Already in 2014, more than a year before the introduction of the first stage of the Ecodesign Directive ErP for heating systems and components, the successful co-operation between VIESSMANN SAS in Faulquemont and va-Q-tec Thermal Solutions GmbH from Würzburg started. The focus was not only on the usage of highly efficient VIPs, but also on a design that is as effective as possible and on integration into the production process as efficiently as possible. By means of the usage of VIPs, VIESSMANN was able to successfully position quality hot water tanks on the market initially in the highest energy efficiency class A and later also in A+. The portfolio was not only expanded in this way, together a good contribution was also made to the topic of energy efficiency.
