Having a problem with my new Greenstar 28i junior and rads fitted a week ago i know nothing about them and its driving me and my wife up the wall. The problem is its make a loud noise when the heating is on, when i mean loud i mean loud i have to run the hot tap and it stops right away, the hotter the heating becomes the more often the noise starts. I have tried slow the cold water supply but that didn't do a thing any help would be great
