Here's the start of what i will be building this winter. My central boiler is old, tired, and needs to be retired! I am dealing with heating a 5100 sft house which once was a school. the majority of the house is made of cinder blocks and has 13 ft tall ceillings. It definatly was not created with the intent of being effecent! It has a nice cold slab the entire 5100 sft of it. With all this being said my centrsl boiler saved me about $5-800 dollars per month for the heat and hot water. However i fill it twice a day and it is real fill ups!Th CB takes a 5' log and it is a hugry beast. I ve been starting to look at different gasification models and realized that i wanted lots of storage not 50 gallons of water like the majority of the the gasification boilers out there. I soon realized that i will be building this one myself. Having welded/repaired half a dozen wood boilers for friends and family has given me different ideas of how i want this to be built.. for now heres a pic of the tank that were starting out with.
