Pellet boiler Atmos P

The boilers of the ATMOS P pellet boiler series The P14, P21, and P25 are characterized by their automatic, compact, and user-friendly pellet heating systems, requiring minimal maintenance. With a nominal heat output of 14–24 kW for 6–8 mm wood pellets, they cover the heating needs of single-family and multi-family homes. The boilers in the ATMOS P-series are dedicated pellet boilers that can operate independently or, often, in combination with a separate wood-burning boiler. Depending on the installation situation, the burner can be mounted on the left or right side of the boiler. This offers the advantage of keeping it out of the way during cleaning, and all surfaces are easily accessible to the user after opening the large boiler door. As with our other pellet boiler series, pellets are fed via an auger from a separate ATMOS silo, fabric storage unit, or on-site storage room. Depending on the application, we offer augers in lengths of 1.5, 2.0, 2.5, 3.0, and 4.0 meters. Since ATMOS prioritizes the reliability of its pellet boilers, the augers are only designed as a straight-running system!
