Solar water heating system uses a roof mounted collector, angle towards the south to capture heat from the sun. The collector may be a flat panel, or a series of vacuum tubes in both cases it contains a heating fluid which is warmed by the sun’s rays and then pumped through a heat exchange coil in the hot water tank. As the coil warms up, it transfers the heat to the water in the tank. Any solar based system will need a conventional water heater powered by gas or electric to provide back up.
