Can someone please tell me what the TCO (Termal Cut Out) monitors. By this I mean does it monitor the water temperature in the tank or does it monitor the temperature of the heating rods? Or something else?
The reason I ask is that I am trying to determine if my overheat problem is due to limescale? i.e. perhaps that water temp is not that high but the heating rods are covered in limescale and as such are getting up to cut out temperature without heating the water enough.
Cheers
