Extend your swimming season with energy-efficient pool heating solutions. Maintain the perfect water temperature for comfortable, enjoyable swims, day or night, all year round.
If you want to extend your swimming season or enjoy comfortably warm water 365 days a year investing in a pool heater is the single best upgrade you can make for your backyard oasis.
Don't limit your pool usage to just two or three months in the summer. A reliable heating system lets you open your pool earlier in the spring and keep it open well into late autumn or even year-round in milder climates.
Gas heaters typically last 7 to 10 years, with heat exchanger corrosion (due to low pH or salt cell back-siphoning) being the primary failure mode.
Heat pumps typically last 10 to 15 years because their titanium heat exchangers are immune to chemical corrosion, making electrical components and compressors the primary wear points.
Gas heaters (Natural Gas and Propane) are significantly faster. A standard 400,000 BTU gas heater can raise pool water temperature by 1°F to 2°F per hour, making them ideal for quick, on-demand heating or spa heating. Heat pumps are slow and steady, raising water temperature by only 0.25°F to 1°F per hour under optimal conditions.
Standard heat pumps extract heat from the surrounding air, losing efficiency rapidly when air temperatures drop below 50°F to 55°F (though low-ambient/chiller models can operate lower).
Gas heaters (NG and LP) operate at full efficiency regardless of outside air temperature, making them the only reliable choice for sub-freezing winter heating.
Heat pumps are by far the most energy-efficient for maintaining a consistent daily temperature, operating at a Coefficient of Performance (COP) of 5.0 to 6.0 (yielding $5 to $6 worth of heat for every $1 of electricity).Natural gas is the middle option, while propane is almost always the most expensive per BTU generated due to fuel delivery costs.
Unlike gas heaters, which only need standard 120V power to ignite the control board and spark ignition, a pool heat pump compressor requires a dedicated 220V/240V circuit (typically 40 to 60 amps), which may require an electrical panel upgrade.
