How To Make A Cobb Rocket Stove Water Heater

This cobb rocket stove has a secret...it makes hot water. By adding a 3/8 inch copper coil to this mud-based rocket stove, I am able to circulate water using a thermal siphon to heat a bucket of water. Part 2 of the video will be the creation of an outdoor shower. The 5 gallon bucket got pretty fast...hotter than a shower would need to be. In this video I make the stove with a mixture of sand, clay and straw.
