Air in Rads

[jonnydon'tknowmuch]

Dear all,
I have had 2 rads repalced, 1 is a tall colum type the other is a towel rail. The problem is every coups of days, they need bleeding as the tops of the rads go cold and fill with air. Anybody have any ideas?

Could be hydogen gas due to corrosion. Did you use inhibiton when you refilled system after doing the work.

it might settle down after a few days.

I'm with Mr Bloggs.

i read it as just had 2 rads done... i suppose it depends on how long that means !

of course u could be right

I am not to sure about the inhibitor, would it work if I added to the system now, and how could I check if it was hydrogen?

bleed some out and have a flame ready. it will light !

when did u have the rads put in

 

[jonnydon'tknowmuch]

About Sept I think

ah......

could be corrosion as stated.

u could treat it to a cleanse/de-sludge and some inhibitor
