Enjoy Modern Wood Heating
Central home heating with modern wood gasification
The Greenwood® Frontier Series is a modern, wood gasification boiler that burns fuel so completely it leaves almost no smoke, creosote or ash. When installed in a radiant, baseboard, radiator or forced-air heating system, the boiler can reduce heating bills by 70 percent.
Designed with you in mind, there is no need to split wood; high temperatures in the firebox eliminate build-up and reduce ash to amounts that require attention just once a month.
The Greenwood Frontier Series meets strict EPA and Washington State air quality standards. The Greenwood Frontier has also received an A+ European Ecodesign Rating -- the new gold-standard.
Open the door of a Greenwood® and witness the radiant transformation of wood to pure energy – an experience so mesmerizing; we had to give it a name.
With a Greenwood, you can take control of your heating bill and save up to 70% on your heating costs while turning up your thermostat.
The Greenwood Frontier Series redefines the meaning of high-efficiency heating – Converting up to 88% of the energy in wood fuel to usable heat in your home.
Each Greenwood appliance is certified for indoor operation by an independent agency to ETL, CSA and European standards.
