Immersion Heater Rod Thermostats Tripping Off.

Has anyone had incidences of rod 'stats tripping off by the back-up safety cut off with no apparent reason. The copper cylinders had no secondary heating that could overheat the water such as a coil heated by gas or oil.

  • First guess would be that the immersion's normal thermostat isn't quite right - either stuck in the 'on' position or a bit slow in switching off when max temperature is reached.

    Second guess would be the safety-cut out is a bit over sensitive and is cutting out at too low a temperature.

    Third guess would be that inappropriate parts have been used - occasionally (especially if 'top' entry) if the 'stats have the wrong lengths they can be sensing different parts of the tank - e.g. the overheat looking at the very top but the main thermostat sensing somewhat lower (and thus usually cooler) part.
