seen for sale is an "Dakon FB 42 Cast Iron Boiler". It appears to be a Czech manufactured unit. Found it on eBAY, Min. bid $3350. Not much info provided otherwise, so applicability to our house & set up is unknown. * Also found from same seller on eBAY is "EKO Line Orlan Boilers". This appears to be another wood gasification unit, though not much info provided. Is anyone familiar with these, or are there other recommended wood-boiler add-on units you can offer info on? Many thanks.
