Perhaps you may have a hint about this pair of questions (who to ask about them, etc. Also i'm sure Heat Tools would have a reply). At least i'm hoping it's no trade secret:
Is there contact with the flame (soot)?What's the vest way to use butane in a radiative heat source? What about the THV for that matter? Etc.
Would it be exagerated to imagine a heat-pipe filled with some oil, transporting heat while leaving behind all potential contaminants simply because those can't pass the barrier in between. It would most likely require careful insulation... I'm not sure i'd want wood in the air/vapour path at such temperatures though!
I really think we've beat this to death.
There is a solid SS tube that runs from one side to the other. The fire is outside it, the air we draw in inside it. The exact same system (called a 'fire box' in the trade) is used in home heaters where the danger is real. That danger is CO poisoning, noting to do with normal combustion of the gas.
Dangers from 'Butane combustion products' are, IMO, imaginary. There is zero evidence. Zero. Raw Butane itself is pretty benign as well, look it up.
I suggest you actually get one and see before getting more upset about it. It's not broken, IMO, it doesn't need fixing.
