About this heater element

The ProAqua PA-25-4034-BI-TI is a premium titanium heater element designed for spas requiring a 5.5kW, 240V flo-thru heating system. This double-bend M7 configuration fits hot tubs equipped with ProAqua heating assemblies and other compatible systems that use this specific element design. The titanium construction provides superior corrosion resistance and longevity compared to standard heating elements, making it ideal for demanding spa environments.

At Bubbles Supply, we guarantee an exact fit for your spa heating system and offer same-day shipping on all in-stock heater elements. Every ProAqua heater element comes backed by our comprehensive 1-year warranty for complete peace of mind. Before installation, always verify your spa's voltage requirements and ensure power is completely disconnected. This element requires proper flow-through operation and should only be installed by qualified technicians familiar with spa electrical systems.

Common symptoms this part fixes

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

  • No heat or spa not reaching set temperature
  • Heater error codes on topside control panel (HH or OH fault)
  • Spa heating slowly or losing heat over time
  • Visibly corroded, pitted, or failed heater element
  • Ground fault or nuisance GFCI tripping caused by degraded element
  • Spa water causing element corrosion due to aggressive chemistry

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

Before you buy — quick checklist

  • Confirm your spa runs a 240V flo-thru heating assembly — this element is not for 120V systems
  • Verify your existing heater manifold accepts an M7 double-bend element configuration
  • Check that your current heater assembly is a ProAqua unit or confirmed compatible manifold before ordering
  • Inspect heater manifold housing for cracks or damage — a failed element sometimes masks a damaged manifold that also needs replacement
  • Confirm titanium element is appropriate for your water chemistry — titanium is recommended for saltwater or ozone systems but verify compatibility with your specific setup
  • Have your spa's full error code history on hand before ordering to rule out a control board or sensor fault rather than the element itself

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