Les Iris

Les Iris (Virton, Belgium) wanted to produce its hot water thanks to solar thermal technology. To achieve this project, the board trusted Sunoptimo and its drainback concept. The solar fraction of the installation was optimized, and almost 70% of the hot water needs are covered by the sun. This system is composed of 95 m² of collectors, 5000 of technical water storage and two Optiaqua units which supplies hot water.
