About this heater

The Balboa BP Series 4.0KW 230V Flow Thru Heater G7432 is a premium titanium heating element designed for Balboa spa systems. This 4,000-watt heater operates on 230V power and features Balboa's innovative BP Plug-n-Click technology for simplified electrical connections. The titanium construction resists corrosion and provides superior heat transfer efficiency, making it an ideal replacement for worn or failed heating elements in compatible Balboa spa packs.

At Bubbles Supply, we guarantee this heater is an exact fit for your Balboa system and back it with our comprehensive 1-year warranty. Every genuine Balboa heater ships the same day when ordered before our cutoff time, getting your spa back to optimal temperature fast. This heater effectively resolves HH (high heat) and OH (overheating) error codes that indicate heating system failures. Professional installation is recommended to ensure proper electrical connections and optimal performance in your spa's heating circuit.

Common symptoms this part fixes

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

  • HH error code (high heat fault)
  • OH error code (overheating / thermal cutout tripped)
  • Spa water not heating or heating too slowly
  • Heater element failure — no heat output
  • Tripped GFCI or breaker traced to heater circuit
  • Spa control board displaying heater-related fault codes

Before you buy — quick checklist

  • Confirm your spa pack is a Balboa BP Series system — this heater uses the BP Plug-n-Click connector and will not mate with other Balboa series without adapter
  • Verify your existing heater is rated 4.0KW at 230V — check the label on the old heater tube or your spa pack documentation
  • Check whether your HH or OH fault is actually a failed heater element vs. a failed high-limit sensor or pressure switch — replace the correct component
  • Inspect heater unions and manifold connections for cracking or corrosion before install — replace seals or unions if worn
  • Confirm your spa's electrical supply is 230V/240V — this heater is not compatible with 120V systems
  • Take a photo of your existing heater's wiring before disconnecting — BP Plug-n-Click simplifies reconnection but documentation helps avoid errors

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