Fröling S3 Turbo Wood Gasification Boiler

Contact Us Today

The Fröling S3 Turbo wood boiler sets the benchmark for wood burning. With advanced combustion controls and innovative features like a lighting door, a built-in smoke hood, and one-step operation, the S3 makes wood-burning easier, safer, cleaner, quieter, and more efficient. Fröling wood boilers also look great. More importantly, they are workhorses, which means less time for maintenance and low operating costs.

Perhaps best of all, the Fröling S3 Turbo is approved for 2020 EPA emissions levels. Using this boiler will typically reduce the carbon footprint of your home by about 75% compared to homes using oil and gas.

Fröling Boilers

The Fröling S3 Turbo wood boiler is a firewood boiler that blends superior technology with a competitive price point. This high-efficiency, EPA-certified wood boiler uses lambda-controlled downdraft wood gasification technology to achieve top-of-class performance. The lambda controls automatically monitor excess oxygen and adjust primary and secondary combustion air, optimizing combustion.

What Makes the Fröling S3 Turbo Special?

The Fröling S3 Turbo wood boiler has a high-quality variable-speed induced draft fan that enables fast lighting and captures smoke during the lighting process, while also eliminating smoke leaks around doors. It allows for output control and safety during operation.

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

Here are some other benefits that set the Fröling S3 Turbo apart from its competitors:

• State-of-the-art combustion chamber: The Fröling S3 Turbo's proprietary, long-lasting, high-temperature, and turbulent combustion chamber provides superior combustion values.
• Lighting door: The unique lighting door makes ignition simple.
• Smoke Extraction: The built-in smoke hood enables smoke-free reloading.
• Built-in heat exchanger cleaning system: This 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.

The Fröling S3 Turbo is covered by a 20-year limited warranty.

How to Operate the Fröling S3 Turbo Wood Boiler

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.

Once you've started the boiler, 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 allows the boiler to more closely match heating needs. Air controls precisely match burning conditions with motorized shutters.
