What to Check for When Buying a Solar Heater for An Above-Ground Pool?

You will consider some features when buying anything for your home. And that means checking for specific features when buying a solar heater for your above-ground pool.

The best solar heater for any pool has some must-have features, and they are what to look for to land the best deal. So, you want to check for the features below before spending your money:

The Type of Solar Heater

The first thing you might want to do is check the type of solar heater you want to buy. Solar heaters come in three types, and each one offers advantages that the other types might not have. So, you will have to choose your preferred type:

Flat-Plate Collectors

These solar heaters take the form of solar panels hence the name flat-plate collectors. These solar heaters are the most common in many homes, and they are the majority in our review. You could install them on your roof, but the ground makes an ideal spot. 

Besides, you want to install your solar heater near the above-ground pool for efficient performance. One drawback for this type is flat-plate solar heaters take more space.

But they heat the pool water sufficiently and are worth the investment.

Evacuated Tube Collectors

You want to invest in this type of solar heater for your large above-ground pool. And that’s because these solar heaters generate more heat, ideal for raising the temperature of larger above-ground pools.

These solar collectors use vacuum tubes to help generate more heat. So, consider these solar heaters if you want to keep a larger pool warm and comfortable.

Batch Collectors

These solar heaters could substantially raise your pool temperature to higher levels. These solar heaters comprise a water tank placed inside an insulated box.

Solar energy heats the water in the tank before that water goes back to the pool. As a result, your pool will become hot, probably hotter than you need it to be.

So, you want to opt for a solar heater that works best for you. However, this type is less efficient than the first two.

The Durability of The Solar Heater

You also want to check for durability when sourcing a solar heater for your above-ground pool. You want to check if your preferred solar heater resists UV rays and works efficiently even after exposing it to the outdoor weather for years. 

Although many materials make solar heaters, especially flat-panel collectors, durable polypropylene is one material you want to choose. It is durable and will make your investment long-term.

Therefore, you can check for solar heaters featuring this material or check if your preferred solar heater withstands the UV rays excellently over the years!

The Size of The Solar Heater

Many flat-panel solar heaters measure 2 feet by 20 feet. But some solar heaters are larger. You want to opt for larger solar heaters to collect as much heat from sunlight as possible.

A 4 × 20 feet solar heater collects more heat than a solar heater measuring 2 × 20 feet. So, opt for larger solar heaters if you want better heating performance.

Heating Efficiency

Solar heaters can raise your above-ground pool temperature by 6-10 degrees. A solar heater could take up to 4 days to achieve this result. But a more efficient solar heater takes a short time to achieve the same heating result. 

If you want your pool warm and comfortable fast, you want to buy a solar heater with high heating efficiency.

So, look for solar heaters boasting high heating efficiency to use more of the collected solar heat to raise the temperature.

Solar Cover

Some solar heaters such as Goplus Solar Dome Swimming Pool Heater feature a cover. This cover works to trap heat within the tubes, thus improving the heating efficiency of the pool.

Also, the solar cover keeps dirt and debris out of the intricate internal components of a solar heater.

Since the solar cover is an essential component of dome-shaped solar heaters, you want to ensure your solar heater comes with it.

Installation Process

You also want to check for ease of installation before buying a solar heater. Many solar heaters are easy to install, making them perfect for DIY projects.

But some may require a professional to help with the installation. The good news is many flat-panel collectors are easy to install.

You can place them on your roof or ground, connect them to your pool pump, and leave the rest to your solar heater.

Installing other types, such as batch collectors, will probably require professional assistance. So, check if a solar heater is easy to install before buying it.


How many solar heaters do I need to heat my above-ground pool?

You require 4 to 6 flat-plate solar heaters. But this depends on your area of residence and its temperature. Also, the number of solar heaters you need depends on the size of your above-ground pool.

If you live in a colder area with shorter sunlight exposure, you will need more solar heaters. Also, you will consider adding more than 2 solar heaters if your pool is substantially large. 

What’s the best temperature for my above-ground pool?

You want to ensure your chosen solar heater raises the pool temperatures to the ideal levels. If you expect elderly people to take a plunge into the pool, you want to keep the temperature in the range of 84°F to 94°F.

But if kids frequent your above-ground pool, you want to keep the temperatures between 85°F and 89°F. So, look for a solar heater to achieve and maintain these temperature ranges.

Can I prevent my solar heater from freezing?

First, you want to use PEX piping in place of copper pipes. Second, you could install freeze protection valves to protect your solar heater from adverse cold water and conditions.

Lastly, consider installing a recirculation system. These steps will ensure your solar heater doesn’t suffer a blow if the temperatures outside fall to critical low points.

How long does a solar heater take to achieve an ideal warm in a pool?

It takes a few days, probably 4 days, to have your pool warm and comfortable. Solar heaters don’t rapidly warm above-ground pools (or any pool for that matter).

That means you don’t expect to achieve the ideal warmth after a few hours or a day. Once you’ve connected your solar heater to your above-ground pool, you will wait for a few days to see the results.

Wrap Up

A solar heater ensures your above-ground pool is warm and comfortable even on a chilly day. It warms the pool using free heat from sunlight, thus providing a cost-effective pool heating solution.

Installing them is also hassle-free, all of which makes them an ideal investment for anyone with an above-ground pool.

Besides, even in-ground pools could benefit from these eco-friendly and cost-effective heating solutions. As such, a solar heater is a worthy investment.

Fortunately, finding the best solar heater for your above-ground pool is no longer much of a challenge. And that’s because we have reviewed solar heaters that are among the best units on the market.

We have even included a buyer’s guide with some factors to consider when shopping. You are now armed more than ever with information to help you narrow down your choices to that final solar heater.

So, choose the solar heater that suits you best and raise your above-ground pool water temperature.
