From a manufacturer to the brand

The company KWB - Kraft und Wärme aus Biomasse GmbH (power and heat from biomass) was founded in 1994 from the mechanic and organic farmer Erwin Stubenschrott and additional partners in Graz.

Three years later the company moved to St. Margarethen/Raab in Eastern-Styria. Since then the company has continuously expanded. In 2000, a second production hall was built, followed by the construction of a third only one year later. In 2003, the KWB Competence Centre was constructed. It is used to link industry expertise and image building.


The strong demand for biomass heating systems all across Europe led to the establishment of subsidiaries in Germany, Italy and France. In Ireland, the U.K., Belgium, the Netherlands, Luxembourg, Slovenia, Spain, Chile and severeal other countries, KWB is represented by strong sales partnerships.

In the meantime, KWB has become known for its innovative edge with respect to renewable heating systems.
