It's the question we hear most every fall in our Kendall store: "How much does it cost to install a pool heater in Miami?" Here's the honest breakdown for 2026 — real numbers, no surprises.

The short answer

For most Miami homes, a quality electric heat pump installed runs from $3,500 — including the unit, installation, and startup. Our current example: a Rheem CrossWind V, 118,000 BTU heat pump, fully installed for $3,650. Gas heaters are priced by quote, because the final cost depends mostly on your gas line.

Heat pump vs. gas heater: which fits Miami?

Heat pumps move heat from the air into your pool instead of burning fuel. In South Florida's warm climate they're the most efficient option we sell — low running cost, long life, and perfect for keeping a pool comfortable from October through spring. Larger models with inverter technology and heat + cool capability cost more up front.

Gas heaters (natural gas or propane) heat the water much faster — great for a spa you want hot in 30 minutes, or for heating a pool only on weekends. The trade-off: higher fuel cost every time it runs, and installation cost depends on how far the gas line has to travel.

What changes the final price?

• BTU size — a bigger pool (or a pool + spa combo) needs a bigger heater. Undersizing is the #1 mistake we see: a too-small heater runs forever and still can't keep up on a cool night.
• Electrical capacity — most heat pumps need a dedicated 240V circuit. If your panel needs an upgrade, that adds cost.
• Gas line distance (gas models) — the farther from the meter or tank, the more the installation costs.
• Equipment pad — a new concrete pad or plumbing rework adds to the job.
• Automation — connecting the heater to a system like Jandy AquaLink or Pentair IntelliCenter so you can heat the spa from your phone.

What does it cost to RUN?

A heat pump typically costs a fraction of gas per degree of heating — in our climate, it's the cheapest way to keep a pool swimmable all season. Gas wins on speed, not on the monthly bill. If you heat your pool regularly, the heat pump pays you back every single month.

When should you install?

Heater season in Miami is now. Install before the first real cold front and your pool stays ready all winter — wait until the first cold week and you'll be in line with everyone else who waited.
