I had a combi boiler installed a couple of years ago and have been having some trouble with it ever since.
My spare bedrooom radiator wont come on at all - have had it on low for a year as don't use that room but the other week turned the thermastat to on and it did heat up for that night but now wont heat up at all. I've tried taking the thermastat off completely but still nothing.
The rest of my radiators - if I turn the thermastats down on some of my radiators they go completely cold.
Last year I had to bleed them all the time but this year no air has been trapped. Any advice would be greatly received. Thanks x
