we've moved house in the last month. we have ofch which was heating the water until about a week ago when it just stopped heating the water altogether.
Any ideas why or what to do?
Radiators working fine.
house is about 9 years old so tank wouldn't be that old.
wouldn't be too well up on DIY myself.
just don't understand how it was working one minute and the next it's just completely stopped.
Does the tank look similar to that one? If so then locate the input/output pipes for the coil as in the diagram and see if they are heating at all. If not and the reason is not simply the sort of valve/cock mentioned above then you may simply need to get a plumber to look at the system.
When the plumber calls the first thing he will look for is an air lock at the primary coil through you copper cylinder.
There may be a little automatic air vent there and your plumber will open the tiny cap on same and let air out of it.
There maybe a manual vent that he will open with a rad vent key
