I've just fitted a new Cylinder Thermostat same as this :

Its been wired up same as previous stat : 1= Yellow 2= White 3= Blue &
Earth

I sparked up the system and left it running for half an hour (usually
long enough for reasonably hot tank of water) I then turned down the
temp. control to see at what point it shut off, It didn't !! I turned
it down to lowest setting 20 deg.C still no joy.

Is it a faulty stat ? or incorrectly wired ?

Why did you replace the original? If it was because of the same 'fault',
it isn't the thermostat. More likely a valve.
