Before you buy — quick checklist

  • Confirm your spa operates on 240V — this heater is not compatible with 120V systems
  • Locate your existing heater's part number on the heater tube or control box label and verify C2550-0056 is a direct match
  • Check the union size and connection style on your current heater plumbing before ordering
  • Inspect the heater manifold and pressure switch ports to ensure they match this assembly's configuration
  • Verify your spa's control system (pack brand and model) is rated for a 5.5KW heater load

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