Actually, it does really good, but as always when you get new knowledge: More Questions pop up than are answered
I want to build a house in around half a year to a year. Building a house is a complete different philosophy in the states as it is in germany. I realized that in my terms in Miami. Here its more like you try to build it for all time being, and live there to the end of your days, and I'm quite comfortable with that thought. Following this way, I want to design all the installations to last a long time. It just doesn't fit in there, to build a stove with known issues remaining. But I expect those issues to be easily solvable by picking the right materials. Therefore I'd like to ask you about some more details:
*Which flue material did you use. In the videos it looked like standard stainless steel (1.4301 or x5CrNi1810). Did this material corrode? If yes, the problems are bigger than thought, but I dont really expect that. Its common flue material for oil and gas fired stoves.
*Did it corrode uniformly all over the flue, or is it worse in some parts than on others? Beginning? End?
I'll build the heat riser either from a highly heat resistant steel tube or chamotte. Whatever is available cheaper. I buy the stuff needed, and will not depend that much on what I find by chance.
Although cob as a building material has a long tradition, even today in rural germany ( timber framing => german "Fachwerkhäuser"), I'm not sure, if it will be part of my house, especially if not plastered over. I just don't know it from first hand living in such a house. I'm especially suspicious to the cob-bench, because I would expect it, to be easily abrased. Basically its just dried mud. Thus I'd expect having the dust of it everywhere, at the clothing, in the cushions, the floor, etc. pp... Maybe thats just prejudical, but I wouldn't take the risk, until convinced otherwise. Additionally i want to mate the stove with a water heat exchanger, to support the central heating and to use the heat everywhere in the house. Therefore my thermal battery will be a hot water tank.
