Tips for solar water heater purchase
1. Choose the reliable manufacturers familiar with foreign trade and good after sale service
2. Find out the way of feeding cold water, the quality of water, the temperature and using habit in your residential area.
3. According to the usage, choose proper model and capacity.
Working principle
Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate. Absorber plates are commonly painted with "selective coatings". Absorber plates are usually made of copper or aluminum because the metal is a good heat conductor. Copper is more expensive, but is a better conductor and less prone to corrosion than aluminum.
Features
1. Collectors are separated from the storage tank. The tank can be put anywhere of the house,so the whole system is harmonious with the building
2. Absorbing heat quickly
3. No worry about being frozen, anti-ice ball.
4. Completely automatic operation
5. Without incrusting, long usage life
6. Multifunction: Bathing, washing, domestic heating
7. Beautiful appearance
