About this heater

This 5.5kW 230V flow-through heater assembly from Balboa delivers reliable heating performance for mid-size residential spas and hot tubs. The compact 2" x 15" M7 frame design with flow-through configuration ensures efficient heat transfer while the convenient BP plug-and-click connector simplifies installation and service. Built to Balboa's OEM specifications, this heater effectively resolves common heating issues including HH (high limit) and OH (overheat) error codes.

Bubbles Supply guarantees this heater is an exact fit replacement for your Balboa heating system, backed by our comprehensive 1-year warranty and same-day shipping on in-stock orders. The 5500-watt 230V power rating provides optimal heating capacity for most residential applications.

Common symptoms this part fixes

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

  • Spa not heating
  • HH error code (high limit fault)
  • OH error code (overheat / thermal cutout tripped)
  • Water temperature not reaching set point
  • Heater element failure — spa runs but no heat gain
  • Spa control board showing heater-related fault codes

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

Before you buy — quick checklist

  • Confirm your existing heater is rated 230V — do not install on a 120V system
  • Verify your current heater measures 2" x 15" (M7 frame) before ordering
  • Check that your spa control system uses a BP plug-and-click heater connector
  • Confirm your spa requires a 5.5kW / 5500W heater — check the label on your existing unit
  • Inspect heater unions and surrounding plumbing for cracks or deterioration before installation
  • If you are getting HH or OH codes, also check your high-limit sensor and flow switch — a faulty sensor can trigger codes even with a good heater

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