Solar Heating System for Hot Water Supply, Volochysk

All-Season Solar Water Heating System

The project involves the installation of 12 flat solar collectors Hewalex KS2100F TPL AC with a total absorber area of 24.7 m². The system is designed to meet a daily demand of 1,000 liters of hot water at 65°C.
Two ABD-0500 water heaters (500 L each) with dual heat exchangers are used.
The SR658 controller automatically manages the operation of circulation pumps based on temperature sensors.
