Jiangsu Sunpower Solar Technology Co,.Ltd. products

The separate pressurized solar water heater compose of solar collector, storage tank, controller, working station and installation parts.

Compulsive recycling means help the system collector absorb the sun energy and transfers it to water tank efficiently. High working efficiency: With the scientific principle, the heat energy can be transferred to water tank on time. Saving energy: Choosing Germany original pump, the electricity consumption is very litter, just only several cents every day. One pump, two functions: Increasing pressure and recycling. Operation easily with an intelligent controller and digital display. Beautiful appearance and easy to be installed.

Water tanks are made by machine. Flower design pressed on aluminum alloy (or stainless steel) shell, beautiful and durable. Inner water tank is made of super SUS304 food grade stainless steel plates, welded by argon arc. Water is pure and drinkable. Warm keeper of water tanks adopts polyurethane`s cellular, thickness is 55mm. Aluminum alloy (or stainless steel) supports are connected by bolts and nuts, firm and stable, easy to install. Between vacuum tubes and inner water tank, we adopt milk white silicon glue rings to connect and seal them. The tubes and supports are adjustable, power bearing is average, and can assure the vacuum tubes to use long time.

Solar water heaters are all-glass evacuated solar domestic water system combined with heat pipes. The selective coating in the inner cover of the evacuated tubes ensures high energy absorption and low heat radiance losses, which convert solar energy into heat energy and transfer to heat pipe by aluminum fin. The liquid in the heat pipe change into vapour by heating, the vapour goes up within the heat pipe. When heat is exchanging between the condenser end of the heat pipe with the water in the tank, it turns into liquid again, then comes down to the base of the heat pipe, this cycle continuously repeats as long as the sun shines. In this way the heat is transferred from heat pipe to the cold water in the tank. When the hot water can be obtained by injecting cold water from the bottom of the tank.
