The fan makes a high pitched whine when it runs that sounds like an electric saw sawing something thick. When it first was hooked up it made a sound like metal shearing—this has now turned into a this whine. It is even noisier outside where the vent is. It has to be turned down so it won’t run at night so we can sleep. It also may be making other high frequency noise because the dog won’t eat his food and drink when in the house and wants to be outside all the time on the opposite of the house relative to the vent. The boiler itself also is noisy when it runs. Lots of vibration—sounds like a jet plane when it runs. The installer says all this noise is normal. However, I would never have bought this boiler if this is just a common feature of the Lochinvar Noble boilers. So help! What can be done if anything? Can it be returned? Are there boilers that are quiet? How can I get action from the installers on this.
Many thanks for advice or information.
