I see. Yeah you could definitely use the thermal mass for a place for drying pots. I came across a restaurant that lined their patio with it and used it for booth seating. I actually dug mine up :-/ My studio is very long and skinny ( 10ish by 40ish) and I decided after a few months to pull it up because the heat dissipated by the time it got to my far wall where my wheel is. The place where I put it was the only area where Theres no foundation. Its the same in the summer with cooling, I have fans but the flow stops by the middle. Its in an old pole barn. The other reason why I switched is because we do all our car work so we have a ton of waste oil from all my families oil changes. Plus I do smelt from time to time and I have need of a waste oil burner. Waste oil heaters can crank out heat so thats my future setup.
I agree with the clean burn and low temp if any exhaust. Btw I used Kawool for my inner burn chamber and old salvaged fire brick from a torn down house. There is yet another option. Its basically very close to the same idea as the rocket stove. It was invented in Europe back in the day during a wood shortage. Its very decorative and Im sure you can fabricate one on your own. It uses very little wood and burns crazy efficient with long lasting heat. The Kachelofen. Masonry stoves for another name.
