Thermostatic radiator valve - sticking

Just 22 years ago

Hi,

One of my rad stats has stuck shut so have cold radiator. Looking at previous posts on this site, you can unstick it by "pulling up pin with a pair of pliers".

Looking at mine, if you prise the plastic top off the control, there is a chrome knob about 12mm in diameter, which you can depress & it bounces back up. Is this the pin? Not sure of make but says Concerto on control.

Any help appreciated - I'm not competent to drain system & muck about with it, but if there's a quick fix I'd like to know!

The ones we were talking about, you unscrew the thermostat head (like taking off the top of a bottle) by unscrewing the gnurled ring underneath the thermostat head.

This leaves you with a brass pin sticking up out of a right angle bend.

No prising involved - you may have started to prise the thermostatic top apart which was not part of the plan.

I think you're right, the 12mm thing sounds like the wax capsule on an old one I'm looking at.. :-)

Thanks, undid knurled ringnut & removed thermostatic top and there was indeed a pin there! Gave it a pull with pair of pliers and it seems to have done the trick. Justin
