This video is an educational animation showing the inner workings of a Zaug Stove. These stoves are unique because they use sticks and branches to generate large amounts of heat. The temperatures inside the stove, gets so hot that all the combustable gasses within the wood are burned off completely, leaving only steam as an exhaust byproduct. When combined with a thermal mass of clay or brick, the heat is captured and stored for hours inside the home, radiating heat slowly back in to the home. This means you can build a fire long enough to heat up your mass, then you can let the stove burn out and the mass will heat your home, shed, or greenhouse.
Comparing the exhaust of a conventional wood stove in full operation (left) to a Zaug Stove in full operation (right), the evidence is clear. The Zaug Stove burns much cleaner. The design of a Zaug allows for oxygen to mix with fire for a complete burn of gasses resulting in very little wasted fuel exhaust.
