Fröling S3 Turbo Wood Gasification Boiler

 

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.

What Is the Fröling S3 Turbo Wood Boiler?

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.

“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.”

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. 

To learn more, check out our video explaining how to start a Fröling wood boiler.

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.

Outdoor Wood Boilers or Wood Furnaces vs. Indoor Wood Boilers

Let's break down the differences between outdoor wood boilers, also known as wood furnaces, and indoor wood boilers.

Outdoor Wood Boilers

As their name suggests, outdoor wood boilers are for use outdoors. Their placement means they don't take up space in your home. They typically have weatherization to help them withstand the elements.

However, outdoor wood boilers have significant disadvantages. Because of problems with smoke from outdoor boilers and outdoor wood furnaces, they are banned or are the subject of special regulations in many areas where indoor gasification boilers remain legal.  Heat losses from outdoor boilers and pipes to the house may reduce efficiency.   

Indoor Wood Boilers

Indoor wood boilers are ideal for indoor home heating. They can be located in detached buildings outside of the primary heated space, but they are not weatherized like outdoor boilers or outdoor wood furnaces.

Tarm Biomass sells indoor wood boilers — keep in mind that the Fröling S3 Turbo is an indoor wood boiler, not a furnace. Even though the S3 Turbo is a boiler, it can easily heat forced hot air, with automatic backup from an existing oil or gas hot air furnace.

indoor gasification boilers

The great advantage of indoor boilers is that they 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 boilers to indoor gasification boilers have reported reducing wood consumption by half or more. For a more detailed comparison, visit our resource page

The Fröling S3 Turbo is an indoor, wood gasification boiler. It uses an engineered combustion chamber with limited oxygen and high heat to turn wood into useable energy. The high heat vaporizes the fuel and sends smoke into a secondary chamber, which uses the oxygen to create an intensely hot fire.

Gasification differs from combustion — the process in a traditional wood stove — because of the minimal amounts of oxygen it uses. Gasification systems also use a multi-stage downdraft process that lets you control the air-to-fuel ratio, optimizing efficiency and clean burning.

If you purchase a Fröling S3 Turbo, you can expect to gain all the efficiency and heating performance advantages of indoor wood boilers, along with the high-quality design and performance unique to the S3 Turbo.
