Each Zaug is custom made to order. There are 45 individual pieces of steel welded together to complete one unit. The 12 gauge cylinder and 2″ trim are rolled and welded as well. Once the welding is complete, the surfaces are cleaned, washed in lacquer thinner, and prepared for paint. A coat of Thurmalox primer and two coats of Thurmalox paint is applied for a smooth finish. The result is a beautiful Zaug stove for heating and cooking.
Fabrication takes approximately 28 days from start to finish.
Stove weight is 275 lbs. Shipping weight is 435 lbs (shipping crate weighs 160 lbs.) and is class 85. We ship from Yelm, WA 98597. We use FreightQuote.com for our shipping needs.
The Zaug Stove operates best with sticks and branches but can also handle 5” rounds up to 24” long. The fire eats a hopper of sticks and branches in about 30 minutes. A solid round will burn in about an hour.
The cooktop of the stove can be easily removed for access to the interior, for quick cleaning. There is an easy-access ash pit, resting in the pedestal, for removing burned ash. The air-intake chamber over the feed tube, is dampened down and can be completely closed off with the bi-fold hinged door on the top of the intake.
The most beneficial way to use a Zaug stove, is to add a thermal mass around the stove exhaust to capture and store heat from the exhaust. The easiest way to do this is to make a bench or hearth, out of cob or clay, but brick or masonry can be used as well.
For more information on how to build a thermal mass, research Rocket Mass Heaters on the internet.
In our tests, the Zaug burns about 1 cubic foot of wood in 4 hours.
There’s 128 cu. ft. in a cord of wood, so that would last 128 days of warmth. A four-hour fire is enough to heat up your mass and nearly heat you out of your home.
For heating greenhouses, the exhaust duct can be installed in the ground, so that it runs approximately 6 inches underground, to heat the soil. The soil will act as a thermal mass and retain heat for several hours. If you have an aquaponics system, you may even consider wrapping a coil around the Zaug exhaust to heat the water in your system. The exhaust duct temperature is approximately 225 degrees. Extreme care would have to be taken to avoid over-heating the fish.
We have tested our exhaust up to 47 feet before we change the direction to vertical. We have found that adding a section at the end of the run vertically, dramatically increases the draw in the unit. This is a new technology and we will be discovering better and more efficient ways to use this stove in the future.
For an additional cost, we can install 3-panes of fireproof glass on the feed tube. This makes viewing the fire possible.
We also offer placement of the exhaust port anywhere on a 90 degree swivel, left or right. When designing your system, tell us where you want the exhaust to go and we can accommodate your system. For instance, if your stove sits in a corner, and your thermal mass runs along a wall at a 45 degree angle, we can place the exhaust port to exit the stove right where your mass starts.
We are in the process of certifying the Zaug Stove with the proper EPA and UL regulations; However, at this time, the Zaug Stove is not recognized as a conventional wood burning stove by the EPA. Unfortunately, the EPA does not have a test for this new type of technology. It may be some time before an independent research and development team can design a test for our stove. Thank you.
