District Heating Graz Liebenau
On the roof of the skating hall of the Stadium in Graz Liebenau, a solar thermal system with 1407 m² collector surface was built on
The heat generated by the solar collectors warms the heating water via a plate heat exchanger. The collectors are elevated on the flat roof of the building on a steel substructure.
Solar energy is stored in a 30 m³ steel tank. When the obtained solar thermal energy is not sufficient, the heat is supplied using a conventional water heater.
