Gas Pool Heaters: Benefits, Costs, and Top Products

Gas Pool Heaters: Benefits, Costs, and Top Products

Even though Florida isn’t known for frigid temperatures, winter weather can still make your outdoor swimming pool too chilly for a relaxing dip. When the seasons change, and cold air begins moving in, you’ll want a reliable way to control your water temperature. This is where gas pool heaters come into play. Join us to learn why so many homeowners choose gas for their heated swimming pools!

What are gas pool heaters?

Gas pool heaters are a great alternative to solar and electric heating systems, which face various limitations. Here’s a guide to these popular, powerful pool accessories: 

How do gas pool heaters work?

Gas pool heaters connect to your home’s natural gas line or a propane tank to supply power. Since they’re installed at the end of your pool’s circulatory system, water passes through the pump and filter before entering the heater. The gas burns in the combustion chamber, and heat transfers through the heat exchanger, where it’s absorbed by the water before flowing back into the pool.

Are gas pool heaters better than electric pool heaters?

That depends on how you plan to use it. While there’s no one-size-fits-all heater for every pool and spa, gas systems are ideal for rapid heating. This means faster heating times if you hardly use your pool, regardless of cloud cover, humidity, and ambient temperature. On the other hand, solar-powered or electric heaters can be more cost-effective for folks who swim year-round. 

What’s the average cost of a gas pool heater?

Of course, there’s a trade-off for all that power. Even though the purchase price of a gas pool heater is lower than that of a heat pump, it typically costs more to operate and may require more frequent replacement. You can expect to spend anywhere from $200 to $1,000 per month to keep your pool hot in winter, depending on:

  • Pool size

  • Heat source (natural gas vs propane)

  • Water temperature

  • How frequently you swim in colder months

Benefits of gas pool heaters

Let’s explore the benefits that make gas pool heaters worth the higher sticker price. 

Faster heat-up

Speed is the factor that attracts most homeowners to gas pool heaters. In fact, a 400,000-BTU system can raise your water temperature by up to 2.5 degrees Fahrenheit per hour. Depending on the size of your pool, it may only take eight hours to raise the temperature by 20 degrees F. In contrast, a heat pump is limited to 0.5 degrees F to 1.5 degrees F per hour and can take 24 to 72 hours to heat the same amount of water. 

Year-round use

Unlike solar pool heaters, which rely on direct sunlight, and heat pumps, which require warm ambient air, gas pool heaters operate independently of the climate. No matter the weather, these systems reliably increase water temperature. In turn, you can extend your swimming season to all 12 months of the year. 

Lower initial costs

We know that gas pool heaters incur higher operating costs, but what about the purchase price? It turns out that gas and propane systems cost less than many other alternatives, like solar. You may find relatively inexpensive heat pumps on the market, but they won’t match the performance of a gas or propane model.
