Solar water heater :
working principle:
1.thermosiphon solar water heater works in this way:warm water rises when the phenomenon known as natural convection happens and water circulates between the collectors and tank.the tank must be installed above the collector.
2.as water in the collector is heated,it becomes lighter and naturally rises into the tank above.meanwhile,cooler water in the tank flows downwards into the collector,thus causes circulation throughout the system,these systems ard reliable and relatively inexpensive.
