Thermostatic Rad Valves not working correctly

[Nigel Smith]

Hi we have recently had a new Ideal Logic+ boiler installed the plumber has put thermostatic radiator valves in all of the rooms apart from where the thermostat is. The system is fed by micro-bore downstairs and half inch upstairs. The rooms with 2 radiators is where the problem is one radiator is nearly to hot to touch while the other is barley warm I have tried turning the rads down to about three but I can only seem to get one working properly. I have tried turning the hot one off but the other still does not seem to be heating up properly, the rads the single radiator rooms seem to be working fine. I have bled the rads so no airlock anyone have any advice please.

Is the lockshied valve open?

 

[Nigel Smith]

Sorry Craig don't know what the lock shield valve is

Have you contacted said engineer to give a chance to put right?

No had a few problems with him the radiators were all working fine originally I haven't touched the lockshied valves

Did it ever work?
Take the trv head off and check the lock shield is open.
Try closing all other rads.

 

[Riley]

You didn’t touch the lockshields he mightve

Sorry, working fine before or after he touched it or both?

 

[Nigel Smith]

After he fitted new boiler he replaced all the old valves with trv and the system was fine we have turned a few radiators of in rooms we are not using other than that nothing has changed

Most likely the trv pin is stuck. Take the trv head off and try pushing the pin down. It should move with a little resistance but then spring back up. If it doesn't give the valve body a few gentle taps with a hammer. Did he flush your system when installing the boiler?
