Noisy Radiators

Hi! The article says if the flow of water through the boiler is insufficient it can create banging in the boiler. Further, it says it\\\'s important to have correct water-flow rate. But I sometimes have only two (out of seven) of my radiators on, to economise. Does this mean there\\\'s not enough water going through? It does bang! Also, my bathroom (where the header tank is kept) has become incredibly damp. I think this must be due to steam coming out of the header tank (into which I keep hearing water dripping). My bathroom was never this damp until I started economising. Also, I do have corrosion inhibitor in the system, so is there likely to be any damage occurring? Any ideas please? Thanks!

sounds like your boiler is over heating and pumping over into the header tank

Thanks ... any idea why? Is it that I don't have enough radiators on?

try opening them up
could be many problems for pumping over.
but you should leave the rads on a bit stop the room getting damp etc.

Thanks, I did put them on. The problem seemed solved, and the bathroom has dried out! PHew! Nevertheless, I'm not sure why the boiler didn't like having only two on. Because if I'm at home all day and it's very cold, I don't want heating all over all day, but might want one or two. Having said that, I have now turned some off, so only some (more than two) are on, and it still seems okay.

it don't cost any more to have seven on or one.

Does it really not save money if you turn radiators down/off? If so, what is the point of having thermostatic radiator valves? What about zones? Does it not save money if you turn the upstairs circuit off during the day or have that zone stat at a low setting?
