There are a few factors you need to consider when choosing a solar pool heater.
Solar pool heaters are used in order to extend the swimming season to basically all year round instead of just warm summers and seasons. Choosing solar pool heaters will require you to have some technical knowledge of your situation – and some research won’t be bad either. Remember, solar pool heaters depend on your area which means that one part of the country’s best solar pool heater may not necessarily operate efficiently in your part.
Factors to Consider
In order to discern which type of solar pool heater is the best for you, you must consider these things:
There are generally two types of solar pool heating systems: the passive and the active. Passive systems allow the water to circulate through the collector panel. This panel is where the water is heated. It is then passed into the pool while fresh water enters the collector and so on. In active systems, the water goes through the collector where it is heated and then pumped into an insulated tank and, in solar electric systems, the water is heated electrically.
For optimum efficiency, solar pool heaters should have a collector panel which has the surface area that is equal to or at least half of the size of the surface of your pool. If your area is cloudy or if the climate is a little cooler, increasing the ratio will help you balance this out. Remember, the larger the solar collector’s surface area in relation to the pool size, the warmer the water can potentially be and the more warmth is generated by the system.
You can find out the thermal performance rating of the collector panels from your supplier. The rating is presented and measured either in British thermal units per square foot per day or in mega joules per meter per day. Basically, the higher the Btu or MJs collected, the more efficient the collector is.
The cost does not only cover the initial cost but also the long term operational costs. Investing in a more expensive system that requires a lesser number of collector panels may actually save you more money in the long run.
Installation requirements should also be considered when choosing solar pool heaters. For instance, some collectors are required to face the direction of the day’s greatest sunlight when installed. Some panels require positioning at an angle that is between 15 and 45 degrees facing the sun, without hindrance or shadows from trees or buildings and other structures. Identify the best location to place the solar pool heaters to install them correctly.
