Hybrid Water Heaters

Heat pump or hybrid water heaters transfer heat from the surrounding air to the water and will produce cool, dry exhaust air. Today’s heat pump water heaters have the ability to run in only heat pump mode for the most energy efficient usage or in conventional electric resistance mode. When operating in heat pump mode, heat pump water heaters do not heat water as quickly as conventional electric resistance water heaters, particularly when recovering after significant usage. Consequently, to maintain performance, heat pump water heaters may switch to a less efficient electric resistance heating mode. These two heating modes are why heat pump water heaters are also referred to as “hybrids”.

Hybrids are optimally designed to be installed in unconditioned or semi-conditioned spaces for example garages or basements. However, if placed in conditioned space, hybrids will produce cool and dry air that is a benefit in the summer months but will lead to higher heating bills in the winter months.

If a hybrid is the right product for you and you need to install the hybrid in a conditioned space such as a laundry room, you have the option of ducting the exhaust air outside.

Rheem publishes their decibel ratings less than 50 decibels, however, in our tests we’ve seen this vary from home to home likely depending on the acoustics of the location the water heater is installed.  In our limited testing we’ve experienced up to 63 decibels when 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 you to run your own tests of various appliances and/or different white noise levels.
