backpacking sauna how to heat it without using hot rocks, ie perhaps with a portable steam generator or boiler ?
i am building a back packing sauna which is essentialy a old two man tent converted. my problem is the heat source for the steam.tradionally people would heat rocks in an open fire. this i feel is time consuming building a fire and then heating rocks for 2 hours or so. i am now thinking of trying to generate steam direct from a wood gas stove and piping it in to the tent anyone with ideas or sugestions please post here. whatever i use needs to be suitable for back packing.
