Before you buy — quick checklist

  • Confirm your spa's supply voltage is 230V — do not install on a 115V system
  • Locate the existing heater's model or part number and verify C2550-0011 is a direct match
  • Measure your current heater tube dimensions (2" x 15") to confirm physical fit
  • Check plumbing union size and configuration before ordering to avoid fitment issues
  • Clear any active fault codes after replacement — HH and OH codes may require a manual reset on the topside controller
  • Professional electrical work may be required depending on your local code — verify before starting

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