Page 8: Working Principle
Working Principle of a Solar Water heater A solar water heating system consists of a vacuum glass tube collector, an insulated storage tank and connecting stand parts (page 4). The evacuated glass tubes are filled with water and exposed to sun, thus heating up the water in the glass tubes. As the specific gravity of cold water is heavier than hot water, the hot water in the glass tubes starts rising in the insulated water tank, and the cold water in the insulated water tank sinks into the glass tubes.

Thermosiphon Hot water Cold water Main tank Tube Per formance The output of a solar water heater system will depend on the amount of solar radiation available. On a good sunny day with 6 to 7 hours of sunlight, the glass tubes will collect enough solar energy to heat water up to 60 C.

Page 13: Optimal Usage
Optimal Usage Tips / Maintenance There our some recommendations and tips which if followed can go a long way to improve the over all efficiency of the solar water heater. Plan the consumption of hot water in quick intervals at one time (either in the morning or evening) to minimize heat loss in the pipeline.
