Hi, i have recently installed a new central heating system which consists of 6 rads and a vaillant ecotec pro 24 combi boiler. All seemed to be working ok for a week until a loud vibration sound was heard from the boiler. It seems to happen intermittently after the heating has been on for a couple of hours. I assumed that the vibration occurs when the TRVs are closing, so i adjusted the automatic bypass valve. I also adjusted the lockkshield valves on the rads but the vibration is still happening. I have called vaillant helpdesk and they said it could be dirt in the system. I have flushed system through but no joy. Any ideas thanks?

Hi, im sure the installer did flush it thoroughly. He is out of the country at the moment (luckily for him) so i was looking for a solution. When the vibration occurs if i open a couple of trvs it cures it for some time. All the trvs are bi directional. Do you still think t is sludge? Thanks for your reply.
