I would like to build a RMH under a wooden staircase. Can I encase the barrel inside the masonry under a staircase? It appears in every photo/video example all of the stoves I have seen have exposed barrels. And my situation, could I enclose the barrel in the masonry such as is found in a traditional fireplace? Would enclosing the barrel cause the rocket mass stove to not work properly? That location seems to be ideal to allow the heat to rise from the lowest level to the second and third levels of the home.
I have posted this in other threads, but would like to add it here.
I built a 6 inch RMH, and it so happens, that the barrel was located 3 feet away from an electrical panel. Once the mass dried out, and the stove was "rockety" - it was normal too see the top of the barrel hit 1100 F - hot enough to get the face of my electrical panel too hot too touch - just from the radiant heat coming off the barrel after an extended burn.
You need the barrel to radiate the heat away from the stove - that gives you your draw up the chimney - but when my plastic vapor barrier started to crinkle up and melt - ya know your in trouble ....
