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.
