The actual amount of savings one can get by using the best solar pool heaters depends on the climate of the region. In areas that receive plenty of sunshine, such as Florida, Colorado, Arizona, California, and Georgia, the savings on water heating bill can range from 70% to 90%.

Also, solar heaters have become more affordable over the years. The cost of installing an in-ground solar pool heater starts at under $2,000, while an above ground solar pool heater costs nearly half that amount. So, price is no longer an excuse when it comes to installing swimming pool solar panels to heat the water.

How do Solar Pool Heaters Work?

As the name suggest solar water heating (SWH) occurs when sunlight is converted to energy or in the case of water it is converted to heat, with a device called a solar thermal collector.

Solar water heating systems consist of solar panels and a collector that use sunlight to heat pool water. Most solar pool heaters include four basic parts:

1. Solar collector(s)
2. A pump
3. A filter
4. A control valve

source

Pool water is pumped to the solar collector through a filter that removes debris. Solar collectors can also absorb sunlight directly. Once the water has been heated using the sun’s energy, it is pumped back to the pool. Some collectors also combine a working fluid into the mix that consists of a gas or liquid to aid the heating process.

An automatic or manual flow control valve and sensors divert water towards the collector when the collector(s) temperature is higher than the pool. If the collector(s) temperature is similar to the pool, water is simply filtered, and it bypasses the collector before being pumped back to the pool. During peak summer months, the collector(s) can also be used to cool the pool water at night.

The diffused radiation feature allows the system to heat water even on cloudy days. For solar pool heating system connected to a gas and electric heater, a backup heating system can be switched on if the water is not sufficiently hot during cloudy or foggy water. The combination of solar and traditional heating system will ensure that the pool water remains warm on any given day while the energy cost remains minimal.

Types of Solar Powered Heaters

Solar powered heaters come in different size and varieties. The type of solar power pool heater one should choose depends on the pool size, as well as the climate of the area.

Pool heaters with glazed solar collector systems are generally ideal for outdoor pools in colder climates as they are able to capture heat most efficiently. The collector is made of iron tempered glass covering and copper tubing on an aluminum plate, which make them more energy efficient. However, the expensive glass covering may increase the cost to some extent.

Example of a glazed solar collector

Water heaters with unglazed solar collectors are less efficient in capturing energy. However, these systems are generally cheaper than the glazed solar collectors since they do not include expensive glass covering.

They are made of UV-resistant plastic or rubber construction and are ideal for warm and sunny climate zones. With that said, these collectors may also be suitable for indoor pools in colder regions if the solar heater is fitted with a sensor that drains water back to the pool when not in use.

Advantages of Using A Solar Pool Heater

Installing solar pool heater will provide a number of benefits. Some of the advantages of installing a solar heater for your pool are as follows.

• A Solar pool heater will help reduce carbon footprint as it utilizes clean and free energy coming from a natural source.
• Installing solar pool heater will reduce your energy bills. Apart from the initial costs of purchasing a solar heater, the monthly cost of operation will be much lower.
• As compared to traditional pool heaters, solar pool heater requires minimum maintenance.
• A solar pool heater comes with an extra long warranty period. Typical warranty of solar pool heater runs from four to five years.
• Solar water heater work together with existing heating systems, thereby ensuring that the water remains warm all year round.

You can save a lot of money by installing a solar pool heater. In order to determine the exact savings that will result from solar water heater installation, you must follow these three simple steps:

Step 1: Find out energy requirement for heating the pool using traditional electric, gas, or oil heater in an hour. You should determine electricity wattage consumption, cubic meters of natural gas, or liters of propane oil that is required to heat the pool in one hour.

Step 2: Now, multiply the energy usage for heating the pool determined in step one with per unit cost of energy. This will give you the hourly cost of using the conventional pool water heater.

Step 3: Next, multiply the hourly cost of heating the pool determined in step two with the number of hours the pool is in operation during a year. This will give you the yearly cost of using a conventional pool water heater.

Step 4: You must now determine the number of hours solar power heater will be used round the year. Multiply this number with the hourly cost of using the traditional water heater as determined in step two.  The resulting figure will be total amount of money saved using the pool water heater in one year.

Step 5: Lastly, subtract the hourly cost of using the solar heater determined in step four from the hourly cost of using the traditional pool determined in step three. This will give you the total amount of money that can be saved with a solar water heater.

Factors that Can Increase The Efficiency of a Solar Pool Heater

The actual increase in temperature of the pool water depends on various factors. Obviously, the main factor is the size of the solar collector. However, there are other factors that play a key role in determining the heat generation efficiency of the solar heater.

Orientation of the solar heater affects efficiency of the system. For optimal results, the water heater collector should be oriented to the north. The next best results can be obtained when the solar panels are oriented to the west.

Tilt of the solar collectors also affects solar pool heater efficiency. For maximum effectiveness, the solar heater should be tilted at an angle equal to geographical latitude, plus 10 to 15 degrees. However, the existing pitch of the roof will limit they way you can position the solar collectors.

Another surprising fact regarding solar heaters is that the roof construction can also affect efficiency. Collector panel placed on metal roofs conduct heat more efficiently as compared to those placed on tiled roofs.

Color of the collectors will also affect efficiency of the heaters. Black color heaters are the most efficient in trapping sunlight for heating the water. Using a light colored panel will result in decreased efficiency in collecting the heat, but the difference will not be too significant.

Another thing to note about solar power heaters is that direct shading over the collector will negatively affect their efficiency. In such a case, you need to install additional collectors to counterbalance the affect caused by shading.

In addition, windy areas generally result in rapidly more rapid loss of heat as compared to areas where the wind is still. You should use additional collectors if your pool is located in a windy area. You can also consider using solar pool covers, blankets, or rings to reduce heat loss and evaporation rate.

Installing a Solar Pool Heater

Solar pool heaters typically cost around $2,000 to $4,000 to install and buy. Due to the savings in energy bills, you can easily recoup this investment in about two to seven years, depending on the fuel costs and the area where you live. They require almost no maintenance and usually last for a much longer time as compared to traditional pool heaters.

Before you purchase a solar heater for your swimming pool, there are certain things that you should do to ensure that you select the best solar heater for pool. These include:

• Determine solar resources in the area where pool is located.
• Research about the size and type of heater that is best suited for the pool.
• Determine the efficiency and costs of different solar pool heaters.
• Find out about local codes, regulations, and conventions.

The annual sunshine duration or how much sunshine reaches the site where the pool is installed will determine the size and type of pool heater you should buy. Generally, solar heating systems use two kinds of energy sources.

• Direct sunlight
• Diffuse solar radiation

Both of the above energy sources are utilized to provide heat to the pool water. This means that even if the pool is located in areas with less sunshine such as the southwestern states in the US, it can still heat the water. The only requirement is that the solar panel should be located in an area without a shade.

Your solar system supplier can evaluate the site’s solar resources and recommend the best solar pool heater for you. They make use of computer programs and worksheets to size up the area and determine solar heater collector sizing and system requirements.

Usually the size of the solar collector should be about 50% to 100% of the pool surface area. Larger sized solar heaters are needed for cooler and cloudier areas.

For instance, a solar panel collector with a size equal to 100% of the square footage of the pool is required for colder region with less sunshine. On the contrary, areas that receive lots of sunshine such as Arizona or California, a system with an area of 60% to 70% of the surface area of the pool is sufficient.

You must also determine size of the pump that will be adequate for properly heating the pool. If you want to completely replace your conventional pool heating system with a solar powered one, you should buy a larger pump to transfer the pool’s water through the circulators.

You may also consider buying a separate smaller size pump to adequately transfer pool water and keep it at a desired temperature. In addition, you can greatly decrease the required size of the collector by buying a solar pool cover, blanket, or solar rings for your swimming pool. Also, a solar cover reel is recommended to easily put on and off the cover.

When installing a solar water heater on the roof of the house, you should make sure to follow local building regulations and code. There should be enough room on the roof to allow maintenance checks. Consider getting the site inspected by a professional to ensure that the installation is compliant with the code of your local building authority.

Maintenance

The costs of maintaining a solar power heating system is very low. As mentioned previously, a solar water heater usually comes with a warranty of five years and more. After the solar water heater is installed, you won’t incur any additional costs.

That said, you should consider having the solar pool heater checked by a professional every three to five years. This is necessary to ensure that the anti-freeze feature of a solar pool heater is in perfect order and whether it requires topping up or even replacement in case of leaks.  Note, that it will cost you around $100 to replace the anti-freeze fluid in the solar heater panel.

Anti-freeze liquid is required in regions where the temperature during the winter dips below freezing point. The liquid prevents the water inside the pumps from freezing at night when the temperature is the lowest. It should be changed after every three to five years by a professional technician.

Also, you must have the pump checked to ensure that it is working properly. A well maintained pump can usually last for ten years or more. Replacement cost of the pump can be around $80 to $100.

There are three things that you need to check on an annual basis. You must check the system pressure and make sure that it has not dropped below a specific level. This can simply be done by looking at the pressure gauge of the pool heater.

Another thing that you need to check annually is the controller of the solar panel. Make sure that the controller is working correctly. Ensure that the main system controller shows no error or warning sign.

The third thing that you need to check annually is whether there has been any damage or leaks to the insulation of the pipe that runs to and from the solar panel. You should remember to check the pipes especially after extreme weather to ensure that the pipe of the solar pool heater is in perfect condition.

A solar water heater can be left unused for up to one month without requiring any intervention. You must consult with your supplier to find out what needs to be done if you will be away for extended period of time.

Remember that storing water at 50 to 122 degrees Fahrenheit can promote growth of Legionella bacteria. This can pose a health risk to the individuals. You should consult with your supplier on how to heat stored water up to sufficient temperature to kill the bacteria.

Best Solar Pool Heater and Accessories

Now we will take a look at some of the best solar pool cover, blankets, rings, panels, and other accessories that you must but to benefit from maximum heat gyration and retention benefits. This will result in optimum savings in energy heating expenses that can amount to in thousands.

1. Solar Pool Covers

Solar pool cover prevents heat from escaping. This reduces the frequent requirement to heat the water to maintain at a desired temperature. At the same time, they decrease the rate of chemical evaporation, thereby reducing chemical usage, and saving you money. Also, they prevent debris and leaves from entering the pool thus saving a lot of clean up time.

And that’s not all. Adding solar cover to the pool can save you tons of money in water cost as it will dramatically reduce the rate of evaporation by up to 99%. By using less chemicals, and reducing water and energy usage, you will be able to greatly reduce your carbon footprint on the environment.

The savings from the use of solar pool cover add up to cover the costs in just one season. The following table presents how much you can expect to save in a single season by installing a solar pool cover on a 24’ swimming pool.

Good quality solar pool covers have high heat absorbing properties. Even if it does not cover the entire pool, it can increase temperature of the pool water by a few degrees. When used in combination with a solar pool heater, it can make a noticeable difference, resulting in 15-18 degree increase in temperature. What’s equally important is that the heat will be retained for a long time, and it will require you less time to heat water at the beginning of each day. There are solar pool covers that come with algae blocking capabilities which make them an ideal accessory for any swimming pool. These benefits make solar pool cover an important element of the pool heating system.

Customers that reside in areas with high wind conditions should buy wind weights to ensure that the solar pool cover does not blow off due to high wind. It ensures that the pool remains at its warmest at all times, and conserves energy to reduce the heating time.

Selecting the Best Solar Pool Covers

Solar pool covers are available in different types and sizes. The material and build of the cover determines expected temperature rise and heat retention properties. In addition, there are other factors that affect thermal properties of the solar cover, including ambient night time temperature, climate conditions, shade conditions, cloud cover, average daily direct sunlight hours, pool direction, and pool drain location.

1.     Solar Cover Reels

A solar pool cover makes it easier to install and remove solar pool covers. Reels come in different styles and shapes. There are different cover reels for above ground and inground pools.  In addition, the reels are different for round, oval, and rectangular shaped pools.

Above ground reels are typically mounted permanently onto the rails of the pool at the top. In addition to this, there are some that feature a quick-release or pivoting option that makes it easy to remove when required.

Reels that are designed for inground pools are mounted around the pool on the ground. Similar to the above ground reels, some of them can be mounted permanently on the pool while others feature castors that provide greater mobility.

Selecting the Best Solar Cover Reel

Buying the right reel for the solar pool cover requires a little research as well as knowledge of the pool. There are different types of reels available that are suitable for different pool covers. So, it’s important to make sure that the reel you buy is perfectly suited to your solar pool cover.

Three main things to consider when buying a solar cover reel include solar cover width, thickness, and length.

Generally, thicker solar covers that are used in large commercial swimming pools require high grade solar cover reels that can bear the weight of the covers. Lower grade reels should not be used with thicker solar pool covers.

Another thing to consider when buying solar cover reels is the width of the solar cover. Make sure that the solar cover reel completely fits the pool. A reel that is too narrow will not be usable. On the other hand, a reel that is too large will be ill-fitting and too cumbersome.

Some solar cover reels, however, are adjustable typically through telescoping and segmented tubing and can accommodate any size pool cover.

The last thing to consider when buying a reel is that it should be of suitable length. Longer solar cover reels that exceed the tubing tolerance can break. That’s why it’s important to ensure that the length of the solar cover reel is recommended for the specific solar cover.

2.     Solar Blankets

Solar blankets help in retaining heat thereby allowing the pool to remain warmer for longer periods of time. The blanket appears like a large sheet of bubble wrap. Installing the solar blanket increases the intensity of sun rays falling on the pool. This effectively heats up the pool water quickly and retains heat for longer periods of time.



Bubbles of the solar blankets trap heat and reduce heat loss during the night. Also, a metal reel can be attached to one end of the pool deck that makes it easy to roll the blanket on or off the pool. The solar blanket is not required to be attached to the sides of the pool and floats freely on the surface.

How do Solar Blankets Retain Heat?

Solar blankets are made up of a large number of bubbles. The tiny bubbles work together to retain heat in the pool. The blanket floats on top of the pool water and traps some of the heat from the sun. Installing the blanket on the pool can result in 10 to 15 degrees increase in temperature at the most, which extends the swimming sessions.

You can think of solar blankets as insulators. They are made of thick polyethylene foam that is waterproof. The thermal blanket completely blocks UV rays from penetrating the pool that may encourage algae growth. Underside of the blanket is resistant to chemicals present in the pool water.

Using the solar blanket can reduce the need for frequent heating of the pool water. This decreases pool water heating costs by up to 75%. In addition, solar blanket can reduce evaporation by about 95%. This effectively results in cost savings resulting from reduced chemical usage. Other than that, solar blankets act as a barrier that prevents debris from falling in the pool water, thereby reducing the need of frequent pool cleaning and maintenance.

Note that since solar blankets are reasonably heavy, you may need a high quality roller to cover the pool area. As mentioned in the previous section, reels come in different sizes and features. You must make sure that the reel you buy for the pool is suitable for the solar blanket.

Difference between Solar Blankets and Solar Covers

Solar blankets are different from solar covers in many ways. They are generally more expensive than solar pool covers but possess greater heat retention abilities. A high quality solar blanket can retain up to 60 to 75% of the heat, while solar covers have reduced heat retention capabilities. This translates into more cost savings.

Another way solar blankets are different than solar covers is that they require professional installation and fitting. The upside of using solar blanket, however, is that they last for a longer time as compared to the solar covers. A high quality solar blanket can last for up to 10 years and even longer.

3.     Circulator

Installing a circulator can save you $500 or more on energy bill each year. It pushes heated water to the bottom of the pool due to which the water remains warm for longer periods of time. The circulator acts as a passive solar heated pool which results in great cost savings.

In a standard pool, the heated water rises to the surface from where it is evaporated. As a result of evaporation, water needs to be heated frequently that increases your energy bill. A standard pool requires its pool pump to run about 8 hours a day. With a circulator, you need to run the pump for a third of that time. The water can be heated faster resulting in big cost savings.

In addition to this, poor circulation of water results in chemical imbalances. A circulator ensures efficient circulation of pool water that enhances efficiency of the chemicals. As a result, the pool will require less chemicals, resulting in cost savings.

Solar rings are easy to store and manage. Some solar rings have eyelets that allow you to hang them up when not in use. Just make sure that you do not store them in the range of direct sunlight as they can be prone to overheating resulting in accelerated wear and tear.

How to Install Solar Pool Rings

Solar pool rings can be assembled easily without any problem. The first thing that you need to do after purchasing the rings is to unpack them and lay them under the sun for about half an hour. They are usually packed tightly in boxes. As a result, when you unpack them you may see some lines on the rings.

After you have unpacked the rings, you must then start inflating them. There is no need to fully inflate the rings. You just need to ensure that there is enough air that holds shape of the ring. This can be easily achieved with four or five breaths.

Once the outer rings are inflated, you need to move to the inner rings. The inner rings need to be inflated lightly as compared to the outer rings. About two breaths will be enough to inflate the inner rings.

Examine the rings to ensure that the air is evenly distributed inside the rings. Once you are done inflating the rings, you must scrunch them together tightly. This will result in even distribution of air within the rings. You can let out excess air in the rings through the deflation tube.

Remember that the blue side of the solar ring must face down when you want to heat up the pool. To cool down the pool, you can turn the rings over. The rings will attach to each other while floating around.

You should remember to clean the solar rings with mild soap. However, avoid washing them with abrasive materials. Also, do not walk on the rings. With proper care and cleaning, these rings can last for more than 5 year.
