I have a Vaillant Combi Boiler and have only used the heating this winter a couple of times. Yesterday the heating stopped working although I do have hot water.
It used to make quite a bit of noise when I put the heating on but now you can hear the water heating the same as it does for the hot water but no other noise!
Help, I would like to have some idea of what the problem is before I spend a fortune on a plumber!
