I am think about installing a power vent water heater in my house. I’m concerned about the noise from the vent blower. I’ve considered AO Smith, Bradford-White, Rheem and State. None of their sales literature specify the noise level of the vent blower except for State Industries which claim they have a “quiet modular blower”. Is there any brand that is quieter than the others. Just how noisy are these things? Thank in advance for any advise.
