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
