Wood heating requires a level of participation in loading, cleaning and maintaining of the unit.  The Econoburn™ gasification boiler will take up to 10" by 23" unsplit logs and functions as an incinerator in capturing all of the energy from the fuel.  It is made up to 1,000,000 BTU and has an A.S.M.E. stamp available.  With heavy duty steel construction and a dense refractory concrete lining in the secondary chamber, it is the best way to burn log wood.  Whether you have a woodlot, a source of stumpage or buy cut/split/dry cordwood, you will realize huge savings in fuel usage and labor.  You can buy a truckload (10-12 cords) of tree-length logs (10') and pay less than $100 per cord.    For the experienced wood burner, this is all part of good exercise, heating fuel independence and environmental responsibility.
