Solar Water Heating system is a common application of SolarPower. The Solar Water Heater finds its usage in every part of our life. The Electrical Water Heater is used to congregate with the daily hot water requirement by a common man. The costs involved with Electric Geysers are much more than installing and running Solar Water Heaters, as the electric water geysers use a lot of electricity power, that is saved in case of using Solar Water Heaters, because they run on Solar Energy. Also, if weuse the Solar Water Heater, they can save the same power for other application by the people. The need of electricity by a normal house hold for his daily lighting requirement is normally 1 Kwh as compared to 4 Kwh for water heating which clearly shows that consumption of Electricity for WaterHeating is much more than for Lighting.

Because Solar water heaters save electricity & thus funds, therefore they are becoming extremely popular. Also, as Electricity is becoming increasingly costlier, there is reason to use Solar Water Heaters instead of Electric Water Heaters. Solar Water Heaters could even turnout to be more reliable than electric power supply (at least in lots of parts of our country). And, they are neat & green & thus reflect one’s dedication for preservation of surroundings, they are safer than electric geysers as they can be installed on the roof and if well designed, may even look pleasant on the roof top of the house.

Solar water heating is now a fully developed technology. Wide spread utilization of solar water heaters can reduce a significant portion of the conventional energy being used for heating water in houses, manufactories and other industrials and commercialplaces. Today in our daily life we need hot water for many uses. Not only for bathing it is required for other applications such as household goods, cleaning of homes,wash of cloths, cooking & many other uses in home, factories, restaurants and industries even for feeding water to boilers at high temperature.

The operating method of solar water heaters is incredibly straightforward to grasp. Common phenomena ascertained in daily life are the key to functioning of solar water heater. A black surface heats up once left within the sun, by inclusiveness of solar eradiation & second, the interior of it becomes highly regarded, if it’s left within the sun with windows closed. The interior of solar water heater becomes warm in the sun, as a effect of radiation that passes through the glass windows. The basic principle behind this is the famous Green House sequel. The good inclusiveness property of black superficies is employed to boost solar power absorption in a heater. These two phenomena are utilised in basically collectors of star water heaters out there. A typical domestic solar hot-water heater consists of a tank and warmth collectors. The collectors are glazed on the sun facing side to permit radiation to come back in. A black engrossing surface (absorber) within the collectors absorbs solar radiation and transfers the energy to water flowing through it. Heated water is collected within the tank that is insulated to stop heat loss.

Domestic solar water heaters work on the tenet of thermosyphonic impact. Circulation of water from the tank through the collectors and back to the tank continues mechanically owing to density distinction between hot and icy water. No electricity is critical for circulation of water or for the other operation in such systems. However, just in case a back up heater is provided to require care of plight demand in the cloudy days, electricity is going to be necessary.

Since, Solar Water Heaters use renewable energy, their use must be promoted.

And, all effort has been done to make Solar Water Heaters enticing and economical as compared to conventional Electric Water Heaters and therefore, today Solar Water Heaters/Geysers are extremely cost effective.
