Hi, I am new to this site, Please help!
I have a combi boiler and 7 radiators, one of the upstairs radiator was not heating up at all and the other was only getting luke warm so had the system power flushed out and also had 4 new rads replaced at the same time. Since then the luke warm rad is warming up more than before but the cold rad is not warming up at all.
The pipe leading to the TRV is warm and if I turn the other upstairs rads off then the cold rad warms up but then if I turn the others back on than the cold rad goes cold again. The other rads upstairs are also warm at the top but cold at the bottom.
The 3 rads down stairs which are closes to the boiler are red hot.
Any suggestions on what to do next?
Many thanks.
