ATMOS DC40GSE wood gasification boiler 40 kW
The ATMOS DC40GSE wood gasification boiler is a powerful solid fuel boiler for the efficient combustion of split logs. With a nominal heat output of 40 kW, the model is particularly suitable for larger single-family homes, multi-family houses, or commercial heating systems.
Thanks to modern wood gasification technology, the fuel is used particularly efficiently. The ATMOS DC40GSE achieves high efficiency levels and meets the requirements of BImSchV Stage II. The energy efficiency class is A+.
Highlights / Advantages
- ⭐ Wood gasification boiler with 40 kW output for large heating systems
- ⭐ Efficiency up to 90.5% for efficient wood combustion
- ⭐ Energy efficiency class A+ according to EU energy label
- ⭐ Suitable for log wood up to 530 mm in length
- ⭐ Meets the requirements of BImSchV Stage II
Application area & target group
The ATMOS DC40GSE is a manually fed wood gasification boiler for high-performance log wood heating systems.
Typical application areas:
- large single-family homes
- multi-family homes
- renovation of existing wood heating systems
- New buildings with renewable heating technology
- Heating systems with buffer storage
Installation should be carried out by a qualified HVAC specialist company.
Everyday benefits
Wood gasification boilers use the energy of the fuel particularly efficiently. In the ATMOS DC40GSE, the wood is first gasified and then completely burned.
This technology provides:
- high energy yield from log wood
- reduced emissions
- uniform heat output
- economical heating operation
The large filling chamber allows for comfortable reloading of logs and supports long heating intervals.
Technology & Equipment
The wood gasification boiler is equipped with an induced draft fan that stabilizes the combustion process and supports the chimney draft.
The most important technical components include:
- Induced draft fan
- Boiler thermostat
- Safety thermostat (STB)
- Flue gas thermostat
- Belimo actuator
- Thermal drain safety device
Operation is carried out with dry split logs with a moisture content of approximately 12–20%.
Efficiency & Environment
The wood gasification technology ensures efficient use of the fuel while simultaneously reducing emissions.
- Energy efficiency class: A+
- Boiler efficiency: up to 90.5%
- Meets BImSchV Stage II
Compatibility & System Integration
Wood gasification boilers are typically combined with buffer tanks. This allows the generated heat to be efficiently stored and distributed in the heating system.
Typical combinations:
- Buffer tank
- Return temperature boost
- Radiator heating
- Underfloor heating
- Thermal solar systems
