Balboa 15" 3.0kW M7 Dual Sensor Flo-Thru Titanium Heater (26-55626-K)

Balboa 15" 3.0kW M7 Dual Sensor Flo-Thru Heater (26-55626-K) is engineered for compatible M7 spa systems that rely on dual-sensor monitoring across the heater assembly. The 3.0kW rating provides a specific heating capacity that must be matched to the original control system and electrical configuration to maintain proper operation.

Balboa’s dual-sensor approach allows the control system to monitor conditions associated with water moving through the heater rather than relying on a simple one-point mechanical switching method. When the correct heater is paired with the proper control system and circulation setup, this arrangement supports more consistent heater management and helps the system respond appropriately during normal heating cycles.

The 3.0kW output provides a specific balance between heating capacity and electrical demand for systems designed around this rating. Replacing it with a heater of a different wattage can affect recovery characteristics and electrical loading, so the original specification should be maintained unless the spa manufacturer explicitly approves another configuration.

Proper fitment begins with verification. Compare the existing heater’s part number, length, rated output, sensor or control connections, plumbing orientation, and electrical requirements before ordering. Spa heaters are not universally interchangeable, and taking a few minutes to confirm these details can reduce installation delays, unnecessary returns, and repeat service calls.

Once correctly matched and installed, the Balboa 26-55626-K can help restore dependable water heating, steadier temperature maintenance, and the day-to-day comfort expected from a properly operating spa.
