Kazagashira Niwa

Here the latest pictures. Almost ready, still a bit plastering to do. It is functioning sweetly. Good draft. No smoke coming back whatsoever, also not in the beginning. It doesn't burn super super clean though. I think because of the smaller system size, it doesn't reach high enough temperatures for a total burn. Every time I add some wood it produces a bit of smoke until it is properly on fire. Smoke is barely visible outside.  The total mass became about 7000 kg. And it does keep warm for a couple of days, after a 4 hour burn. Still I need to see the performance when the winter kicks in completely.

Update on the stove: Design has been made simpler, and came back into the mainframe of the house. Since there are so many burnable elements in close proximity of the planned stove, I had to make some compromises. Taking as much wood away as possible. Rebuilding three walls with cob. making a shield to protect the paper doors that are next to the stove. Adding air ducts to take away potential heat from the support beams. And in the end I could only fit in a system 15 cm in diameter instead of the 20 cm that would be stronger.
