I have been burning wood, no oil, for a week now. My thanks to the many great tips on this forum that I have studied for the past year, and to FlyingCow for letting me view his setup. I have attached a few pictures to show the results of a couple months of hard work constructing a furnace room in the woodshed, putting together the heat storage tank, and insulating pipes. The American Solartechnics tank is well insulated and has very little heat loss. Daigle Oil Co. did the heavy duty heating and plumbing work.
