Hi!
My Vaillant VCW 242 is working just fine on central heating, quiet as a mouse. When hot water gets drawn off though, it sounds like there is a lot of air gurgling in the boiler. Hot water draws OK! but I am just wondering what might be causing this gurgling noise. The auto air vent seems to work fine, and as I say, there isn't that noise with the heating on.
Am just wondering, could this be caused by diverter valve not functioning 100%???
Cheers!
Phil
