radiators warm only at the edges....

    Lads

    Turned the heating on recently and the heat up fine... but only around the edges of the rads, the rest of the rads are freezing, a bit stange but true.

    Its on all the rads in the house, I turned them all off, and turned thermostat up full and turned boiler on and then turned on one rad at a time hoping to push the heat around, but nothing...

    Someone suggested that I might need to get the rads flushed, but with the house only being 8 years old I thought this might not be the problem, and at €400 to get it done I would rather try a few suggestions first...


    ... anyone got any ideas at all?

    thanks paddy

    Hi Paddy

    There could be air trapped in the radiators.
    Turn off the central heating. Then using a radiatir bleed key( if you have not got one, you can get one in a hardware store) open the air vent at one end of the top of the radiator. Air should start to hiss out.
    When water appears, close the vent. Hold a rag under the vent to catch the water escaping from it. Turn the heasting on again.

    I should have said, this was the first thing i tried no air at all, water started coming out straight away.

    cheers Paddy

    exactly as posted - this isn't strange at all! Airpockets need to be bled.

    Have you checked that the circulating pump is working?

    I have asked a plumber friend about this question.

    He says it could be one of two things;

    As you have suggested there could be silt in the radiators and this could happen after 8 Years.

    Or your circulating pump may not working properly.:(
