Solar water heating (SWH) technologies are a simple, reliable, and cost-effective method of harnessing the sun's energy to provide for the energy needs of homes and businesses. Simply stated, SWH systems collect the energy from the sun to heat air or a fluid. The air or fluid then transfers solar heat directly or indirectly to your water supply.
Each year most of us spend large percentage of the gas in heating water and thereby wasting money as well as polluting nature quite a lot. However, using a solar water heater can be a great way to save some money and help the environment in the long run. The solar water heaters use the sun’s energy to heat the water, which can be used for residential purposes and you can eventually reduce the energy costs.
While having solar water heaters by your side, you can expect around a reduction of 30 to 40% (depending on the efficiency of the model and the amount of energy you use) on your electric bill.
Solar Water Heaters uses the sun’s radiation to heat the water and will be used for domestic as well as for industrial purposes. The water is heated by solar radiation and circulated inside the glass tubes. Solar water heater has two main components, one is the solar collector and other is the tank to store the water.
