I am deciding what to buy, a tarm gasifier or a regular outdoor boiler with gasification or not. Which boiler manufacturers should I stay away from, I compiled a list and would like to here about the pros and cons. Central Boiler, Shaver, Heatmor, Northland Outdoor Wood Furnace, Greenwood, Sequoyah, Empyre, Hawken Energy. I was thinking about a gasifier from tarm but good dry wood might be a problem 100% of the time and when I am working the 16 year old boy will fill it or my wife. Alot less wood splitting also. My house is 2700 square feet, well insulated, and I have a 79,000 BTU Utica boiler in it now. I have a 36 x 40 garage I may want to heat up to 45 degrees or so in the winter also.
