The solar water heating project works on the principle of exchanging the solar energy to heat energy. The hot water is transmitted to the storage cylinder by circulation pipelines. The water colder and heavier in the bottom of the storage cylinder moves to the solar collector "passively" or "actively".
The solar water heating project system is usually combined by multiple solar collectors in series or in parallel or by multiple solar water heaters in series or in parallel. The circulation, water temperature and startup time of the system can be controlled by intelligent controller to ensure the system works perfectly.
The system can be used safely and the maintenance is easy. According to the water quantity, installation area and users' requirement the collectors can be arrayed flexibly. The electric boosting system is installed inside the storage cylinder. According to the requirement and the actual situation the electric heating element can be increased or reduced to get hot water in rainy days and cloudy days and to realize the complementary between sunshine and electricity, microcomputer intelligent control and auto hot water supply in all year round.
