What is a thermostat & thermal cut-out assembly?

A combined thermostat and thermal cut-out assembly controls water temperature while providing a built-in safety mechanism that disconnects power if overheating occurs. It is a critical component in unvented hot water systems such as Megaflo cylinders.

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.
