Coming up to the second winter with this intermittent droning vibration noise from our Vaillant ecotec plus 438 boiler. Besides this noise it works fine and heats everything up nicely.
It doesn't happen all the time and anytime I call a plumber it never happens! Whenever I have seen this it has always been while the temperature is rising and just before the flame shuts off. But again it doesn't happen every time.
The frequency of this tends to increase as the hot water demand has been largely satisfied. And the noise only lasts a few seconds as per the video.
I finally managed to get a video of it happening. Hopefully now someone can tell me what is going on here? For the longest time it sounded like a motorbike was passing outside the house.
Watch the video and turn up the sound.
