Heating with oil or propane?

The Fröling S3 Turbo is a high-efficiency indoor cordwood boiler designed for modern hydronic heating systems. Manufactured by Fröling in Austria since the 1960s, the S3 Turbo combines advanced wood gasification technology, low emissions, and thermal storage integration for clean, efficient, and comfortable wood heating.

Unlike traditional outdoor wood boilers, the S3 Turbo is designed to burn hot and clean while storing excess heat in insulated thermal storage tanks for consistent system performance and improved efficiency.

Froling Wood Boilers works with homeowners and local installers throughout the U.S. to help design and commission complete cordwood boiler systems.

Heating your home with oil or propane shouldn’t feel like a gamble every winter.

Prices swing. Supply changes. And you’re left hoping this isn’t the year your heating bill spikes.

There’s a more predictable way to heat your home.

At Froling Wood Boilers, we provide high-efficiency wood heating systems for homeowners who want control over their heating costs—featuring the Froling S3 Turbo (indoor cordwood boiler) and the Froling PE1 (automatic wood pellet boiler).

Both systems are manufactured by Fröling, an Austrian company that has been building advanced biomass boilers since the 1960s.

✔️ Burn cordwood or pellets—fuels you can plan for
✔️ Stable, long-term heating costs
✔️ Clean, efficient, and easy-to-operate systems
✔️ Proven performance in real-world conditions

We work directly with your local installer to design the system properly and support commissioning—so you get a setup that performs the way it’s supposed to from day one.

Instead of reacting to fuel price spikes, you can take control of how you heat your home.

If you’re tired of the ups and downs of fossil fuel pricing, it might be time to consider a better option.

Modern cordwood heating might not look like what you remember.

Here’s a recently installed Froling S3 Turbo paired with properly sized thermal storage in a New England home.

The S3 is an indoor cordwood gasification boiler designed to operate in controlled, high-efficiency burn cycles. Thermal storage captures that heat and delivers it to the home as needed — just like oil or propane.

Using lambda-controlled combustion, the boiler continuously adjusts airflow based on flue gas oxygen levels, maintaining clean and stable combustion.

The result:
• Clean gasification burn
• Stable high efficiency performance
• Extremely low emissions
• Real-world hydronic comfort

Modern cordwood heating is engineered — not improvised.

If you’re heating with oil or propane and have access to firewood, it may be worth understanding how much the technology has evolved.

Installed: Froling S3 Turbo 50 Cordwood Boiler
Application: Residential Heating
Fuel: Split Cordwood

This project was a true plug-and-play retrofit, replacing a 20-year-old Tarm boiler with a Froling S3 Turbo 50.

Froling Energy supplied the system directly to the homeowner, who partnered with their preferred installer to complete the installation.

The homeowner retained their existing 1,000-gallon atmospheric thermal storage tank, allowing modern lambda-controlled combustion technology to integrate seamlessly into an already proven hydronic system.

The S3 Turbo is engineered for homeowners who want high-efficiency cordwood heating without constant attention. With intelligent combustion control and integrated safety management, it delivers clean, consistent performance even during extended cold-weather operation.

For homeowners upgrading from older wood boilers, Froling represents the evolution of cordwood heating — cleaner combustion, smarter controls, and performance legacy systems simply weren’t built to deliver.
