Evening
I have a Vaillant 835 e combi boiler.
All was fine up until a few weeks back and I noticed a knocking noise on the boiler.
I turned down the temperature for the rads and this got rid of the noise.
But now it's getting abit colder I want to turn up the heat but back to the same issue?.
Also the hot water has started playing up not sure if it's related? But starts off hot for about a minute then gradually goes luke warm, if I turn of tap and wait a few seconds and turn it back on the same occurs.
Any help would be gratefully appreciated.
P. S...
Brought the house in February this year and boiler was serviced before purchasing.
