Hi Pikachu, glad you got something from that. <img src="/images/boards/smilies/smile.gif" alt="" align="absMiddle" border="0" /> I just prefer kero or as the English say 'oil' to more explosive fuels like propane, etc. My own thing, I freely admit. But it is true that a kero stove takes very little fuel.<br /><br />Josephus, hi. I don't know much about vintage DuoTherm. and not sure why you had an issue with it. The type of kero stoves I've used are wick based, and the technology is beyond simple.<br /><br />Personally, I think diesel is more expensive, and also explosive, which I don't like. But that's just my own thang. Each to his own, neh? <br /><br />The most recent tent heating stove I've found that the army used in the mideast, according to this Surplus place, was a combo wood/oil heater. It has a barrel for wood heat which converts to oil (kero) by adding a burner. Nice and easy.<br /><br />Actually, I'm impressed by anyone building any kind of stove at all! LOL!! Now I'll have to go look up DuoTherm stoves.
