Rheem 65 gallon hybrid water heater
We recently built a new house using a lot of the new technology for air sealing, insulation, etc. One of the items we included was a Rheem 65 gallon hybrid water heater. Before purchasing it, I researched the different brands and discussed it with Rheem directly. Two different people at Rheem stated it had a noise level of 49 decibels comparing to a refrigerator. Our water heater is located in the center of the house next to the two bathrooms and in the same room as the washing machine. I wanted to minimize wasted water down the sink or tub waiting for hot water. I can tell you this is the second Rheem hybrid water heater we have installed in 6 months and they do not run at 49 decibels. Both clock in at 75 decibels and you can hear it from every room in the house and even when you are outside. I am so disappointed. The walls of the utility room are insulated with Rock Wool Sound insulation on all four sides. While this helps slightly, I usually run the water heater in electric mode which does not help on energy savings but at least I can hear the TV and I do not get a headache listening to the heat pump. For all of those considering switching, you may want to consider how loud a hybrid water heater is before laying out almost $2000 for the heater alone. Our water heater is going to be relocated to the garage as soon as I can find the time. That will be an additional 45 feet of pipe to empty out before water gets to the bathroom or I have to put in a separate circulating pump.
