Hi, first post to the plumbing section
My vaillant turbomax boiler has started making a juddering moaning noise when the hot water is on. It does not do it with the central heating. Sometimes it is constant, sometimes intermittant. If the water is run very slowly (still triggering the boiler), the noise is reduced to just a bubbling type of sound.
Any ideas what the problem may be ?
Thanks,
Simon.
