i balanced my rads using the method described on this site, and using an infra red aim and shoot thermometer.
All of the rads now get red hot like i wanted, but i can now hear the water flowing through the rads quite loud, not a humming, just water hiss associated with flow. the pump is on speed 2.
if i open all the LSV by 1 turn the noise quitens down but the downstairs rads start to be colder again. is there anything i can do to make it quiet? or will i have to deal with it if the system is balanced ok?
