What are the 10 Best Wood Furnaces?

Corporate History

Greenwood furnaces were originally produced by Greenwood Technologies, Inc. which was named after Greenwood Furnace State Park near Belleville, Pennsylvania. An iron-making plant once existed near where the park is now, and the plant was known for its furnace, which burned as hot as 3,000 degrees F. The plant covered the surrounding town with soot and ash. The owners of Greenwood Technologies, Inc. named their company after the plant as a reminder of the importance of environmental awareness.

In 2010, Greenwood Clean Energy aquired the brand, certain assets and intellectual property of Greenwood Technologies and now markets its products under the Greenwood brand.

Product Lines

Greenwood’s Frontier Series is an indoor wood gasification boiler with an efficiency of up to 89%. It is available in three models and features Greenwood’s Crossfire Combustion System, which modulates output to meet demand while leaving almost no smoke, creosote or ash. It can be installed in a radiant, baseboard or forced air heating system.

The Denali Series is a fully modulating indoor pellet boiler available in three models. It burns wood pellets, agro-pellets, and grains and is fully automated, meaning pellets are fed into the boiler and ash is removed through automated processes.

All Greenwood manufactured parts (excluding refractory and control boards) are covered by a 7-year limited warranty, pro-rated after the first year. All parts not manufactured by Greenwood, including insulation, electrical and control components are warranted by Greenwood for one year. Labor costs are not included in the warranty.
