Hello folks, Total noob to these forums but i've just started seriously looking into an alternative-to-oil heating solution for my very aged farmhouse...and I came across your little corner on the net and got hooked on reading all the posts. Question: Is there such an animal as a wood-fired gasifier that can be used with an existing forced-air ductwork system, or do all gasifiers rely on a boiler hooked to water radiators. Is forced-air more efficient than radiator-based systems? I would really have liked to go the geo-thermal route (I have the real estate to do it) but it seems it's WAY too expensive for my aging home. All that being said, I also have an indoor dug well (about 13 feet deep, 36" across) that i do not use any more for my water supply - can it be used as a storage device for any kind of heating system I choose to adopt? My current woodstove is nowhere near air-tight and I go through ALOT of wood (from my own lot) in a winter - it uses a massive stone chimney though, that once heated acts as a terrific radiant source of heat. Thanks in advance for any help/advice received! Patrick.
