Description
The Therm 4.0 kW flo thru heater is designed for compatible 2 inch by 15 inch 240 volt applications that use a dual sensor system. Heaters with application-specific sensor support are useful because they help preserve the control logic and monitoring setup that the spa was originally built around.
This replacement is especially useful when the original heater has failed, is heating inconsistently, or needs replacement while maintaining compatibility with a dual-sensor-equipped system. Matching the correct configuration helps reduce installation problems and supports more predictable operation.
It is a practical service part when reliable heat restoration depends on keeping the heater aligned with the system’s dual sensor design.
