Solar water heater is a best water heating solution in the world. this system is very essential in cold days.solar water heater save electricity in early morning hot water needs. sun light is free in nature for everyone. so always use solar water heater for daily hot water need. these are three solar water heater technification-[1].Radiation:- Sun light or sun heat is called radiation. exp- when metal equipment stand or place in sun light directly it make so hot is an example of radiation.[2] .conduction:- when sun light dropping on metal then reaction are started metal is so going heat first to end then a paint coated polish are observed and store heat in vaccum tube is called conduction.[3].convection:- convection is a process who heat the water in vaccum tube then hot water is slowly going in insulated storage tank is called convection.
Solar Water Geyser
Solar Water Geyser uses the all-glass evacuated solar collectior tubes as the heat absorbing element. The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission which is caused by convection and conduction. The layer films (coating) of the all glass evacuated tubes transfer the sun energy into heat energy. The high absorption and low emittance rate of film is unique. Using thermosiphon system – depending on the different density between hot water and cold water, a water flowing cycle is created in the tubes. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from Solar Water Geyser natural circulation.
Geyser
Hot water heated by the sun is used in many ways. While perhaps best known in a residential setting to provide domestic hot water, solar hot water also has industrial applications, e.g. to generate electricity.
Solar water heaters – also called solar domestic hot water systems — can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use — sunshine — is free.
