About this heater

This HydroQuip 5.5kW 230V low flow heater assembly is designed for Gatsby spa systems requiring reliable heating performance. The E2550-0300ET-G delivers consistent 5.5 kilowatt output at 230 volts, engineered specifically for low flow applications where water circulation rates are reduced.

When your spa displays heater fault codes or struggles to maintain temperature, this OEM HydroQuip replacement restores proper heating function. At Bubbles Supply, we guarantee this heater assembly provides an exact fit for your system, backed by our comprehensive 1-year warranty and same-day shipping on in-stock orders. Professional installation is recommended to ensure proper electrical connections and system compatibility—always verify voltage requirements and flow specifications match your spa's configuration before installation.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Spa displaying HH (high heat) fault code

Before you buy — quick checklist

  • Confirm your spa is a Gatsby system running a HydroQuip control board
  • Verify your existing heater is rated 5.5kW at 230V — do not substitute a different wattage without verifying system compatibility
  • Confirm your system is a low flow configuration before ordering — this heater is not interchangeable with standard flow heater assemblies
  • Note the fault codes displayed on your control panel (HH or OH) to ensure a heater replacement addresses the root cause
  • Check for scale buildup or restricted water flow before installation — a clogged heater tube can cause repeat failures

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