My heating system has started creaking. It starts as soon as the pump kicks in and then some of the rads and pipes tick as it heats and cools.
Worcester combi boiler and the system is about 7 years old. Have bled the system till I am blue in the face, not a lot of air. Is this just a problem with the pipes running through the joists? Or can I cure it by upping the inhibitor concentration?
