How much does a pool heater cost?
Pool heater cost in 2026 runs roughly $1,500–$5,500 installed, according to industry cost data from sources like HomeGuide and Angi, depending on the type — gas, electric heat pump, or solar. The bigger decision for Florida pool owners isn't just the upfront price; it's which type fits our climate and what it costs to run. In Florida's mild weather, an electric heat pump is often the sweet spot, solar is hard to beat on running cost given all our sun, and gas heats fastest but costs the most to operate. This guide compares all three.
Key takeaways
- Pool heaters run about $1,500–$5,500 installed; gas, heat pump, and solar differ in price and running cost.
- Electric heat pumps are the Florida sweet spot — efficient in our mild climate, cheap to run.
- Solar costs more upfront but is essentially free to operate given Florida's sun.
- Gas heats fastest but costs the most to run, suiting occasional quick heating.
- A heater extends the comfortable swim season into Florida's cooler months.

What pool heaters cost
Pool heaters are priced by type, with installation on top. Here's the 2026 picture from HomeGuide's pool heater cost data:
| Type | Typical installed cost | Running cost |
|---|---|---|
| Gas (natural gas or propane) | ~$1,500–$4,000 | Highest (fuel) |
| Electric heat pump | ~$2,000–$5,500 | Low (very efficient in FL) |
| Solar pool heating | ~$2,500–$7,000 | Lowest (essentially free) |
A worked example: adding an electric heat pump to a typical Orlando backyard pool lands in the low-to-mid four figures installed and costs relatively little to run in our warm climate. A solar system costs more upfront but has almost no operating cost. Match the type to how you'll use the pool and your tolerance for upfront vs. ongoing cost.
Gas vs. heat pump vs. solar
Each type works differently:
- Gas heaters burn natural gas or propane to heat water fast, regardless of air temperature. The upside is speed — they'll heat a pool quickly for a weekend. The downside is high running cost from fuel, so they suit occasional, on-demand heating rather than keeping a pool warm all season.
- Electric heat pumps pull heat from the surrounding air and transfer it to the water. They're slower to heat than gas but far cheaper to run, and they shine in warm climates because there's plenty of ambient heat to draw from — which makes Florida nearly ideal for them.
- Solar pool heating circulates pool water through roof-mounted panels warmed by the sun. The upfront cost includes the panels, but the running cost is essentially zero, and Florida's abundant sun makes it highly effective.
Which suits Florida best
Florida's climate tilts the choice in a clear direction for most pool owners. Because heat pumps draw from warm ambient air, and Florida has plenty of it most of the year, an electric heat pump is the efficient default — reasonable to run and well-matched to the mild conditions. It keeps a pool comfortable through the cooler months without the fuel bills of gas.
Solar is the other strong Florida pick if you have suitable, sunny roof space — the highest upfront cost but the lowest running cost, and it leans on the same abundant sun that makes residential solar productive here. Gas earns its place for owners who want to heat a pool fast and occasionally (a cold-snap weekend) and don't mind the running cost. The wrong fit is using a gas heater to keep a pool warm all winter — that's where the fuel bills sting.
Running costs matter most
Here's the key insight: with pool heaters, the running cost often matters more than the purchase price, because you'll pay it every month you heat the pool. A gas heater that's cheaper to buy can cost far more over a few seasons than a heat pump that's pricier upfront but sips energy. Solar flips it entirely — higher to install, almost nothing to run.
So frame the decision over the life of the heater, not just the install quote. If you'll heat the pool regularly, a heat pump or solar usually wins on total cost; if you only heat occasionally, gas's higher running cost matters less. The federal ENERGY STAR program is a neutral reference on efficient pool equipment. A pool service can also right-size and advise based on how you actually use the pool.
Sizing and maintenance
Two practical points round out the decision. Sizing matters — a heater (or solar array) too small for your pool's surface area will struggle to reach temperature, while an oversized one wastes money. Sizing depends on pool size, how warm you want it, and whether you use a pool cover (which dramatically cuts heat loss and running cost — the single best efficiency add-on for any heated pool).
Maintenance protects the investment. Florida's pool chemistry, if neglected, causes scale and corrosion that shorten a heater's life — the same water balance that protects a pool's surface protects the heater. Keep chemistry balanced (the foundation of avoiding problems like a green pool), and a heat pump or gas heater should last 8–12 years, solar longer.
Where to start
Start by deciding how you'll use the pool — occasional quick heating or keeping it warm through the season — and check your roof for solar suitability. Our pool service directory and Orlando city page list local pool companies, with more across the full directory. Compare the types on total cost (upfront plus running), size the heater to your pool, add a cover to cut running cost, and keep chemistry balanced so the heater lasts.
FAQ
How much does a pool heater cost in 2026? Industry cost data puts pool heaters around $1,500–$5,500 installed depending on type. Gas heaters run roughly $1,500–$4,000, electric heat pumps $2,000–$5,500, and solar pool heating $2,500–$7,000 including panels.
What's the best pool heater for Florida? For most Florida pools, an electric heat pump is the sweet spot — it works efficiently in our mild climate and is cheap to run. Solar is excellent given Florida's sun if you have roof space; gas heats fastest but costs the most to operate.
Which pool heater is cheapest to run? Solar is cheapest to operate (essentially free once installed), followed by heat pumps, which are very efficient in Florida's warm air. Gas heaters cost the most to run because of fuel prices.
How long does a pool heater last? A heat pump or gas heater typically lasts about 8–12 years with maintenance, while solar heating systems often last 15–20 years. Pool chemistry and upkeep affect lifespan, as scale and corrosion shorten it.
Is a pool heater worth it in Florida? For many, yes — it extends the comfortable swim season into the cooler months when Florida pools get chilly. A heat pump or solar system keeps running costs reasonable, which is what makes year-round use practical.
