Frontier Series Wood Boiler

The Reinvention of the Wood Boiler

The all-new Greenwood Frontier Series is the most capable wood boiler ever. Not only does it deliver best-in-class performance, each Frontier Series comes packed with features you won't find on any other wood boiler on the market:

  • For greater performance and fuel flexibility, there is the CrossFire Combustion™ System.
  • The built-in Load Conditioner, removes the complexity of connecting the boiler with the existing heating system while shielding the boiler from the home's hydronic setup, ensuring years of optimal performance.
  • The Greenwood® Boiler Management System keeps the appliance operating at peak performance, even during the low-demand days of the spring and fall, and provides unparalleled insight for your service technician.
  • Engaging SmokeGuard™ and opening the load door imparts a sense of quality and satisfaction unmatched by any other wood boiler.

You asked us to reinvent the wood boiler – we bring you the Frontier Series – you won’t look at other wood boilers the same again.

But don't take our word for it, watch a short video of one in operation and then talk to your local Authorized Greenwood dealer and set up an appointment to see one in person.
