Hi - we have had new radiators fitted about 6 months ago ("DuraTherm Horizontal Double Flat Panel Designer Radiator" from plumbworld - sorry, this site won't allow me to include a link to the site). Every radiator in the house was swapped for one of these apart from an older one in the bathroom, as we plan to renovate that later. Our system is a Baxi combi boiler, just over a year old.
One of these radiators - actually the one in our bedroom makes a loud gurgling sound, which wakes us up. It's not constant, and only seems to start after the radiators have been on for an hour or so. The radiator seems to get warm all over, and bleeding it has not helped.
I did wonder whether there wasn't enough inhibitor in the system, so I added some Fernox, but that hasn't helped.
I don't know what else to do. I'd be surprised if it was sludge since all but one radiator has been replaced, and the water seems clean enough (the MagnaClean filter seems quite clean too).
