This solar water heaters have no pumps. They use water collecting solar heat, and the water tank stores the heat. When people need the hot water, they just turn on the tap on the oulet pipe. The solar water heaters use a heat exchanger to transfer the heat to the running water.
The running water flows through the water tank, but never stays in it. The temperature of outlet water is below 2-3oC in tank.

Features:
1. Pressure water
Without adding booster pumps, the pressure of the hot water from local pipe net. The hot water matches the cold water very well. So it is very easy to adjust water.
2. Clean water
The water is not stored in the tank for a long time. So the hot water is very fresh and clean.
3. Low maintain.
The water tank is no pressure. The water in the tank is still. So there is a little of calcium in the tank. It never needs to clean the inner tank.
4. Good performance in winter
As carefully designed, the water tank is used for storing the heat. There is no water in the outside pipes. Never worry the frost cleft of the pipes.
