This type uses the all-glass evacuated solar collector tubes as the heat-absorbing element. The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission which is caused by convection and conduction. The layer films(coating) of the all-glass evacuated tubes transfer the sun energy into heat energy. The high absorption and low emittance rate of film is unique. Using thermosiphon system-Depending on the different density between hot water and cold water, a water flowing cycle is created in the tubes.

Using thermosiphon system-Depending on the different density between hot water and cold water, a water flowing cycle is created in the tubes. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this natural circulation.

Works with high pressure. Therefore, the warm water conies out with pressure too. It uses the heat pipe to delivery heat energy; water is heated rapidly. Each tube can work alone, so it can work even if one tube is broken.

When the temperature of the heat collector 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 the heat exchanger in the water tank. In case the temperature of the circulation pump does not reach the set value. the circulation pump shall be working automatically. In case the temperature of the water tank does not reach Tmax .then start then electrical heater.

Working principle: embraces tightly the U copper pipe with solar fluid.The fin touch precisely to the inner glass tube and transfers it to the solar fluid inside the copper pipe.the entire inner surface of the evacuated tube and header pipe. An aluminum fin conducts heat from tube) and when warmed up,it returns up to the which inserted inside the vacuum tube (evacuated The fluid passes through the U-shaped copper pipe with solar fluid.

The pipeline is made of all the red copper and conducted by heat transfer medium liquid. Water can`t flow in vacuum tubes and operated. The manifold uses Aluminum alloy mould material of high strength with Air flow design. It is furnished in good style. Can withstand high pressure when it works. Module design, arbitrary combination, which can meet the demand of large water consumption.

Source Heat Pump Water Heater work based on inverse carnot cycle principle , with small amounts of electrical energy as a driving force, the refrigerant as the carrier, absorb the hard-to-use low grade heat from the air and convert to available high grade heat, realize the conversion from low temperature heat to high temperature heat, and than release the high grade heat into the water for making hot domestic water.
