Outstanding Value Our old hot water heater was on its last legs and I was afraid of it failing. It was not a Whirlpool and it came with the house when I bought the house. I went to the store and bought a 40G natural gas water heater with a 6 year warranty on it from Whirlpool. I stand by Whirlpool products 100%. Upon bringing it home and getting ready to set it up I discovered that not only did Whirlpool include a user's manual they included a sort of "quick start" guide to cover the basics in full color. Outstanding! The install was so easy it was unbelievable. Attach the nipples and the new flexible water lines. Connect the exhaust and then the gas line. Fill the tank. Bleed the air from the line via the kitchen sink and then light the pilot. It was so easy that even a caveman could do it! Whirlpool had outstanding directions, hints, and things to look out for in the manual. Even the directions for lighting the pilot and adjusting the temps on the new 6th Sense controls was spot on. I love the peace of mind I now have from my new Whirlpool hot water heater. November 26, 2011
The product is a great value The price of the product was actually cheaper than the online price. The product was easy to install and user friendly. This was a replacement product and it aligned fairly well to my system not too much of an adjustment. The product catches your eye as you enter my laundry room. Great price and energy efficient.

new design I like that the diameter of heater is smaller than comparable 40 gallon ones. April 11, 2014
This product has great features Old unit went out. Did not want to tackle this project with replacing a new one. Called a handy man, he told me what fittings to buy. It looked so easy I did it my self. There was no soldering and extra tools to buy. The jib was really easy. If I can do it anyone can. Thanks BigBil April 9, 2014

water heater nat gas the water heater was fairly easy to install but since i am a retired plumber, the folks at lowes are helpful but for a avg guy they do not give enough information on the different installation kits that are out there easy install an i like the new pilot an gas valve set up, i am 75 so i can not just man handle a water heater like i used to lol April 4, 2014
Has all the hot water and reliability anyone wants. My old water heater was a tankless " on demand type that promoted efficiency. The major element missing was reliable hot water. It varied with the weather & at times took an inordinate amount of time to deliver a steady flow of hot water. The Whirlpool water heater does deliver the hot water quickly & in a steady flow. I finally have the reliability back in the tank which makes for a happy family. April 3, 2014
Nothing has really changed Same old, same old. Removed old water heater, all connections basically lined up with the new water heater. If I hadn't decided to cut out some old corroding pipes installation would have taken just a few hours. March 30, 2014
