Residential Biomass & Wood Furnaces

Recognized as the leader in renewable heating appliances, Greenwood's wood heating systems' patented designs improve combustion and thermal efficiency, which enables cleaner operation and delivers more energy to your home. That means less wood, fewer emissions, and a warmer home for each dollar spent on fuel. Greenwood systems:

• Can reduce heating bills by 70%
• Operate virtually smoke and creosote free
• Leave little ash, reducing frequency of cleaning
• Consume 50% less wood than traditional outdoor wood furnaces
• Comply with the EPA Orange Tag program

Each Greenwood system also ties to most existing heating systems, including forced air, hot water baseboard, radiant, in-floor, and boiler systems. Controlled from the thermostat in your home, Greenwood solutions deliver the heat you expect at a fraction of the cost.

Aspen Series Outdoor Wood Furnace

The Aspen Series of outdoor wood furnaces are designed for residential or light commercial use. Often used as a replacement for older, less efficient outdoor wood boilers, the Aspen Series provides clean efficient operation using medium and small cord wood; because of its high efficiency, it produces little ash, so it requires infrequent cleaning.

Greenwood Furnace Series

The Greenwood Furnace indoor wood boilers redefine the concept of wood boilers. Operating at white-hot temperatures within a single combustion chamber, these units burn the wood completely leaving little or no particulate to create smoke, creosote or ash. Unlike most units, the Greenwood Furnace performs best when burning large un-split cordwood rounds and store energy in the cast refractory and the unburned log.

Choosing the Right Greenwood

Here's why more people are buying a Greenwood high-efficiency system:

• Clean Burning. Greenwood furnaces burn their fuel completely, leaving few particles to create smoke, creosote or ash.
• Energy Efficient. Greenwood boilers approach 85 percent thermal efficiency. This means most of the heat released by burning wood is captured to heat your home.
• Economical. Greenwood boilers reduce your overall heating costs. A study by the Canadian government found that wood fuel can cut home heating costs by up to 70 percent.
• Certified Safe. Greenwood biomass and wood boilers meet strict UL and CSA standards for INDOOR operation. They are as safe to operate as a home water heater.
• Environmentally Sound. Greenwood furnaces release no incremental emissions into the environment. Unlike fossil fuels, biomass fuels, such as wood, are a home grown and a fully renewable source of energy.
• Easy Maintenance. Since Greenwood hydronic furnaces are clean burning, they do not need to be cleaned as often as wood stoves or inefficient outdoor wood boilers.
• Reliable Design. Wood furnaces built with Greenwood's proven design have been in operation for many years and continue to provide reliable, low-cost home heating for their owners.
• Superior Quality. Greenwood wood gasification boilers are manufactured in a state-of-the-art facility where skilled craftsman follow strict quality assurance procedures. Our furnaces are made with top-quality components and materials, including our durable cast-ceramic firebox.
