I've a pressurised CH system with a combination vented cylinder.
I live in a two story house with 4 radiators upstairs and 4 downstairs. I recently had the CH pressurised and the cylinder also was replaced.
The problems is that the radiators upstairs are getting nice hot but the ones downstairs are not. The pump is working as I can hear it. I bled the radiators and left the lockshiled of the radiators upstairs a quarter closed and the TRVs are at 3. The lockshields for the radiators downstairs are fully open and the TRVs are at maximum. The boiler is Worcester 18ri and is downstairs.
Any advise on what I can try to troubleshoot the problem will be greatly appreciated.
