Hi
Would really appreciate if someone can help, done the 100 hrs on the web trying to fix myself but need guidance.
I have a two story house with boiler in external garage. I have recently added eTRVs on all but 1 rad, cleaned system etc. Issue is when I have only say three/four rads open the flow is poor through them and goes up and out the vent pipe (path of least resistance I assume) not as bad on pump setting 1 but on 2 it is a full flow out the vent. Pictures below, any way I can stop this, looked at combining the Vent and Feed but not sure where to join and also would have the filling air lock issue associated with this but would rather that problem than the circulation up the vent and down the feed.
Any guidance much appreciated
