Central Heating radiators.

[john.a.page]

I have a query concerning gas fired central heating radiators.

I recently moved into a new bungalow and need to temporarily remove a radiator to make good the wall plaster and redecorate the room. However I noticed that the radiator does not have a bleed valve, in fact none of my radiators do, and I am concerned that when I come to refit the radiator I will have an air lock with no means of releasing it.

In my previous home, all the radiators had bleed valves so it was a simple operation to remove and replace them, and cure any air resulting lock by releasing it through the bleed valve.

Should I consider replacing one, or all the radiators with new ones fitted with with bleed valves, or would fitting just one somewhere in the system, be sufficient?

is there a plug with a square hole in at the top of the rad ?

No there is no plug at all. They are all 'single skin' radiatiors with the fins on the back, the only inlet and outlet is at the bottom where the valves attach!

Have a look behind the top of the rad and you should find a small bore hole that holds the bleed screw. Try feeling with your finger and you should find it.
I would be very surprised if there is not one
You won't be able to fit one in the system as each rad needs a bleed valve

sometimes there is a plastic cap on if you cant feel a hole try feeling for a bump
