A bought a property recently with an immersion heater. The water was scolding. I tried to vary the thermostatic setting, but the temperature was always too hot to touch.
I visited the local plumbing shop who recommended that I change the thermostat. After changing the device, the temperature was still too high (factory setting was 65). I turned down the thermostat and immediately the temperature went down. However, this time is was just a tad too cool for my liking. So I turned up the thermostat a fraction. I went out for a couple of hours and when I got back there was the smell of burning. I sourced it to the immersion which I switched off. I took the immersion cap off and saw the inside was black and so were the wires although they have not burnt out.
Does anyone have any idea what has happened?
