Heatrae Sadia 95612720 Combined Thermostat & Thermal Cut-out Assembly

The Heatrae Sadia 95612720 Combined Thermostat & Thermal Cut-Out Assembly is a genuine replacement spare designed for use in direct unvented hot water cylinders. Supplied by Heatrae Sadia, part of the Baxi group, this safety-critical component provides accurate temperature regulation and essential overheat protection for Megaflo and compatible unvented systems.

If your cylinder is overheating, not reaching set temperature, or repeatedly tripping the reset button, replacing the thermostat and thermal cut-out assembly may restore safe and reliable operation.

What Does This Part Do?

This combined unit performs two key functions:

✔ Temperature Control Thermostat – Regulates water temperature to the desired set point for consistent hot water performance.
✔ Manual Reset Thermal Cut-Out – Cuts power to the immersion heater if unsafe temperatures are detected, helping prevent damage to the cylinder and ensuring compliance with unvented safety standards.

By integrating both functions into one assembly, part 95612720 ensures efficient operation while maintaining critical system protection.
