    Guys, have got 2 rads out of 10 that for some reason are not heating up. The pipes to the TRV,s are hot but the hot water doesnt seem to be passing through.

    Is it possible the TRV's have both gone at the same time. Rads have been bled...
    Any ideas.

    have you taken the head off and had a look if the pins on them have stuck, martin

    Thanks for the reply Martin, I havent removed the TRV yet as I didnt want to interfere unless I knew what I was looking for. I'll remove tomorrow and check the pins. Is it likely the hot water will come through when I remove the TRV and if it does, does that prove the valve is faulty.

    when the head is off GENTLY pull the pins up, if they stick down then the rads stay off - for goodness sake don't yank hard on the pins - some come right out :)
