Hey everyone!
This is a good bunch of info.
What I'm really after though, is  examples or discussion of RMHs used for infloor heating. I don't mean heating water to circulate in a conventional infloor tubing system. I mean running the hot gasses directly through an earth floor of some form. I've so far managed to find one post here mentioning various ancient methods from the Romans to the Koreans. BUT there is not much mention of modern interpretations. I would think making use of arguably the most massive part of a house to store heat would be something people would be talking about and at least experimenting. If you know who's doing, talking, or experimenting with this method please point me in the right direction. Thanks permies!!

Hi Harry,
I am getting ready for just such a project. I have been scouring the interwebs for ages trying to gather all the useful info.
The best resource I have found so far is the Aprovecho institutional rocket stove plans. There is a YouTube playlist of an example build. While it took some digging, I managed to find a few documents which provide enough details to go forward with my own design and build of the stove. The main issue is that there will always be some customization needed to match your materials and pot along with any other requirements you might have. You can find a lot of info on riser and insulation material choices here on the forums. Also bear in mind the effect of the extreme heat on whatever your pot is made out of. I am planning on coming up with some kind of replaceable diffuser for the top of the riser to prolong the pot life.
