About this heater element

This HydroQuip 5.5KW 120V flo-thru heater element (part #20-3053) replaces worn heating elements in spas equipped with HydroQuip heating systems. The titanium construction and double-bend flo-thru design deliver reliable 5500-watt heating performance at 120 volts, restoring your spa's ability to reach and maintain target temperatures efficiently.

As an OEM HydroQuip replacement part, this heater element delivers the exact fit and specifications your spa was designed for. At Bubbles Supply, we guarantee precise fitment and back every heater element with our 1-year warranty. Most orders ship same-day from our Canadian warehouse. Always verify your existing element's wattage, voltage, and connection type before ordering to ensure proper compatibility with your spa's control system.

Common symptoms this part fixes

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

  • Spa water not heating
  • Spa takes too long to reach set temperature
  • Heater cycling on and off without reaching target temp
  • OH (overheat) fault code on control panel
  • HH (high heat) fault code on control panel
  • Burnt or corroded element causing tripped breaker

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing element is rated 5.5KW at 120V — do not assume based on spa size alone
  • Verify your spa uses a HydroQuip heating system before ordering
  • Check the element's terminal configuration and connection type matches your heater housing
  • Inspect the heater housing for cracks or corrosion — a failed element can sometimes damage the housing too
  • Confirm whether your spa control system throws an HH or OH fault to rule out a sensor issue rather than a failed element

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