Ok Boyz N Girlz. I have offically begun my project. I"v gotten to the step where I need to start my 1 1/2 inch pipe so I'll be going today and getting that.
For my exhaust, I spent alot of time cuttin and shaping my brick around my exhaust so it would take less mud (refractory cement)(Ace Hardware carries it) to seal it off on the inside. I"ll use High Temp Caulk to seal it from the outside.
My idea of the exhaust is as follows...From the heater to the chimney, circle around back to the heater (parralled to first pipe) 90 degree up and back to the chimney, 90 degree up the chimney about 5 feet and I'll cut into my chimney for the out but to test it I may just un hook my wood stove and put the ehaust out there for starters.
As for the top of the RMH. I"m really thinking of having a steel plate milled to fit down in the top for a cap plate for 2 reasons....1- easy access into the heater if I need it...2- a ssteel plate wood make a much hotter top so the pre-heating of my water tank would be much more efficient....I"ll cross that bridge when I get to it.
It took five minutes of looking before I realized that I wasn't looking at some weird design that you'd pressed into the cob, I was looking at the bricks laying on the floor in a photo that needs to be rotated 90 degrees to the right.
