About this heater element

The HydroQuip 3.6KW 230V Heater Element (12-0113G-K) is a genuine OEM flo-thru heating element designed for HydroQuip spa systems requiring 3600-watt, 230-volt operation. This titanium construction element delivers reliable, efficient heating performance while resisting corrosion and mineral buildup that can plague lesser materials. Whether you're dealing with "HH" high limit or "OH" overheat error codes, this exact replacement restores proper spa temperature control.

Built to HydroQuip's original specifications, this heating element comes with our exact fit guarantee, ships same-day from our Canadian warehouse, and includes a full 1-year warranty for complete peace of mind. The titanium construction ensures long-lasting durability in harsh spa water conditions while the flo-thru design maximizes heating efficiency. Always verify your existing element's specifications and voltage requirements match before installation, and ensure proper water flow through the heater housing during operation.

Common symptoms this part fixes

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

  • HH (high limit) error code on spa display
  • OH (overheat) error code on spa display
  • Spa not heating or holding temperature
  • Heater element burned out or visibly failed
  • Spa water staying cold despite pump running
  • Tripped GFCI or breaker traced to heater circuit

Before you buy — quick checklist

  • Confirm your spa control system is HydroQuip brand — check the control box label
  • Verify your existing heater element is rated 3.6KW at 230V — do not install a 230V element on a 120V system
  • Check whether your HH or OH error is truly an element failure versus a faulty high-limit sensor or flow issue before ordering
  • Inspect the heater housing/manifold for cracks or scale buildup — a new element won't fix a damaged housing
  • Ensure water flow through the heater is confirmed working before replacing the element — dry firing will destroy a new element immediately

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