ATMOS DC30GSP Wood and Pellet Boiler – High-Performance Combination Boiler with 29.8 kW

The ATMOS DC30GSP is a high-performance combination boiler for burning firewood and wood pellets. The heating 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, this biomass boiler is particularly suitable for larger single-family homes, multi-family houses, or buildings with higher heat demand. The combination of wood and pellet operation enables reliable and comfortable heating.

Highlights and Advantages

⭐ 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 of over 92 % for efficient fuel utilization

⭐ Boiler class 5 according to EN 303-5 for modern biomass heating systems

Application Area & Target Audience

The ATMOS DC30GSP is suitable for various applications in residential and building sectors:

larger single-family homes

multi-family houses

renovation of existing heating systems

new builds with biomass heating

heating systems with buffer storage

By combining firewood and pellets, the heating boiler offers high flexibility. Wood can be added manually, while pellets are fed automatically.

Advantages in Everyday Use

The combination boiler enables comfortable operation with two fuels. In wood mode, the boiler operates as a powerful wood gasification boiler. Once the wood has completely burned out, the pellet burner can start automatically and continue the heating operation.

This ensures the heat supply is maintained even when no wood is added. This increases comfort and reduces the daily operational effort.

Technology & Features

The ATMOS DC30GSP features a robust steel construction and a ceramic combustion chamber. Multiple thermostats and control components ensure safe and efficient operation.

Boiler thermostat for output 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

The air supply and combustion are automatically adjusted to the respective fuel, ensuring stable and efficient heating operation.

Efficiency & Environment

The heating boiler achieves an efficiency of approximately 91.4 % in wood mode. In pellet mode, the efficiency is around 92.8 %. This results in particularly efficient use of the fuel.

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. :contentReference[oaicite:1]{index=1}

Compatibility & System Integration

For optimal operation, the combination boiler is typically installed with a buffer storage tank. This allows the generated heat to be stored and distributed evenly within the heating system.

The ATMOS DC30GSP can be integrated into various heating systems:

Buffer storage

Radiator systems

Underfloor heating

Domestic hot water preparation
