The Steigenberger Hotel Der Sonnenhof in Bad Wörishofen has been operating a RENECOST® system from Schuntermann since 2010. We are very satisfied with the product. The technology is low-maintenance and works reliably. The entire project handling and our cooperation with the company have been professional. The energy savings calculated during the quotation and planning phase were contractually guaranteed and have actually been achieved. Due to the voltage reduction, we have also seen a clear decrease in defective lamps. Voltage stabilisation prevents voltage peaks, which are often the cause of the premature failure of LED luminaires. We can recommend the RENECOST® system from Schuntermann without any reservation.

…I would like to once again express my thanks to you for the excellent planning, delivery and installation of the RENECOST® system. The cooperation between all parties involved in the project was outstanding, and the result matches the energy savings you predicted. This means we will achieve the originally projected payback period of the system and have made a significant contribution to reducing energy costs for the city, as well as to environmental protection. Many thanks!
