So several months ago the old immersion heater thermostat tripped out, it was visibly heat damaged and proved bad after a quick continuity check and test in a kettle. After a quick trip to Screwfix I was only £10.79 lighter (no this isn't an advert!) for the 18'' dual safety thermostat.

Well I think I have got to the bottom of it. It looks like 65C on the mechanics of the thermostat is actually MUCH hotter. I dialed it back by 5C at a time, and found that it didn't trip, and found that the volume of the immersion heater 'singing' reduced. I put the metal cover back on so all is safe and well, and is still doesn't trip.

Can an immersion heater overheat?
Its possible of course, the supply cable could be too small or the Kw of the immersion heater has been increased and its drawing to much power making it overheat. You could have earth leakage problems, but that would have probably tripped your RCD or ELCB by now. That is of course if you have one fitted. I would get the system checked out if your unsure, because unrestricted earth leakage is highly dangerous especially if you have no ELCB or RCD.
