I just found this site thru reddit, where I was reading about rocket stoves. I love the idea of a RMH, but I'm wondering how big should I make it for a home (I live in a log home btw, if that matters). We don't utilize the basement that much, so I wanted to initially put it on the first floor. But, as I mentioned its all wood flooring. So, my question is should I build it in the basement, if so will the heat just radiate up enough to heat upstairs? I'm comfortable with 69-70,and I'm in the MW so winters do get to low 20's, sometime in the teens, rarely below zero.
So, main questions are size? should i incorporate my existing ductwork? Is that even possible? Is a bigger barrel (55 vs 35 gal) better?
Edit: I found used galvanized stove pipe, can I use that?
