First post from me. Hello!
This was my first RMH build. Heated a 12 sq. m. cabin wonderfully, but the flue exited top back, so in hindsight it was quite inefficient:
Second one for a steam room / sauna; same design as first, but bigger burn chamber; also works excellently:
Third project on the cards and I want to increase efficiency by adding a brick bell. Here is my extremely technical drawing:
I have played with the firebricks for the riser; imagine a brick bell on the left, as in the design drawing:
Here is the burn chamber:
Is the hole at the top of the riser big enough, or too big, for the push into the brick bell?
