Cold Radiators after Powerflush
Posted by Brendan MacNeill on February 03, 2004 at 18:09:13:
After a recent powerflush I've been left with 4 radiators not working. 2 (in basement level) are only heating at the top of the radiator and 2 (middle of house) are stone cold. Could the power flush have been incomplete? Or might it be an air lock?
Any suggestions on how I could diagnose the situation?
