Hello everyone. I have the following problem and I have not found a clear answer what to do. Well, the point is that when the stove goes out, at a temperature of about 36 degrees, it starts knocking and jerking the tubes (as if it would break them immediately). I think the sound is coming from the differential valve. I am asking for advice on what to do in this situation. I would like to add that I do not know much about this field 
I am throwing in pictures of the layout in the basement.
