A heater assembly that includes the matching sensor arrangement can make a repair feel much more complete, and this Balboa M7 15 inch 5.5 kW Spa Heater Assembly is designed for compatible applications requiring 24 inch sensors. When both the heating body and the related sensing setup begin to feel unreliable, replacing them together is often one of the smartest ways to restore stable spa performance.

The included 24 inch sensors matter because they help preserve the relationship between the heater and the way the system reads its operating conditions. That can be especially helpful in applications where the existing sensing hardware is just as questionable as the original heater itself.

The 5.5 kW output gives this assembly stronger heating capability for compatible systems, while the M7 design helps keep the replacement aligned with the Balboa heater platform many owners already rely on. Those details work together to create a more dependable and more service-friendly repair path.

Installed in the proper M7 setup, this assembly helps restore stronger heat and a more complete sensing relationship, giving the spa a more confidence-inspiring operating feel overall.

  • Heater assembly with 24 inch sensors for compatible Balboa M7 systems
  • 5.5 kW output helps restore stronger heating performance
  • Helps replace both heating and sensor-related wear in one repair
  • Useful when original heater and sensor performance decline together
  • Improves overall system confidence and daily comfort
