About this heater element

This HydroQuip 5.5KW titanium heater element (part #25-4034-TI) delivers reliable heating performance for 120/240V spa systems. The flow-through design with 1.375" fitting and 10.63" length makes it a direct replacement for worn or failed heating elements in HydroQuip-equipped hot tubs and spas.

Built with corrosion-resistant titanium construction, this dual-voltage element handles both residential 120V and commercial 240V applications at 5.5KW output. At Bubbles Supply, we guarantee an exact fit with your original equipment, plus every heater element ships same-day and comes backed by our full 1-year warranty. Professional installation recommended for proper electrical connections and system safety—always verify voltage compatibility and turn off power at the breaker before beginning any heater element replacement.

Common symptoms this part fixes

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

  • Spa not heating or heating very slowly
  • HH or OH error code on control panel
  • Heater element visibly corroded, scaled, or failed
  • Spa water temperature not reaching setpoint
  • Element reads open circuit on continuity test

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

Before you buy — quick checklist

  • Confirm your spa runs a HydroQuip heater assembly before ordering
  • Verify your system operates at 120V or 240V — do not assume
  • Measure your existing element length (this unit is 10.63") and fitting diameter (1.375") before purchasing
  • Test your existing element with a multimeter — confirm open circuit before replacing
  • Check whether your spa controller is throwing an HH or OH fault, as this can also indicate a faulty sensor rather than a failed element

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