So far I've tried different lay outs for a rocket water heater. I tried heating a old hot water tank but even with a pressure relief valve I didn't feel it safe. Wood is not easy to keep at a set temp burn. So I'm using copper tubing to catch the heat.
I wanted to do a little cooking when fired the rocket. I'm cobbing, mudding, insulating the barrels in. All very wet and not done. I hope to have it, so the short barrel gets hot enough to make flat breads (pancakes). I have my doubts that will happen.
