Most wood fired units to boil down maple sap to maple syrup are low tech and appear very inefficient. Basically, there is a pile of wood under the pan, and that's your heat source. I can't image they get more than 30-40% efficiency.
Is there a way to rig up a wood gassifier to boil maple sap? I am thinking running a hydronic system with oil instead of water. Run at ~275F. Pipe the hot oil through copper tubing coiled in pots to boil the syrup.
Has anyone ever considered this?
