The movement of going green by opting for renewable sources of electricity has been gaining traction recently, thanks to the more public awareness of the devastating effects of fossil fuels. For those who want to be eco-friendly, we’ve included the SmartPool S220 Universal Sun Heater in our above ground pool heaters list.

Pool water will then go through the photovoltaic cells via a series of tubes and will be returned to the pool after having absorbed heat from the sun. The pool pump heater can raise pool temperature between 6 to 10 degrees Fahrenheit, which is not bad because it’s all thanks to the sun.
Installing the panel is very easy and can be a source of joy for those who have DIY projects. The photovoltaic cell is versatile and can be installed on the roof, rack, ground or fence. The above ground pool heater uses the existing pool pump to move the water into the tubes so there are no additional expenses needed.
Speaking of savings, you’ll love to learn that you’ll be enjoying a warm pool without costing you an arm and a leg in utility bills. The pool heater is admittedly much simple compared to gas heater, electric powered ones – you won’t find any fancy led panelboard for temperature control or a digital interface. But it does what its supposed to do which is bring up pool temperature a few degrees higher in the most cost-effective manner.
- Has an affordable price
- Uses renewable energy
- Cost-effective way to heat your pool

Blue Wave NS445 12-Mil Solar Blanket
The Blue Wave NS445 12-Mil Solar Blanket for Round Above-Ground Pools but if you have a round above ground pool at just the right size, then its perfect for you. The solar heating cover has insulating thermal cells which are designed to trap heat.
In this manner, your pool will retain its warmth even on cool cloudy days so you’ll still be able to enjoy warm pool water all summer, which is probably why many buyers who have tried this solar heater blanket say that it’s one of the best pool water heaters.
- UV-RESISTANT - Built for the outdoors, this Rectangular 12-mil Solar Blanket for In-Ground Swimming Pools can withstand exposure to UV radiation and will tolerate even...
- INNOVATIVE HEAT SOURCE - Our technology employs insulating thermal bubbles that trap heat from the sun. These innovative cells retain warmth for effective heat retention...
- EXTENDS THE SEASON - This thick 12-mil blanket uses passive solar heating to increase your swimming pool’s temperature up to 15 degrees Fahrenheit.
You can extend the swimming season by using this solar heater blanket without spending a dime on pool heater expense. It uses passive heating that can raise pool water temperature by as much as 15 °F.
The material used for this product is opaque and blue in color which allows maximum sunlight to reach the pool’s water below. This heat is then trapped inside the pool due to the insulating thermal properties of its thermal bubbles. Since the pool is completely covered, water evaporation is reduced to a minimum which, in turn, retains the heat collected by the water.
You might want to argue that this product does not actually generate heat by itself to increase the pool’s temperature. However, it also undeniable that this solar pool heater uses a clever method of trapping the sun’s heat and retain it longer in the pool so we’ve decided to include this one in this above ground heaters top list for 2020.
No need to worry about the sun destroying the blanket as it has been specifically designed to resist deterioration brought by years of direct exposure to sunlight. For your additional peace of mind, the solar pool cover also comes with a 3-year manufacturer warranty.
- A cost-effective way to heat your pool
- It's Affordable
- It's a solar heater so it only uses only the sun
- Performance in heating the pool depends on the sun’s light energy – won’t be effective during the winter season
Sun2Solar Clear 18-Foot Round Solar Cover
The Sun2Solar Clear 18-Foot Round Solar Cover 16 Mil is another excellent product that relies on sun energy to keep your pool warm and comfy.
If you happen to search it up in any online retailer site, you’ll soon understand why we’ve also included this in our guide; people just love its performance and gave it high ratings to show their satisfaction for the product.
Evaporation of the pool water is one of the major reasons for heat loss as it allows heat to be released back into the surroundings.
- SAVE ON HEATING COSTS - Sun2Solar clear solar blankets are made from a film of thousands of tiny bubbles, which work together to collect and retain heat in your pool at...
- MINIMIZE WATER EVAPORATION - The use of a solar cover helps in preventing up to 95% of pool water evaporation. When not enjoying a refreshing swim, keeping your pool...
- HEAT RETENTION - After everyone has called it a day with wrinkled fingers from too much fun in the sun, make sure to place this solar cover back atop the water. Don’t...
But with the Sun2Solar cover, it won’t be happening as rampantly and the blanket actually prevents evaporate by up to 95 percent. Since evaporation is minimized, most of the pool water’s heat remains trapped and, by the time you decide to take a dip, it will still be comfortably warm for your enjoyment.
This is made possible due to those thousands of tiny bubbles on the cover. Since the cover is transparent, it allows UV rays from the sun to penetrate into the water eventually heating it up. However, the bubbles also act as a heat insulator effectively sealing the heat within the pool. Obviously, the cover works as it is featured in most above ground pool heater reviews.
The best part is that you are not spending on electricity to keep the pool water warm. The sun is doing all the hard work for you. Even if you also use conventional water heating like using gas heater or electric heater, you’ll still be saving a lot on heating expenses since the cover will still act as an insulator trapping the water’s heat regardless of what kind of heating you used to increase its temperature.
- Cover’s tiny bubbles effective in trapping heat
- Reduces heat loss via evaporation even during the day
- Can be easily trimmed to fit your pool
- Solar powered
- Some customers have complained that it’s not as durable as they expected
Blue Wave NS6022 SolarPRO XD3 Dome Above Ground Pool Heater
Design-wise, the SolarPRO XD3 Dome Heater with Bypass Kit is a bit different from the usual. It’s compact and looks good with its minimal footprint so we’ve decided to include this model in the amazing pool heaters list specifically for those homeowners who want it unobtrusive.
Like all solar heaters, the Dome Above Ground Pool Heater offer homeowners the option to enjoy a comfortably warm pool heated in an environmentally friendly manner. But this pool heater does it a bit differently – it’s a departure from the usually bulky solar panels of other heaters.
- 60 ft. of hose for maximum solar heat transfer
- Connects to 1.25", 1.5" and Intex hoses
- Space saving footprint
The pool heater is actually minuscule compared to the bulky panels of other heaters. It has a circular based around 23 cm in diameter which houses a coiled piping system within a transparent dome-shaped enclosure.
The dome structure of the enclosure is actually critical to the design of this pool heater as it produces a greenhouse effect which enables the heater to increase the pool water’s temperature despite its limited surface area.
The unit can get the pool heat up by up to 5 degrees in three to eight days depending on pool size. Obviously, there are some buyers who feel that it takes too much time for it to sufficiently heat the pool. One possible solution to increase heating efficiency is for two or more units to be connected in a series.

- Minimal space requirement
- Solar powered
- Complaints about hose connection being too small and leaky
- Takes more than a day to heat up the pool
Fafco Solar Bear Economy Heat System
The company behind the Fafco Economy Heating System has been in the solar panel manufacturing business since 1972 and every customer loved their products.

- Made in the USA for quality you can count on
- Compatible with your existing pool pump
The system is designed to heat an 18 to 24-foot round pool by as much as 10 °F. A large pool might need more than one panel to achieve the same performance but it’s best to contact your favorite retailer to get your pool officially measured.
One thing that distinguishes this Economy pool heater is that it has unique parts like the bypass valve which allows you to turn off the heater system once the level of heat is already to your liking. This is unlike other solar heaters where it will continue to heat the pool’s water as long as the pump is running and the only way to stop the temperature increase is to turn off the pump.
The system works best between 10 AM and 4 PM. The solar unit must be directly hit by sunlight which explains why the manufacturer recommends that the panel must be on the roof, on a rack or on the ground, provided that there are no trees or buildings nearby that may obstruct direct sunlight.

- Virtually maintenance-free
- Installation can be a challenge

Factors to Consider When Shopping for Pool Heaters
So you are now all fired up to go shopping for the perfect above ground pool heater for your pool to make it usable during cold months.
Before you make a buying decision, please be reminded that you need to carefully weigh all your options and consider a few important factors before taking the plunge and buying any available pool on the market.
Heaters for your pool can be classified by what kind of fuel they consume to heat the water. There are solar heaters which solely rely on the sun’s heat and, is therefore very cheap to operate. The downside is that they might not function efficiently in colder months.
There are heaters available that works with natural gas or propane which can operate all-year-round but will carry a certain amount of risk (gas leaks, for instance) and added fuel costs.
And lastly, there are electric-powered heaters as well as a heat pump which are very convenient because you don’t have to worry about buying fuel and also suitable for winter use. But, as everyone knows, these heaters will jack up your monthly electricity bill.
The size of your swimming pool will affect, to a certain degree, the heater models that will suit your needs. All pool heater models have their limitations when it comes to heating performance. As you might have noticed, some are marketed only from smaller pools because they are not powerful enough to heat larger ones or increase the water temperature efficiently.
Be sure you choose a heater or a pool heat pump that is just right for your swimming pool’s size and take a look at the manufacturer’s size chart for other models that might suit your needs better. Owners of a larger pool might also want more energy efficient ways to heat up the pool water such as by using a heat exchanger.
Some pool heaters are simple enough that you can install them on your own as a DIY project. Others, however, are a bit complicated that they would require a professional to get the job done properly. Be sure to know these things beforehand and, more importantly, inquire if there are any additional installation fees involved.
In case of heating above ground pools that use salt water, be sure to choose a product that can withstand the corrosive properties of seawater.
Ultimately, choosing the right product for you will be a personal decision. It is necessary to make a comparison of the advantages and disadvantages of each pool equipment and pump available.
For instance, a solar-powered pool heater will help you trim down your electric bill but it also makes your pool unusable when the climate gets really cold. On the other hand, propane-powered equipment or heat pumps are good for all-season pool usage, but you must also be prepared for the increased maintenance and fuel cost.
It is our wish that, even though you might not select the exact products offered in this article, this guide might somehow help you in your journey to finding the perfect above ground pool heater you’ve been looking for.
