Hi all,
I had my new boiler and 13 radiators installed in July last year, but since installed all the radiators always top half hot and bottom half cold or warm. I know that if radiators top half hot bottom half cold/warm, it indicates there's sludge in the system. But as the radiators were all new, so there should be blockage in the pipes/heating system?
By the way, I had one engineer checked the boiler filter, it was full of sludge around it, the engineer suggested because it was newly installed probably it was not flushed the system, and I did NOT see the installer power flush the system when installed boiler and radiators at all.
So now, to power flush the system will sort out the radiators top half hot&bottom half warm/cold issue? The house pipes are very old, although radiators are new, I am afraid the leak would happen. Actually, after the boiler/unvented cylinder installed, there were two leaks happened, one is upstairs bathroom basin tap burst out, the other one is kitchen underground pipe burst.
Thanks for all advice!
