WHEN BLEEDING RADIATORS,DO I BLEED ONE OR ALL OF THEM.
MY COMBI HEATING SYSTEM IS ONLY TWO YEARS OLD,BUT IT HAS STARTED TO MAKE A LOUD NOISE WHEN THE TAPS ARE SWITCHED ON,IT ALSO COMES ON AT NIGHT,WHEN IT IS SWITCHED OFF.
bleed the radiators whilst the system is cold. Start off by doing the lowest rads first and finishing off with the highest rad in the house ie the loft. check pressure gauge then re pressurise if necessary.
