The movement of going green by opting for renewable sources of power 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.
This pool heater is pretty straightforward in its approach – it uses the sun’s heat to heat the pool water. The system is composed of black polyethylene panel that measures 2 by 20 feet, which is designed to effectively capture the sun’s heat.

Pool water will then go through the panel via a series of tubes and will be returned to the pool after having absorbed heat from the sun. The pool heat pump 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 panel is versatile and can be installed on the roof, rack, ground or fence. The 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 heated pool without costing you an arm and a leg in power bills. The pool heater is admittedly much simple compared to gas, electric power ones – you won’t find any fancy led control panel 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.
The Blue Wave NS105 8-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 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 blanket say that it’s one of the best pool heaters.
- RETAINS HEAT – Insulating thermal cells trap heat and retain warmth on cool cloudy days allowing you to swim in warmer water all summer long.
- LONG-LASTING – Created with UV-protected polymer, our solar blankets are resistant to the deterioration caused by chemicals and UV radiation.
- EXTENDS THE SEASON – This high-quality 8-mil solar blanket uses passive heating to raise your swimming pool’s temperature by up to 15 degrees Fahrenheit.
You can extend the pool season a bit longer by using this solar blanket without spending a dime on pool heater expense. It uses passive heating that can raise pool water temperature by as much as 15 degrees Fahrenheit.
The material used for the cover 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 argue that this product does not actually generate heat by itself to increase the pool’s temperature. However, it also undeniable that it 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 pool heaters top list for 2019.
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 you additional peace of mind, the pool cover also comes with a 3-year manufacturer warranty.
The Sun2Solar Clear 18-Foot Round Solar Cover 16 Mil is another cover that relies on the power of the sun to keep your pool warm and comfy.
If you happen to look it up in any online retailer site, you’ll soon understand why we’ve also included this in our pool heaters 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 heated up. The sun is doing all the hard work for you. Even if you also use conventional pool heating that uses gas or electric, 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 type of heating you used to increase its temperature.
Design-wise, the SolarPRO XD3 Dome Heater with Bypass Kit is a bit different from the usual.

Like all solar heaters, the Dome 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.
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 small surface area.
The unit can heat the pool 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 long 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.

Factors to Consider When Shopping for Pool Heaters
So you are now all fired up to go shopping for the perfect heater for your pool to make it usable during cold weather.
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.
Heaters can be classified by what type of fuel they consume to heat the water. There are solar-powered pool 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 pool heaters that are natural gas or propane powered 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 power 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, there are heaters that are marketed only form smaller pools because they are not powerful enough to heat up larger pools.
Be sure you choose a heater that is just right for your pool’s size and check out the manufacturer’s size chart for other models that might suit your needs better. Owners of larger pools 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 pool heaters 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 type of equipment and pool heat pump.
For instance, a solar-powered pool heater will help you trim down your electric bill but it also makes your pool unusable when the weather gets really cold. On the other hand, a propane powered equipment is good for all-weather 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 list, this guide might somehow help you in your journey to finding the top above ground pool heater you’ve been looking for.
