This boiler is about 20 years old but has given good service until recently. Hot water is fine but radiators only come on for about an hour then go cold.Timer says CH is on but can only hear the fan running in the boiler and this will continue until CH times out or is turned off manually. If you then reset the CH to come on it will fire up and run, the rads get hot and then are cold again after about an hour.
Had someone in to fix it (recommended by a couple of people). He changed some three way valve and serviced the boiler, said nothing seemed to be worn. Still same problem. He came back and fitted a new fan, that did the trick but he wanted to come back and fit a new pressure switch, which he did. Now we are back to square one again. I am waiting for hime to come back again.
Any ideas?
