FAQs: Solar Pool Systems


Some common questions to help you guide you.

A solar pool heating system uses your pool’s existing filter pump to circulate water through the system. A diverter valve diverts the water so that it flows through the many small passages of the solar collector where it is warmed by the sun. This warm water then flows back to the pool until the pool has reached your desired temperature.

Yes. Simply set your spa circulation cycle at the end of the day and set the thermostat for 104 degrees.

Gas heaters pollute the air directly with carbon dioxide and other emissions. Heat pumps pollute indirectly as a result of pollution released during electricity production. In contrast, solar requires no fossil fuels. It is a clean, abundant energy source that will never contribute to pollution or the depletion of natural resources.

Under normal circumstances, no special maintenance is required during the swimming season. Our quality electronic controls allow you to "set and forget" the solar heater. It is recommended, however, that you shut off and drain collectors during the winter. This process takes just a few minutes. See our owner’s manual for a description on how to prepare for winter conditions (e.g., freezing).

The solar collectors should be installed where they can be fully exposed to the sun for a most of the day. Depending on the angle of the mounting surface, east, west and flat facing systems can function equally as well if sized properly for the pool.

The solar collectors are generally mounted on the roof however, the collectors can also be ground mounted or installed on a patio cover.

If you choose a manual system, a diverter valve allows you to turn your solar system on or off. Another option is an automatic heating system, which works like the thermostat you use for home heating & cooling. Simply set the electronic controller to your desired water temperature. If the temperature of pool or spa is lower than desired, the controller turns the motorized valve to allow the pool or spa water to flow through the hot solar collectors. When the pool or spa water reaches the same temperature as the collectors, the controller turns the valve again so the pool or spa water will no longer flow through the system.

With a properly sized solar pool heater, a pool cover is not required to keep the pool at a comfortable temperature during the warm swimming season. However, a pool cover does help retain heat at night and prevent evaporation loss.

There are many factors. The most important factors are the size of your pool and orientation of the solar collectors. Other factors include how long you want to extend your swimming season, the wind across the pool, and whether you use a pool cover. The general rule of thumb is 80% surface area of the pool.

Solar pool heating system prices for a residential pool can range anywhere from $2,500 to $7,000. The location and size of the pool, location of the solar collectors, desired temperature and season, and type of pool equipment determine system size and costs. Because of all the variables, it is impossible to give an accurate estimate without careful inspection of the site.

Since the sun energy is free, there are no operating costs to heat your pool.

Our collectors can be expected to last between 20 to 25 years. Our Solar collectors are covered by a 15 year warranty.
