i have a electric water heater when it was turned on the water automaticly
got hot all the time now when the hot water is drained and the tank fills up
I have to manualy turn it on again to heat up the water its a pain in the
a*** every time the washing machine or dishwasher is on I have to turn the
water on and every morning I just boght a thermostat as I thought it was
that that was at fault had a look at the tank and there is 2 x thermostats
is it likely to be the top or bottom one thats faulty
Thanks for reading
Manually turn *what* on again? The thermostat?
Two thermostats in a tank normally mean two heaters. The bottom heater,
with its associated thermostat, heats the entire tank of water - but
this takes a lot of time and electricity. The top heater, with its
thermostat, just heats the water at the top of the tank, relatively
cheaply and quickly. Normally the bottom heater is powered by off-peak
electricity and is on at night whereas the top heater uses full price
electricity and is only used when the off-peak tankful has been used or
has got too cold.
If by "turn it on", you mean at the controller - it may be that the
switch was originally set to "continuous", so that it heated the whole
tank at any time of day. If it is now on "auto" - you will need to press
the over-ride button to get it to heat a tankful during the day.
However, it won't be the thermostat. If that fails, the water will
either overheat and even boil (very dangerous and has led to fatalities)
or not heat at all, no matter what switches you turn on.
sorry should have explained it a bit better .On the control switch there are
2 buttons one says"on" the other is "cancel"
when I pressed the on button I had hot water all the time and did not need
to press it again I always had hot water now after the hot water is used and
the tank fills up I need to go and press the on button every time water
