Thanks al so in therie a 12x12 is just to big. Then i will ask. I want to run the largest feed chamber i can with all your knowledge what do you think is best. I can only put it in my basement unfortunately. I am using solar fans to move warm air up stairs. Thank you for your help

Good morning. I have 12x12 clay flue pipe. I would like to use it to build my whole house rmh in my basement. I do knkw i need fresh air intake do to being in the basement got that covered. What i need is the dimentions for the jtube and barrel. Im going to use twin 8in round exhausts so it will breath. But the burn chamber is my issue. My 6x6 up north works grate but i cant seam to wrap my head around the 12x12 size. Thank you for you help

So my question is how to determine sizing of the j it self

This is how I'm looking at it. What would be the correct formula to build it

Stainless steel. I have the opportunity to build out o's stainless. So should I build it all out of 10x10in square tubing

I Am attempting a large heater. Using a 10x10in riser but how to Calculate all the rest. My idea is to manufacture feed box cross tube and riser out of S'S my mass will be 30ft long with 3 elbows. Please help. Thanks
