Since it is a bit slow in the forum how about a little survey. Indoor gasser users only! List how many full cords of firewood (4' x 4' x 8') you used last heating season (October 1st - April 30) The square footage of your house, brand of boiler, storage or no storage. If you used an traditional outdoor boiler in the past, what was your savings on firewood consumption using the gassifier?
