Choosing the Best Solar Pool Heater -Buying Guide

1. Type of Pool

There are different types of swimming pools and thus require different types of floating pool heaters. The major types are in-ground and above-ground water pools, and their requirements are different. Because of this difference, not all floating heaters are compatible with both designs.

Some options are best for an in-ground pool, while others are best for above-ground, while some can function with both types of heaters.

However, in-ground pool heaters are quite pricy and require a permanent connection because they will be connected to the pump and filtration system. Normally they allow water to pass through them and then into the pool through their XL 2 inches opening.

2. Temperature

Pool temperature levels differ from person to person. Knowing what temperatures keep your pool warm is key as it will guide you when choosing the best floating pool heater.

Different pool heaters offer different water temperature levels as they all use sun energy—some warm water up to 10 degrees Fahrenheit while others heat up to 5 degrees Fahrenheit. Once you have an idea of the ideal water temperature and considering your pool type, you can choose the best fit.

Also, some floating solar heating systems are stronger than others and may be used in different swimming seasons as long as solar energy is available.

You will need a lot of consideration before settling for the best water heater.

3. Pool Size

The size and shape of the pool are the first determinants of what floating pool heater you will need. Some floating best solar pool heaters work well with small-sized pools, while others work well with big sizes only. Although few are adjustable, make sure their compatibility is stated on the user manual.

Again, the capacity of your swimming pool should act as a guide on the size of your pool heater. Ideally, the higher the capacity, the more energy will be required to heat your swimming pool. To get the correct size, multiply the depth by width by the length. You’ll get the total cubic meters, which you will then multiply by 7.48 to get the number of gallons it can hold.

That’s a simple calculation for a rectangular pool, which is just an estimate. Otherwise, a different algorithm is used to get the number of gallons it can hold for a round or irregular-shaped pool. This cubic area will help estimate the amount of energy required to heat the entire pool and the number of hours you will need.

4.  Ease of Installation

Before building a pool, several things are put into consideration, including heating system installation. Whether you will need a DIY or hire a professional depends on the type of heater you will choose.

Some heaters work with your existing system, while others need special installation to work independently. Consider the available options carefully as you decide one over the other. There are three different types of solar heaters you can choose from, including the floating types that require no installation and are simple to use and maintain water temperature for longer.

There are also dome-shaped heaters that need some level of professional installation to work alongside your existing pump and filters.

Panels require expert installation on the roof because of drop-down connecting valves, pump, heater, and filter. Some pools require more than one piece of solar panels, and therefore, the need for expert installation is required to ensure warm water availability.

5. Ease of Use

One of the greatest advantages of solar water heaters is their ease of use. While setting up might be difficult, you will only need regular checkups at the pump and the filter to ensure water flow.

You will not need to own any gas or electricity heater as with a solar heater; your pool heating need is sorted. It gives you efficient energy all year round and without other further connections. It’s also easy to use, produces clean energy, and requires little or no maintenance.

With a floating water heater, you only need to place them in water when you want to heat, and you are good to go.

6. Pool Covers Material

The best floating solar pool heater is made of heavy-duty vinyl with sheet foam to help in floating. The material allows it to trap sunlight energy and retain it even at night through its insulating layer.

After long exposure to sunlight, the vinyl floats break and become chipped. But products with a double vinyl layer, with UV-resistant properties and PVC-customized, last longer and do not chip or break.

7. Maintenance Cost

Before buying any system that operates through renewable energy, maintenance thoughts cross your mind before you settle. Floating pool heaters are no exception. Before deciding which one serves you best, factor in maintenance cost, including repair in case of tear and wear.

Maintenance cost will solely depend on the type of heater you settle for. For large-size heaters, the system is big hence increased maintenance compared to the swimming pool solar heater of a small pool.

One great advantage of solar heaters is that they are eco-friendly and require less or no maintenance. The system relies on sun rays to operate independently.

To keep them running for long, you‘ll need regular cleaning of the pump and the filters to avoid blockage. Floating water heater and dome are the best recommended as they require minimal

maintenance and repair, yet they function efficiently.

8. Cost

After all other considerations in a solar pool heater, the price comes last because it a huge factor in determining what heater you will settle for. Having a clear budget before comparing other features can give you the best guidelines to settle for what you can afford.

Best solar pool heaters differ in price the same way they differ in features. However, functionality features may be considered more; buying what you within your budget will give you satisfaction.

Again water heater prices vary depending on the size of the pool, type of pool, maintenance costs. Research before buying and factor in other costs that may come after buying.

9. Warranty

A warranty guarantees quality to some products like floating solar heaters and solar panels. When buying, you need to be sure that the solar will serve your needs without interruptions. Although all the heaters that we have highlighted here are long-lasting, you still need assurance that a defect comes up along the way, and the warranty here will cover you.

Some warranties have limited months or years, and if anything happens thereafter, you cannot claim repair or compensation from the seller/manufacturer. When buying the best solar pool heaters, consider the warranty term and to what extent you are covered.

Companies that give long and detailed warranties portray a guarantee of quality, thus offering long-term assurance and protection to their customers.

 Frequently Asked Questions (FAQs)

1. What is the best solar heating system for pools?

A. The best solar heating system for pools depends on different considerations. The size of the pool, type, price, maintenance, the temperature required, and functionality are some of the major factors you look into before buying.

The best solar heating system is one that is easy to install and use. Floating solar pool heaters and dome match this description, although temperatures differ from large heaters like solar panels.

On maintenance, floating pool heaters are the best. They require minimal or no maintenance cost, yet they last long. The only maintenance required is regular cleaning of the filters and pump to remove debris that causes clogging.

So the best solar heating system is one that meets all your requirements without stretching your budget too far.

2. Are Solar Pool Heaters any Good?

A. Yes, they are good. Solar pool heaters are definitely good for warming up your pool. Many users

have confirmed that their usage has made swimming more comfortable even in cold weather, although they best produce more energy in warm weather since they depend on sunlight to perform.

Solar pool heaters are also ideal because they are environment friendly, easy to use and store and have a wide variety to choose from. Different solar pool heaters produce different temperatures. Depending on the size and type of your pool, choose a water heater that matches the temperature you desire.

3. Do Solar Sun Rings Work Pool?

A. Yes, they work. They have a magnet that holds them together to help in retaining energy from the sun. The magnets also reduce water toughness, and the disks can tap solar energy and direct to the water and raise the temperature.

Solar rings are designed as floating water heaters with high-quality material and designed in different size packs for your convenience. They can be used on any above-ground pool to ensure effective heating due to their curved shape covering the whole water surface.

Again they are double layered with UV-resistant vinyl meaning they will not require an extra tool to perform and will serve you for years without chipping or breaking. However, the color will change with time due to too much exposure.

Sun rings are also easy to install and durable. They offer a long-term service with less trouble as they only need sunlight to keep your pool heated for a long time.

4. What is the Most Efficient Way to Heat a Swimming Pool?

A. A pool can be heated in different ways to raise the temperature to your preference. You can use gas, electricity and solar pool heaters although the latter is the best as they are environment friendly. To heat your pool efficiently, use a water heater that best suits your pool size and type.

A floating pool heater may not be efficient in heating a huge pool but will perfectly heat a small swimming pool. Pool heating efficiency also depends on the amount of temperature the heater can produce over a given period. Some water heaters are slow but effective over time.

Another way you can ensure efficient heating is by positioning your heater directly to the sun to help absorb maximum energy, which is later transferred to the water pool. Some pool heaters need sunlight at specific times of the day and tilted at a particular angle; otherwise, they will not tap any heat.

Floating heaters require a connection to the existing water pump and filtration system to perform efficiently. In case the connection is loosened up, the pool will not be heated.

5. How Much Does it Cost to Install a Solar Pool Heater?

A. The cost of installing a solar pool heater depends on the type of pool and the type of heater. There are two major types of pools; In-ground and above-ground pools. They determine what type of heater installation you will require.

In-ground swimming pools have several options for solar pool heater installation, while the above-ground have limited choices. Best floating pool heaters are the easiest to install as they don’t require any professional to connect.

However, solar panels have more power thus require professional intervention as they need several down connections to the pool before they start working. The panel is best placed at the roof for an easier down-connection. However, how much you will spend also depend on the complexity of the system. E.g., for solar pool flower, you only need to place them on the pool, and you are good to swim, compared to game solar pro contour, that requires a fixing process.

6. What Size is Best for a Pool Heater?

A. There is no one size fits all theory in solar pool heating. The best solar pool heater size depends on the size of your pool, the type of your pool, the temperature you need, and of course, your budget.

Some pools require more than one floating water heater to get maximum heating, while the same can work with one dome pool heater or solar panels.

Water heaters also have different sizes for different functioning. Some are small, easy to use but take too long to get water warmed up, while other similar sizes have more power thus heat up very fast.

To choose the best size for your pool, consider you pool orientation and the surrounding. Better still, you can consult the experts before buying to give you the best idea of the heater that will work best for you.


Solar pool heaters are an excellent choice. They are environment-friendly, easy to use, cost-efficient, and last longer than gas.

Further, different types of solar pool heaters range from floating type, dome, and solar panels. Their installation, however, differs from the solar panels that require an expert. Some like floating solar-type use existing pumps and filters, while others require extra tools to heat swimming pools.

Once your solar water heater is set up, you will enjoy warm pool water without a fuss. To determine what best suits your pool, consider its size, budget, temperature level, pool type, and maintenance cost.
