Friends and Enthusiasts,

At this time Zaug Stoves is not manufacturing stoves until we can obtain the proper UL Listing and EPA certification. We are currently seeking investors to make that happen. If you would like to contribute, please visit: Seeking Funding- Phase 1  Updated 11/11/2017

Zaug Stoves Co., is the first of its kind as a rocket mass heater manufacturer and distributor of the Zaug Stove; A super-efficient wood stove, which uses a combination of technologies known on the internet as rocket mass heater technology and masonry heater technology.

Wood Stoves Lose Heat, Zaug Stoves Use Heat

The Zaug Stove is designed to be a combination of a rocket stove and a masonry heater. The theory behind a masonry heater is that it has the ability to store a large amount of heat within its composition, usually made of rock, cob or brick. This means that you can tend a fire to heat the masonry unit, and after the fire goes out, the masonry unit will continue to give off heat. The heat then slowly radiates into your house for the next 18 to 24 hours, eliminating the need to keep feeding the stove.

The principle of Rocket Mass Heater Technology

Standard Zaug Feed Tube
Air is immediately drawn in to the system when a flame is lit.

Once a fire is lit in the burn chamber air is immediately drawn in to the system through the feed tube. As wood continues to burn in the burn chamber, more air rushes in from the feed tube to mix with the fire and hot gasses, reaching temps capable of burning the gasses completely. The air becomes super heated and expands in the combustion chamber forcing the air up through the system, until the air reaches the outer chamber where it cools down and contracts. The hotter the fire burns, the greater the amount of oxygen will draw in to the burn chamber. This expansion/contraction creates enough force within the unit, to push hot air through the exhaust line at incredible distances, before needing to go up and out. The result is a cleaner more efficient burning stove which uses less fuel to produce great amounts of heat. Combine the stove with a horizontal exhaust system that will heat a masonry unit, and you have a masonry heater that will give off hours of heat from burning sticks and branches, while emitting almost zero pollutants. It’s a new way to look at using wood for a heat source. The Zaug uses less wood, but captures and efficiently utilizes more of the heat produced from the smaller fire.

Heating a Thermal Mass

The benefit of having an exhaust line running horizontally, is that it offers more surface area of heating power. Encasing the exhaust with clay or rock will extract the heat from the exhaust pipe, and store it in the masonry unit or Thermal Mass, giving off heat slowly over the next 18-24 hours. This type of heating system requires only a 2-4 hour fire in the stove, to provide many hours of heating from the masonry mass.  In greenhouses, the masonry unit could also be a raised grow bed of soil, or even directly in the soil under the greenhouse.






Learn-More-Button-BlueUsing a Zaug Stove helps to reduce carbon emissions from wood burning, and reduces the carbon footprint on the planet; it also helps to reduce deforestation, and creates jobs in our local community. With international sales increasing, we are poised to bring this new stove and technology to people across the globe, who enjoy sovereignty and appreciate sustainable products.
