In the following article we are going to tell about solar water heaters. It is a technology invented by humans which helps us to get hot water for our use very easily without any kind of expenses on it. Such type of heaters are very efficient to use and are gaining popularity all over the world. Its basic advantage is it heats up water free of cost and without making any sort of damage to the environment. Once it is installed there is no maintenance cost in it and it is efficient enough to supply hot water for more than 5 years. There are solar panels which are present in the heater and there are two different methods by which it works.
The first type of solar water heating system depends on the electricity which is produced by solar energy and there is a pump present which drives the water to the solar panels from the tank and after heating it is again pumped back to the tank. The water which is heated up the moves upside of the pipe and the cold water is settled down for its turn to absorb heat and get hot. The role of the pipe is to circulate hot water and cold water so that total water present in the tank.

The second type of solar water heating system does not have any kind of pump present in it. In this case the water tank is placed in a higher position than the solar panels. The cold water present in the tank is pushed by the hot water towards the outlet tube which is present in the bottom of the water reservoir. The pressure from a reservoir pushes the water towards the solar panel and it gets heated up. It continues to heat water as long as solar energy is present.

Both types of solar heaters are eligible to provide you hot water during the day time and works very effectively. The water which is present in the tank also retains its heat at night as well.  A person can even have a gas heater as a backup in case hot water is needed at late night or early morning. Therefore solar water heaters are very useful for a person and very easy to get hot water free of cost and without any kind of pollution in the environment.
