here's a similar concept (lost the diagram)X found! Zodi Fire Coil Water Heater Available Fall 2009 The Zodi Fire Coil delivers hot water with just a camp fire. Simply connect the Fire Coil to two stacked water jugs then place the coil in camp fire. Water flows from the elevated jug...

well I agree it's potentially a little dangerous... but remember, it's instant hot water, so the operating temperature must be determined while there's flow. I suppose, with some fine-engineering, a thermostatic pre-flow system would be viable. Camp showers (eg 12v) if I remember correctly can...

I agree, an insulated casing would be ideal - and safer! I was thinking - simple, cheap, even home-made. An insulated 'water-jacket' would be great: that means the coils could be included/incorporated into the casing possibly achieving maximum heat transfer potential. I have no idea which...

Thanks for replies. Of course there are gas instant water heaters, hundreds of makes, sizes, volume capacities... What I'm proposing is an apparatus that anyone with a gas cooker, or small fire, could inexpensively use, where no other hot water source is available. Also, maybe so simple a...

[see attached diagram]I've not yet tested this! Trying to find portable instant hot water systems on line, I thought of this: A thin copper tube coil cone that can be placed over a conventional gas cooker burner. The cold water source can be a tap(faucet), raised storage container, or a pump...
