1)Use the copper coil as the heat exchanger, according with international fashion trend it is easy to install and use.

2) It takes the advantage of the tap water's pressure.more pressure ,more comfortable.

3) It can produce hot water with constant temperature, it is safe and comfortable to use.

4) The water can be heated rapidly, so it can produce the high quality hot water.

5) It can produce more hot water than the general types because it isn't. downward and hot water goes upward. The water will be heated continuously between water tank and vacuum tube.In other wards, hot water always floats on cold water, The hot-water flows to the water tank from the vacuum tubes, Because of the proportion, cold water flows to vacuum tubes from the water tank, The cold water is heated in vacuum tubes.After it becomes hot water, it flows to water tank again. The water circulates constantly between water tank and vacuum tubes; the cold water in water tank will be hotter and hotter.

Finally, all cold water will be heated to be hot water in tank. This is the heating course of cold water.

6)due to the copper coil is in tank,when water is very hot,so when you open the cold water flow the copper coil,the water in tank will heat water flowing copper coil,so when you use water from copper coil,the water is hot,the difference is less than 5 degree between tank and copper coil.and the press of hot water from copper coil is same with city water.
