I had a Bradford white power vented water heater put in a few months ago. It seems that the power fan is making a noise throughout the house. When I stand right next to the heater the fan sounds fine. But it makes this whirling noise through the house. I do not want my plumber thinking I am a nut case. It is somewhat annoying. Should those blowers be silent?
Anyone know how warranties work? I paid him to install the heater, he supplied the heater.
Yes they can be noisy. Check and make sure that nothing is obstructing the vent. No screens. bugs, critters, etc. Just a suggestion.
Explain to him whats going on and have him come out and make sure everything is working correctly. It's possible it could have went bad. Not likely though. At only 3 months old, I'm sure it's still under warranty if needed.
