Atmos KC25S coal boiler

The Atmos KC25S is a high-performance coal gasification boiler that is primarily operated with coal as fuel, but can also efficiently use logs as an alternative fuel.

The Atmos KC25S coal-fired boiler was specifically designed for heating single-family homes, weekend and country houses, workshops, and similar properties. The boiler body is made of high-quality, 6 to 8 mm thick sheet steel, which ensures significantly better heat transfer compared to cast iron boilers. Furthermore, the KC25S offers a reliable and flexible solution for anyone looking for a modern alternative to older cast iron boilers such as the GK21, GK31, or K30 models.

With its sophisticated gasification technology, this coal-fired boiler enables efficient combustion of lignite briquettes, hard coal, and logs. Thanks to its innovative design, the Atmos KC25S achieves an impressive efficiency of up to 86%. At the same time, it meets all current requirements of the German Federal Immission Control Act (BImSchV) and is therefore fully approved for operation in Germany.
