Coal boiler Atmos KC45S

The Atmos KC45S is a modern coal gasification boiler that can be operated not only with coal but also efficiently with logs.

This gasification boiler is a specially designed boiler for burning coal and wood. The Atmos KC45S is ideal for heating single-family homes, weekend cottages, country houses, workshops, and similar properties. The boiler body is made of high-quality sheet steel with a thickness of 6 or 8 mm, ensuring particularly good heat transfer compared to conventional cast iron boilers.

As a reliable replacement boiler, the Atmos KC45S coal-fired boiler is particularly recommended for replacing older cast iron boilers like the GK21. Its robust construction and versatility make it the ideal solution for modernized heating systems.

The Atmos KC series was specifically developed as a replacement for outdated cast coal boilers, such as models like the GK21, GK31, or K30. The KC45S offers not only high efficiency but also the flexibility to operate as both a coal-fired and a wood-fired boiler, achieving a maximum efficiency of up to 86%. The boiler meets all legal requirements of the Federal Immission Control Ordinance (BImSchV), making its use in Germany unrestricted.
