Tips on Choosing the Best Above-Ground Pool Heater

Research heating options

As we can conclude from the list, there are various options for heating your pool. Some of coming with more lifetime costs and some come with zero added expense. This first tip is all about researching the various models to learn about the ins and outs of their functioning.

By researching specific heater options and comparing them side by side, you’ll be able to better grasp the details in each one that sets them apart.

There also may be terms and vocabulary related to pool heating that you’re not upon. It’s best to look up whatever you’re unsure about to prevent any misunderstandings and potential future regrets.

Ask other pool owners for opinions/information

Swimming is one of the most common spring and summer activities there are. Because of this, you likely have acquaintances who have pools of their own or who know others they could put you in contact with.

That being said, they can give you some of the best, primary information regarding their experiences with pool heaters and how they function. While you don’t want to be playing a game of 20 questions, don’t hesitate to seek out information from this treasure trove of knowledge.

Pay attention to brands

A final tip would be to pay attention to the brands behind the heaters. It can be limited to only searching out certain brands and their products, and that’s certainly not the suggestion here. Instead, what we mean is that you should note the brand behind the product and gather information on them.

This means doing a simple internet search to determine credibility and the company’s responsiveness, etc. Buying a cheap or malfunctioning product can be a pain, but that pain can grow if the brand behind the product goes missing in action regarding customer service.

Factors To Consider When Buying The Best Above-Ground Pool Heater

Your pool and space

The first factor to consider before buying an above-ground pool heater is your pool and space. The shape and size of your pool are important in the shopping process. Certain heaters, such as solar blankets, are generally fitted for specifically sized and shaped pools.

Other models, such as the solar collector mat models, may require you to buy more than one set to properly heat your pool if it’s large. In the same vein, you want to be sure your space is suited for the heater of your choice.

Solar-based heaters require direct sunlight for the majority of the day. Does your yard get plenty of direct sunlight? Is your roof (for panels) reasonably close to the pool? For gas-fueled heaters, do you have a specific area viable for installation? All of these factors of your space are going to play a part in your decision.

The desired magnitude of heating

The next factor to consider is the magnitude of heat that you’re looking for. The solar-based models are generally weaker at heating the entire pool because of the reliance on proper sunlight, though it heavily depends on the make and model.

The high-grade units, such as the Hayward and Pentair models, will provide strong heating at pretty exact temperatures chosen by you. Some folks are looking to extend the swimming season while others are simply looking to take off the cold edge of the water. Knowing which type of heat you’re in need of will help you to narrow your options.

Customer reviews

A final factor to consider before buying your above-ground pool heater is other customers’ reviews. While you don’t want to put too much stock in them, it’s good practice to peruse the reviews and comments on products to see if there are any recurring issues or consensus opinions about products and their functioning.

If there’s a major issue with the product you’re looking into, it’s most likely to make itself known to you via customer reviews and comments. After all, no company would describe its product missteps and miscalculations.

The Best Above Ground Pool Heater FAQ

Should I go the solar route?

This question boils down to whether or not you’re looking for super-powerful pool heating and your stance on extra utility expenses. Solar heaters operate best when they’ve been basking in sunlight for extended periods of time, which evades them as the weather turns colder again. However, solar panels will provide comfortable warmth through those chilly summer nights, and at no extra expense. So if you’re looking for something to take the edge off practically free, solar heating is your best bet.

Are the natural gas heaters easy to install?

Unfortunately, gas-fueled above-ground pool heaters are not easy installs. They typically require the hand of a professional. There are surely some people out there who may be capable, but for the hands-off among us, definitely call in a professional helping hand. Also, in addition to their difficult installation, you’re continually hit with the expense of refueling the units.

How are solar blankets effective?

In concept, think about the way that blankets and covers keep us warm when they encompass us. They trap heat and deflect it back at our bodies, keeping us warm. It’s the same with solar blankets for pools except that the heat comes from the sun and is transmitted through the blanket. This keeps the water warm. By allowing sunlight in before trapping it, the blankets are capable of keeping your pool warm through the night until you’re ready to again the next day!


As with most pool accessories and parts, the best above-ground pool heater for you largely depends on what kind of pool you have and how you wish to heat it. There are heating options available for all types of interests.

First, there are solar options that are environmentally friendly and reduce heating expenses to zero. Next, there are the electronic heaters that are very effective but require extra energy, and thus, more utility costs. And for the high-powered, high-grade tech fanatics, there are the natural gas-fueled heater units.

No matter the type of pool you have, these above-ground swimming pool heater reviews should go a long way in aiding you with your shopping experience.

By dissecting the details and specs of various models, we’ve laid the groundwork for you to start making direct comparisons and figuring out which option is best for you. The swim season’s upon us and right about now would be the perfect time to start heating that pool. Get your above-ground pool heater today!
