Is the Pool Heated? Here’s How to Know Before You Buy (or Dive In)
In Florida real estate, pools are often a big selling point—but a heated pool? That’s an upgrade many buyers are willing to pay for. Whether you're buying a home or listing one, it's important to know what to look for when evaluating a pool’s heating capabilities. Some signs are obvious, while others take a bit of detective work.
This guide breaks down how to tell if a pool is heated, what types of systems exist, what they cost, and what clues to look for during a showing or inspection.
Start with the Basics: Test the Water
On a cool morning or shaded day, the fastest way to get a clue is to touch the water. A comfortable temperature likely means the pool is heated—especially if the outside air is cooler. Unheated pools will feel cold to the touch unless they’ve been baking in the sun all day.
However, keep in mind that some heaters are only used seasonally, so the absence of heat doesn’t necessarily mean the system isn’t installed—it may just be turned off.
Look for Pool Heating Equipment
If you want real answers, the equipment pad is where you’ll find them. Every type of pool heater has distinct features, and most are located near the pool’s filtration and pump systems.
1. Gas Pool Heaters
-
How it works: Burns natural gas or propane to heat water as it circulates through the system.
-
Appearance: Compact, metal box with a vent on top and usually a control panel on the side.
-
Common brands: Pentair, Hayward, Raypak.
-
Cost: Around $2,000–$3,500 for the unit; installation can add another $500–$1,000.
-
Pros: Heats water quickly, ideal for occasional use.
-
Cons: Higher ongoing fuel costs; less efficient for long-term daily use.
2. Electric Heat Pumps
-
How it works: Uses ambient air to warm the water (similar to an HVAC system).
-
Appearance: Large box with a visible fan on top, like an outdoor A/C unit.
-
Common brands: AquaCal, Pentair, Hayward.
-
Cost: $2,500–$5,000 for the unit, plus $1,000–$2,000 for installation.
-
Pros: Very energy-efficient, especially in Florida’s warm climate.
-
Cons: Slower to heat water than gas, but more cost-effective over time.
3. Solar Pool Heating Systems
If you’re viewing a home in the middle of the day and the water feels warmer than expected, look up. Solar panels for pool heating are often installed on the roof, especially south-facing sections. These systems are low-maintenance and cost-effective in Florida’s sunny climate but may not work well year-round without a backup system.
-
How it works: Pumps water through black solar panels mounted on a roof or rack, using the sun’s heat.
-
Appearance: Rows of flat, black panels, often on the south-facing side of the roof.
-
Common brands: FAFCO, Heliocol, Aquatherm.
-
Cost: $3,000–$7,000 for full installation (can vary widely based on size and layout).
-
Pros: Eco-friendly and low-cost to operate once installed.
-
Cons: Weather dependent; less effective on cloudy or cold days.
Check for Control Panels or Thermostats
Most heated pools will have a thermostat or automated control panel located near the pump system, in the pool equipment area, or even inside the home. These allow you to adjust the water temperature or set heating schedules. Newer systems may integrate with mobile apps or smart home hubs.
If you’re touring a home and you see a digital screen labeled with temperature settings, you’ve probably found the heater controls.
Ask the Right Questions
-
Is the pool currently heated?
-
What type of heating system is in place?
-
When was the system last serviced?
-
Is the heater operational?
-
Is it under warranty?
These answers can help you determine not just whether the pool is heated, but whether it’s a reliable, functional system—or an expensive repair waiting to happen.
Review Utility Bills or Maintenance Records
If you're buying, it’s smart to ask for recent gas or electric bills from colder months when the heater may have been used. This can give you an idea of ongoing operating costs.
Also, request service records if available. A newer system that’s been professionally maintained is a big plus.
Conclusion: Heated Pools Are a Smart Upgrade—If You Know What to Look For
A heated pool adds value, comfort, and year-round enjoyment. But just because there’s a pool doesn’t mean it’s ready for winter swims or late-night dips. With this checklist, you can confidently assess whether a pool is heated, what system it uses, and whether it’s worth the investment.
