The rocketmass heater

This is my start with a small Rocketmass heater  that I'm building in a 10x20 greenhouse. We are in south east Michigan and the winters can be harsh down right brutal (ya know with all the global warming and all)! My hopes are to be able to keep things growing and to keep the aquaponics system thriving and not going dormant .....

This is the main burn chamber and chimney in mortar ...

The barrel on the left will be fitted over the taller "chimney" part ... The smoke and gasses will then exit at the bottom and heat the mass that will become the bench ... 

The bench will cover about a 10x3 foot area of the floor and be about 2 foot high ....Hopefully this will be enough to keep it warm all winter .....

More to come soon
