Working Principle
When the sun's energy shines on the solar collectors, it is absorbed and stored. Once the temperature of the collectors reaches the predetermined level, the circulating pump is activated and starts to move the heat transfer fluid through the coil. This transfers the stored heat energy to the water, providing a sustainable and environmentally friendly way to heat water for various purposes.
