    I am trying to fit a tank thermostat to my hot water tank. it is an immersion tank and seems to heat up extremely hot so I trying to control the temperature with the tank stat. It is a siemens stat and the immersion is controlled by a mechanical timer switch (make unknown sorry!) is this a simple fix?

    Do you mean to control the immersion heater or

    The heating by a boiler?

    The immersion heater already has a thermostat inside it. Maybe you should test and change that if it is faulty.

    or adjust it down.

    turn the power off, and remove the top of the heater. (usually a nut)

    Inside should be a dial, maybe set at 65. You could turn it down to 60.

    or as said it could be faulty.

    To test, after the heater has been on for a while and water very hot, listen to the tank with the heater on.

    Does it sound like a kettle, either constantly or intermittantly. If it does it's faulty.

    Replace / set the immersion heater thermostat.

    You should be able to change the setting and heat the thermostat switch
    on and off.
