The Case for Gas

Fastest Heat.
Any Weather.

Unlike heat pumps that struggle when temperatures dip below 50°F, a gas heater generates heat directly — burning natural gas or propane to bring your pool or spa to temperature in a fraction of the time. In Northeast Florida, where you want year-round flexibility, gas is the practical choice.
Your outdoor investment deserves to be used. Gas heating puts you in control of your schedule, not the forecast.

What We Do

Expert Service,
Start to Finish

New Installation

Complete gas heater installation including gas line runs to your equipment pad, proper sizing for your pool volume, and code-compliant connection. We handle everything from permit to first light.

Diagnostics & Repair

From pilot light failures and error codes to heat exchanger issues and burner assembly problems — our technicians diagnose fast and repair right the first time, minimizing your downtime.

Annual Maintenance

Yearly tune-ups that extend heater life and ensure safe operation — including burner inspection, heat exchanger check, gas connection testing, and venting verification. Best done at season start.

Gas Line Work

New gas line extensions, pressure testing, leak detection, and code-compliant upgrades. As Master LP Licensed contractors, we handle all gas infrastructure with full regulatory compliance.

Pool & Spa Combos

Setup or optimize combination systems that serve both your pool and spa from one heater using a bypass valve configuration. We assess your plumbing and recommend the most efficient layout.

Commercial Properties

Hotels, resorts, and community pools have specific reliability demands. We service commercial gas heating systems with the urgency and expertise that keeps your amenities operating continuously.

Know the Warning Signs

Don’t Wait Until It Stops Working

Early detection of heater problems prevents a minor service call from becoming an expensive replacement. If you recognize any of these signs, contact AEI ProGas before the issue worsens.

Schedule Inspection

How quickly can a gas heater heat my pool?

What is the difference between a gas pool heater and a heat pump?

A gas heater burns natural gas or propane to generate heat directly, making it extremely fast and effective regardless of outdoor air temperature. A heat pump, by contrast, extracts heat from the surrounding air and transfers it to the water, which makes it more energy-efficient in warm climates but significantly slower and less effective when air temperatures drop below 50 degrees Fahrenheit. For Northeast Florida homeowners who want year-round use and rapid heating, a gas heater is often the more practical choice.

Can I use a gas heater for both my pool and my spa?

Yes. Many systems are designed with a combination heater that serves both the pool and the spa. A bypass valve system allows you to direct the heated water to whichever body of water you want to use. Our technicians can assess your existing plumbing and recommend the most efficient setup for your specific configuration.

Do gas pool heaters work with both natural gas and propane?

Most gas pool heaters are available in natural gas and propane (LP) versions, and some models can be converted between the two. AEI ProGas is certified to work on both LP and natural gas systems, so we can install and service whichever fuel type your property uses.

How often should a gas pool heater be serviced?

What should I do if I smell gas near my pool heater?

If you detect a gas odor near your pool equipment pad, turn off the gas supply at the shut-off valve immediately, move away from the area, and call AEI ProGas from a safe distance. Do not attempt to inspect or restart the unit yourself. Gas leaks near outdoor equipment require immediate professional attention.

Gas heaters are the fastest pool heating option available. The exact time depends on the size of your pool, the starting water temperature, and the BTU rating of the heater. As a general rule, a properly sized gas heater can raise pool water temperature by 1 to 2 degrees Fahrenheit per hour. For a spa, a high-output gas heater can bring the water to a comfortable soaking temperature in as little as 15 to 30 minutes.A gas heater burns natural gas or propane to generate heat directly, making it extremely fast and effective regardless of outdoor air temperature.

We recommend a professional inspection at least once a year, ideally at the start of the swimming season. Annual service includes inspecting the burner assembly, checking the heat exchanger for cracks or corrosion, verifying all gas connections are secure and leak-free, and confirming that the venting and exhaust are clear and functioning properly.
