I have recently drained down a gravity feed central heating system,(up stairs only) and installed a towel rail in the bathroom.
When draining down the system I was unable to open the vents on two of the radiators, when filling the system back up I was not able to bleed the air from the two rads with the faulty air vents, so these two rads are not getting hot only warm at the very bottom of the rads.
Any suggestions on how to sort this problem out would be of great help.
Have considered of really trying to force the vents open but didn't want to break the bleed nipple if I can help it.
Many thanks!
