Solar Water Heater

Product name: Split solar water heater; Solar water heater system; Separated pressurized solar water heater.
The system of split solar water heater is consist of water tank, solar collector, working station or controller.

Working principle:
1) When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically.
2) The circulation pump makes heat-conducting liquid circulate automatically.
3) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank.
4) In case the temperature of the water tank does not reach max, then start the auxiliary heating device
