Cold radiators

[Bagpuss 7272]

Hi there,
I'm new to this forum, so please bear with me.

I have a problem with my central heating.

I recently cleaned, emptied and refilled the system and added the silencer. The system seemed to be working fine. But now I can't seem to get any of the downstairs rads to get very hot. I've checked and there is no air in any of the rads or the pump. The pump and valve seem to be working ok. I've got no problems with the hot water side. Anyone have any ideas??

Have you checked out the available info on balancing the system.....?
Its possible you have an airlock somewhere but balancing is a reasonable start.
