Thanks guys, really appreciate your help. Tony, I don't think all plumbers are thick at all , far from it but some would prefer to sell you a new boiler than fix a problem with an existing one. I need to try and fix the boiler if I can rather than fork out cash I don't really have for a new one...
Hi Tony/Ray
Thanks for your info so far but we are still trying to identify the exact problem. We think it might be the 3 way actuator as the readings for open circuit weren't showing correctly, have you come across this and do you think it is likely? I have worked out I can get hot water...
I have been reading some of the posts on here aboutBiasi boilers for some advice. I don't have any hot water at the moment but the central heating is working fine. I had an engineer out who checked the flow and pressure and told me he would suggest I get a new boiler as it would cost too much...
