I have a RavenHeat boiler which is giving me some grief. The central heating doesn't come on when i press the switch to on or auto. The pressure is ok , but it wont strike up. Any help is appreciated. I have looked at the manual and i am inclined to think the control unit has packed up. The light come son but nothing happens. I think this boiler is absolute rubbish and i'm thinking of replacing it. Thanks.
