Hi my name is Shiloh. I have a few questions. We want to build a thermal mass rocket stove for our aquaponic greenhouse. It is 72x30 ft and has media beds that run 58ft long. Our desire in to put the chimney/ thermal mass bench under the media beds. The trick is there is not a lot of room under there. We have chosen to use 4 inch double insulated pipe because of space limitations and can only put 3-4 inches of cob on top of the channel. The channel is made of cinder blocks and filled with gravel, then the cob. This will leave about 3 inches before reaching the bottom of the media beds. My question is Is that enough space and mass to not melt my beds. Another concern is am I going to need a S formation for the exsaust coming from the barrel to cool down the air flow before it goes under the beds.
thanks for any help.
