I searched but couldn't find a topic that addressed this. I want to put a rocket stove mass heater in a skoolie, but don't want the weight of fully conventional. Can hempcrete be used instead of the mainstream materials?
The mass is the point; using less-dense material will probably reduce the heat-storage capacity and possibly insulate instead. I would just use a thinner layer of cob or masonry around your heat exchange element, and enjoy the reduced footprint.
No thanks. We have all the government we need. This tiny ad would like you to leave now:
