GN2000
The GARN® GN2000 Wood Heating System (WHS) is a wood boiler that combines wood gasification and thermal storage into a single unit to deliver clean, smoke-free and creosote-free heat. Capable of heating up to 10,000 square feet and delivering up to 200,000 BTUs per hour, the 2000 WHS comes packed with decades of engineering excellence to heat even the coldest, most remote environments.
Serving the World with Clean Wood Heat™
Heating your building with a GARN® 2000 WHS starts with batch-burning a load of cordwood in the unit’s 17.4-cubic-feet firebox. As the wood burns, it heats 1,830 gallons of water stored in the unit’s tank, transferring nearly 1.2 million BTUs’ worth of heat energy into the water. Finally, the water is delivered via radiant floor/ceiling, hot-water baseboard, or forced-air heating systems to warm the property.
Ideal for commercial, industrial, farm, greenhouse, and shop applications, GARN® 2000 WHS units may be used individually or in tandem to meet your heating requirements. They can easily be installed in existing buildings or inside a lean-to addition. An Electrical Heating Package is also available which allows users to take advantage of off-peak hours or discounted rate programs.
Each GARN® is built with pride by American workers and certified to UL and CSA standards for use in the United States and Canada*.
*GARN® Wood Heating Systems are approved for commercial applications only in the United States and all applications in Canada.
