Installation of Solar Water Heating Systems in Preschool “Sonechko” and Child Development Center “Kalynka”, Volochysk

Implementation of All-Season Solar Water Heating Systems

The project includes installing 8 all-season flat solar collectors Hewalex KS2100F TPL AC and two 300-liter heat exchanger tanks on the rooftops of each of the following institutions:

• Preschool “Sonechko” (1/2 Soborna St.)

• Child Development Center “Kalynka” (2a Muzeina St.)

The system will supply hot water to the kitchens for cooking, dishwashing, and other utility needs. This will significantly reduce electricity usage and offer partial energy autonomy in case of power outages.

The solar system operates automatically: a controller manages the circulation pump based on the temperature difference between the collector and storage tank, ensuring maximum efficiency in solar energy use.
