Water heaters are very much used by the developed countries. Earlier it was used as a luxury product, but in recent times water heating accounts for one of the second largest segments of household energy use, after space heating and cooling. The higher energy usage for heating purposes is creating immense pressure on the national grid for excess supply of electricity. Not only this, but it is also affecting electricity prices badly. Traditional heaters, such as geysers and boilers are even more harmful to the environment. The heating process involves the burning of fossil fuels and the emission of greenhouse gas into the environment. In this regard, an alternative technology has come into the picture that can be used to heat water without harming the environment. One such technology is a solar water heater. It simply uses solar power to heat water.
In India, households and businesses are dependent on grid electricity for heating purposes. Water is heated using electricity from the grid, powered largely by coal, which is very harmful to the environment. Most of the households with lower income levels cannot afford to use hot water for their domestic uses. A solar water heater can work as an alternative solution to traditional water heating systems. India has advanced remarkably in the adoption of solar water heaters as alternatives to traditional water heaters. It is estimated that by installing a solar home water heating system, a family can save up to Rs 1000 per month on electricity, and a person can also get a good quality of hot water just like an electric water heater.
Solar water heaters are very economical and affordable because they have a low maintenance cost. India’s solar water heater industries have experienced huge growth over the past 15 years. The potentiality of this eco-friendly SWH market is estimated to reduce both economic and environmental costs of water heating in the long run. At present, more than 50% of the population in the states of Karnataka and Maharashtra are using a solar water heater for home. In India, currently, around 1 million households are using solar water heaters and the growth rate is around 20%. SWH industries in India enjoy a lot of subsidy schemes and thus they are gaining popularity.
In India, the payback period for solar heaters is quite short. It substitutes the need for the electricity which is required to run power-guzzling water heaters in residential and commercial establishments. Solar water heaters are relatively easy to build and install and thus they are quite popular and are gaining success rapidly. Furthermore, low electricity tariffs have contributed a lot to the development of this industry.
People mostly prefer low cost and shorter payback period times. Thus, they have started accepting solar water heaters over traditional electric heaters. To increase the use of domestic solar water heaters, well-known solar heater manufacturing companies should arrange for educational programs to educate people about the benefits of the best quality of solar water heaters. A solar water heater can really help in improving the environmental conditions and can reduce electricity bills as well.Read More

A solar-powered heater can utilize at least 80% of the solar energy and if it is a cloudy day, the backup of the solar water heater will kick in and provide you hot water for your household work.
So, these are the reasons why using a domestic solar water heater can be more beneficial than using an electric water heater for your home. At the end of the day, if you are using a solar water heater then you are saving your own environment by reducing carbon footprints and contributing to a greener and healthier world.Read More
Every part of a solar water heating system is essential and that includes the collectors. The collectors of a solar water heating system are known to collect the sunlight or solar energy to turn it into heat energy. So, if these collectors are not maintained properly, the whole solar water heating system will stop working. One of the problems that occur with a solar water heating system is that on the hot days these collectors tend to overheat.
On a hot summer day, the collectors absorb solar energy more than normal and the solar water heater generates enormous amounts of heat. But the demand for hot water decreases on a hot day, especially for domestic purposes. This gives birth to a condition known as stagnation.
Stagnation is the situation which occurs when the water storage tank heats up to maximum temperature very early in the day. In turn, the movements through the solar collector stops and thus the fluid present in the system starts to get hotter and hotter. This results in a high pressure due to the high temperature that can damage the system in long run. It usually happens due to the contraction and expansion of the system due to heating and cooling.
Also, when the anti-freeze gets overheated every day, it can become acidic which will then react with all the other elements and becomes corrosive. This corrosive element if circulates throughout the system, it will break down all the components in the long run.
In order to keep your solar water heating system running in the long run, you will need to give your solar collectors some overheating protection. The easiest way to do that is to cover your panels or collectors. If your system has accessible flat plate panels, cover them with sheets of plywood. But this is mostly possible if it is installed on the ground. The plywood sheets should fit the panel exactly so that not only it covers it wholly but it also doesn’t damage the panels due to wind.
If your solar water heating system consists of an evacuated solar tube, you can use a customized shade screen to cover them during the hot days. Make sure this shade screen is made with good material that won’t damage your system in any way but can also prevent the collectors from overheating.
Therefore, if you have a solar water heating system in your home, you should take care of your system and prevent overheating.Read More
Solar water heating system has become quite popular and has been used by many people over the years. Not only solar water heating system has a lot of environmental benefits, but it is also quite affordable. But the solar water heater we use now has evolved a lot over the years. It has taken a lot to reach this simplified version of a solar water heater that we use nowadays. the very first one was made in 1891.
Clarence Kemp was the first one to patent it at that time. The first ones became popular in California and by 1920s at least 30% of the population had installed a solar water heater at their home. But the biggest disadvantage of this solar water heater was that it was a metal tank which used the sunlight to heat the water. This meant the water kept in the metal tank had to be under the sun without any lids and unprotected from the germs and dirt. This hot water was not that suitable for drinking purpose or used for cooking. Many people tried to come up with other versions that would make the heating process easy, but the main problem remained the same.
In 1909, William. J bailey made a version of the solar water heater of Kemp. He separated the solar water heater in two different parts. One was the heating element that was kept exposed under the sun and the other one was an insulated storage unit. This storage unit had to inside the house so that people could have hot water day and night. The heating part consisted of pipes attached to a metal sheet in a glass-covered box and it was painter black. The water that needed to be heated was passed through this narrow pipes. To bring more efficiency to the water heater Bailey reduced the volume of water that could be exposed to the sun which heated up the faster.
But from the 1920s to 1940s the market of solar water heater started to dry up during World War II. People started to rely on fossil fuels and started to use a gas water heater. But after that from the 1960s, several countries like Japan, Australia started to come up with a varied version of solar water heating system as they were going through a lack of natural sources after the war. So, solar water heater became their way of getting hot water on a daily basis.
Continuing up to now, solar water heating system has gone through a lot of evolutions and right now it is really affordable and easy to use it.Read More
This year, on 16th September 2020, we will be observing World Ozone Day. On this day, the main aim is to protect the ozone layer by taking several measures. These measures are mainly for controlling total global production and consumption of substances that deplete it. We already know that there is a big hole in the ozone layer due to global warming and it keeps getting bigger every day. If we don’t take initiatives, then very soon it will be become impossible to live on Earth due to too much pollution and global warming. Solostar, a supplier of solar water heaters in West Bengal will tell you what you can do to take part in this day.
One of the effective ways to stop global warming or saving the Earth is to stop using non-renewable resources. Using non-renewable resources like fossil fuels are depleting the resources of Earth. The usage of these fossil fuels to produce electricity or the usage of diesel and petrol for driving cars is increasing pollution day by day. Now, it is not possible to stop using cars or anything that uses electricity. But, we can certainly start using an alternative instead of using up the non-renewable resources and reduce the amount of pollution.
This alternative is using solar energy. Solar energy is being used in a lot of places, especially where there is a lack of fossil fuels. Solar energy can be used to power up a lot of things. From powering up a whole house to solar batteries or solar charger, solar powers can be used in many ways. One of the cheapest way solar energy used nowadays is a solar water heater.
A solar water heater comes in very handy, especially in places where there are too many problems in the supply of electricity and people require hot water throughout the day. Whether it is for your home or your workplace, if you require hot water all the time, you can also install a solar water heater. A solar water heater has collectors that collect the solar energy and turns it into heat energy which heats the water in the insulated tank. This water stays hot for a very long time.
So, if you are also concerned about the environment and want to do your part, you can also buy a solar water heater. After all, it is an investment which can be used for more than 15-20 years without any problem, if maintained properly.Read More

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.
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.
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.Read More
