Non-pressure Flat Plate Solar Heater

Non-pressure flat plate solar water heater working principle:

Non-pressure solar water heater is such a kind of thermosiphon solar water heating device, which flat plate collector placed below high pressure hot water tank. The tank and flat plate are connected with two circulation pipes to form a open-loop solar water heating system, tank is non-pressure design, based on gravity. The whole system only use water, can’t use other liquid as circulation medium. By continuously circulating in this way, the water is heated directly inside flat collector and rise to be stored inside hot water tank.

Non-pressure flat plate solar water heater characteristic:

1. Low cost, most economic among flat plate solar water heater.

2. Water tank non-pressure design, just based on the gravity.

3. Suitable for hot area, where is no frozen risk area.

4. No Glycol, No Chemicals!

Non-pressurized Solar Water Heater Key Components:

① Outer tank ② Cold water inlet ③ Magnesium rod ④ Air vent ⑤ Insulation layer ⑥ Inner tank ⑦ Electric heater ⑧ Hot water outlet ⑨ Circulation outlet ⑩ Cold water inlet ⑪ Tempered glass ⑫ Header tube ⑬ Back sheet ⑭ Insulation layer ⑮ Riser pipe ⑯ Absorber plate ⑰ Frame ⑱ Support
