Before you buy — quick checklist

  • Confirm your spa uses a HydroQuip heating system — check your control box or pack label
  • Verify your spa runs on 240V before ordering — do not install on 120V systems
  • Confirm the slide-style heater format matches your existing heater mounting (slide-in vs. threaded union style)
  • Note your existing heater's kW rating — this unit is 5.5kW and must match your system's heater output spec
  • Disconnect all power at the breaker before beginning removal of the old heater
  • Inspect heater tube, o-rings, and manifold for corrosion or damage before installation

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