Solar Water Heaters – Components, Working, Uses And Types

In every world, the most common application of solar moving picture is heating. Solar water heaters are devices that heat for household, industrial and public publication needs using solar life. A solar water system as soon as carrying out of 100 litres per hours of daylight can annually save up to 1500 units of electricity.

The Components

A solar heating system comprises of a flat plate solar squirrel, connecting pipes (which carry water from the saver to the tank, and to the decline enthusiast), and a storage tank.

The saver contains copper sheets comprising of copper tubes welded together (coated gone a black coating for terribly absorbance) aligned to an insulating material at the urge almost and a toughened glass sheet in credit to top. A flat box houses every one assembly.
In some models, the copper sheets are replaced by evacuated glass tubes. In such models, insulating box and lid sheet are not facility.
Its Working
The Solar Water Heater system is usually installed upon an realize into arena or the roof. The saver is placed such that it faces the sun. This system is related to a continuous supply. It flows through the tubes gets frustrated by absorbing the sun’s heat. The so gnashing your teeth is stored in a tank for difficult use. The insulation in the storage tank keeps it hot overnight. Thus, the absorption of solar radiation by the black surfaces helps in heating, and the insulation of the pipes and the storage tank helps in keeping hot.

Its Uses

Water irate can be used for cleaning, washing and bathing.
By using this, you can save electricity spent by an electric geyser. It along with saves cost used upon attainment generation. Thus, you can contribute to the nation’s economy as dexterously by going solar.
It ensures that you have uninterrupted supply though there are attainment cuts in your place.
They are non-polluting. By going for this you can prevent carbon-dioxide emission. Thus, it has environmental support too.
They have a life span of 15-20 years.
Types of Heating Systems
These systems are of three types. These put in the flat plate collectors, evacuated tube collectors, and concentrating collectors. The most common type used in residential settings in our country are the flat plate collectors. In comparison to its counterparts, it is cheaper. Evacuated tube collectors are not commonly handy, but have been proposed for residential systems. For industrial use and gift generation, concentrating collectors are useful.
