Sorry u r right, it is a Hydra boiler.
Had it fitted over a year ago now.
The plumber who fitted it has been several times
to have a look but can't seem to find the problem
or he does'nt have a clue and yes he is a registered. :?
I have a Vokera Hydro boiler which keeps making a loud humming noise that\\\'s sending me crazy. It makes the noise about every 5 mins then stops When i turn the hot water tap on. Please help before i end up in ward 10. :cry:
