Great buy on a great heater. I spent a lot of time researching water heaters and found this heater has some of the best features in it price range. I really liked the touch screen to change the settings on the heater and the look of it. It just looks well made and has very good fit and finish. The LCD display was slightly difficult to use at first as I wasn't holding the unlock button down long enough. After figuring that out, it is a breeze to use. The only thing I dislike about the heater is the use of a plastic drain valve. I would have really liked to seen a brass drain valve on this unit and would have even paid a few more dollars for this heater to have that. I would have given a 5 out of 5 on features, value, and quality if it would have had a brass drain valve. April 22, 2014
Liked the cost to features comparison. The unit was very easy to install. Even though I was going from a 40 to a 50 gallon heater, it fit right in and did not require any changes to my plumbing. The instructions were easy to follow. the set-up was easy. Making temperature adjustments is simple and easy. April 22, 2014
Great LED settings for ease of set up. Just installed. Have not had it long enough to see if a difference in water heater bill. Love the rounder circumference and lower height. LED panel has ease of visibility and set up. Like the "vacation" or "long weekend" energy saver mode April 22, 2014
easy to install and does an excellent job Very good and efficent. Was easy to install and set into operation. April 22, 2014
Got what I paid for....I think? Spent a little extra $$ for the 12 year warranty. I'm anxious to see if the 'energy smart' setting truly pays off, or if it's just a fancy LCD screen. Otherwise, it's a water heater. They're all about the same. I live in Johnson City, where American Water Heater makes 3/4 of the ones sold around the US, and all the folks I talk to say a water heater is a water heater, so you basically pay for the warranty. Time will tell!! April 21, 2014
Good value Purchased do to the high user feedback on value and features. It was just installed so I cannot comment on energy efficiency. April 21, 2014
adequate so far It heats enough for one long shower at 120 degrees and low water flow. I expected at least two normal showers. I turned the heater up to 125 degrees and it seems to help. I haven't contacted the installer yet. April 18, 2014
This product has amazing features I f this water heater lasts as long as our last Whirlpool water heater, (10 yrs.), I will be very happy. April 17, 2014
best design/features on the market ! too soon to rate efficiency/overall quality however, I've checked out many water heaters over my 45+ yrs. of home ownership and find this one to be superior to any other brand (in the same category), on the market. might consider a water resistant seal around the inlet/outlet openings on top of tank Great Job Whirlpool - Thank You !

High Quality American-Made Water Heater This Whirlpool water heater is very well constructed with very useful features. Its learning one's behavior as related to hot water usage is very beneficial. Its one touch button to go to vacation mode is great. The ease in setting water temperature is fantastic. April 15, 2014
