Towel Rad Problem

[Spinny]

Towel Rad in the bathroom has not been getting hot or even warm since we started using the heating again.

Have opened the bleed point and no air, so it isn't full of air.

There are two shut off valves in the cupboard underneath but both are turned on.

The rad has a 90Deg hand adjustable chrome twist valve on one end which I have opened fully. (see pic). I cannot see how to further access the internals of this valve e.g. to check for a stuck pin. There is no grub screw, and no ovious way to remove the twist cap ?

The rad has a 90Deg fixed valve on the other end with a screw off cap, but after removing the cap it doesn't have a lockshoeld type piece to turn, so how do I open it please ?

 

See Photos, and mucho thanks for any help.

Did it get warm previously?

 

If you haven't fiddled with it since last time it worked why do you think is suddenly become shut

 

It's more likely your issues are with other rads stealing the heat before the flow gets to this rad - decorated any rooms recently?

I mentioned an issue I have with my downstairs rads to a plumber doing another job in the summer. Despite me saying the system has been rebalanced 3 times he went around yet again adjusting some valves upstairs - so I suspect he has fiddled with the valve.

 

I have already tried turning all the upstairs rads down/off using the thermostatic valves except for the towel rad, and still the towel rail does not get hot.

 

So it would appear to be a lack of flow through the towel rail. Possibly a stuck valve or one the plumber closed down - hence my desire to understand how I can adjust these valves

OK 

 

Allen Key in the centre - anticlockwise to open more clockwise to close would be my guess
