solar water heating system

Working principle
As water in the collector is heated, it becomes lighter and naturally rises into the tank above.  Then the hot flows into the left tanks. Meanwhile, cooler water in the right tank flows downwards into the collector, thus causes circulation throughout the system. 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 differrent. When the cold water is put into the collector, it flows into the hot water and mixes with hot water directly. So the tempreture 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 electricty is saved. 

Features

* Choose materials carefully and designed specially for excellent products.

Compared with separate water tanks, we have these advantages

1. The higher tank is the cold water tank. There is an adding water controller in it, so the water can be added automatically. Because the controller is in the cold water, it has long life. The separate water tank must supply water manually

2. The cold water tank combines with the hot water tank perfectly because of scientific design, so it can supply water stablly, fix easily and at low cost and has a beautiful appearance. The separate tank can’t do those and very expensive

3. The water is clear, can be used in winter  because of the insulation layer and can be used for the solar water tank and daily life. The sepatate tank is dirty and can’t be used in winter. 

4. It is very useful for the places whithout running water or the water pressure is not stable

5. The lower tank adopts unique dual-core technology, assuring hot water all the year round

6. Temperature preservation is equipped with standard electric water heater . 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 electricty is saved

7. It can add water automatically

8. Scientifically designed bracket can hold the tank firmly

9. High quality vavuum tubes

10. Simple structure, easy plug-in installation

11. Guaranty: 5 years for tank, 15 years for collector and lifetime service

 12. Colors according to customers’ needs
