Working principle:
The collector absorbs solar energy and transmits it to the water tank through circulation.
When the temperature of the collector reaches the set value, the controller
starts the circulation pump automatically.

Shentai solar water heater features:
a. Module design, arbitrary combination, harmony with the building perfectly
b. Intelligent control and automatic operation
c. Anti-freeze: Using the anti-freezing liquid as the medium and the controller has
the anti-freezing function
d. Multifunction: bathing, washing, domestic heating etc.
e. Work at anytime and enjoyable.
