Application Area & Target Audience
The ATMOS DC22GSE is a manually fed wood gasification boiler for efficient firewood heating systems.
Typical application areas:
- Heating systems in single-family homes
- Renovation of existing wood heating systems
- New builds with renewable heating technology
- Heating systems with buffer storage tanks
- Heating systems with radiators or underfloor heating
The boiler is designed for use in modern heating systems and should be installed by a qualified HVAC specialist.
Advantages in Everyday Use
Wood gasification boilers utilize the energy of the fuel particularly efficiently. In the ATMOS DC22GSE, the wood is first gasified and then completely combusted at high temperatures.
This technology enables:
- high energy utilization of the fuel
- reduced emissions
- consistent heat output
- economical heating operation
The generous combustion chamber allows for convenient refilling of firewood and supports longer heating intervals.
Technology & Equipment
The wood gasification boiler features a forced-draft fan to support the combustion process and stabilize the chimney draft.
The most important technical components include:
- Forced-draft fan
- Boiler thermostat
- Safety thermostat (STB)
- Flue gas thermostat
- Belimo actuator
- Thermal discharge safety device
Dry firewood with a moisture content of approximately 12–20 % is used as fuel.
Efficiency & Environment
Through wood gasification technology, the ATMOS DC22GSE achieves high energy efficiency while simultaneously reducing emissions.
- Energy Efficiency Class: A+
- Boiler efficiency: up to 91.8 %
- Complies with BImSchV Stage II
This makes the boiler suitable for modern heating systems with renewable fuels.
Compatibility & System Integration
Wood gasification boilers are typically combined with buffer storage tanks to efficiently store the generated heat and distribute it within the heating system.
Typical combinations:
- Buffer storage tanks
- Return temperature elevation
- Radiator heating
- Underfloor heating
- Thermal solar systems
