I have recently moved into a house where the boiler and radiators are only 1.5yrs old. When the radiators have been on for a short time you can hear 'air' noise., This stops when you increase or decrease the temp on the side of the radiator - is there anything i can do to stop this - its more annoying than anything else!!

try venting all your radiators at the top right or left sides with a vent key. sounds like you have air in the system.
