Introduction :
Pre-heated solar water heater also relies on the natural circulation of water between the collector and the tank (that is tubes absorb solar energy, and heats the water inside the tube,hot water rises, cold water flows down).
It differs from compact non-pressurized solar water heater because it gets a copper coil inside the inner tank. The hot water rises from the tube into the tank, and heats the copper coil and finaly heats the water inside the copper coil . Therefore the water tank is just as heat storage tank.
so the hot water we use is actually from the copper coil, it'is more clean,and even drinkable(as the copper can purify the water.).The whole system also works at 0.2-0.6MPA.
One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up), so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using a gravity feed tank or pressure reduction valve.
Necessary parts:
Tank( with a copper coil inside), vacuum tube, bracket
optional parts:
A controller----show water level, temparature for the conveince of cold water supply
Assistant tank---fill water in time constantly
An electric heater--- use for heating water in rainy or windy days

Assistant tank: 5L,8L,10L,12L(Red,green,blue,black,white,violet)
Working principle:
1. The high quality vacuum tubes absorb the solar ultraviolet ray and visible light; then heat the cold water in the vacuum tube.
2. The hot water rise in the top of the water tank, and the cold water sink to bottom then heat by solar collector. So the whole system is always circulating continuously. The water we use that is in the copper coil, not in the water tank, the tap water connect to the copper coil directly, the hot water in the water tank exchange the heat with the tap water in the copper coil
3. The Assistant water tank can perform the water supply automatically, the water in the tank is not sufficient, the electromagnetism valve will open its valve, the tap water flow in the water tank, if the water is full, it will close the valve automatically
4. The whole system can endure high pressure according to the pressure-bearing technology
