Non-pressure Series Two Pipe Inlet-outlet

We are engaged in trading, exporting and supplying excellent quality Non-Pressure Series Two Pipe Inlet-Outlet to our valuable clients. 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 of the all-glass evacuated tubes transfer the sun energy into heat energy. Depending on the different density between hot water and cold water, a water flowing cycle is created in the tube. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this natural circulation.

Advantage: because the cool water is forever below the hot water,so the water in the left tank is always hot. But other non-pressure solar water heaters are different.When the cold water is put into the collector, it flows into the hot water and mixes with hot water directly. So the temperature falls down quickly. The electric heater is in the left tank. When it is needed, only the water in this tank is heated, so it will be heated very quickly and the electricity is saved.
