About this heater

The Balboa G7412 is a 4.0kW flow-through heater assembly designed for Balboa spa systems requiring 230V power. This 2" x 15" M7-style heater features the convenient BP plug-n-click connector, eliminating hardwiring hassles during replacement. Built to OEM specifications, this genuine Balboa heater delivers reliable heating performance for your spa.

At Bubbles Supply, we guarantee this heater is the exact fit for your Balboa system, backed by our 1-year warranty and same-day shipping on in-stock orders. The flow-through design ensures efficient heat transfer while the compact 15" length fits standard spa equipment bays. Before installation, verify your spa's voltage requirements match the 230V specification and ensure proper electrical connections are made by a qualified technician.

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 on control panel
  • OH error code (nuisance overheat caused by failed element)
  • Water stays cold despite pump running
  • Heater element burned out or visibly corroded

Before you buy — quick checklist

  • Confirm your spa control system is a Balboa board with M7 heater port compatibility
  • Verify your pack accepts the BP plug-n-click connector — do not assume all Balboa packs use this style
  • Confirm 230V supply voltage at the equipment bay before ordering
  • Measure your existing heater tube: must be 2" diameter and 15" in length to fit the same footprint
  • Check for scale buildup or flow restrictions before install — a restricted flow switch will cause the new heater to fault immediately
  • Have a licensed electrician handle final wiring connections per local code

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