Homemade boilers - ArboristSite.com. MARC ASHLEY IS BEATING THE HIGH COST OF ENERGY. Marcus Ashley's solution to the skyrocketing cost of home heating is the “overgrown doghouse with a smokestack” that sits in his backyard.
That doghouse is really a scrap outdoor wood-burning furnace that provides Marcus and his wife with all the hot water they can use. It keeps their Massachusetts home at a constant and comfortable 68° F, and warms a greenhouse that's attached to the residence. “Everybody told me this setup wouldn't work the way I thought it would,“ grins Marcus, “and maybe they were right. After all, on really cold days I do have to go out once in a while and throw in an extra stick of wood.
But I guess it works well enough.” Homemade woodburning boiler. I shudder everytime I hear of someone trying to make a steam boiler or operate one without any training.
Boiler explosions level buildings! Stick with an open system - PLEASE! Great Northern Camp Stove, Military Surplus, Major Surplus at Sportsman's Guide.
