Putting up pool heaters that use solar energy is a great way to reduce the price of keeping your pool warm. Systems such as solar pool heaters have relatively low yearly running expenses and are priced similarly to gas and heat pump pool heaters. Several materials may be used to construct solar pool collectors. The climate where you live and the intended usage of the collector will determine which one is best. A glazed collector system may be unnecessary if you want to use your pool only when the temperature is above freezing. 

Collectibles without a glass dome are called “unglazed” (glazing). They are often constructed from robust rubber or plastic treated with a UV light inhibitor to make them endure longer. Unglazed collectors are often less costly than glazed collectors because they employ cheaper materials and have a more straightforward design. Even in colder areas, these unglazed systems may be used for indoor pools, provided they are built to drain back into the pool when it is empty. Though you’ll have to turn it off in cold weather, using unglazed collectors might save you money compared to a glazed collector system.

The cost of glazed collector systems is higher because they typically consist of copper tubing on an aluminium plate covered by iron-tempered glass. Glazed collector systems are superior to unglazed systems in colder climates for capturing solar heat. In many areas, this means they can be used all year round. Glazed collectors may also be used to heat residential hot water for use throughout the year. If the collector system will be utilised in colder circumstances, it has to have some freeze protection, whether it has glass or not.

How To Select The Best Solar Swimming Pool Heater?

The typical cost to build a solar pool heating system is between $2,500 and $4,000. Based on the cost of fuel in your area and the amount of sunlight available, the payback time for this system is anything from one to seven years. Their longevity also exceeds that of gas and heat pump pool heaters. Many variables will affect the final price and return you see. As a result, you should undertake the following things before buying and installing a solar pool heating system:

  • Consider the solar potential of your location.
  • Find the ideal size for your system.
  • Identify the optimal collector orientation and tilt.
  • Find out how effective the system is
  • Evaluate the prices of various systems
  • Find out about the laws, covenants, and rules in your area.

Consider The Solar Resource At Your Location Before Purchasing And Installing A System 

If you’re planning on heating your pool using solar energy, you should first evaluate the solar potential at your location. How much sunlight enters your construction site affects the effectiveness and layout of your solar pool heater.

Depending on the design, solar pool heating may take advantage of either direct or diffuse sunlight. You may have sufficient solar resources at your location even if you don’t reside in a region with mild weather year-round. Your construction site is ideal for a solar pool heating system if it has enough unobstructed, south-facing exposure and no trees or other obstructions to block the sun. A local solar system provider or installation may perform a solar site study.


Numerous considerations go into a successful solar pool heaters installation. Solar resources, climate, local construction code restrictions, and safety concerns are only a few. It is recommended that a professional solar thermal systems installer be hired to set up your system.
