Fröling S3 Turbo Wood Gasification Boiler

High Efficiency EPA Certified Wood Boiler with Lambda Control

Approved for 2020 EPA emission levels!

The Fröling S3 Turbo Wood Gasification Boiler uses Lambda controlled down draft wood gasification technology to achieve top of class performance.  The variable speed induced draft fan not only enables fast lighting, but also captures smoke during the lighting process and eliminates smoke leaks around doors. 

The Fröling S3 Turbo Wood Gasification Boiler is used in conjunction with thermal storage to maximize clean combustion, to simplify operation, and ensure long life.  All control and thermal monitoring functions for thermal storage are built in to the boiler control panel.

The boiler is covered by a 20 year limited warranty.

The built in heat exchanger cleaning system dramatically reduces or eliminates a need for hand brushing, which is an important component of continuous efficiency.  Ash from the heat exchanger is easily removed through a rear access door.

Cool touch: A meticulously designed and constructed insulation jacket complete with floor insulation and extra thick door insulation contains boiler heat during and between fires.

“Everything seems to be working well with the boiler. We are really enjoying it as a huge upgrade from our previous gasifier.  Love the starts and lack of smoke in boiler room. The shutdown controls are also awesome.”

The S3 Turbo has unique lighting door, further taking advantage of induced draft, which enables the fire to be ignited quickly and simply, even for occasional operators.  Add wood, light, close the doors, and walk away.  There is no sequence of switches or levers to worry about.

Menu driven controls provide full details of boiler operation and include thermal storage tank temperature. 

Lambda control and a variable speed fan enable the boiler to have variable output, which enables the boiler to more closely match heating needs.  Air controls precisely match burning conditions with motorized shutters.

Outdoor Wood Boilers or Wood Furnaces vs. Indoor Wood Boilers

Tarm Biomass sells indoor wood boilers.  Indoor wood boilers can be located in detached buildings outside of the primary heated space, but they are not weatherized like outdoor wood boilers or outdoor wood furnaces.  Indoor wood boilers generally provide better heating performance, as heat losses from the appliance and pipes go to the home rather than outdoors.  Customers who have switched from using outdoor wood boilers to indoor wood boilers have reported reducing wood consumption by half or more.   Due to problems with smoke from outdoor wood boilers and outdoor wood furnaces, they are banned in many areas where indoor wood boilers remain legal.  Some New York and Massachusetts  pay cash bounties when outdoor wood boilers are replaced by indoor wood boilers.  For more information about these programs, click here.
