Some how in our move I lost my copy of RMH book. I am wanting to build a earthsheltered green house this fall and want to build in either one or two RMH. I can not remember from my reading how long of a pipe run I can make with 8" flue in a cob bench. I remember that if it is too long there will be too great of a temp drop before exhausting. The other question is that for the size of the green house would I be better to have two RMH or engineer up to a larger diameter and length to heat more space? your thoughts or opinions would be helpful.

Your answer.. It depends.
Somewhere between 30 and 50 feet.
It ain't in the book, but you can go further if you step down in pipe size a little.
I have NO IDEA exactly where to place the steps, no one's nailed that ratio down yet..
I CAN say that I've seen it work and that a little experimentation will answer the question for your particular need..
