A rich history

Konus Kessel GmbH was founded in Germany in 1966. The former owners had been involved in the design and manufacture of combustion plants for more than six years. In 1973 they entered into a partnership with Buderus, followed in 1986 by Deutsche Babcock. When a collaboration with Bertrams followed in 1995, the company name changed to Bertrams Konus GmbH. Five years later, a collaboration with Siemelkamp followed and the name changed to GekaKonus. Since 2004 the company is being continued under the name Konutherm, from the headquarters in Baarn.


From 2D to 3D: optimal customer service

Nowadays, we use the computer program Autodesk Inventor for the design of our thermal fluid systems. Thanks to the use of this 3D CAD calculation model, we can easily exchange models with our customers. With only one push on a button clients can thus see whether the design is appropriate within the overall construction of their building project. With this we simplify the implementation of thermal heaters. This is also the quality and service we stand for at Konutherm.


Our experts are at your service and are pleased to advise you on our heating solutions. Konutherm offers you all-in service for designing, engineering, constructing, converting, and optimizing your thermal heating system. Installation and commissioning and instruction of your staff is executed by our trained engineers observing the relevant regulations.
