I'm not very good with plumbing so any simple answers would be appreciated.
My hot water was working fine until a few days ago, now I'm only getting
about a sink full of hot water before it starts running cold.
The immersion is obviously working as I am getting some hot water but
why would I only get a sink full rather than a tank full?
Thanks for any help
Probably because the element is on its way out, and the bottom part of it
has gone. In the next few days it will probably stop working altogether!
If not you are losing water or heat somewhere, if i were you i would replace
or have replaced, the immersion heater now.
Before replacing the element consider a faultly themostat. Turn the power to
the immersion off and remove the cover on top of the immersion. There should
be a thermostat there. Increase the temperature on the thermostat first. If
that fails to get you hot water then short the thermostat out with some 2.5
cable and then see if your water gets hot.
Many thanks for all your help, I managed to order a new heater from
screwfix 5 minutes before their 6 o'clock cutoff last night and it
arrived at 8 this morning, I've just had a loveley hot bath :))
We had a post here recently with similar problems - they had *two*
immersion heaters and the main one had gone faulty, leaving the little
one at the top still working.
It only heats the very top of the tank, so you wouldn't ever get a full
So, look to see if you have two.
If you do, it could be a fuse, the timeswitch, the isolator switch, the
thermostat, the element or the wiring...It might just have got switched
off, by mistake...
Some immersion heats have two elements. A small one for a sinks worth
of hot water and a big one for a baths worth.
It sound like the big one has gone one circuit & you will need a
plumber (unless you know how too) to replace it.
