ATMOS DC30GSP wood and pellet boiler – powerful combination boiler with 29.8 kW
The ATMOS DC30GSP is a powerful combination boiler for burning firewood and wood pellets. The boiler combines the efficiency of a modern wood gasification boiler with the convenience of an automatic pellet burner. This allows both fuels to be used flexibly.
With a wood output of 29.8 kW the biomass boiler is particularly suitable for larger single-family homes, multi-family homes, or buildings with higher heat demand. The combination of wood and pellet operation enables reliable and convenient heating.
Highlights and benefits
- ⭐ Combination boiler for firewood and wood pellets in one heating system
- ⭐ Heating output up to 29.8 kW for buildings with higher heat demand
- ⭐ Automatic pellet operation possible after the wood has burned out
- ⭐ Efficiency up to over 92% for efficient fuel utilization
- ⭐ Boiler class 5 according to EN 303-5 for modern biomass heating systems
Areas of application & target group
The ATMOS DC30GSP is suitable for various applications in residential and commercial buildings:
- larger single-family homes
- multi-family homes
- renovation of existing heating systems
- new buildings with biomass heating
- heating systems with buffer storage
By combining firewood and pellets, the boiler offers high flexibility. Wood can be added manually, while pellets are fed automatically.
Everyday benefits
The combination boiler enables convenient operation with two fuels. In wood operation, the boiler works as a powerful wood gasification boiler. Once the wood has completely burned out, the pellet burner can start automatically and continue heating operation.
This ensures that heat supply is maintained even when no wood is added. This increases convenience and reduces the effort required for daily heating operation.
Technology & equipment
The ATMOS DC30GSP features a robust steel construction and a ceramic combustion chamber. Several thermostats and control components ensure safe and efficient operation.
- Boiler thermostat for power regulation
- Flue gas thermostat for controlling the induced draft fan
- Safety thermostat (STB) for overheating protection
- Servo flap for automatic air regulation
- Preparation for electronic heating control
Air supply and combustion are automatically adapted to the respective fuel, ensuring stable and efficient heating operation.
Efficiency & environment
In wood operation, the boiler achieves an efficiency of approximately 91.4%. In pellet operation, the efficiency is around 92.8%. This ensures particularly efficient use of the fuel used.
The ATMOS DC30GSP meets the requirements of boiler class 5 according to EN 303-5 and complies with modern emission standards for biomass heating systems.
Compatibility & system integration
For optimal operation, the combination boiler is usually installed with a buffer tank. This allows the generated heat to be stored and distributed evenly throughout the heating system.
The ATMOS DC30GSP can be integrated into various heating systems:
- Buffer tank
- Radiator systems
- Underfloor heating
- Domestic hot water preparation
