Diddums trussed roof and painting,
Diddums has been sitting the barn for a few years, thanks to to surgeries, new businesses and basic life events. Found some yearning to get to working on him again this summer... IF you'd like to ...

Not getting the images in your last post. Use this, it's painless: Photoposting is great I think one of the Mods wrote that app and it is brilliant.
Heaters--My heat comes from the fuel I burn through an appliance with holes in it to distribute the gas and burn it in a certain location. The amount of heat is limited to the BTU content of the fuel and the output and efficiency of my heating appliance. IOW, wrapping metal around the flame will not produce more heat. It does offer mass, though. If properly made (I'm liking that tubing idea), it will retain heat and give off heat even with the burner off. More mass means more even heat, too. FWIW, the last three or four freestanding heater installations I've done in an RV, all had tile surrounds. More mass = more even heat.
Distributing the heat off the appliance means fans for me, 12V computer fans is what I use. Since we can now insulate these trailers well, it doesn't take extraordinary fuel burning to keep even heat inside one. My 20K Sportsman heater is typically on idle or pilot after heating the cabin.
Repo, here's one idea I had for a freestanding heater: use a 30 gallon grease drum for the outer skin. Fashion a bottom plate that holds the gas ring from a discarded water heater. Vent can be cut near the top for exhaust.I have an old box of orifices here but an orifice change may be needed if using a discarded NG gas ring.
Typically, propane gas fired appliances need a vent stack with make up air flues. The hot exhaust gas exits the flue better with an additional amount of air drawn into the stack. I have seen a few direct piped to the outside and your heater, if small enough, may operate like that. For mine, I used the make up air vent and piped air into that location from the outside. I also piped in combustion air.
