    Rads stay hot

    Thanks for all the advice so far. The boiler was installed last year and worked perfectly until the end of the summer when we wanted the heating on for the first time. First of all we weren't getting any heating. The installer came and flushed out the system and that got the heating back on...

    Have a problem with a Gloworm Ultracom 30 CXi boiler. With all valves on the rads closed and the room stat turned down the rads stay cold - OK so far. If I open a valve the rad stays cold - still OK. If I turn the room stat up the rads with open valves get hot but some of those with closed...

    Glow Worm Ultracom 30 cxi - no heating

    Help - we recently tried the CH for the first time since before summer and although we get DHW the boiler doesn't fire up for CH. Room stat clicks at about 23 degrees - have even tried replacing the stat but made no difference. The internal timer on the boiler is disabled for CH although I...

    Glowworm Ultracom 30CXi central heating doesn't turn on

    WilfredoLimb - I have had the exact same problem with the same model boiler. I've tried replacing the room stat - still the same. Did you get yours resolved?
