4 Best Solar Heaters For Above Ground Pool To Extend The Swimming Season

When it starts to get cold, it can be difficult to still go swimming in your above ground pool.

This product can increase the overall temperature of your pool and ensure that you’ll feel comfortable – even on a chilly day.

Solar Heaters For Above Ground Pool

Solar heaters work in a similar fashion to water heating systems. The only difference between them is the energy source that will propel the pool water through the system. Above ground heaters use solar energy collectors that are usually mounted on the roof or placed on the side of the above-ground pool.

How it works is simple. Water gets pumped through the built-in filter, which helps to remove any contaminants in the water. It then goes through the tubes within the solar energy collectors, and the heat from these tubes helps to warm up the water before they’re released into the pool.

If you’re thinking of purchasing a solar heater for above ground pool, you could be overwhelmed by the number of options on the market. To help, we’ve created a guide of what you should look for when purchasing your above ground heater and curated a list of 4 of some of the best above ground heaters to get you started.

Benefits of Above Ground Heaters 

One of the biggest benefits of above ground heaters is that they can warm up pool water and make it more comfortable to swim in. Using a solar powered above ground heater is also an efficient way to warm up the water in your above ground pool. It’s also practical since you won’t be relying on electricity.

They’re also an excellent option for individuals who want a more energy-efficient system to help with heating their swimming pool water. Since it’s eco-friendly, above ground heaters are also a fantastic choice for those that want to reduce overall carbon emissions.

Other benefits of purchasing above ground heaters include minimal maintenance costs and are easy to install. Since there’s no electricity source required, you don’t have to worry about tangled wires or hiring an electrician. Instead, you’ll just have to follow the instructions that your above ground heater comes with, and you’re all good to go.

Pros and Cons for Above Ground Heaters 


  • Cost-friendly. Since you won’t have to pay for electricity or natural gas expenditure, you’ll be minimizing cost on your overall electricity bill.
  • Eco-friendly. Since an above ground heater relies on solar power, you’re doing your part for the environment and reducing the impact of electrical or natural gas sources.
  • Doesn’t require much maintenance. You might take a little bit of time to install your above ground heater, but you won’t have to worry about maintenance. While above ground heaters that run on traditional electrical sources might need periodic maintenance, you won’t run into that issue with solar above ground heaters.
  • Easy installation. Upon your purchase, you’ll receive detailed instructions on how to go about installing your above ground heater. You won’t have to hire a specialist and can even view it as a DIY project for an afternoon.
  • You’ll have the perfect water temperature at all times. Most above ground heaters come with controllers where you can adjust the water to your desired temperature.


  • Mounting is required. With solar above ground heaters, you’d need to mount the solar collectors, and they’re quite bulky as they need to be at least half the size of your swimming pool.

What to Look for in Above Ground Heaters 

Now that you’ve got a better idea of the benefits of above ground heaters, the next thing to consider is what you should look for when purchasing one. There are three different types of solar panels that can help with collecting energy – solid solar panels, individual solar panels, and glazed and unglazed solar panels.

Solid solar panels are similar to the panels you have in traditional solar power systems. They’re usually able to harvest the most energy when the angle of the board is perpendicular to the sun’s rays – generally around noon. Hence, solid solar panels typically provide optimum performance at noon, with their performance diminishing throughout the day. Solid solar panels also run the risk of being blown away by the wind, so you’ll need to install additional security straps.

With individual solar tube panels, these have several tubes that are arranged side by side. They’re much sturdier than individual solar panels in that regard and run less of a risk of being blown away. It’s also a more efficient energy collector than some of the other panels as each of the individual tubes can absorb heat.

With the panel above, they can also be glazed and unglazed. Glazed solar panels are usually ideal for those living in colder temperatures, while unglazed solar panels are better for those living in warmer climates.

Some other things you’d need to consider when making your purchase include the clarity of installation instructions. Most above ground heaters are easy to install, so you won’t need professional help – but that’s only if the manual is written clearly. Some manufacturers can use terms that are too vague or hard to understand. To be sure, you’d want to look at the customer reviews before making your purchase.

The next thing to consider is the size of the solar collectors. If you’ve got a bigger pool, for example, you’d need a bigger solar collector. You’d also want an above ground heater that can increase the temperature of your water by about 5 to 10 degrees Fahrenheit. After all, there’s nothing like being able to swim in warm, comfortable waters while it’s cold outside.

Next, you’ll want to consider the quality of the construction. A solar above ground heater comes with various components from the controller to the collector, pump, and filter. There are also tubes and hoses, and you’ll want to make sure that they all come with solid construction. Ideally, they should be UV, corrosion, and rust-resistant, and made of industrial-grade materials.

Finally, your above ground heater should be easy to use. The controller should be easy enough to operate, and you should be able to get your pool to a comfortable temperature in no time at all. If you’re thinking of getting a portable above ground heater, they should also not be too heavy so you can carry it from your home to the pool.
