I am currently building myself a Rocket Heater. Based off of the rocket stove. It will be made up of 3 LP tanks welded together and an internal chimney of 4 x 3 Rectangle tube steel. If all goes well I should have it up and running in a month or so. Just waiting on my buddy to teach me how to weld. Once I have it up and working I will let you know how it is doing. I was drawn to this style as it uses very little wood and produces large amounts of heat.
