What Is DIY Outdoor Wood Furnace and what is its operation? An outdoor wood furnace operates by burning wood, typically logs or split wood, to generate heat for heating buildings or multiple structures. The wood is loaded into the furnace, ignited, and undergoes combustion, producing high temperatures. A heat exchanger within the furnace transfers the heat from the burning wood to a fluid, often water or a water-antifreeze mixture, circulating through pipes or tubing. This heated fluid is then pumped through underground pipes or a heat exchanger within the building's heating system, where it releases its heat, warming the indoor space through radiant floor heating, baseboard heaters, or forced-air systems. The cooled fluid returns to the outdoor furnace for reheating, maintaining a comfortable indoor temperature regulated by a thermostat or controller. Outdoor wood furnaces offer the advantage of using a renewable fuel source and keeping the mess and potential hazards of burning wood outside the living space, making them an efficient and environmentally friendly heating option.
