Viessmann Boilers Guide

Hi Guys,

I have a Viessmann Vitodens 200W boiler. It is about five years old. A few days ago, I heard a tinkling sound coming from my boiler, which lasted for few seconds & then suddenly went away. However, from last two days, the boiler is constantly making some weird sounds just like a creaking noise. What is the matter?

Thanks

Adam

Hello, if you hear some creaking sounds coming from the walls or floor when the heating system is running then, this could indicate issues with the pipes within the walls or under the floorboards. Hot water always expands the pipes while traveling from the boiler through the walls. Once it cools down, pipes will then contract back to the normal size automatically. If the stretched out pipes fit extremely tight to the floor then, you will hear these creaking sounds as they contract & expand. I would advise you to find out the cause of the noise & check water pipes in that particular area for better fit. Moreover, if the water pipes are very tight try to cut a notch in the surface to make extra space for the water pipes to stretch out.
