Frequently Asked Questions
Is A Pool Heater Worth It?
Yes, especially in the Florida Keys, where coastal breezes and cooler months can make your pool too chilly to enjoy. A pool heater extends your swim season, increases comfort, and adds value to your home.
How Long Does It Take To Heat A Pool?
It depends on the type of heater, the size of your pool, and the starting water temperature. On average, it can take anywhere from 12 to 48 hours to reach your desired temperature, especially if you’re using a heat pump or solar system.
How Many Hours Should I Run My Pool Heater?
Most homeowners run their pool heater just long enough to maintain a comfortable temperature. In moderate conditions, this may be 4–8 hours per day. Heat pump systems are most efficient when used consistently rather than in short bursts.
