Area of application & Target audience
The ATMOS DC40GSE is a manually fed wood gasification boiler for high-performance log heating systems.
Typical areas of application:
- large detached houses
- Apartment buildings
- Renovation of existing wood heating systems
- New buildings with renewable heating technology
- Heating systems with buffer storage
The installation should be carried out by a qualified plumbing, heating, and air conditioning (PHVAC) specialist.
Everyday benefits
Wood gasification boilers utilize the energy of the fuel particularly efficiently. In the ATMOS DC40GSE, the wood is first gasified and then completely combusted.
This technology provides:
- high energy yield from firewood
- reduced emissions
- consistent heat output
- economical heating operation
The large filling chamber allows for convenient refilling 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 safety device
The operation uses dry firewood with a moisture content of approximately 12–20%.
Efficiency & Environment
Wood gasification technology ensures efficient use of the fuel while simultaneously reducing emissions.
- Energy efficiency class: A+
- Boiler efficiency: up to 90.5%
- Complies with BImSchV Level II
compatibility & System integration
Wood gasification boilers are typically combined with buffer storage tanks. This allows the generated heat to be stored efficiently and distributed throughout the heating system.
Typical combinations:
- Buffer storage
- Return flow increase
- radiator heating
- Underfloor heating
- thermal solar systems
