Radiator in living room stopped working!

    Hi, wondering if one of you might be able to help me. Radiator in box room wasn't really heating up fully, so bled it today and all was fine, then noticed the one in the living room just stopped working, himself didn't have time to look at it since he was headin to work so I tried to bleed it, water came out very consitantly-prob about two mug fulls, and a very light hiss (hard to hear) the pipe into the rad did get warm but it didn't go any further than that.
    I checked all the others and they are all ok, the one in the down stairs toilet is piping hot the bottom 3 or so inches and is making a serious gurgling sound
    - so maybe the problem is there?? It's gas heating and the house is less than a year old!
    Thanks a mill

    It looks like your system is seriously out of balance and the rad in the bathroom is filled with air. If out of balance is the problem then it is probable that the rad in the box room, having been bled, is taking too much of the hot water and robbing the other rads. Balancing the system is simple enough but it takes time and patience.

    What I suggest you do is:

    Check the setting on the circulating pump -- the screw on the top with markings 1,2 and 3. It may be that it is set to flow rate 1 and needs to be set to 2 or 3 to feed all of the rads.

    Then open all of the flow valves on the rads fully open (the ones with the cap you can turn to turn the rads on). Then pull the caps off the return valves (the ones with smaller caps that don't turn). Close all of those valves in to about one turn open (on many valves you can pull off the cap of a flow valve and use it to open or close the return valve -- or use a pair of pliers to turn them).

    When you have done that with the heating on, check which rads are heating up properly -- those nearest to the boiler will be the ones to check first. You should then find that rads further away from the boiler will not be heating fully. Now you need to progressively open the return valves on them until each one heats up properly -- again starting with the rads nearest to the boiler and working towards those furthest away.

    The idea is to get just sufficient flow of water to each rad to let it heat up but not so much that it takes the hot water away from others. That generally means that the rads nearest to the boiler have their return valves opened less than those furthest away.
