Cronius undertook and completed successfully the installation of a forced circulation system for hot water in a tourist accommodation in the city of Florina. The system was equipped with solar panels Cronius S300 type meander. Due to the high efficiency of the collectors S300, we established almost half the m2 of solar panels compared to conventional panels (type harp). Despite the extremely low temperatures that prevail in the region, the system produces hot water, according to the hotel’s needs.
