I'm intrigued by the idea, ever since I saw a Cowboy Hot Tub (Cowboy Hot Tub) and built a simple galvanized pipe coil that I would stick in a fire to heat water for camping or use to heat a 150 gallon rubber maid tub full of water.
How does the fire get air on these? I can't figure it out from the pictures on their website!
Thanks,
Amy
