I have a conventional set up with a Baxi Solo and hot water tank (vented system)
When the boiler starts up (hot water only or central heating) there are loud noises coming from the pipes to/from the boiler
I have had lots of problems over the years, last plumber I had was convinced there was a build up inside the boiler but he flushed it out and said it was clear, he couldn't find a blockage/or any air, he spent a good 4 days on the system and couldn't resolve the issue and then would not take my calls, he has left me with an overide on the flow switch in the boiler
I am reluctant to drain the system as whenever I have I have had problems getting the system operational again
I have tried adjusting flow rate on the grundfos pump whcih temporarily helps but the issue returns
I get a small amoutn of air out of the highest radiator every month or so but nothing too much
Appreciate any help
