folks, please help, i'm at the end of my tether, after too many engineer visits to mention........in the morning the combi boiler comes on with the timer, there is brief banging noise from what sounds like the pipework, cold radiators (this does not happen in the evening when the timer comes on) if i then run the hot tap (hot water still ok) then the radiators start heating up as normal
i have had new pumps, pcb's, and a system flush to rule out blockages - this gave us normal service for 2 days before this started to happen again
any ideas?
many thanks
