Low Pressure Solar Water Heater
Low Pressure Solar water heater is very popular in many countries and area, such as India, Mexico, Vietnam, China, Chile ,Africa Middle East etc.
A:Features and advantages:
2. Suitable for projects and home use.
3. Designed for commercial solar water heating applications.
4. Reliable and efficient with twin-glass solar tubes.
5. Polyurethane insulation ensures a good heating performance and minimal heat loss.
6. Easy plug-in installation.
7. Can be connected in series to increase water heating capacity.
1. Non-pressure solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becaomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.
