I have an issue with my immersion heater I was hoping the group might
be able to help me with. I am on Economy 7 and since the clocks went
back, the immersion heater is not heating the water up to it's normal
temperature. I am not sure if it is a problem with the heating element
or the timer on the heater, I have had a look at the thermostat and it
is set to 50.
Have you got any ideas about to fix it please?
