Hi
Per some of my other threads, I have an issue with a BG 330+ Heat Only conventional boiler.
I've managed to get into the diagnostic menu and double checked Flow & Return Temps.
Despite the Flow Temp being set at 75C, it NEVER gets above c.53C even after 4 to 5 hours of the boiler firing away at full pelt. Return Temp is about 7C lower than Flow Temp.
It is 9 years old and to be honest, only serviced once in that time. What put me off servicing again was the fact that the guy took the front cover off, had a look inside, sniffed and charged me £120....
Anyway, a plumber who I now trust, says that the Flow Temp should try to get as close to the Flow Setting as possible and more than likely the heat exchanger is blocked and f***ed. As mentioned in another thread, it's fed from the Header tank with softened water, despite being an alloy heat exchanger (thanks BG!).
Pro Plumbers on here, would you come to the same conclusion that I need a new boiler?
Thanks in advance!
John
