BigPhillyStyle interesting info on your topic. After 4 hrs of getting the Juno #215 Potbelly, which is 32" tall with legs, about 18" stove chamber only and 14" wide, stoked up with a full hot bed of coals, the temp in Smokehouse only reached 200 F once. It mostly stayed around 195 F. The PB itself reached temp from 675 F - 700 F.
Its amazing to me with the temps of the PB in a 4 X 5 X 7 room , with door closed, that max of 200 F was all it got up to. I would have guessed before the test that I could have got at least 225 F.
My question would be to some of your "long timers" here on this forum, is there any use in me even trying the propane burners in the Smokehouse? I don't see the propane burners reaching temps higher than the Juno PB got to.
