heat pump water heater reliability

[Duane Jonlin]

All, I'm finally getting around to electrifying my own house.

There is one popular brand of residential heat pump water heaters that may have been causing problems for homeowners. I won't mention that manufacturer name, but could each of those of you with HPWHs installed please let us know which model you bought, and whether you've had any technical problems with it?

I had a Ruud Ultra Series Professional installed in April 2021 (2.25 years) which is identical (to my understanding) to a Rheem of the same 60 gal capacity.  I have had no problem with my household of 4 people, and been using about $140/yr worth of electricity.

One of the things I did was install a mixing valve set at about 115-120 degrees, which allows me to set the temp on the heater to its full 140 degrees during peak times (a lot of company) to mimic a larger capacity heater while keeping the water temp relatively safe.  It also always me to keep it in "Eco Mode" full time which avoids using the electric heating element, even when maxing out the temperature.

I love it's smart phone app, which allows me to fine tune the heating schedule of the water so I can have it down to it's minimum setting of 110 degrees 80%-90% of the time.
