Bleeding a heated towel rail.

[BrickByBrick]

We have recently moved and have a Worcester towel rail. Currently only the bottom section is getting hot. I can't work out for the life of me how to bleed it though.

At the top is the silver screw, I have felt all round the back etc and cannot feel any other inlet holes.

Any advice would be gratefully received. Thank you.

What happens when you turn the silver screw?

In other words - isn't that what you open to bleed it?!

I can't turn the actual screw bit and I can't seem to turn the nut. It has flummoxed me.

Found a better screwdriver and managed to turn it.

Was there ages as a who lot of air came out and then had to adjust the boiler as the pressure had dropped.

But all sorted and lots of lovely heat coming through.

Thank you
