Raypak Pool & Spa Heaters

A Raypak pool heater is the difference between a pool you use three months a year and one you swim in from spring through late fall. Whether you're heating a spa to a fast 104°F on a cool evening or holding a full inground pool at a comfortable 84°F for the season, Raypak's gas heaters and inverter heat pumps deliver reliable, efficient warmth that pays you back in swim days. This collection covers the full Raypak lineup — natural gas, propane, and electric heat pump — from compact 85K BTU units up to commercial-grade 406K BTU ASME models.

Choose a gas heater when you want the fastest heat-up and on-demand warmth regardless of outdoor temperature — Raypak's electronic-ignition and digital models in 150K, 266K, 336K, and 399K BTU sizes suit everything from a small spa to a large inground pool. Header material matters for longevity: polymer headers resist pool-chemistry corrosion for most residential installs, while cupro-nickel and titanium options stand up to salt systems and heavy bather loads. Prefer lower operating cost? The Raypak Crosswind inverter heat pump pulls warmth from the air and delivers it at a fraction of the running cost of gas — ideal for climates where you're extending, not fighting, the season. Match BTU output to your pool's surface area and your local climate, and size up if you want faster recovery.

Keep your heater running for years with our pool heater replacement parts, and compare the full field across brands in our pool heaters and Hayward heaters collections. Proper water chemistry protects your heat exchanger, so pair any heater with our pool water testing supplies. For sizing math and efficiency ratings, the U.S. Department of Energy's pool heater guide is the best neutral reference on gas vs. heat pump vs. solar, and the manufacturer's own Raypak resource site has model-specific spec sheets and manuals.
