Before you buy — quick checklist

  • Confirm your spa runs on 115V — this heater is NOT compatible with 240V systems
  • Verify your current heater is a HydroQuip unit and matches the PH301-15UV form factor
  • Check that your existing plumbing union sizes match this heater's inlet and outlet connections before ordering
  • Confirm your spa control system supports a 1.5KW heater element — do not substitute a higher-wattage unit without verifying compatibility
  • Inspect the vacuum switch wiring harness on your old heater to ensure the connector style matches

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
