What if we told you that there is an affordable and efficient way of making every season a pool season? Sounds too good to be true. But we are here to convince you otherwise.
The trick to achieving this dream is quite simple, really, as all you need is a pool heater that fits your needs as well as your budget.
But coming across such a heater can be a daunting task for any buyer. And if you’re struggling with the same dilemma, you have stumbled on to the right guide.
After thorough and extensive tests on all the pool heaters that the market has to offer, we’ve handpicked for you, some of our personal favorites that are sure to fit all your swimming needs.
But before we get any further in best pool heater reviews, let’s take a look at the different kinds of heaters and their specific advantages and disadvantages.
Types of Pool Heaters.
You might be asking yourself, ‘what size do I need?’, but the functions of a pool heater has more to do with type than size. And there are as many types as there are customer demands, so it’s essential to pick the one that best suits your pool and your needs.
To make your choice more accessible, we’ve listed out the more popular and affordable ones.
1. Gas Pool Heater.
With a gas engine base, the gas pool heaters run on the principle of combustion. As the water passes through the filters, the combustion chamber warms the water as it’s returning to the pool. Therefore the tube in which the water travels is continuously heated to keep the pool warm for a more extended period.
Initial Costing and Long-Term Outlook.
Even though the initial purchase is cheap, the long-term fuel cost and maintenance makes the gas pool heater quite an expensive investment. The initial purchase of any acceptable gas heater may be as low as $1500, but as gas is not a renewable resource, obtaining fuel regularly, can become costly.
- Heating is almost instantaneous.
- Affordable above ground pool heater.
- Cheap initial buy.
- High fuel cost.
- A non-eco-friendly option.
The gas heaters are all about speed and are perhaps one of the best ways to heat above ground pools. The best part is it heats the water almost instantaneously.
And as gas heaters mainly run on natural gas or propane, its heating ability is not inhibited by factors such as weather and temperature.
2. Electric Resistance Pool Heater.
The electric heater warms the pool water in short, methodical cycles. As its thermal unit generates heat by electrical currents with the help of an external power source, the water is then allowed to pass through the resistor which heats it.
But a more symbiotic process happens here, while the resistor heats the water, the water, in turn, cools the resistor down so that the cycle can start anew.
Initial Costing and Long-Term Outlook.
Though a more eco-friendly alternative to gas heaters, the electric heater in comparison is not as energy efficient and will incur higher electric bills. But just like the gas device, its initial buy is cheap as well and ranges around $2000.
- It gives a year-round operation as it needs low maintenance.
- Easy installation.
- Simple cyclic heating process.
- Not energy efficient.
- The cost of operation can get expensive.
An electric pool heater might appeal to you more if you’re looking for a more eco-friendly option than a gas pool heater. Even though it might take a longer time to heat your pool, its installation is easy, and it’s heating procedure is more thorough as well.
3. Pool Heat Pump.
The pool heat pump uses air as its primary heat source; it imbibes the heat from the surrounding atmosphere and then feeds it to the heat exchanger. The cold water passes through the heat exchanger and gets heated as a result. The water is then channeled back into the pool.
Initial Costing and Long-Term Outlook.
The more conventional heat pumps come at a range between $2000-$4000 and mostly yields a COP of 5.0-6.0. Even though cheap and efficient, a heat pump can only function optimally until a particular air temperature threshold, which lies at around 50 degrees for most models.
- High energy efficiency calls for a low operation cost.
- They are not affected by weather change.
- It has a longer lifespan than other heaters.
- Temperature restricted.
- Our Thoughts.
When it comes to pool heating systems, none are as efficient as air-source pool heat pumps. For a pool water heater, the pool heat pump is unique as it uses air as its primary heat source.
The heat pump’s operational cost is low as well as it mainly runs on sustainable resources making it a natural gas pool heater that utilizes minimal amounts of electricity.
4. Solar Pool Heater.
The solar pool heater functions by harvesting renewable solar energy. Its panels are installed strategically around the pools, thereby acting as the primary heat source. The water is then drawn into the pump system and let out through these panels, thus getting heated while it returns to the pool.
Initial Costing and Long-Term Outlook.
The solar heaters are expensive when it comes to the initial purchase and lies within a range of $4000-$7000. But it more than makes up for it in the long run, as it utilizes renewable energy, which keeps its operational cost low and doesn’t need periodic maintenance.
- Most eco-friendly pool heater.
- Low cost of operation.
- Zero harmful emissions.
- Expensive initial purchase and setup.
- Highly weather dependent.
Solar pool heaters are one of the most eco-friendly options for keeping your pool warm in the coldest of winters. Even though its mode of operation is weather restricted and non-functional on cloudy days, it makes up for it by being amazingly cost-effective.
As the solar heater is naturally powered, its heating action is slow as well, but to balance it out, you can always pair it with a low-grade pool heat pump.

Pump heaters are not known to be fast at water heating, especially when compared to gas-powered devices. But the Hayward HP21404T HeatPro 140.000 will heat your pool almost as quickly as any other gas heater, if not faster.
And it’s all thanks to its cutting-edge titanium build, which makes the tool’s performance unrivaled and uncompromising even under the harshest conditions.
The HeatPro is exceptionally robust and long-lasting, as well. It features heavy-duty, “super-quiet” scroll compressors with an injection-molded UV-resistant body, which keeps it resistant to rust and physical damage. You’ll not have to worry about its maintenance regularly.
Its lightweight and compact body are quite easy to install and maintain. Its highly flexible features make it perfect for both new pools and existing systems alike.
A bigger model of the HeatPro series of heat pumps, the 50,000 BTU caters to the bigger pools that reside primarily in the coastal areas. It comes with an Ultra Gold corrosion-resistant evaporator fin, which is ideal for facing the moisture and salt in the air and the stormy weather of the coastal regions.
Along with the fins, the 50,000 BTU even has a polyethylene screen that protects the evaporator coil hence reducing maintenance costs by keeping the heater functional for long.
And if you live in a crowded neighborhood with noise-sensitive neighbors, then you’ll be happy to know that this device has an acoustic compressor cover. Not only does it minimize the compressor sound level, but along with the profiled fan blades, it ensures quiet and efficient airflow as well.
