Froling S3 Turbo Indoor Wood Gasification Boiler, High Efficiency EPA Certified Wood Boiler with Lambda Control: Click HERE for more information on Lambda controlled wood boilers.

The Fröling S3 Turbo 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 S3 Turbo has a 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. 

The combination of 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.

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.

The S3 Turbo 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.

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

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. 

The boiler is covered by a 20 year limited warranty.
