ATMOS DC 32 S REG

Product detailed description

The Atmos DC32S REG is a high-efficiency wood-burning boiler designed for installation in residential, commercial, and industrial heating systems. It is commonly used in buildings where a reliable and sustainable heat source is required, such as detached homes, workshops, and small industrial facilities. The boiler is suitable for integration into hydronic heating systems with multiple circuits, including domestic hot water and solar thermal systems. Installers should ensure that the boiler is part of a well-balanced system to maintain efficiency and longevity.

As a generator-type wood-burning boiler, the DC32S REG is designed for long burn times and high thermal output. It is particularly suited for installations where large wood logs are available, and where the system requires a high level of automation and control. The boiler is compatible with standard chimney systems and must be installed in accordance with local building and ventilation codes.

Technical parameters

The technical parameters of the Atmos DC32S REG are essential for proper sizing and system integration. The 35 kW output and 88.9% efficiency indicate that it is suitable for medium to large heating systems. The 80 L water content and 366 kg weight are important for assessing the boiler's thermal inertia and structural requirements. The minimum return water temperature of 65 °C ensures that the system operates efficiently without condensation risks.

Installation and connection

Installation of the Atmos DC32S REG requires a dedicated space with sufficient clearance for maintenance and fuel loading. The boiler should be positioned near the chimney to ensure proper draft and airflow. The chimney must provide a minimum draft of 24 Pa to support the boiler's combustion process. The exhaust flue is connected via a standard flue collar, and the boiler must be integrated into the heating system using appropriate pipe sizes and insulation.

Before commissioning, the installer should verify the fuel chamber capacity, chimney connection, and electrical supply. Common installation errors include incorrect chimney sizing, poor insulation of connecting pipes, and failure to align the boiler with the system's control requirements. The boiler must be level and securely mounted to prevent vibration and structural stress.

Compatibility and accessories

The Atmos DC32S REG is compatible with standard hydronic heating systems and can be integrated with up to three heating circuits, a domestic hot water system, and a solar thermal system. The built-in ACD04 control system allows for seamless integration with additional components such as circulators and expansion tanks. For installations requiring additional control features, the ACD04 system is functionally equivalent to the separately available ACD03 controller.

When ordering, ensure that the necessary piping, insulation, and chimney components are included. The boiler is available in a standard version without the ACD04 control system under the model name ATMOS DC32S.

Technical background for designers

The Atmos DC32S REG operates on the principle of generator-type combustion, where wood is burned in a controlled environment to produce heat. The boiler's body is constructed from high-quality steel plates with thicknesses ranging from 3 to 8 mm, providing structural integrity and heat retention. The fuel chamber is equipped with a gasification nozzle and a longitudinal flue passage to support secondary combustion of gases, improving efficiency and reducing emissions.

The combustion chamber is lined with ceramic refractory bricks to withstand high temperatures and promote complete fuel combustion. The exhaust flue is designed with a vertical channel and a top-mounted flue damper to regulate airflow and temperature. The boiler's built-in exhaust fan ensures efficient removal of combustion byproducts and minimizes dust accumulation in the room.

Designers should consider the boiler's thermal mass and response time when integrating it into a heating system. The system must be balanced to accommodate the boiler's long burn times and high thermal output. The use of a buffer tank is recommended to stabilize the system and prevent thermal shock.

Service and operation

Maintenance of the Atmos DC32S REG includes regular cleaning of the combustion chamber, flue passages, and exhaust fan. The ash removal process is simplified by the large ceramic combustion chamber, allowing for weekly cleaning in most cases. The boiler is equipped with a flue gas thermostat that automatically shuts down the system when the fuel is fully burned, reducing the need for manual intervention.

Installers should check the chimney draft, fuel chamber condition, and control system functionality during routine service. The boiler's high-quality construction and efficient combustion system contribute to a long service life with minimal maintenance requirements.

Frequently asked questions
