You can significantly reduce heating costs by installing a solar pool heater pool. They are inexpensive in competition with the gas and heat pump pool heaters, and they have very low annual operating costs. In fact, solar pool heating is the cost-effective use of solar energy in many climates.
How They Work
The most solar pool heaters include the following:
A Solar Panel - passed to it by the pool water, to be warmed by the Sun
A filter - removes dirt before the water is pumped through the collector
A pump - circulates water through the filter and collector and back into the pool
A flow control valve - automatic or manual device, the water in the pool draws through the solar collector.
Pool water through the filter and then through the solar panel (s), where it is heated before it is returned to the pool is pumped. In hot climates can the collector (s) also be used are around the pool during the peak summer months cooling by circulation of water through the collector (s) at night.
Some systems include sensors and an automatic or manual valve to divert water through the collector (s), when the collector temperature sufficiently larger than the pool temperature. If the collector temperature similar to the pool temperature, filtered water simply bypasses the collector (s) and is back in the pool.
Solar pool collectors are made out of different materials. The type you'll need depends on your 
climate and how you intend to use the collector. If you'll only be using Their pool, when the temperatures above freezing, then you will probably need only an unglazed collector system. Unglazed collector not a glass cover (glazing). They are generally heavy rubber or plastic with a Ultraviolett-(UV-) light inhibitor, to the lifetime of the panels cover stained. Due to their cheap parts and simply built open-air collectors, generally less expensive than glazed collectors. These unglazed systems can work so for baths in cold climates if the system for the disposal of back to the pool, if it is not in use. Even if you shut down the system in cold weather have open-air collectors can be more cost-effective than installing a more expensive glazed collector system.
Example of how a solar panel works.
Case are generally from copper pipe on an aluminum plate with tempered to iron glass glazed collector, which increases their cost made. In colder weather, glazed collector area systems with heat exchangers and Kälteträger capture solar heat more efficiently than unglazed. Therefore they can be used all year round in many climate zones are. Glazed collectors can also be used to warm water heated all year round.
Both glazed and unglazed collector should antifreeze when it will be used in colder conditions.
