Cold Radiators

jimbur

Hi all

I live in a bungalow with 3 heating loops, I have two radiators that are stone cold, with the heating on I can bleed out 8 or 10 pints and the radiatior will get warm, not hot.
I ave turned off 2 loops to try and give the pump a chance but still no joy.
I am 99% sure its not air, not a whisper when i open the bleed stud.:mad:

I cant make sense of it any ideas???
Thanks

Presume it heated before? Turn off all other rads bar one of two not heating. Also turn off your hot water cylinder by closing the balancing valve or on the clock if you have a zoned system with electric valves

Tried that with no joy, it will actuall push the water up into the expansion tank rather that into that rad.

Make sure both rad valves are open on the rads, you should get the pitching problem sorted as well.

Make sure the motorised valve is opening.

Checked all valves all open, i found the boiler to be to be empty and full of steam, I back filled it and went again, no joy
I will go at it again!
