Fred Lake : Usually, for compactness, The barrel exhausts down into the base where it turns at right angles to enter the Horizontal thermal mass!
Using the Rocket mass heater in a Greenhouse has problem areas to overcome, and this is a little out of my area!
1) Artificially high moisture content in the soil and in the air, combining with lye in the wood ashes deposited within the Barrel, Rocket core and in the thermal bench potentially causing the mortar and the horizontal stove pipe to degrade esp. when the thermal material is buried down in the green house floor
2) The high levels of moisture making the Cob Bench spongy, and causing it to sag .
3) The dragon that lives in your rocket needs frequent feedings of DRY Small Wood, Over 3-4 hrs to give you 20-24 hrs of thermal mass heated green house, while you are working in your green house!
The wood will need its own storage area outside the green house to keep it perfectly dry ! which means you will meet your self coming and going thru the outside door exactly when you are trying to conserve heat!
I have asked the 'powers that be' here at permies to create a Rocket stove in a Greenhouse Forum page so that like minded people can get together and figure how to deal with these issues !
Hopefully we will get that soon, hope this helps Pyro-maticly yours Allen L.
