Working principle:
* The separate pressurized solar water heater compose of solar collector, storage tank, controller, working station and installation parts.
* When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically.
* The circulation pump makes heat-conducting liquid circulate automatically.
* The heat-conducting liquid transfers heat to water by heat exchanger in the water tank.
* In case the temperature of the water tank does not reach T-max, then start the auxiliary heating device.
* If discrepant temperature of the collector and the water tank does not reach the set value, the circulation pump shall be shut automatically.

Features:

* Collector separates with the storage tank. The tank can be put anywhere of the house.
* Module design, arbitrary combination, harmony with the building perfectly.
* Intelligent control and automatic operation.
* Anti-freeze: No water inside the tubes when it works.
* The system controller has the anti-freezing function is that the temperature circulation will operate while it reaches the fixed temperature.
