Hi All,
I've re-attached two radiators back to the system after some decorating and I now have the problem where I get heating upstairs but very little heating downstairs to none on some. Followed various tips such as balancing (all rads (4 in total) upstairs are only set to 1/4 turn open on lockshield) and then downstairs are set as 1/4, 1/2, 3/4, 1 turn as I think they are distance wise from the boiler. I have fully drained the system twice and during the second drain replaced the pump on the boiler (WorcesterBosch Greenstar 241 Junior) thinking that the pump was failing.
All rads are bled so I do not think there are any airlocks in the rads so could the problem be in the main pipework supplying the downstairs rads??? Or could there be a blockage somewhere. System was powerflushed ~7 years ago when all rads replaced. All water coming from rads is clear and inhibitor has been used throughout the duration I have looked after the system.
Any help is appreciated.
