The company ratiotherm

The profession became a vocation!

Experience and quality successfully combined

The vision of “heating with maximum energy efficiency” was the basis for the founding of ratiotherm Heizung und Solartechnik GmbH & Co. KG. In the early 1990s, company founder Alfons Kruck developed the Oskar° stratified storage tank, which, with its patented thermohydraulics, is still the technology leader in the stratified storage tank segment today. Almost 30 years and numerous new product developments later, ratiotherm is a full-range supplier of renewable energy systems. Responsibility, the highest quality standards, and technological foresight determine the strategic development of the owner-managed company. As a result, a large number of product developments have been brought to patent maturity, always with a focus on renewable energy sources such as geothermal and solar energy, which are free and crisis-proof. Production at the company’s headquarters in Dollnstein, Upper Bavaria, and system partnerships are further hallmarks of ratiotherm’s high quality standards. Employees with many years of experience produce state-of-the-art heating technology in a total of 3,500 square meters of production space. Several hundred installation companies in Germany and many other partners throughout Europe are trained as system partners for ratiotherm energy systems, thus ensuring the highest quality of products in use on site.

At ratiotherm, we are happy to take on responsibility towards the end customer, thereby justifying the trust placed in us and our local tradespeople. Whether it’s private individuals for whom their own home is a place of family, safety, and security, and for whom the functional reliability of the system is an important part of their quality of life. Or whether it’s companies that demonstrate responsibility for the environment and for whom the investment simply has to pay off for years to come.
