Natural Gas Pool Heaters

Natural gas heaters heat a pool or spa quickly regardless of outside temperature, which makes them the go-to choice for spa heating and year-round swimming. Shop natural gas pool heaters from Pentair (MasterTemp, Max-E-Therm, ETi), Raypak, Hayward (H-Series, Universal H-Series) and Jandy (JXi, JXiQ), from 150,000 to 400,000 BTU.

Size your heater by pool and spa volume, how quickly you want to heat, and the length of your swimming season. Our Pool Heater Calculator can help. Gas line size and meter capacity also matter, so confirm your gas supply with a licensed plumber before installation.
