http://richsoil.com/stoveshttp://permies.com Seven examples of the rocket mass heater draw and/or the sideways fire / burn that is an essential component of the rocket mass heater. You can see the fire / flames actually going sideways. And you can see the smoke re-burning and making the rocket sound - sometimes with fire coming out the top of a chimney.
This shows several examples of dry stacked bricks that will eventually be a rocket mass heater core - complete with fire dmonstrating the sideways burn and the draw.
Appearances by Geoff Badenoch, Caitlin Elder and Ernie Wisner.
