Application Area & Target Group
The ATMOS DC22GSE is a manually fed wood gasification boiler for efficient log wood heating systems.
Typical application areas:
- Heating systems in single-family homes
- Renovation of existing wood heating systems
- New buildings with renewable heating technology
- Heating systems with buffer 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 heating and sanitary contractor.
Everyday benefits
Wood gasification boilers use the energy of the fuel particularly efficiently. In the ATMOS DC22GSE, the wood is first gasified and then completely burned at high temperatures.
This technology enables:
- high energy utilization of the fuel
- reduced emissions
- uniform heat output
- economical heating operation
The generous combustion chamber allows for comfortable refilling of firewood and supports longer heating intervals.
Technology & Equipment
The wood gasification boiler features an induced draft fan to support the combustion process and stabilize the chimney draft.
The key technical components include:
- Induced draft fan
- Boiler thermostat
- Safety thermostat (STB)
- Flue gas thermostat
- Belimo actuator
- Thermal drain safety
Dry split logs with a moisture content of about 12–20 % are used as fuel.
Efficiency & Environment
Thanks to wood gasification technology, the ATMOS DC22GSE achieves high energy efficiency while reducing emissions.
- Energy efficiency class: A+
- Boiler efficiency: up to 91.8 %
- Meets BImSchV Stage II
This makes the boiler suitable for modern heating systems using renewable fuels.
Compatibility & System Integration
Wood gasification boilers are typically combined with buffer tanks to efficiently store the generated heat and distribute it within the heating system.
Typical combinations:
- Buffer tank
- Return temperature boost
- Radiator heating
- Underfloor heating
- Thermal solar systems
