Atmos KC35S coal boiler

The Atmos KC35S is an innovative coal gasification boiler that can optionally also be operated with logs as an alternative fuel.

The Atmos KC35S coal-fired boiler was specifically designed for demanding heating needs in single-family homes, holiday homes, agricultural buildings, and workshops. As a robust gasification boiler for wood and coal, the KC35S features a boiler body made of high-quality sheet steel with a material thickness of 6 to 8 mm. Compared to traditional cast iron boilers, this steel boiler offers significantly more efficient heat transfer, resulting in increased energy efficiency.

As a modern coal gasification boiler, the Atmos KC35S is ideally suited as a replacement for outdated models such as the GK21 or other older cast iron boilers. Its design not only allows for the combustion of coal but also enables efficient heating with logs, ensuring a maximum energy efficiency of up to 86%. The KC35S complies with all legal requirements according to the German Federal Immission Control Act (BImSchV) and is therefore approved for operation in Germany.
