This unit has great appearan and ease of operation After reading many reviews I liked the idea of the energy smart feature that remembers usage. The contractor that installed found it very easy and also liked the features. I am hoping for some savings on energy bills but will have to see after a couple of months. Reviews indicated that some people had issues with flow restrictions but I have experienced no problems. August 20, 2014
great features The water heater was very ease to install. The contractor had it installed and operating in less than an hour. August 20, 2014
This product was easy to install and works great I found this product to be very easy to install. I didn't run into any difficulty and the instructions provided were very clear. There were also diagrams on how to properly wire the product. Also the instructions were very helpful with the operation of this heater. This particular model has a digital display with options to allow for energy saving opportunities. This is especially useful for vacations. This model will likely pay for itself just based on efficiency. I have always enjoyed Whirlpool products and this water heater is no exception. Thanks to the research and development team and all who helped to make a fine product. August 13, 2014
this product has great features. The instructions for installation were very precise and above average for many items I have installed. Very user friendly. I like the touchpad for adjustments such as energy savings and vacation mode. August 12, 2014

easy to use easy to install and use just had to buy different hookups August 7, 2014
Excellent Product Installed easy, no leaks. I had warm water within a half hour and the entire tank was 120 degrees by an hour and fifteen minutes. I can't wait to try out the energy saving features. It is very quiet and looks great. Great price too. July 26, 2014
Great unit for the price Great unit for the price. Purchased from Lowes. Instructions for installation were very easy to follow and saved me from having to hire a plumber to install. July 25, 2014
You Asked The heater was dented, packaging didn't protect unit from damage. The drain valve is a plastic one, I'll replace before installing it. In general it's OK but after-all it's not a space shuttle it's just a big tube with two heaters inside and all the hoopla in the world won't change that. Is it as good or better then the one it's replacing, time will tell but the one in service now is fifteen years old and still works, I believe in being proactive so we shall see if this pans out.

Great Features I love the features this unit has on it. Good appearance and should lowers energy bill. July 5, 2014
