Cold Radiator

[pidgeon1]

One of our radiators is not getting hot.

The water to the TVR is hot but only travels just passed valve.

I have bled the rad no air from bleed valve.

Rest of bungalow radiators are fine.

Any ideas what I should try next,

Thanks

You could check that the TRV is operating, by removing the TRV head and check that the operating pin on the valve itself isn't stuck down. A gentle tug with some pliers may be required.

It the TRV is OK, whilst the head is still off, and the heating is running I would try turning all of the other radiators to allow the cold one to receive the full force of the pump. that sometimes clears any small blockages or airlocks. Once it heats up then return the others back to how they were.

Has this only just happened? Is the other valve (lockshield) open?

Thanks. Turned off all rads, left bathroom and cold bedroom open and this has cleared blockage either air or grud
