Solar hot water Energy

Thermosyphon solar water heaters are widely used for domestic water heating due to their simplicity in construction, installation and maintenance and their cost effectiveness as compared to conventional methods of water heating.

In Cyprus, for example, it is estimated that there are more than 130,000 units in operation, which means one solar water heater for five people in the island. According to Construction and Housing Statistics for 1987 [1 ], about 87% of new dwellings built in 1987 have been equipped with solar water heaters as compared to 69% in 1982.
