Best Above Ground Pool Heater Reviews 2019

With summer quickly approaching, individuals and families everywhere are considering becoming first time above ground pool owners. One of the key components to above ground pools is, surprisingly, an above ground pool heater or even pool ladders.

While pool owners in warm climates may think of above ground pool heaters as unnecessary, pool heaters can extend the swimming season and provide comfortable relaxation throughout the year in any number of locations and climates.

In cooler climates with only a couple of months of swimming weather, pool heaters are an absolute must for extending the swimming season.

If the thought of swimming season coming to a close and shutting down the pool for the winter makes you a little sad or anxious, a pool heater could be a great edition to your leisure time.

With the proper equipment, you can extend the swimming season weeks or even months into the late fall, or get into the pool quicker by warming the water up in early spring.

Above Ground Pool Heater Types

There are many different methods to heating your pool, both natural and electric.

Gas Heaters

Perhaps the best, but most expensive, way to warm your pool, gas heaters raise water temperatures quickly. Natural gas heaters are reliable, safe, and efficient.

Most natural gas heaters connect directly to your home’s existing gas line and are simple to install and use. Propane pool heaters, conversely, do not have to be hooked up to the existing propane line and are self-sufficient and easy to install.

Digital propane pool heaters run automatically after you set your desired water temperature, just like a thermostat in your home heating and air system.

There are less expensive manual options that will work just as efficiently with a bit more interaction from the owner. Both natural gas and propane gas pool heaters run about the same for the unit itself.

Solar Covers

Solar covers are easy and cost effective – they heat up during the day and retain warmth throughout the night. Solar covers come in a wide variety of thicknesses, colors, and sizes.

You may also find a solar blanket – lying on the water instead of sealing the entire top of the pool – is plenty efficient for your needs.

All quality solar covers should be UV protected and will last for years properly stored. Solar covers work by trapping water evaporation and solar radiation – think of a greenhouse effect.

This process may raise water temperatures by up to 15 degrees with regular use.

One additional accessory to consider if purchasing a solar cover: a solar cover reel! These handy instruments make unrolling your solar cover over the pool much easier and provide handy storage for solar covers when not in use.

One person can easily put the solar cover on or take it off using a solar cover pool reel. Typically, above ground solar cover reels comes with a good price tag.

Solar Heaters

For those eco-conscious and fiscally conservative pool owners, solar heaters use solar energy to warm the pool waters instead of gas.

Solar technology is not popular in many parts of the world, so it can seem like an illogical option to many users.

However, this is a great way to cut down on your effect on the Earth, not to mention save big money on utility bills month to month.

So, how do solar heaters work? Let’s review the technology for any above ground pool owner considering the option of a solar heater but unfamiliar with solar powered technology.

Pool water is pumped through your above ground pool’s filter system and passed through a solar hot water collector – a thin, flat box usually mounted on a roof or wooden mounting rack.

The collectors absorb the sun’s solar rays to heat the water running through the unit. Unlike solar panels, which convert the sun’s rays into electricity, solar pool heaters use the sun’s rays directly, heating up the water in only one step.

One very cool thing about solar heaters is that they can be used to cool down water in hot climates by running the system at night!

There are several different types of solar heaters, so determine the best option for your pool setup by knowing the differences between the different solar heaters.

“Unglazed” collector systems are generally less expensive, because they don’t have glass coverings, instead using rubber or plastic parts.

These units are absolutely fine for use in warmer climates. If you plan, however, to use a solar heater in temperatures below freezing, you’ll want to consider the more expensive glass glazed setups.

Solar heating systems can be one of the most price effective methods of heating your above ground pool, because most of the components of the system are already installed in your pool – a pool pump and filter system, primarily.

The solar heater is simply installed in the line of this existing setup. Size is another factor to consider, as you will need increased size collectors for your solar heater depending on the size of your above ground pool.

Solar covers can be used in addition to a solar heater to retain heat at night, making the solar heater more effective by preventing loss of heat through the surface of the pool.

The best place for your solar collector would be on the roof of your home, facing south for maximum collection of sun rays, however, it is not an absolute requirement to mount the panels to the roof if you receive maximum sunlight in another area of the yard closer to the pool.

You can also build a wooden mounting rack to get the panel up off of the ground. Let’s review some options for solar heaters.

For solar heaters to work with maximum efficiency, they should be receiving direct sunlight between 10:00am and 16:00pm.


Blue Wave NS6028 Solar Heater for Above Ground Pools


bluewave solar above ground heater


This solar heater is designed for above ground pools up to 30 feet in diameter or with a capacity of 12,000 gallons. At a very good price, its unique curve shape allows for maximum heat absorption with such a large surface area to soak up the sun’s energy.

This unit does not require mounting additional solar panels to the roof or a wooden mounting rack.

As opposed to other types of above ground pool heaters, this unique heater will lower the amount of time it takes to heat the water in your pool while also increasing the heating capacity up to 40% per cycle, all while saving money on your electric bill.

This solar heater states it will raise the water temperature in your above ground pool by 5 degrees in 5 days, so it isn’t as immediate as other methods.

Once connected, your above ground pool pump filtering system feeds water into the heating station through the solar coils and is warmed by the solar energy collected and stored within.

Water drains through the exit port and post into the existing return and empties into the pool, gradually increasing water temperatures.


  • Energy efficient, works with existing pump system
  • Large surface area and many solar coils for maximum solar capacity


  • Does not raise temperatures as much as other methods
  • Takes at least one full cycle to raise water temperature

  • Inexpensive option with ability to add more units for larger pools
  • Easy installation, no hookups to existing power sources necessary
