Hi, I hope someone can shed some light in a strange thing happening with a radiator. When the heating comes on (only just put it on) with the timer, all but one radiator work fine. The one that doesn't heat up is at the bottom of the house (downstairs toilet). I've bled it etc no difference. However, when I set the time to "continuous" mode, with no other changes to anything, hey presto the radiator heats up fine (along with all the others). Scratching my head as to why this us happening. Any help is much appreciated thanks, Harj.
