Pool Heaters & Heat Pumps

Shop Pool & Spa Heaters by Fuel Type

Pool heating can be powered by natural gas, propane, or electricity. Gas heaters are commonly chosen when fast heat-up is important, especially for spas and occasional pool heating. Heat pumps are often used for efficient temperature maintenance when ambient conditions are favorable. Electric resistance heaters are generally used for smaller water volumes or specific spa applications where adequate electrical service is available.

Natural Gas Pool Heaters

Natural gas heaters are widely used for residential and commercial pools where a sufficient gas supply is available. Popular families include Pentair MasterTemp, Hayward Universal H-Series, Jandy JXi and JXiQ, and Raypak digital and AVIA heaters. The gas line and meter must be capable of supporting the selected BTU input.

Propane Pool Heaters

Propane heaters offer similar heating performance where natural gas is not available. Always order the correct fuel version for the property. Natural-gas and propane models use different fuel components, and conversion should only be performed when the manufacturer provides an approved procedure or conversion kit for that exact heater.

Pool Heat Pumps

Heat pumps transfer heat from the surrounding air into the pool water. They can provide efficient temperature maintenance but generally heat more slowly than high-BTU gas heaters. Performance depends on outdoor temperature, humidity, pool size, and desired set point. Selected models also provide cooling capability.

How Many BTUs Does My Pool Heater Need?

Heater sizing depends on pool and spa volume, desired temperature rise, climate, wind exposure, cover usage, and how quickly you want the water to heat. A larger BTU heater can reduce heat-up time, but the fuel supply, plumbing, electrical service, and installation conditions still have to support the unit.

Residential vs. Commercial Pool Heaters

Commercial pools, hotels, apartments, schools, aquatic facilities, fitness centers, and municipalities may require ASME-rated equipment, higher heating capacity, redundant systems, or code-specific venting and controls. Pool Supply Depot can help source commercial heaters and coordinate nationwide freight for qualifying projects.

Pool Heater Replacement

Replacing an existing heater is not always a direct swap. Plumbing height, gas connection, vent location, electrical requirements, automation wiring, heat-exchanger material, and equipment footprint can vary between brands and generations. Before ordering, compare the complete model and installation requirements.

Heater Automation Compatibility

Many modern pool heaters can integrate with compatible automation systems for scheduled heating, spa temperature control, and remote operation. Compatibility depends on the heater and control platform. If you are upgrading the entire equipment pad, shop our Pool Automation Systems and Variable-Speed Pool Pumps.
