we've been reading alot about rocket stoves...interesting concept... Heating The Greenhouse Rocket-Stylepermaculturenews.org/2013/02/15/heating-the-greenhouse-rocket-style/Our new rocket mass heater is now functionally done. After installing a proper chimney, it really hums! Above is a video that we produced showcasing its construction.... |

That's a neat way of heating.
Another way that is even less work is one I read about decades ago, so I've forgotten the details.
It involved filling a pipe (?) with grape seeds left after wine-making. They produced enough heat while composting to keep the greenhouse warm in winter.

I love the Rocket Heater concept. I built a compost heater that warmed coolant and circulated it through a car radiator hung in my greenhouse. It was totally impractical. I'm now heating with a home-built pellet boiler using corn cob pellets. It circulates through a radiator with a fan behind it.
I like the idea of heating a mass with the furnace's exhaust. I let huge amounts of heat out through the stove pipe. I would imaging that a fan system could be installed on the end of the stovepipe that could function as a draw/draft. That way I could route the stovepipe around the greenhouse perimeter under the benches without having to worry about the pipe's gradual elevation for draft.
I can't quite figure out what your mass is made of. The end result looks like concrete, yet the in-process video looks like you're working with sand or screened clay.

Which is generally to say clay soil mixed with straw, packed on wet to shape. If you form blocks and dry them before using, it's adobes, Moses and the Israelites, all that. Used all over the world, although it tends to suck in earthquake zones, like I live in.
I'm wondering whether something of the sort could be used to heat the slab on which a house is built; something to mull.

In Korea, the floors were warm (wonderful after the freezing houses of Japan). There was a flue running under the floor, and they seemed to be burning a large briquet at one end.
I should have thought about putting one in before I had my greenhouse floor covered in slate.

Steev, we have radiant heat in the house. Love it. No stuffiness.

Radiant heat, do you mean electrically heated floors, or what?
