We are


Our passion for electrical heating is in our blood. As a family business, we have been living our passion for more than 25 years. Our company and production facilities are located in Sandhausen near Heidelberg – and our products worldwide.

We value and maintain long-term, trusting relationships with our approximately 45 employees, as well as with our customers and system partners. We have high standards – for ourselves above all else. We always strive for the perfect solution. Company founder Bernd Kletti and his daughter, Sina Thomas, see to this together with their highly- motivated employees.
