Fireplace Heater Tube
(OP)
Were are building a fireplace tube heater.
Need to know the material and wall thickness recommendation.
The fire (wood) will be in direct contact with this.
The photo is something like what we are building but not exactly this shape.

310 is great, but will be expensive.
309 would work also and should not cost as much
I would prefer 430 over 304 but either should work fine.

RE: Fireplace Heater Tube
Thank you, I figured that would happen.
One other quick question is your thoughts on wall thickness??
RE: Fireplace Heater Tube
The lower part is heavily loaded, but not very hot and you can provide support. The upper part that is the hottest is only trying to support itself. A couple of lateral tie rods across the back and top would allow the cooler outer tubes to assist in supporting the center ones.
A heavier wall may be stronger and last longer with scaling, but it will suffer more distortion from heating and cooling and have a greater risk of cracking from thermal cycling.
You need to allow some distortion as it is less damaging than cracking.
