:( I HAVE GOT A HUGE PROBLEM WITH MY HEATING SYSTEM. ALL MY DOWNSTAIRS AND ONE OF MY UPSTAIRS HEATING RADIATORS ARE REALLY HOT, BUT TWO OF THEM ARE NOT WORKING AT ALL. i HAVE BLED ALL RADIATORS, BLED THE PUMP, PUT IN A FLUSH THAT I BOUGHT INTO THE TANK, CHECKED ALL VALVES AND THEY ARE WORKING AND STILL THE TWO RADIATORS ARE NOT WORKING. HELP PLEASE.
If the suggested balancing does not work, it is likely that you have an airlock in the pipes to the non working rads. Gradually turn off all except one of the working rads. This will force water thru the non working rads.
I assume you have checked that the lockshield valves are open and that the TRV's, if fitted are working.
