The complexity isn't just all the systems and the rest of it to get radiant heat, for instance water isn't going to work. The complexity is matching a stove designed to produce say 2000+ degrees F with the need to heat water only a little above room temperature (well at least where it will be heating you). The way the mass heater squares that circle is by having a large mass to absorb the heat, and gradually release it, but to do that for water/antifreeze is a little more tricky, to say the least. The RMH just (we are told) works: the heat lasts overnight, the creasote, and gas leakage aren't a problem. Low on pollution and cost to feed, the only problem is that is all it does. Mess with it, and it doesn't work. There are so many superlatives attached to it, one might think it was a universal solution, like a tech controlled gas burner, can be in a forge, a stove, a dryer, you name it. RMHs are pretty much the one thing.
