After the heating had not been used for a few months, finally turned it on a couple weeks back. One of the rads makes a gargling / water whooshing sound when the heating is switched on, turned off or when someone turns on a hot water tap (diverting from heating to hot water taps).
tried bleeding the rad and waiting about 30 secs of water coming out but still the same.
It’s a combi boiler and the rad in question is a top floor vertical radiator.
Boiler was fitted a year ago and system was flushed.
Any idea what could be causing this and how to fix?
