I have a welder, an angle grinder, cutoff tool, etc and a bunch of non-galvanized water tanks.
I want to purchase a 4"x4" length of Square Tube steel (see the video here from a guy on ebay selling them https://www.youtube.com/watch?v=9ks8HQothtk#t=76
Here is what I want to do:
I want to take one of the water tanks and cut it in half and weld it after I am done constructing it. I want to cut a hole for inserting wood and perhaps do a J-Tube.
My questions are in the lengths I should cut and the size of the tubing.
My place is 200 sqft tiny house stick frame.
I want to do a J-tube, but it doesn't matter.
In general, is using steall square tubing that is 4"x4" to big or to small? There is 5", 6", and 3". Does the size matter? Does the inserting-wood-side need to be bigger or smaller then the exhaust or insidie tube?
What should be the size of the inside tube pipe?
What length should be the tube inside the steel water tank?
What clearance should it have from the top of the water tank?
What clearance should it have, if at all, at the bottom of the tank?
What should be the length of the side insert where I place wood?
How far out should it come from the water tank?
What should be the size of the hole for the exhaust?
Should the exhaust be above or below the firewood insert area?
What should be the thickness of the insulation around the inside tube? I want to use Perlite.
Should it be 1", 2", 5"?
What should be the cubic area inside of the water tank in general for a good burn?
Can I put mass inside the water tank to hold heat?
Can I pipe the exhaust sideways outside of my building without going through my roof?
Please help me figure this out.
