"The actual element is average to good - BUT - the fitted THERMOSTAT was INACCURATE.
Because I set the max temperature at a fairly low reading to avoid excessive scaling (50C) and the water had been warmed by a top-up heater. I did not, at first, realise that the heater was not working at all and went to the trouble of checking out the entire length of the supply electrical circuitry. Set at 50C it was actually clicking off at about 25C.
Replacing the supplied (duff) thermostat with the one from the discarded failed heater cured the problem.
