How much noise does the Rheem hybrid water heater make?

Rheem publishes its decibel ratings at less than 50 decibels. However, in our tests, we’ve seen this vary from home to home. The differences could be because of the acoustics of where the water heater is installed.

In our limited testing, we’ve experienced up to 63 decibels with the heat pump using the Decibel X:dB Sound Level Meter on an iPhone.  If you are concerned with the noise that the heat pump makes when in operation, we highly encourage that you run your own tests. Check various appliances and/or different white noise levels to have an idea about noise levels.
