The Working Of A Solar Water Heater Explained In Details
A solar water heater is a great alternative for producing hot water every day. Heating water with the help of solar energy is the best alternative way rather than using electricity or gas. A solar water heater consists of solar collectors, a tank and a circulating pump. In some solar water heaters, a backup is also included for the days when solar energy is not available at all and you require hot water. Solar collectors are installed to collect the sunlight. The tank is for storing the hot water and the circulating pump is used for carrying the solar energy from the collector to the tank, and a thermal regulator. Read on to find out more about how a solar water heater works.
The basic function of a solar water heater is that it absorbs light with the help of collectors and then it is converted into heat energy. The circulating pump then passes the heat energy on to the water tank. This exchange is made possible with the help of the thermal regulator. This circulating pump is the reason why you don’t need electricity at all. It also prevents your water heater from overheating.
The collectors work best during the midday when the sky is most of the time cloudless and it should be made sure that the collectors are facing south. During the times when sunlight is insufficient, the water is preheated after which the back-up system takes over and bring the water to the needed hot temperature. This is why a solar water heater can be used to produce hot water without emitting any carbon dioxide. To properly know the working of a solar water heater, you should also know that their way of functioning differs due to the varying type of collectors and circulation systems.
Collector Types
1. Batch Collectors:
This type of collector allows the water to remain in the collector for a very long time if the demand for hot water is low. It is not generally used in very cold climates.
2. Flat-plate collectors:
It consists of parallel copper tubes connected at each end by two pipes which are known as the inlet and outlet.
3. Evacuated tube collectors:
These are known as the most efficient collectors. In this, a glass or metal tube is containing the water is surrounded by a larger glass tube.
Circulation Systems
1. Direct systems:
The most common type of system, it circulates water through the solar collectors and then stored in the tank after it is heated.
2. Indirect systems:
It uses a non-freezing liquid to transfer heat from the sun to the water in the tank.
3. Active systems:
This system uses electric pumps, valves and controllers to move water from the collectors to the storage tank.
4. Passive systems:
Natural convection transfers water from the collectors to the tank as it heats up without the help of any pump.
So, buy the best solar water heating system for yourself too after understanding which function will suit you the best.

Solar energy is, of course, an abundant natural resource which is renewable. An alternative to electricity and gas, solar energy is a great power source. As all the other non-renewable resources keep getting used up, this is the right time to start using solar power. Almost everyone requires hot water every day to do a lot of things both in a home or a factory and industry. Imagine the amount of electricity and gas used to heat water all year long by a whole country. If we can replace them with solar water heater, there will be a huge amount of save of both electricity and gas. Our future generation will be a lot better off if we can decrease the use of electricity and gas.
If someone is using gas to heat water, it automatically leads to the emission of carbon dioxide in nature. Other harmful chemicals also get released when using gas or electricity. One of the major cause of pollution is the emission of carbon dioxide through various sources. This has also made holes in the ozone layers. So, if we can control the emission of carbon dioxide by at least to some percentage, it will make a huge difference to nature. While using solar power, no amount of carbon dioxide or any other kinds of harmful gas is emitted. So, if at least 50% of the population of the country starts to use a solar water heater, there will be a major impact on the environment.
Installing a solar water heater might sound like a lot of work. But, you should know it is not only beneficial to the environment but also the people. So, on this World Environment Day, we are urging you to do your part for the environment and install a solar water heater.

Know The Difference Between Solar Panel And Solar Water Heater
As more and more technology is getting improved, people are leaning towards using solar-powered things. From solar batteries to solar phone chargers, all of these have become a lot more popular. But, a lot of people tend to become confused between solar panels and industrial solar water heater and thinks their functions are the same. But in reality, these two things are two very different things. Even though both of these things are used with the help of solar energy and both of them are needed to install on the roof, but that is all they have in common.
Solar Panel
Solar panels are used to make electricity. It is done with the help of photovoltaic effect, where the absorbed sunlight is converted to electricity by extracting the electrons. In a solar panel, the solar cells are made with semiconductor materials like silicon. It has a positive and negative layer that creates a magnetic field. This helps create electricity even in your home. The bigger the size of solar panels the more independent you will be from using the electricity supplied by the government. Large solar panels are efficient enough to generate electricity for a whole house.
Industrial Solar Water Heater
On the other hand, if you are thinking of industrial solar water heater, you should know that it can only be used for heating water. These do not produce any electricity. A solar water heater uses sunlight just like solar panels but turns it into heat. It is made up of solar collectors that have a series of pipes. These pipes turn the solar energy to heat which is then transferred and stored in a water tank. This can be then easily connected to the supplier of the hot water. An industrial solar water heater can even sometimes heat the water of a swimming pool.
Usually, a solar water heater is efficient enough to provide 90% of your hot water in the summer and about 40-60% in the winter. Also, it extends the longevity of your boiler by 60%. It is also recommended that you can use both solar panels and solar water heater to go completely green but it may not be possible for everyone.
But the biggest thing these two have in common is that they are both extremely beneficial for the environment. Whether you use solar panel or an industrial solar water heater, both of them are using solar energy which is renewable and low-cost energy.
