One radiator in the house (which I believe may be the furthest from the boiler) makes a loud clicking sound. The noise is not just when the heating comes on / goes off. Every few minutes (last timed at 8 and 3 minute intervals - when the pressure is at its uppermost and lowermost in its cycle) the one radiator loudly "clicks" (noise similar to the pipework warming up / expanding). I read recently (a link on this site somewhere) about "balancing radiators". I can see why this might be done and can also see this might be a cause of the noise, but the link does not explain what happens if a rad isn't balanced?? If the water is entering and leaving the radiator at the wrong temperatures (either too hot in or too cold out) then the expand and contract of the radiator would be regular and intermittent and could cause the noise...is this a sound theory?? (I have fitted new valves to all the rads when we moved in last year. All instructions i have seen though do not really talk about balancing...it seems to be a divine right of the locksheild valve that will magically happen!) How would i go about balancing each radiator in turn - i don't know what order they are in and do not have a radiator thermometer? Or, could the rad "just" need a clean?

This is the article I had already read which just tells you how to, not why or what happens if you don't balance the radiators. Would sludge or dirt in the radiator be a cause of the clicking? Not sure whether it is of note that the clicking seems to come from the side of the radiator where the water comes in.
