|The "Heet Deemun (Heat Demon)- concept and sketch by Derek "Deek" Diedricksen. A tiny, candle-based heater for very small spaces, tiny cabins, shacks, forts, and treehouses....|
Again, the idea can be tweaked, and potentially, you could get away without ANY welding by screwing a smaller diameter "flue" into the existing tap/inlet on the propane tank- although I don't know if that would draw enough and make for ample/adequate ventilation, which is the whole point here. Obviously, I'd still use a carbon monoxide detector in your tiny house, shack, or cabin when using something like this, and more importantly, before you cut into ANY propane tank (BOOM!!!) check out a few of the many tutorials and chat discussions on doing so that are everywhere online. Play it safe!
