Pre Heated Solar Water Heater Features
1, Cheap and reliable hot water solution
2, Simple structure, easy to assemble and install.
3, Strong wind, snow and hailstone resistant ability
4, Fresh water, as you don't use the water inside of storage tank, you always have fresh water.
5, The pressurized hot water will make your bath more comfortable.
Working Principle:
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. ).
