Easy to install Easy to install & fast start up. Had hot water in 45 minuets. August 27, 2014
This product seems to have nice quality. I was real worried when my old water heater gave out in my new home. After replacing it with a Whirlpool to my surprise I felt real good about the replacement. I also purchased an extended warranty with it so hopefully I will not have to replace it for a long time. Installation went real well also. August 22, 2014
This product has great features This product has great features and easy to install. August 18, 2014
Control Unit is easy to understand and operate I have installed 2 of these units............the second was mine and very easy to install and operate. My friend that I installed the first one, is very satified with it and has had it for almost a year. August 13, 2014
Easy replacement, great value The installation was easy and I like the safety feature of a status light on the new style gas control valve. Recovery time is excellent and I'd recommend this model and company to anyone. This was a warranty replacement for a leaking Whirlpool hot water heater installed in 2006. As with a previous reviewer, I too was expecting a hard time, but couldn't have been any happier with the claims process. August 12, 2014
good so far Have only had installed for 4 days but very easy to operate. The do it yourself installation went smoothly. Good directions August 10, 2014

Well designed. This water heater is well designed and easy to install. I was impressed with the features as well as the 9-year warranty. July 13, 2014
Easy to install excellent warranty support I had a 12 year warranty on my old Whirlpool 50 gallon water heater. After 10 1/2 years of constant use it started leaking from the bottom of the tank. I called the warranty phone number expecting to have a hard time connecting to a real person. As it turned out within five rings there was someone on the line. Within five minutes I was given a Authorization number and told to return the old heater to the store I bought it from for a replacement. When I received my replacement heater the store did not have the 12 year model so I was able to take a nine year warranty model and I received a 1 1/2 year credit from my old heaters warranty towards my new heater. I could not have been more pleased with the service. July 12, 2014
