A wood-fired hot tub made from a large storage container, an LP gas bottle, stainless steel tubing, polystyrene packing material, and some corrugated iron. That’s one bad-ass looking burner.
I’ve done this while camping, but a bit differently.
We dug a large hole into the ground, then lined it with a few tarps. The heater was a radiator made from copper pipe and a BBQ grill. It was placed into a fire, and two garden hoses connect to it, both running into the hot tub. A submersible pond pump is first used to draw water from a lake or ocean into the tub. It is then used to draw water from the tub, through the heater, and back to the tub.

I consider my VW bus the steel tent for camping, so it’s not like I’m hardcore! This seems a lot to pack in, however…..:)
