faulty immersion heater?

Hi all,

Have a problem whereby our hot water pipes have started vibrating and the hot tap downstairs starts dripping when this happens. If we run the hot tap for a while, it stops. The hot water is also extremely hot.

You think our immersion heater could be faulty, causing a build up of pressure?

Have you tried turning the thermostat down on the immersion first?

Thats what I would check.

Where would the thermostat be?

switch off the isolator, take the top off the immersion heater, thermostat is in there.

However it sounds like it has failed. This is a dangerous situation and you must not use the immersion heater until its sorted

Most likely the rod thermostat has failed.
Switch off electric, take top off immersion heater you will a thermostat, red, black or blue usually, it that which has failed, only about £7 to replace.
If your confident with electrics, it's easy to replace , BUT note position of wires, you need to remove to know it's length, they vary from 7", 11", 18"or so.

Temperture should be set at 60 - 65degrees, I usually do 65, but some people set them at 72 degrees.
