Pool solar heating systems have many benefits. They are a safe, durable and a considered a cost effective way to heat a pool, while requiring minimal maintenance. With the soaring prices of energy, many pool owners are investing in solar heating for their pool.
Solar pool heaters work in conjunction with your pool's equipment by pumping water through the filter and then through solar energy collectors that warm the water. The warmed water is then transported back into your pool.
Pool solar collectors can be glazed (glass) or unglazed, with the latter being the most popular for seasonal outdoor swimming pools. Most unglazed collectors used for pools are made of durable plastics, rubber or metal tubing. Some solar collectors are mounted on a roof; others can be placed on the ground. Many solar heating options can be installed in existing pools and some boast easy installation.
Solar heat collectors come in a variety of sizes. The size and the number of collectors you should purchase depend on your pool's size, your ideal water temperature and your swimming season's length. It is important that you purchase collectors according to your pool's dimensions.
Solar collectors are also given BTU ratings. Manufacturers will inform you on how many BTUs the collectors yield per square foot per day. The BTU expresses the amount of heat that the collector can output. Essentially the higher the BTU, the more it can heat so one rated at 950 per square foot per day is more efficient for the same dimensions as those with 720.
Most pool solar heater manufacturers insist that they be used with a solar cover. This will better ensure that heat does not escape during cooler times. Solar heating systems are sometimes recommended to be used in conjunction with a heat pump or a conventional heater. This will better ensure that the pool water is being heated even on overcast days.
Ensure you purchase collectors that are suited to your geographical area. They must also be placed in an area that will maximize sun exposure. Many retailers may recommend facing south for this reason. Special considerations and regulations are given to areas that are prone to hurricanes or tornadoes.
Solar collectors that will not freeze, and are rust and UV resistant are available. Some are complete with installation kits for easy set up, although some kits need to be purchased separately. Hiring a trusted professional is always wise in order to avoid potential roofing or filtration system problems.
Also note that some solar heating systems require large pool pumps to carry the water to and from the collectors. This may require you to upgrade your pump or purchase an extra one if it is not sufficient.
Solar systems start at around $1,500.00 and can go into the thousands for more elaborate systems.
