The CorrectTech 4.0 kW Flo Thru heater is designed for compatible heating applications where a 12-1/2 inch by 2 inch, 240 volt heater assembly is needed. A Flo Thru heater is useful because it provides direct in-line heating while matching installations that require this more compact body size and supported platform format.

This version is especially useful when the original setup depends on the CorrectTech heater arrangement rather than a more standard 15 inch body style. Matching the correct heater dimensions helps preserve cleaner fit and more dependable replacement performance.

The C2550-2300ET is a practical replacement when a compatible Hydro-Quip-related system needs a 4.0 kW CorrectTech Flo Thru heater to restore reliable heating performance.

  • 12-1/2 inch by 2 inch, 240 volt configuration
