# Wood Gasification Boilers

Burn cleaner, waste less energy and extract more heat from the wood you burn.
All Fröling boilers use the gasification process. We'll help you compare models and design a system that works for you.

## Why Choose a Wood Gasification Boiler

### 1. Much Higher Efficiency

Gasification forces wood to burn in two stages:

1. Primary combustion:
  The wood is heated in a low-oxygen chamber, releasing combustible gases (carbon monoxide, methane, hydrogen, tar vapors).
2. Secondary combustion:
  Those gases are then burned at very high temperatures in a separate chamber with preheated air, producing almost complete combustion.

This leads to greater efficiency compared to traditional wood boilers and open wood stoves.

### 2. Cleaner Emissions

In a traditional wood stove or boiler, much of the visible smoke is actually unburned fuel—resulting in wasted energy and higher air pollution.
A wood gasification boiler reburns that smoke at high temperatures (often 1,800°F+), leaving mostly CO₂ and water vapor. This leads to extremely low particulate emissions, our boilers exceed the EPA Step 2 regulations.
Low emissions = better air quality and no complaints from neighbors.

### 3. Lower Fuel Costs Over Time

Compared to conventional wood boilers you get more heat per cord and will burn 30%-50% less wood. This saves you money if buying firewood, and saves labor if cutting it yourself. Also, dry hardwood yields even better results, meaning fewer storage needs.

### 4. Better Heat Storage & Comfort

Fröling boilers are paired with thermal storage tanks. You can fire the boiler once or twice a day, store the heat, and draw from the tank as needed, avoiding constant refueling. Produces steady indoor temperatures instead of the peaks and valleys with direct-burning stoves.

### 5. Longer Lifespan & Less Maintenance

Secondary combustion burns off creosote-producing vapors, so there’s less soot buildup in the chimney. Less creosote means lower chimney fire risk and less cleaning. Fröling Boilers can last 20 years or more when properly installed and maintained.

### 6. Flexibility in Fuel

Ideal moisture content is 15%-25% for the Fröling S3 Turbo indoor cordwood boiler. It can integrate with oil, gas or electric backup systems for seamless heating.

### 7. Environmental Benefits

They burn so completely that gasification boilers make carbon-neutral heating much more realistic. You’re releasing the CO₂ the tree absorbed while growing, without extra fossil fuel waste. Less particulate matter helps communities meet air quality goals.

## Bottom line:

Fröling wood gasification boilers are the high-performance standard of wood heating. Through advanced combustion engineering, they achieve cleaner burns, higher heat output, and far less wood waste than conventional boilers or stoves. While the initial investment is higher, these systems deliver long-term value through significant fuel savings, reduced maintenance, and reliable compliance with environmental regulations.
