Question about Water Heaters
Upstairs rads where cold on bottom warm on top. took them off and flushed the out (lots of thck black oily gunk) the boiler is v old (thorn m b71238/4 ) there now appears to be no water pressure to bleed rads so they are still cold. down stairs are working normaly
Have you sorted problem yet? sounds as though the cold feed is blocked or as the other guy mentioned an air lock.You can sometimes turn the pump on & off a couple of times as it can dislodge the air lock & shift it allowing you to fill the rest of the system. failing this you can back fill it using a hose connected to the water main & connect to a drain **** either on one of the rads on the groundfloor or on the boiler, once you have filled the rads disconnect the hose & close off the drain point

You have air lock in top floor rads must bleed it out start with the one closest to boiler and work your way out to what you figure is the end of line as best you can figure
