Hi,
1970's built 3 bed semi. Baxi boiler and pump working fine.
I had a cold rad in the kitchen (last in the loop) and a cold rad in the master bedroom upstairs (not sure where in the loop). All other rads were working fine.
I drained the kitchen rad and flushed it with clean cold water (there was a fair amount of black sludge). I refitted it and bleed it. I also did the same with the master bedroom rad.
Since turning on the heating again, I get very hot water running up to the TRV on the first rad located halfway up the stairs (The TRV is on the left side). But there is no flow through this rad and All other rads are now cold. I've opened up the valves fully both ends and still no flow. Just hot in the bottom left hand side, cold on the bottom right and slightly warm at the top.
I went around all the rads and bleed them, but there was no air tramped.
I also tried opening up the valves (both ends) on all other rads to see if that helped, but still the same. Just getting very hot water to the first rad halfway up the stairs and all others cold.
Any clues to gettiing the flow going again?
Cheers, Ellya
