Large living room- radiator not heating it

    Bought a house last summer which has a large living room (25ft x 12ft or so). There is just 1 radiator in it, a single about 7ft long. It's slow enough to heat up and cools down very quickly. It gets very hot at the top but is luke warm at the bottom.
    Basically it's not anywhere near heating the room. We're sat every night with hoodies on and an oil rad plugged in!

    So before I ring a plumber, any advice?
    Will a simple transfer to a more modern high output double rad solve our problems? I'm not planning on getting a 2nd rad in as that'd involve drilling/digging and I don't need that right now

    I'm not a plumber, but did you bleed the rad? Also if not used in a few months the circulating pump can seize up.
    Tbh sounds like one, if not both of the above

    You need to approach the problem methodically. One step is to turn off all other radiators. See does it help. Also with this rad only open, bleed it.
    If this does not solve it, a plumber will need to check the flow to the rad.

    The rad is undersized, probably but that's a different issue. Unless there is enough flow, there is no use in putting in a double rad.

    I've bled all the rads in the house. 2 upstairs require bleeding every so often to keep them roasting..let the air out.
    The rad in question in the living room I've tried to bleed but water comes out straight away so air is not the issue there.

    I've adjusted the balancing on all rads. All rads in the house including some news ones we had put in during extension works this Autumn heat up fully. As I said above, the living room rad heats up also after a bit but is not able to heat the room to any real extent.

    Thats what I'm afraid of. Going to the expense of putting in an expensive double rad and still not having a warm room because of flow issues etc

    Can you clarify does the rad heat up fully or not because they are two completely different problems.

    If you need to bleed some rads regularly it would indicate there is a leak somewhere in the heating system. I leak in the heating system results in fresh water being regularly introduced into the system which in turn will cause corrosion and sludge build up, this could be one possible cause of the rad not heating properly

    as john said turn off all the other rads and see what difference it makes to the living room rad, then matbe we can offer more relevant advice
