I think I have the floor supports covered, I think I'm going to build 3-4 more piers under the house and cross brace the area.
However What I am looking at is the heat near the floor and wall.
I'm thinking of doing a combination of things I've seen done. from the Sub floor up.
Radiant barrier (foil or other) facing up.
1-2 inch risers to support
cement Board (hard backer board doesn't burn)
Ceramic tile board. (also doesn't Burn)
Build a 2 inch Lip around Ceramic board
Fill it with perilite or some other insulation if there is better.
Build the J tube on this
build a form around the J tube and also Fill it with Perilite.
Against the wall right next to the J tube I'd replace the Drywall with Cement Board or Ceramic Tile Board. There is no Insulation in this wall Just 2x4 and drywall.
Behind where the Barrel would Sit I'd like to do a wall of red bricks to bounce the heat and give a nice look, do I need to put anything between the Bricks and the wall?
How hot does the bell area for the ash pit get on an 8 Inch system?
I plan on an L shaped thermal mass, from the start of my feed tube to the wall is 11 feet then from that corner out is 6 feet.
Aside from the part of the wall that is next to the Jtube I was thinking about along the 11 foot side removing the Drywall to a couple inches below the top of the thermal mass. There is a room on the other side of that wall that doesn't heat hardly at all with my current wood stove, even when I make the rest of the house uncomfortably hot that room is cold. So my thinking is that the heat can escape into the wall cavity and warm the rooms drywall on that wall which would in turn warm that room some. I already have this effect to a small portion as my Wood Stove sit on the other side of this wall and when its been running a long while very hot we can feel slight warmth on the drywall directly behind the stove pipe.
Now the Pipe, I have approx 35 feet + drag of 6 elbows giving me about 65 feet drag, the exit pipe will be in a low pressure zone when the wind is blowing so shouldn't have wind issues.
Do I need to make the heat riser taller then normal to overcome this much drag?
I hear that 50ish feet should be max for a 8 inch standard system.
