Solar Water Heater

Solar Water Heater
Product Detailed
1) OEM service supply 2) Higher heat efficiency 3) Freeze protection

Working principle:

Solar vacuum tube was evacuated into the tank,the coating inside of tube can absorb more than 92% heat energy from sunshine,The cold water in water tank flows into the tube and become hot, because of different density between cold and hot,there will be a natual circulation in the tube.Hot water will float back to tank.

The polyurethane heat insulation layer can keep the water warm about 2days without any sunshine. Consumer can enjoy comfortable bathe anytime.

The details of material:Evacuated tube: High quality borosilicate glass 3.3, Φ47×1500,  Φ58×1800/2100, Φ70×2100Inner tank:SUS304-2B stainless steel plateOuter tank: Enamel steel plateInsulating layer: Polyurethane foamBracket: Aluminum alloyThe principle of thermosyphon:Because of the larger proportion of hot water than cold water, cold water flows downward and hot water goes upward. The water will be heated continuously between water tank and vacuum tube. In other wards, hot water always floats on cold water.The hot-water flows to the water tank from the vacuum tubes. Because of the proportion, cold water flows to vacuum tubes from the water tank. The cold water is heated in vacuum tubes. After it becomes hot water, it flows to water tank again. The water circulates constantly between water tank and vacuum tubes; the cold water in water tank will be hotter and hotter. Finally, all cold water will be heated to be hot water. This is the heating course of cold water.
