If we hadn't just put the greenhouse for the winter in the space where our "hot springs" are supposed to go, I'd start digging tomorrow!
My vision is to have the coil at ground level and build a solar oven around it for preheating during the day. Then at night we start a fire when we want to use it.
Don't know what to use for the coil though. Just bought more 3/8" copper yesterday for the solar water heater in the greenhouse, not cheap,

It was merely an arrangement where a pipe was connected to the bottom of the tub and run out a ways from the tub. At that point the pipe was formed into an ascending coil and then went back to the top of the tub. Some sort of stove with a fire was lit below the coil in the pipe. The cold water came from the bottom of the tub to the coil and the heated water left the top of the coil by convection, making its way back to the top of the tub. Not very fancy, but they said it worked quite well. (This was in India, in the Himalaya mountains; a sister city to Simla which is being featured currently on the TV show "IRT Most Dangerous Roads.")
