In response to Re: Cold Radiators after Powerflush
: 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?

I have never heard the term "powerflush" used.
It appears that there is air trapped in the system preventing proper circulation. Shut the power to the circulator(s), bleed the air from each radiator and/or purge the air from the system. Make sure all radiator shut off/balancing valves are opened fully.
Good Luck. e-plumber
