About this heater

The Balboa BP Series G7415 is a 4.0kW, 230V flow-through heater assembly designed for spas using Balboa M7 control systems. This OEM replacement heater delivers reliable 4000-watt heating performance through a compact flow-through design, featuring a 24-inch sensor for precise temperature monitoring. The 230V configuration provides efficient heating for medium to large spa applications.

At Bubbles Supply, we guarantee this Balboa heater is an exact fit for your spa system, with same-day shipping to get your spa running quickly. Every G7415 heater comes backed by our comprehensive 1-year warranty for complete peace of mind. This flow-through design requires proper water flow during operation—ensure your circulation pump is functioning correctly before installation and never energize the heater without adequate water flow through the element.

Common symptoms this part fixes

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

  • Spa not heating or heating very slowly
  • OH (overheat) fault code displayed on topside controller

Before you buy — quick checklist

  • Confirm your spa runs a Balboa M7 control system — this heater is not universal
  • Verify your spa is wired for 230V service before ordering
  • Check the kW rating of your existing heater — this is a 4.0kW unit and must match your system's configuration
  • Inspect the sensor length on your current heater — this unit uses a 24-inch sensor
  • Ensure your circulation pump is functioning before replacing the heater, as flow issues can cause repeated heater failures
  • Check heater union size on your existing plumbing before removal to confirm compatibility

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