We've lived in this 3 story largish victorian house with old cast iron radiators for about 8 years. I think the c heating system is about 12 years old. The boiler was replaced 18 months ago.
This evening a rather loud constant noise started from the system. The noise sounds as though it is coming from inside a section of wall on the second floor that has been plasterboarded. Presumably there are pipes running up inside this wall to feed the radiators on the 3rd floor.
I was able to stop the noise by turning off the thermostat on the third floor.
Would it be a reasonable guess that the noise is a second pump that has worn out, and the pump is controlled by the thermostat? If so I'm guessing its hidden inside the stud wall.
Or could it be the motorized valve be making all that noise?
Just thought I'd ask if this is likely before ripping out the wall and finding nothing there!
