Thermal siphoning rocket stove for an outdoor bathtub, though you could use it for an off grid hot water system. The advantage of the rocket stove is a clean and efficient burn. This system uses 5 metres of 20mm annealed copper pipe, and though I designed the rocket in a J configuration, it worked better as a batch box. There is a vortex generator at the base of the riser and basically I was able to heat 200 litres of cool water straight out of the tap to 67 degrees Celcius / 152.7 F in 1.5 hrs. Please let me know if you want the plans for this build, as I will make them available on my website if there is interest. www.littleaussierocketstoves.com Build and use at your own risk.
