    We have a Vaillant Ecotec 415 system boiler, about 11 years old. It has been serviced annually (most recently in Sept 2021) and we've had a couple of issues with odd noises in the past (once just after servicing), but these have been resolved by a heating engineer tweaking something or other -...

    Had a few guys to look at it already and they say it could be the gas valve but asked me to contact Biasi (who in the end refused to help).

    Knocking sound coming from PVR. Have an in-line pressure tank set at 3.5bar, but downstream a 3 bar PVR. The PVR seems to knock at random times for hours and hours, which is driving me crazy. Is the inline pressure tank pressure set to high?

    Cause of intermittent noise from pump and zone valves

    Open vented fully pumped oil fired system. Works well but occasionally (every few days or do) loud throbbing noise from pipes directly above boiler. Goes away if system switched off and then immediately on again. New pump and no benefit from replacing zone valves. Any ideas gratefully received
