How to Heat Your Florida Pool for Year-Round Swimming

Jacksonville, St. Johns, and Fruit Cove are known for gorgeous, sunny weather, but let’s be honest—between December and February, the water temperature in an unheated pool can drop into the uncomfortable 50s and 60s.

If you are investing in a beautiful backyard oasis, you should be able to use it 365 days a year. Adding a heating system to your pool allows you to swim comfortably through the Florida “winter,” host incredible holiday parties, and get a better return on your investment. Here are the best ways to keep your water warm.

1. Electric Heat Pumps (The Florida Favorite)

Electric heat pumps are the most popular, energy-efficient, and cost-effective way to heat a pool in Northeast Florida. Rather than generating heat from scratch, these units pull ambient warmth from the outside air, compress it, and transfer it directly into your pool water.

Because Florida rarely experiences freezing temperatures, there is almost always enough warmth in the air for a heat pump to work efficiently. They are incredibly reliable and cost significantly less to operate on a monthly basis than gas heaters.

2. Gas Heaters (For Rapid Heating and Spas)

Gas heaters (powered by natural gas or liquid propane) do not rely on the outside air temperature; they literally burn fuel to heat the water.

While they are more expensive to operate for daily pool heating, they heat water incredibly fast. Gas heaters are absolutely essential if you have an attached custom spa. When you decide you want to use your hot tub on a chilly January evening, a gas heater can bring the spa up to 102°F in a matter of minutes, whereas a heat pump might take hours.

3. Automation and Smart Pool Tech

The secret to efficient pool heating is automation. During our custom pool construction process, we can install smart systems that allow you to control your heater from your smartphone. You can schedule the heat pump to run during the warmest part of the day (when it operates most efficiently) and ensure the attached spa is perfectly heated before you even drive home from work.
