Can I install a bleed valve in my heated towel rail?

[Norfolk Ray]

My bathroom has been refitted with a brand new designer type towel rail. This is the highest radiator on my circuit and is slowly collecting some air. My old bathroom rad had a standard bleed valve which was easy to use. This towel rail has no valve, just a "bolt" and fibre washer. To release the air, the bolt can be slightly slackened allowing air to slowly make its way past the threads of the bolt.

But its a tedious process and I fear the bolt dropping out altogether if I undo it too far.

Any suggestions?

Http://www.toolstation.com/shop/p97439 toolstation do an aladdin auto air vent which may fit.

Isn't there a self drilling self tapping vent on the market? Or did I dream it?

If I dreamt it I hereby officially claim it as my patent and this post is my proof and all the money from it is mine you hear? MINE!

if you are spending a lot of time venting you could shut the valves remove the vent screw entirely and vent into a container by opening the valve slightly

It depends on the size of the thread. You can get various size air vents.

If you spend a lot of time venting its probably a symptom of a problem in the system you should address instead.

I spend hardly any time - probably two bleeds a year - but the current arrangement is awkward. Sounds as if the Aladin autovent micro would meet my needs.

Incidentally, where is the air most likely to be coming into the system.

1, not enough inhibitor in the system and what you have is not air but hydrogen from corrosion

OR

2, incorrect configuration causing overpumping and aeration of the system.

OR

3, Towel rail on fresh hot water not heating circuit and corroding, releasing hydrogen
