Always bleeding one rad

[lordyjordy111]

Hi all

was at a customers today and he said he was always bleeding one rad up stairs....

all the others had water in and sure enough the rad the customer had complained about had air in it?

It was not on the negative side of the pump and had no leaks.

any ideas on what would cause it

not unusual to get one radiator that seems to catch the air going round the system.
what type of system is it?
is it air, or hydrogen being produced?
