This product does have good features. This product is replacing an 80 gallon heater and so far I can't tell any difference in recovery for hot water when I am washing clothes, dishes and taking a shower--all at the same time. May 16, 2015
This product is easy to install. The only problem was the pressure relief valve was turned past vertical by several degrees, making it necessary to add extra fittings to get it lined up to the drain. I figured taking it out and redoing it would void the warranty, It makes for a sloppy looking installation though. May 13, 2015
easy to install and easy to read the operational funsions I have used whirlpool products all my life and will continue to do so because of the reliability. May 8, 2015
Excited Just had it installed. Glad I upgraded to the Smart Sense unit. I am looking forward to the benefits it will provide. Excellent temp and recovery. May 5, 2015
Overall I am very pleased. Product has energy saving features. The heater has been in operation for just over three years. I am currently having a problem with the Energy Smart Module (EMS) and I can't make changes to the available settings. For instance I can't switch from "Smart" mode to "Standard" or "Vacation" modes. I contacted the company parts department and they are sending me a replacement EMS. The water heater works just fine and produces plenty of hot water without the EMS, but I like having the option of changing the settings to save on energy costs. April 29, 2015
I like the ease of setting the temperature Ordered from Lowes, arrived undamaged, made in USA. April 29, 2015
this product has good features like the vacation mode and the digital display to see water temp and adjust April 28, 2015
I was successful at installing a water heater by myself for the first time. The installation video gave me confidence that I could do the install myself. The instructions that were enclosed re-affirmed that. The help-line steered me in the right direction. April 20, 2015
Excellent Value Water heater is only 9 days old, so this is a preliminary review. It has excellent features and a longer warranty for only a few dollars more than the lesser 40 gal. model. It is Smart Grid compatible, so when OG+E adopts that function, I'll save more money under Time Of Use electricity billing currently in place at my home. This unit is quiet, digitally controlled and simple to use. We will see how it works over time as months unfold. April 8, 2015
Feature I like the fact that I can control the temperature with ease as to not have to worry about burning the grandkids. April 3, 2015
