wood stove + rocket mass heater = hybrid

http://permies.com/stoves http://permies.com Ernie Wisner ( http://www.ernieanderica.info ) has built more than 700 rocket mass heaters. This time he creates a hybrid between a conventional wood stove and a rocket mass heater. The first step is to try and get the wood stove to a cleaner burn. Ernie succeeds in getting a much cleaner burn, but not (yet) as clean as a rocket mass heater. Next, the work is to try to heat the same space with less wood. The wood stove alone was using five cords of wood each winter. This prototype was able to reduce that to 2.5 cords. Ernie thinks he can get that down to one cord. He also thinks a proper rocket mass heater would get down to half a cord. At the very end, Ernie talks about how a conventional wood stove can get a 75% efficiency rating in a lab, and operate at 2% efficiency in the home.
