After seeing many YouTube videos on these Rocket Heaters I decided I wanted to build one in my greenhouse. I had too many grow beds for my water/fish ratio so I took one of the larger ones out to made room and proceeded to build a test stove...
Base laid using leftover supports from the former grow beds...
Basic structure of a standard 20 fire brick J tube rocket. Riser made from two pieces of black stove pipe with vermiculite for insulation.
( I know this will have to be replaced soon for a more permanent one)
I didn't get any more pics of the temporary one but I topped the riser off with a small metal barrel and sort of sealed everything by piling sand and pea gravel around it with a little cob around the bottom of the riser and the vent.
It smoked a little probably because it wasn't sealed good but it burned great and had a good rocket action. The barrel got up to 500 degrees while the exhaust pipe never got too hot to touch.
After deciding this would work great I tore the temp one apart and proceeded to build it right.
This is the almost finished product and it works great.
I still have to get a few more bricks and some sand and cob to finish it off but it works great!
I have only burned it once but with only a couple small armfuls of cut up branches the mass was all warm to the touch and the greenhouse was at about 60 while the outside temp was 35. Now I need to figure out a water heater system to go along with it....
That is for another day..
Matthew 11:28-30
Come unto me, all ye that labour and are heavy laden, and I will give you rest.Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.

For my yoke is easy, and my burden is light.
