About this heater element

This HydroQuip 3.0KW 230V flo-thru heater element delivers reliable heating performance for spas equipped with HydroQuip heating systems. The titanium construction resists corrosion and scaling while providing efficient heat transfer at 3000 watts of heating power on 230-volt electrical systems. This OEM replacement element restores proper water heating when your spa runs cold or displays heating error codes.

At Bubbles Supply, we guarantee an exact fit with authentic HydroQuip parts, backed by our 1-year warranty and same-day shipping on in-stock items. The flo-thru design integrates directly into your existing heater housing for seamless operation. Before installation, verify your spa's voltage requirements and heating element wattage to ensure proper compatibility with your system's electrical specifications.

Common symptoms this part fixes

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

  • Spa water stays cold or won't heat
  • Spa displays HH or OH error code
  • Heater trips breaker on startup
  • Spa heats slowly or inconsistently
  • Burned or corroded element on inspection

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

Before you buy — quick checklist

  • Confirm your heater housing is rated for a 3.0KW element — swapping wattage on an incompatible housing is a fire hazard
  • Verify your spa runs on 230V, not 120V
  • Check your existing element's length and diameter before ordering — flo-thru elements are not universal
  • Inspect the heater housing for cracks or corrosion before installing a new element — a bad housing will kill the new element fast
  • Confirm the 12-0104F-K part number against your current element or heater assembly label

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