Quality and reliability – this is what WIKORA stands for since more than 60 years. Initially founded for the production of charcoal fired hot water heaters, the factory has become a medium sized company with a flexible storage tank production and a comprehensive range of storage tanks and solar products. Competent employees working in the company for many years back this success.

After more than 40 years, as of April 1st, 2017 Mr. Leonhard Jooß handed over the management and joined the advisory board. Mr. Rainer Brauchle, the current director fincance and sales took over the management of the company. In his new function, he is supported by long-term employees and the new proxies Mrs. Silke Hanak (head of finance and purchasing), Mr. Thomas Becker (head of technical department and production) and Mr. Lars Langer (head of logistics, final assembly and IT).

 For our customers, business partners and suppliers nothing changes. You can keep on counting on the high commitment and the well-known high quality.
