Rocket Mass Heater – Design and Build

Rocket Mass Heaters (RMH): Heating for the Self Reliant Alternatively-Minded Individual

Our RMH workshops are usually 2½ intensive days dedicated to fire, alternative heat, the principles of thermodynamics, thermal mass vs. insulation & and a whole lot of hands-on experience so that you can design and construct a system suited to your needs whether you want to heat an out building, workshop or green house. The idea is that with very little heat energy input, the mass of the bench (we show you how to build with cob for this part) creates a battery bank of heat that will keep a space warm when the stove is not in use.
