Gasification has been around for decades and is the most efficient way to heat your home. A combination of high temperatures, dry wood, and limited air, create exhaust gases inside the furnace firebox. These exhaust gases are forced downward through the wood fire ash bed into the secondary combustion chamber which burns at temperatures up to 2,300°F with a 99% combustion, this process ignites gasses removing any smoke while the unit is operational. This heat is then transferred to the heat exchanger tubes which are strategically placed in the water reservoir to transfer heat to the water, assisting in achieving high efficiency and low emissions.
The unburned gases exit the stainless steel flue exhaust at temperatures as low as 300°F. You will notice that our Pristine Gasification Series of outdoor wood furnaces is virtually smokeless, this is due to our Negative Pressure Gasification process. The less smoke you see, the better the efficiency.
