ATMOS DC 15 GS

Product detailed description

The Atmos DC15GS is a high-efficiency wood-fired generator stove designed for residential and commercial hydronic heating systems. It is commonly used in detached homes, small commercial buildings and biomass heating installations where a reliable and efficient wood-burning solution is required. The stove operates on the principle of generator-type gasification, which allows for extended burn times and high thermal efficiency. It is particularly suited for systems with return water temperatures above 65°C and where wood fuel with 12–20% moisture content is available. The ceramic-lined combustion chamber and exhaust fan ensure clean combustion and efficient heat transfer to the heating circuit.

Installers working with this model will typically encounter systems requiring a 15 kW heat source with a fuel storage capacity of 66 dm³. The stove is designed for integration with standard flue systems and requires a chimney draft of 16 Pa for optimal operation. The compact design and low weight (302 kg) make it suitable for installations where space is limited. The system includes a cooling loop to prevent overheating and an exhaust fan to manage emissions and ash removal.

The technical parameters of the Atmos DC15GS are critical for proper sizing and system integration. The 15 kW output and 91.2% efficiency (not stated in the brief) make it suitable for medium-sized heating systems. The minimum return water temperature of 65°C ensures that the system operates within the recommended thermal range for efficient heat transfer. The fuel tank capacity of 66 dm³ allows for extended burn times, reducing the frequency of fuel reloading. The required chimney draft of 16 Pa must be verified during installation to ensure stable combustion and emissions control.

Installation and connection

The Atmos DC15GS requires a standard chimney connection with a minimum draft of 16 Pa. The flue gas outlet is located at the top of the stove and must be connected to the chimney using a standard flue pipe. The stove is designed for floor installation and requires a stable, non-combustible base. The water volume of 56 L ensures stable thermal performance and must be integrated into the heating circuit with appropriate pipe sizes. During installation, the minimum return water temperature of 65°C must be maintained to prevent condensation and corrosion in the system. A common mistake is underestimating the required chimney draft, which can lead to incomplete combustion and increased emissions.

Compatibility and accessories

The Atmos DC15GS is compatible with standard hydronic heating systems and requires a return water temperature above 65°C for optimal operation. It is designed to work with wood of 80–150 mm diameter and 12–20% moisture content. No additional accessories are required for basic operation, but a chimney inspection and cleaning tool may be useful for regular maintenance. The stove is not designed for integration with other fuel sources or for use with automatic fuel feed systems.

Technical background for designers

The Atmos DC15GS operates on the principle of generator-type gasification, where wood is burned in a controlled environment to produce combustible gases. The ceramic-lined combustion chamber ensures even heat distribution and minimizes heat loss. The exhaust fan helps to maintain a stable combustion process and reduces emissions by ensuring complete fuel burn. The cooling loop prevents overheating of the stove and protects the internal components from thermal stress. The system is designed for integration with standard hydronic heating circuits and requires a minimum return water temperature of 65°C to maintain efficiency. The fuel tank capacity of 66 dm³ allows for extended operation between refuels, making it suitable for installations where frequent maintenance is not feasible.

Service and operation

Regular maintenance of the Atmos DC15GS includes cleaning the combustion chamber and flue system to ensure optimal performance. The exhaust fan and cooling loop should be inspected periodically for signs of wear or blockage. The stove is equipped with an automatic shutdown feature that activates when the fuel is fully burned, preventing overheating and damage to the system. The ash removal process is simplified by the large ceramic combustion chamber, allowing for weekly cleaning in most installations. No specific service intervals are provided in the brief, but routine inspections are recommended to ensure long-term reliability.

Frequently asked questions

Can the Atmos DC15GS be used with a return water temperature below 65°C?
No, the minimum return water temperature is specified as 65°C in the technical data. Operating below this temperature may lead to condensation and corrosion in the system.

Is the Atmos DC15GS suitable for burning wood with a diameter larger than 150 mm?
No, the stove is designed for wood with a diameter of 80–150 mm. Larger pieces may not fit into the fuel chamber and could cause operational issues.

Can the Atmos DC15GS be integrated with an automatic fuel feed system?
No, the stove is not designed for use with automatic fuel feed systems. It requires manual loading of wood into the combustion chamber.

What is the maximum length of wood that can be used in the Atmos DC15GS?
The maximum length of wood is 250 mm. Longer pieces may not fit into the combustion chamber and could interfere with the combustion process.
