Using the sun’s energy to heat water is not a new idea. More than one hundred years ago, black painted water tanks were used as simple solar water heaters in a number of countries. Solar water heating (SWH) technology has greatly improved during the past century. Today there are more than 30 million m2 of solar collectors installed around the globe. In addition to the energy cost savings on water heating, there are several other benefits derived from using the sun’s energy to heat water. Most solar water heaters come with an additional water tank, which feeds the conventional hot water tank. In the present work a concentric tubular type solar water heater have been designed to get maximum effectiveness. It is found that temperature has increased so much as compared to uncoated pipe.
