The first unit did not respond/operate @ all....almost purchased another brand but then decided the features this unit has it deserved another chance! SO FAR GREAT UNIT BUT TIME WILL TELL!!!??

very good product purchase experience vas very good no hassles, salesperson was very helpful. Installation was extremely professional and quick. December 8, 2014
Straight forward to install, easy start-up. no issue I liked how easy it was to start up after the install. My only complaint so far was that the drain valve is a bit odd and its operation in not covered in the user guide. Also, there is no adjustment noted for the air mix on the burner. September 19, 2014
Great product...affordable and easy to use Great basic water heater with an added bonus of self generating electronic controls. It was easy to install and started up 24 seconds after that. March 26, 2014
savings Energy savings . I could not believe how much money was being wasted by my old water heater March 7, 2014
Noisy This unit is much noisier than our previous unit. We installed it in the garage and you can hear when it kicks on throughout the house. February 22, 2014
I like the light when pilot is on and ready. It was easy installation and didn't take very much time to get it up and running. The old one went bad on new years day and had to do without hot water. Went to Lowes the next day and bought the new whirlpool. January 13, 2014
This product has a good name. This is the first Whirlpool water heater that I have ever had. I bought the heater because of the name Whirlpool and the price. We will see if this unit can live up to the name it has. September 3, 2013
easy to install and operate My only corncern about ignitor flame was turn off by itself during the winter time. I figured out that I turn the thermostat a little bit higher and working fine so far. January 12, 2013
the lowest price for the greatest energy savings bought at Lowes 621.00 plumber installed 165.00 mid american energy rebate of 100.00 total price paid 686.00 most AO Smith regular .59 energy factor water heaters installed would be very close in price The energy factor of .67 EF is excellent!!
