Balboa BP100 15" 4.0kW Flo-Thru Heater (26-G7413-K)

Balboa BP100 15" 4.0kW Flo-Thru Heater (26-G7413-K) is a replacement heater for compatible BP100 systems where the original assembly must be matched by configuration as well as output. With a 4.0kW rating and 15" heater format, it is designed to integrate into a specific Balboa plumbing, control, and electrical layout.

BP100 systems are compact control platforms, so the heater assembly is an integrated part of the overall equipment layout rather than an interchangeable stand-alone component. Selecting the correct heater helps preserve the relationship between circulation flow, control logic, electrical load, and the physical space available in the equipment bay.

The 4.0kW rating is a common full-size spa heating specification, but output alone does not determine interchangeability. Two 4.0kW heaters may use different control families, sensor arrangements, wiring interfaces, mounting details, or plumbing positions. Verifying those details before installation helps prevent an otherwise similar-looking heater from becoming an incorrect replacement.

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-G7413-K can help restore dependable water heating, steadier temperature maintenance, and the day-to-day comfort expected from a properly operating spa.
