The separate pressurized solar water heater composes of solar collector, storage tank and controller.ÿWorking principle1) 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 the T max, then start the auxiliary heating device.5) If discrepant temperature of the collector and the water tank does not reach the set value, the circulation pump shall be shut automatically.ÿÿCharacteristics1) Collector separates with the storage tank. The tank can be put anywhere of the house2) And the collector can be put on both tilted roof and flat roof3) Module design, arbitrary combination, harmony with the building perfectly4) Intelligent control and automatic operation5) Anti-freeze: no water inside the tubes when it works6) The system controller has the anti-freezing function is that the temperature circulation will operate while it reaches the fixed temperature7) Multifunction: Bathing, washing, domestic heating8) Workable at anytime and enjoyable
