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
This product is state of the art. I replaced a 12 yr old A.O. Smith water tank that had started to leak, I researched a bunch of water heaters and although all of them have both satisfied and un-satisfied customers the satisfied far more outweighed the other so I went to Lowes and purchased this one. I installed it earlier today and it seems to be working just fine, I did purchase the extended plan as I am 60 years old and a heart patient so I wanted to make sure my wife wouldn't have to worry about labor costs if something happens to me or it. The unit comes with a 12 year parts warranty (awesome) It took me 2 1/2 hrs to install and turn on. Most of that time was getting it down the basement steps and empting the old one out. Glad I bought it and it has a very clean look to it. Thanks Whirlpool April 15, 2014
PRICE AND EASE OF INSTALLING Great control panel and easy to install, great price for the energy savings April 15, 2014
A very well built and thought out product. This unit provided everything we needed for the size of our home. Ease of installation with little to no modifications. After the installation and clean-up the unit was ready to be purged and fired up. The amount of time that it took for the water heater to heat up 50 gallons of water at a temperature of 45 degrees, to set operating temperature was impressive, under an hour. I would Highly recommend this unit to friends and family especially if you have smart grid technology available in your area. April 12, 2014
Piece of Junk Bought it, installed it, DOESN'T work! Can't return it. Must wait at least another day for a replacement part - FOR A BRAND NEW WATER HEATER! - and installation. In the mean time, we can not prepare food, clean, or wash our hands because we have no hot water!!! I would not recommend the product. April 10, 2014
Great fratures and nice looking to boot. Delivery was fast and the installation was straight forward. The real test will be how long the water heater will last. When I called your help number to determine if dielectric couplings were necessary when the heater was connected to copper tubing, your representative responded within a few hours. April 8, 2014
