The Therm 5.5 kW flo thru heater is designed for compatible Cal Spas applications using a 15 inch by 2 inch 240 volt format without a box assembly. Heaters in a no-box format are useful when the surrounding system layout does not require the added enclosure and the replacement needs to match that simpler configuration.

This replacement is especially useful when the original heater has stopped performing, failed electrically, or is no longer dependable and the system expects the no-box design. Matching the correct voltage, length, and application style helps reduce installation issues.

It is a practical service part when reliable heating needs to be restored in a compatible Cal Spas system without changing the original heater format.

  • Therm 5.5 kW flo thru heater for compatible Cal Spas applications
  • 15 inch by 2 inch format with 240 volt operation
  • Configured without a box assembly
  • Useful when the original heater is failed or inconsistent
