easy to install easy to set temperature and easy to install no more taking front covers off at elements September 14, 2014
Feature seem good. It is hard to tell the value and quality of this hot water heater after just one day. The features seem good and we always liked Whirlpool products. September 13, 2014
Water heater looks good. A review at this point just had it a week would be very inconclusive. September 9, 2014
Product appears to be well built. With a just a few days in operation, hot water is plentiful, kilowatt usage has dropped, unit looks good. Per installer, was easy to install. September 9, 2014
electrical connections and drain are not well designed Good unit, except that trying to get 12 guage wires into the small space to connections is close to impossible. Why would you put the drain at the same level as where it is required to fit into a emergency collection pan? Most local code ( rightfully so) require these to be installed with a metal pan so at failure water can be directed out. Even with the 2" oversized pan there is no way to use the drain inside the pan. September 8, 2014
i like the features The great energy saver and read out and was easy to install !!! September 7, 2014
easy to adjust with good energy saving features I had trouble with the electronics in my last Whirlpool water heater but replaced it with another one anyway. In general I've been happy with the quality of Whirlpool products, although the last water heater drove me nuts for a while; sometimes the shower was hot, sometimes not. Bad situation for a person that enjoys a good (reliable) hot shower. The salesmen at Lowes assured me the electronics have been updated and greatly improved in these new models and even put me on the phone with a factory rep to drive the point home. It's easy to set the desired temp and has nifty features and a 12 yr. warranty. It's hard know if it will stand the test of time. September 6, 2014
easy to do very easy to install with my wife and works great. love the smart grid tech. September 1, 2014
Great water heater easy to install First water heater that I have self installed. Great features like the vacation mode. We have never ran out of hot water in our 4br/2.5 bath. We did before with our old water heater. We will change it out of energy smart mode to standard when we have family visit for the holidays. I did notice that there is an orifice in the inlet and outlet of the water heater. We saw a very small drop in water pressure, but this has helped extend the amount of time the hot water heater can run so we haven't ran out of hot water. August 25, 2014
So far so good Filled quickly and came up to temperature quickly. August 24, 2014
