I totally appreciate your reply, and I do understand the 6" system. But I like to tinker and experiment.
I want mass, and I want a small portable system for easy removal and small indoor space saving usage.
My ultimate goal is to find a way that "tiny homes" or trailer homes, can have a small efficient mass wood stove that fits in the small footprint of their dwelling.
For now, I'm playing with a 4" unit and I think I've figured out the stack, but I'm wondering about the burn tunnel length.
Perhaps someone knows about small "tiny house" systems...
thanks again for any and all responses.
I can take constructive criticism.
