Hello,

Please can someone take pity on me? I have a radiator in the onsuite with valves etc. that look like these.

The radiator is cold at the top and hot at the bottom - so how do I get the air out? There's nowhere to put a radiator key.

Has the flat head screw (pic 3) replaced the radiator key nut in old school radiators?

Cheers.

That last picture 3 is showing the bleed screw(facing towards the wall) and use whatever it takes to loosen the screw and it should bleed the rad.
Don't use pliers. Use a small spanner. There are keys to fit that screw and should have been supplied with the rad. If you have a sealed system then don't forget to refill.

A standard bleed key will fit over the nipple (where the little slit is) on the last picture.
