Factors to Consider

As you can clearly tell by now, there are some great advantages to owning a quality electric pool heater, but how do you know which one to choose?

Although you could go with whichever model has the most electric pool heater reviews or simply close your eyes and wish for luck, in order to choose the best electric pool heater for you and your pool, there are a number of factors to consider, such as:


The greater the efficiency of an electric pool heater, the better it will perform and the lower its operating costs will be. While it’s easy to overlook operating costs in order to save a quick buck, the operating cost of a pool heater, even an electric model, can be significant over time.

Therefore, you should keep energy efficiency at the top of your must-have list when shopping for a new electric pool heater for your backyard oasis.

The energy efficiency of the electric pool heater is a little bit lower than gas pool heaters, but if you looking for the most energy-efficient way to heat your pool, the pool heat pump is a better choice for you. They are 5 times energy efficient and cost about 200$ per month.


The durability of an electric swimming pool heater is another important factor to consider. Although electric resistance pool heaters cost less than gas models, you still want your investment to last as long as possible, right?

Fortunately, most electric pool heaters, such as the ones above, are made with the highest quality parts and built to last for years, if not decades.

Pool Size:

The size of a pool plays a large role in how warm it can become with an electric pool heater. For instance, a 30,000-gallon swimming pool will heat more slowly and not become as warm as a 10,000-gallon pool, regardless of which type of heater you are using.

Since electric pool heaters are less powerful than gas pool heaters, they’re best suited for above-ground and in-ground pools up to 10,000 gallons in size.

Heating Element:

Most electric pool heaters utilize heating elements to heat up pool water as it flows over it. Therefore, the quality and power of the heating element should also be considered when choosing a great electric pool heater for your sparkling pool.

Control Panel:

The control panel of an electric pool heater is often overlooked, but it plays a key role in its ease of use. Nearly all quality electric pool heaters come with a display and control panel to allow you to monitor and adjust the temperature of the water in your pool. Some even come with digital control panels and have indicator lights to alert you to any malfunctions or potential problems.


Electric resistance swimming pool heaters cost a fraction of heat pumps and gas pool heaters. However, many still come with warranties capable of saving you some serious coin if they should happen to break down and need repair or replacement.

When looking at warranties, it’s important to consider more than their length and read the fine print to identify any conditions that may exist. As is the case with any other type of product, some electric pool heater warranties are more comprehensive and will serve you better than others.

Overall Ownership Costs:

Electric pool heaters typically don’t cost thousands of dollars like other types of pool heating systems, saving pool owners a nice chunk of change right off the bat. However, there are other costs associated with electric pool heaters other than their sticker price.

For example, the average 11-kilowatt electric pool heater draws 50-60 amps at 220-240 volts. Although this amount of electricity usage is considerably cheaper than the cost of running a gas heater, it will still be noticeable on your energy bill and should definitely be kept in mind.

Other ownership costs, such as installation, maintenance, and repairs, should also be considered.

A quality electric pool heater is one of the best investments a pool owner can make. However, with so much to consider and your hard-earned money on the line, it can also be a difficult one.

That being said, by considering your needs and each of the factors above, you’re sure to pick the right electric pool heater for your pool and enjoy warm and comfortable swims for seasons on end!


If you’ve buckled in and made it this far, then you can feel confident in the fact you’re now armed with much more information about electric pool heaters than the average pool owner. The only thing left to do is decide which unit is the best electric pool heater for you and click the buy button.

With winter on the horizon and temperatures falling each day, there’s no better time than now to invest in a top-quality electric pool heater. So, go ahead and do your due diligence, consider your needs, read the electric pool heater reviews above another time or two, and purchase a great electric pool heater that will keep your pool warm and inviting for years to come!
