too hot water
 

Hot water, as heated by the central heating is ferociously hot, There is some type of adjustable wired thermostat clipped on to one of the pipes entering the hot water cylinder but fiddling with this has no effect.

Is this a job for a plumber or an electrician ?

Probably a plumber - usually this tends to happen when a three way valve
sticks so that the hot water is always heated whenever the boiler is on.

An electrical thermostat failure more often produces cold "hot" water.

H/W tank stats are usually on the tank itself, if it's on a pipe that
might be a stat for pump run-on ...

Plumber probably, however it should be an easy DIY fix.

If you work out what type of system you have:

you should be able to trace through what is going on...

Are you sure that you haven't left an electric immersion heater on
(assuming both methods available for heating a tank of water)?

The thermostat controlling the hot water in a tank is usually clipped
around the tank to monitor the temperature of the water in the tank. It
makes no sense to have it fitted to the pipes. An inlet pipe would
supply cold water, and outlet pipe would only be hot if the hot water
was being used, the boiler pipes would be supply hot water at maybe a
much higher temperature until the water in the tank reaches a certain
temperature.

Sounds like either the thermostat is u/s or set high or the valve is not
closing when the thermostat signals enough. So the water rises to the
same temperature as that coming from the boiler.

Yes a good clout with an adjustable spanner of suitable weight might sort it
for a while. a friend of mine used to keep on under the kitchen sink for
this purpose!
