It is possible to generate thermal energy from renewable sources like solar, biomass, and geothermal source of energy. All these systems are together known as renewable source of energy. To put it simply, the systems that change sunshine into usable thermal energy are referred as solar heating and cooling technologies. The sun’s energy is captured through solar heating collectors and the heat gets efficiently transferred to buildings both for heating and cooling purposes.
Let us know a little about the solar water heating technology. Solar water heating systems can be easily installed in most of the US homes and three main elements of these systems comprise the solar collector, the insulated piping, and a hot water storage tank. For colder climates one can use electrical controls as well as a freeze protection system. The process is such that the solar collector gathers heat from solar radiation and transfers the heat to the potable water. The heated water then flows out of the collector to a hot water tank and is used as per requirement. If one desires one can keep the auxiliary heating connected to the hot water tank for any sort of back-up.
