    new radiator fitted remains cold

    hi I have just fitted a new radiator in the bathroom downstairs. All the other radiators are hot except this one. But the pipes to the radiator are hot?

    Have you tried bleeding the radiator, it sounds like it has air trapped in it. Some radiators require a bleed key which is available from all good diy stores.
    IF you are unsure of how to do this then check here http://www.diynot.com/pages/pl/pl033.php or here
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

      If you have bled the rad, then you may have an airlock, try turning all other rads off and run the system with just the new rad open.

      Then turn on all rads, run the system and them bleed them all.

      Should do the trick.

      Cheers, Des.
