My RMH is a real water heater. My lower heavy duty barrel also has the top removed. Resting on that is a regular 55gal barrel filled with water. When the RMH burns the internal riser exhausts below the bottom of the upper water barrel. The smaller bung at the top is loose to relieve any pressure. Facts: this is a 6 inch cast refractory RMH that probably reaches 1500f-2000f BEFORE the riser reaches the bottom of the water barrel, and the heat differential between the riser temp and the water barrel surface supercharges the draft adding to the pump action of the RMH. All other RMH characteristics occur- low external temps, clear exhaust, good fuel efficiency etc. plus tapping into the 200f water on top to heat anything should be easy. Also the burn chamber temp is 1500f-2000f while the final exhaust temp as it leaves is never above 80f.(amazing btu recovery). This getup has survived a 7.2 earthquake. I sent Erica a set of pics if you want to see...hope she got them. May the revolution continue! Mark H.
New guy here. Great info thanks for posting, i was looking to do something almost exactly as you describe.
