Dear Ernie, Erica, and other RMH enthusiasts,
After reading this thread, I understand that rocket cook stoves and space heaters under 6" can work well, but RMHs with long runs of exhaust under 6" often don't. What about an RMH like
Kirk Mobert's Cyclone? It seems to have a relatively short exhaust system. Do you think something like this could be scaled down? If so, to what size?
