Whine from a boiler pump?
About two years ago we had a natural gas Burnham hot water boiler installed after a major basement flood. This new boiler, when operating, creates a very distinct high pitched whine. When I complained to the installer, they stated the circulating pump they installed, not the boiler, causes the whine. They said there is no reliable way to prevent this whine -- however they did say there are stainless steel and rubber bushings that can be installed where the pump connects to the system to minimize the whine; however, they are not very durable and very expensive and not worth the trouble.
I am still faced with the problem of having a heating system that is warm, yet very loud. I have a hard time believing that a product would be developed, like this pump, where there are not reliable alternatives. In addition to the solution above, are there any other ways to get rid of the whine?
