Title: Radiators warm upstairs and hotter downstairs
Post by debra68 on Nov 9^th, 2010, 8:15pm

HELP PLEASE
I have had BG out twice on the heating cover and then an independent boiler specialist and it still does not seem sorted. So far the the system has been balanced twice and then I was informed that my system may need flushing. I know the water in all my radiators is very clean. I have a baxi combi 105e which is about 10 or 11 years old at least. After looking on different websites I have found that there may be a problem with the pump. But how will i find out the problem as I cannot afford to just keep trying different things as it is not cheap to keep getting an engeniner out.
I hope that is enough information

Open all the lockshield valves 1/2 a turn at a time and close the hot ones a 1/2 turn at a time then keep tweaking them until all the rads are the same temperature.

Is it possible you have a gravity loop upstairs and only the downstairs is pumped?
