As i said earlier. Worcester engineer has checked that the boiler is set up correctly. He will not check the rest of the system as thats not their responsibility.Hello guys. Apologies for not replying sooner. Just had a lot of health issues and some other personal problems which took priority over this, so I'm very sorry again.
WB engineer came out. He made some adjustments to the boiler settings telling me that they were incorrect, but this has not made any difference. I have gone around, bleeding the rads, but there is no air and it's made little difference. I don't know what else we can do. Room thermostat is set to 25C, the heating is on for 5 hours and the temperature of the room rises from 18C to 19.7C or 20C at most...this can't be right.

The problem will lie with one or all of the following. system balancing, auto bypass setting,system blockage. My guess would be system balancing. You have said this is correct. But i would be 99% certain that it will be wrong.
Press the OK button for 5 seconds and this puts the boiler in max rate for 10minutes. Do all the rads get piping hot? if they don't then the issue is balancing.
As a very quick setup for balancing. open all trv's to max. then on the lockshield valves ( opposite end to trv's) on each radiator close it fully and then open 1.5turns on all downstairs rads and open 1.0 turns for upstairs rads. Then turn on heating and test
Thanks denso13 for clarifying that. Maybe snb didn't see the post.
Hey snb! Thanks so much!. I have some great news. I followed your suggestion of putting the boiler at max rate. The display changed to a 100% sign and temperature quickly rose to high 80s. Next thing I know is that ALL the radiators then went absolutely boiling hot within less than 10 minutes and could not be touched at all.
I assume now that the rads are piping hot, I can safely eliminate system balancing? But what does this mean? What do I need to do?
