Don't know if anyone can advise what to do. Have two radiators which will not heat up, the lock shield valves are hot but the rads are cold. The TRVs are bi-directional Danfoss units and have been turned up for max heat. All other rads in the house work ok.
I have also gone through the process of bleeding the rads and shutting off all the other rads in the house to force hot water through them but no luck, they got marginally warm but that was about it, any ideas?
Many thanks in advance
