LINDNER CONGRESS HOTEL,
DUESSELDORF, GERMANY
Hotel Lindner consists of 230 rooms, 10,500 m² heated area with an energy consumption of 3,900 MWh. It had rigorous requirements on warm water and heating comfort. The energy costs made up too large a portion of the overall operating costs of the hotel. The convenience of the heating and warm water did not meet the requirements. Hotel Lindner therefore decided on a new, modern heating solution. The greatest challenge was that the renovation was to be carried out in parallel to the daily running of the hotel. Two gas condensing boilers R 3603 were arranged in a cascade. This gives a total power of 1,692 kW, which is adjusted by modulation.
