Excellent Installation was very easy. Also, the features were easy to use . Just started using so I have no idea if it will lower my energy bill. June 11, 2015
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
Quality product It's larger than one being replaced This is the first time I've ever purchased a water heater. Whirlpool is a reputable brand and I'm confident this waterheater will give many years of quality service. June 29, 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
Product a good buy for the money Nicely built water heater ..my last one had a 9 year warranty . last 14 years .. and this one is built even better 14+ years will be appreciated ..keeping fingers cross.. June 26, 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
