Copper coil solar hot water heater

Advantage:
1. Fast coming hot water
2. Auto water refilling
3. Water we use is hot anytime

Working pricinples:
This 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 has 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 a 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 0.3MPA.

Necessary parts:
Tank( with a copper coil inside),
The three-high vacuum tube,
Bracket
Assistant tank

Optional parts:
Microcomputer controller: Show and control the tank temperature
Electric heater---when without sunshine, etc: In rain days and winter days, use for heating water.
Magnesium bar---clear the water scale

This system adopts copper coil as the heat exchanger, (as the copper can purify the water), so it can supply hot water with high quality, clean and even drinkable.
And as copper coil transfer the heat rapidly, so it can ensure that the water is always hot.
