Nowadays people are going for using the solar pool heating systems to reduce the cost spend for the pool heaters. The solar pool heaters are having a very low annual operating cost and most of them are a cost-effective use of solar energy in many climates.
But still, now some people are confused with the working process of pool solar heating system. If you want to know about the working process of solar pool heating system, before that you want to know the basic parts of solar pool heaters which are listed below,
A solar energy collector:
This is a device through which the pool water is circulated to be heated by the sunlight.
This part helps to remove all debris from the pool before water is pumped through the collector.
This part helps to circulate the water via the filter and collector and push the water back to the pool.
A flow control valve:
This may an automatic or manual operating device which diverts pool water via the solar collector.
Working process of the solar pool heating system:
The solar pool collectors are made from different materials and the type of the pool heaters you will need on your home is depends on your environmental climate and how to intend to use the collector. If you will only be using your pool when the temperatures are above the freezing point then you will probably only need an unglazed collector system.
The unglazed collectors don’t include a glass covering or glazing. They are generally made of heavy-duty rubber or plastic treated with an ultraviolet light inhibitor to extend the life of the solar panel. Because of their inexpensive parts and simple design unglazed collectors are normally less expensive than the glazed collectors.
These unglazed systems can usually less expensive than the indoor pool in cold climates if the systems can even work for the indoor pools in a cold climate if your system is designed to drain back to the pool when it was not in use.
For example, if you have shut down the system during the cold weather, the unglazed collectors may be more cost-effective than installing more expensive glazed collector systems. The glazed collector systems are normally made of copper tubing on an aluminum plate with an iron-tempered glass covering which increases their cost.
In a colder weather glazed collector systems with heat exchangers and transfer, fluids capture the solar heat more efficiently than unglazed systems. Hence they can be used year-round in many climates. The glazed collectors also can be used to heat the domestic hot on whole year. Both glazed and unglazed collector system should include the freeze protection if they will be used in colder conditions.
As a conclusion of this article, the working process of solar pool heaters is only based on the solar power. Hence there is no need to apply any other external power supply to heat your pool.
