How does a Solar Pool Heater work?

A Solar Pool Heater harnesses the natural heat from the sun, making it a cost-effective and environmentally friendly way to warm your pool water. Here's how it works:

 

  1. Sun's Free Heat: Solar Pool Heaters utilize the sun's energy without any operating costs. This renewable energy source is abundant and readily available.

  2. Circulation System: Your existing pool pump circulates the water through the solar heater, typically installed on the roof or another sunny location. As the water passes through the solar panels, it absorbs heat from the sun-warmed panels

  3. Operation During Sunlight Hours: The pump timer is programmed to operate during sunlight hours, usually from 9 am to 5 pm, when solar radiation is strongest. This ensures maximum efficiency in heating the pool water.

  4. Automatic Controls: In some cases, an Automatic Control and Valve are installed to regulate the temperature. This is particularly common in northern climates where maintaining a consistent pool temperature can be challenging.

  5. Booster Pump: Larger residential pools or commercial pools may require a booster pump to ensure adequate water circulation through the solar panels, optimizing heat transfer.

 

By utilizing solar energy, Solar Pool Heaters not only reduce operating costs but also minimize environmental impact compared to traditional heating methods. They extend your swimming season by maintaining comfortable water temperatures, allowing you to enjoy your pool for longer periods throughout the year.

Types of Solar Pool Collectors:
 

Solar pool collectors come in two main types: unglazed and glazed, each suited to different climates and usage scenarios.

 

1. Unglazed Solar Pool Collectors:

Unglazed collectors are ideal for pools that are used primarily when temperatures are above freezing. They are constructed from heavy-duty materials like rubber or plastic treated with UV inhibitors to enhance durability and extend panel life. These collectors do not have a glass covering (glazing), which makes them more affordable compared to glazed systems. Their simple design and lower cost make unglazed collectors a cost-effective choice for many pool owners.

Advantages:

  • Cost-effective: Lower initial investment and maintenance costs.

  • Durable: Designed to withstand various weather conditions.

  • Suitable for various pool types: Can be used for in-ground, above-ground, and indoor pools.

Considerations:

  • Limited insulation: Unglazed collectors may lose heat more quickly during windy or cooler weather due to their open design

 

Freeze Protection: It's essential for unglazed collectors used in colder climates to include freeze protection mechanisms to prevent damage during freezing temperatures.

What size solar pool heater system do I need for my pool?

 

Generally you will need a system equal to 50 to 100% of the pool surface. Solar panels are available in 4x8, 4x10, 4x12 and custom sizes. They are generally placed in a row on one or several roofs.  A typical 7 4x12 panel system would require a space of 12.5 ft by 30.75 ft. 

 

To determine the size required for your pool, use the Automated System Sizing Calculator

 

Each pool & home is unique.  The size of the heater is based on several factors, including:  the size & shape of the pool; pool shading (i.e. trees, screen enclosure); geographic location; swimming season and pool temperature desired; windy conditions; and direction of the roof (south, east, west or flat). The size of the heater will determine the temperature, swimming season, and length of time to heat the pool. It is very important to properly size the heater for good performance.

 

Keep in mind that a Thermal Pool Cover is recommended for all heating systems. Heating a pool without a cover is like heating a house without a roof...the heat just goes right out the top. Without a pool cover, the cost of operating a Heat Pump or Gas Heater is doubled, and a Solar Heater's effectiveness is dramatically decreased.  For convenience a roller may be added to ease placement and removal of the cover.  If a pool cover is not be used, the size of the heater must be increased by 75% - 100%. Pool covers range in cost from $60 to $130 for residential pools; rollers start at $185.

Energy Rating and Efficiency

Solar pool panels are rated by FSEC (Florida Solar Energy Center) in BTU's per Sq. Ft. The higher the BTU, the more heat output. The average output is 900 to 1000 BTU's. This equates to a 3 to 7% difference between different brands. To determine the best value, divide the total cost by the total Sq. Ft. of panel. The lower the cost per Sq. Ft., the better the value.

 


Longevity and Maintenance

A quality Solar Heater will typically last 10 to 20 years. They are very low maintenance. Most systems have a 10 year warranty on the panels.

 

 

Brand Comparison

When comparing solar pool collectors, it's important to focus on specific factors rather than just BTU ratings, as they perform similarly in heating pools of the same size when installed in equal numbers:

 

  1. Weight or Material Content: Our collector panels are designed to be 25-40% heavier than the industry average. This extra weight enhances durability and extends their lifespan significantly.

  2. Connection Method: The method used to connect headers or manifolds to the absorber board is crucial. Sonic welding and our unique patented process, as used in the Vortex panel, are among the most effective. These methods ensure strong, reliable connections compared to less effective methods like thermal welding or injection molding.

  3. Warranty Type: Consider whether the warranty covers replacement or repair of defective panels. Many warranties allow for repair at the discretion of the dealer or manufacturer, potentially reducing panel efficiency over time. At Pool Heating Distributors, we provide a full 10-year replacement warranty for all defective panels, ensuring optimal performance throughout the warranty period.


By focusing on these factors, you can make a more informed decision when selecting solar pool collectors, ensuring they meet your durability, reliability, and warranty expectations.
