I have a Baxi condensing combi boiler which was installed about 14 months ago. Over the last few months it has developed a loud whining noise that can be heard throughout the house when I run a bath. It only seems to do it when the water has been running for a while...it doesn't seem to do it when the water is just run for a few minutes. Baxi of course are no help...they simply try to sell me an engineer visit for £225.
Could it be something to do with water flow? It isn't a hammering sound - which I think is sometimes associated with limescale problems. It shouldn't be limescale as I live in only a medium hardness area, the system had a 'flush' on installation and there is a Sentinel protector on the boiler and a Hydroflow limescale preventer on the cold water inlet to the house.
