This unit is ideal for our busy lifestyle I really like the display that shows the water temperature settings. I also like the ability to program the unit when away from home or on vacation. January 13, 2015
The product was easy to install and works great for our small family. I self installed the water heater in the attic. I had pre-wired for the install. It was easy to hook-up. Once I turned power on - it ran itself. It has worked great since. I recommend this to water heater to those do-it-yourselfer's. Thanks Whirlpool!!!!!! January 4, 2015
This product has great features We haven't had this product very long but so far it is working fine. December 20, 2014
The design was 2 inches smaller and made the istallation better I have all Whirlpool products in our home and have confidence that it will continue. Thank you December 17, 2014
well insulated and great feature of tempature control choices so far all very good except location of drain valve; believe it to be to low which will make draining difficult because it is below lip of drain pan. installation instruction could be improved say on one page smart grid technology vague November 25, 2014
Love the whirlpool water heaters This is my second whirlpool heater from lowes,the parent company located out of Tn was nothing but helpful with 2 warranty issues on my last water heater during it's 10 year lifespan.They immediatly shipped me a new part that was simple to change out on top of the water heater.I love the energy efficient features and have sold several friends on what a great product you make. This one heated up the first tank of water in 12 minutes. I highly recommend these heaters, go ahead and but the 9year model,you won't be sorry. November 14, 2014
easy to install water heater was easy to install and needed to read instructions to program. I have installed several water heaters and this was one of the easiest to install. Haven't used it long enough to tell how it performs or how it is with energy savings. November 13, 2014
The "SMART" Features are ideal for our lifestyle We have owned many Whirlpool products as well as several Whirlpool hot water heaters. The appliance performance is very reliable. When and if service is needed there is no hassle. Whirlpools Tech Service is very good. Will keep on buying Whirlpool products. November 11, 2014
Just Purchased, great price for the product Limited expertise on plumbing; other than changing some 30 year old fittings from the house to the water heater, the install was easy. I like the digital display and programmable features. Reviews were good for the product so expecting to have the unit for many years. November 9, 2014
The features are easy to use I like the fact that this is an Energy Saver Hot Water Heater and with easy to use buttons for when I go on vacation. I am impressed by how it is streamlined and fits perfectly in the spot allocated. It's not too big or to small and gives me hot water when I need it. November 7, 2014
