[Stoves] Don't waste the heat, grow red wigglers and glorious greens

[Gerrie Baker]

Thanks for your input.  The boiler supplies a closed loop radiant floor 
Kytec pipe heat distribution system filled with food grade glychol.  A 
conveyor lifts wood waste into a hopper and three multistage augers 
transfer the biomass chips into the furnace where the fuel is 
concentrated and fans blow in air and the fire reaches high temperatures 
heating the steel plates and water circulating pipes.  It is inside the 
boiler chamber (second stage of the furnace) that large logs are 
converted to biochar when the air is shut off.  I had not thought about 
dunking it and given this set up currently this would be hot and 
difficult.  I am transitioning this property with the business to a 
multistakeholder cooperative and I am looking for members. G
