Pool Size

The bigger the pool size, the larger the pool heater should be. But this might not always be the case since technology has helped create efficient little machines as well. Regardless of the size, you should definitely check the amount of water the heater can heat and how many degrees it can heat the water till. Since both the factors require considering the size of the pool, you should always buy within the capacity of the heater.

How Solar Pool Heaters Work

Solar pool heaters mostly include the following three components, a solar collector or solar panels, a filter and a pump. Firstly, the water in the pool is filtered and sent to the solar collectors. These solar collectors are attached to solar panels which use the heat from the sun to warm up the water.

Most systems have either an automatic or manual valve that diverts the water into the collector’s tube when the temperature of the tube is higher than the temperature of the pool’s water. This flow of heating the water continues unless the system is turned off or the automatically censored valves detect that the collector’s tube temperature is much less than the temperature of the pool.

Things To Consider While Installing The Solar Pool Heaters

Collectors can be mounted on roofs, ground, fences and other areas with a slight inclination. But with everything else in technology, there are many aspects that you should consider before installing something because there is always a way to get the most out of something. So here are things that you should consider before installing the collectors of your solar water heating system.

The Area

The roof is typically the best place to install the collectors because it has more exposure to the sun, compared to the ground. But if you have a large number of solar panels then you should also consider the space of the area you are installing the collectors in.

The Tilt

The collectors should be installed at such a tilt that it maximizes the exposure to the sun all year round or to a particular season. If you use your pool only during the summers then you should install the collector at an inclination of your latitude minus 10 to 15 degrees. But if you live in a place that has year round pool weather then the collectors should be installed at a tilt equal to your latitude.
