UnderstandingSolarWaterHeaterPrinciple

Solarwaterheaterisanexcellentalternativetothetraditionalmodeofwaterheating,whichdependsontheuseofnon-renewableresourcessuchascoal,gas,andelectricity.Itisaclean,safe,andpocket-friendlymethodofwaterheatingthatutilizestheenergyofthesuntoheatwater.Inthisarticle,wewilldiscusstheprinciplebehindsolarwaterheatersandhowtheywork.

PrincipleofSolarWaterHeater

Thebasicprincipleofasolarwaterheateristoharnesstheenergyofthesuntoheatwater.Itworksbycollectingheatfromthesunwiththehelpofsolarcollectors,whichareusuallyinstalledontheroofofthehouse.Thesolarcollectorsaredesignedtoabsorbsolarradiationandconvertitintothermalenergy.Thisthermalenergyistransferredtothewaterstoredinastoragetank,whichisthenusedforvariouspurposeslikebathing,washing,andcooking.

WorkingofSolarWaterHeater
