Customised, made-to-measure heating solutions


Fascinated by technology

We have always been excited by practical and convenient solutions for climate-friendly heating. For example, GILLES broke new ground with its major contribution to the launch of combustion optimisation using lambda sensors for clean and efficient combustion. We were awarded the Austrian eco-label as one of the first manufacturers of carbon neutral heating systems, and our goal of simply making things better has earned us further international acclaim. Our two Managing Directors, Wolfgang Krämer and Helmut Höllhuber, are committed to continuing this successful mission.


Passion runs in the family

The passion for sustainable heating solutions which inspired the previous generation has passed down to the younger members of the family that owns the business. The two sons of Wolfgang Krämer, Lukas and Wolfgang Krämer jun., now work for the company in the software development, service and sales departments.


Committed to direct customer contact since we were founded in Austria in 1992

Right from the start, it was important to GILLES to be as close to our customers and their needs as possible, in order to develop bespoke heating solutions. The practical experience gained from our design, installation and maintenance service feeds directly into our product development, which ensures excellent practical and customer benefits, and ultimately also helps our installers and sales partners. This applies equally to the direct contact with our service department, which handles technical questions and spare parts deliveries with speed and expertise.


European centre of excellence

With the GILLES Centre in Regau, we have realised our dream of being able to present our developments in a state of the art environment. This training centre is open not only to our customers, but also to employees and sales partners from Austria and all over Europe, offering the opportunity to learn about all our technical developments first hand. It ensures that all GILLES systems can be set up as effectively as possible, regardless of where they are to be used.

The basis of our success – our employees
