3. Advantages:
1. Use the copper coil as the heat exchanger, it is the international development trend, it is simple to install and use.
2. It takes the advantage of the tap water's pressure, bring a high pressure hot water flow out.
3. It can produce hot water with constant temperature, safe and comfortable to use.
4. The water can be heated rapidly, so it can produce the high temperature hot water.
5. It can produce more hot water than the general types because it isn't restricted by the volume of the tank.
6. With the assistant tank, cold water feeding automatically.
7. The water you actually using is the water in the copper coil. It ensures fresh water for shower.

4. Working principles: 

SUN-SEEKER copper coil Preheated solar water heater provide mains pressure via a high efficiency copper coil heat exchanger which located within the tank.

 

1. For water in the main tank, principle is the same as the non-pressure solar collector:

All-glass evacuated tubes absorb and transfer sun energy into heat energy, then heat water inside vacuum tubes. Depend on the different density between the hot water and cold water; a cycle can be created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank becomes hotter and hotter.

 

2. for water in the copper coil:

When cold water flows through the coil it absorbs heat from the water inside the pre-heating tank. And the water we actually use is the water in the copper coil, it means it is the fresh water (there is no pollution in the water).
