A FloThru heater helps provide integrated water heating in a compatible spa system, and this Gecko Heat.Wav unit is designed in a 15 inch by 2 inch format with 4kW output for 230 volt IN.Yj applications and includes a sensor using the 0613-421009 reference. When a heater becomes unreliable, the spa can lose the consistent warming performance it should provide.

The inclusion of the matching sensor gives this heater practical value because replacement heating components work best when the heater body and sensing arrangement are aligned with the intended control platform. A properly selected heater helps support cleaner integration, steadier heating performance, and more dependable overall operation.

This type of component is especially useful when the existing system is built around Gecko IN.Yj controls and a direct heater replacement is preferred over adapting a generic unit. That helps reduce compatibility issues during service.

Installed in the proper application, this FloThru heater helps support dependable water heating and contributes to cleaner overall spa-system performance.

  • 4kW FloThru heater for compatible 230 volt Gecko IN.Yj spa applications
  • 15 inch by 2 inch format supports intended replacement fit
  • Includes sensor for aligned control-platform integration
  • Helps support dependable spa heating performance
  • Improves replacement accuracy and system reliability
