I am a prime canidate for a RMH. I've burned wood as my sole source of heat for over twenty years. I want a RMH ... but after reading dozens and dozens of articles and watching video clips, etc., it seems way too artsy-craftsy for me to attempt. Seems every heater is an experiment. Or the last one had this problem or that problem so we are doing this or that. I read your short write-up about the types of tubes. Every one had a fault. Or couldn't be found, or costs a fortune, etc. Makes me tired just thinking about it. Don't get me wrong, I do a lot of building. I single-handedly put a foundation under a 1905 house and turned it into a two-story duplex. I built an aquaponics system. I built a two-story pole barn. I just finished an outdoor ADA-compliant shower. But the million variations, and multiple failure points of a RMH have kept me from the attempt. I don't read much about them any more, and probably will never build one. I watched the short video you made for your kickstarter when you first advertised it and didn't find it encouraging. Sorry
