Greenhouse construction with a rocket mas heater, including an excellent demonstration of the rocket mass heater sideways burn. The greenhouse construction class is taught by Ernie and Erica Wisner, featuring the rocket mass heater techniques of Ianto Evans (of cob cottage company fame). I cannot think of a better approach to greenhouse heating.
This is the first phase of building this greenhouse. The focus is on the steps of building the rocket mass heater.
This video has an excellent demonstration of the sideways burn - or fire burning sideways.
Since this will be an oehler style solar greenhouse, then it probably won't need much heat. But it will be a bonus. And the heated air could also be piped into the house.
A rockey mass heater is typically 10 times more efficient than a regular wood stove. And 20 times cleaner.
A mike oehler style greenhouse construction is probably the most efficient greenhouse known.
