HELIOS – SOLAR DISTRICT HEATING
SOLID planned and built the second and third construction phase of the project Helios in Graz
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.
