RMH thermal bench question  RSS feed

I have a question that seems to me to have an obvious answer, but so many folks on this forum offer experience I just don't have yet, so here goes... The first floor of my house is about 30 inches above the garage floor (attached garage) so I walk up some stairs to get in and I have a fairly large area I'd like to section off for a mud room. I'd love to put a RMH in the mud room, but being in such a small space it would be nice to have the thermal bench inside the house, on the other side of the wall. If I build a RMH at the garage elevation in a space that is currently open to the entire garage, could I run the exhaust duct through the wall and make my thermal bench inside (about 24"-30" above garage floor) and then exhaust outside? Is there any foolishness in thinking I can exit the RMH bell to an outlet and then duct the warm exhaust to a remote thermal battery at an elevation between 2 and 3 feet above the outlet of the bell? Would I be working against the "downward pushing" action of the exhaust after it reaches the top of the burn tunnel and then moves toward the opening at the bottom of the bell? The idea seems too obvious to me not to work, but I've been very surprised at reading other postings and am throwing it out there.

Thanks in advance, this forum ROCKS!

Dan, if I understand you correctly it should work just fine.
the bottom of the "Bell" or "Barrel" being lower than the thermal sink, should cause a better drafting situation(hot gasses rising) with less back burn and smoking.

Thanks Tarkus, I know it teders on the edge of too obvious, but I've had trouble with a woodstove in my basement and never could figure out why getting it to draft was so hard until I started reading this forum. I think it had something to do with negative pressure being in my basement, that is the best I can guess. However, I agree that helping a system draft by having the thermal bench elevated higher than the burn tunnel should help, especially after watching some of Ernie's videos and seeing other under-the-floor thermal battery designs. I've made assumptions before and have found myself to be eating crow as a result, so I put it out there for folks with more smarts and experience to de-bunk. Much appreciated, this forum is such a great resource!

I agree whole heartedly, it's much easier with the support of others of like mind and intention.
Good luck

If i may say something, it will work, tho, to pamper the fire, you"ll have to get back to the mud room, may be every half hour with a six incher. And to charge the bench, it takes some time. So, maybe, you should look into eight inchers or horizontal feed which outputs more heat, and lasts longer. Tho, you still won't have the quick heat from the barrel.
