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
Its seem to be working It's seems to be working. I hope everything is good with it. Thanks April 23, 2014
Great refresh rate I have only had this water heater for two weeks, so at this point I can only say that so far I am pleased. The best part is the refresh rate. It only fires up for a short time to get the temp back up to full setting. April 21, 2014

Price/value I was looking for a water heater to replace my 25 year old one and i went to Lowes site I checked all the brands available there and read the reviews and definitely this one was the best. Good price, good product, I like the 6 years warranty... and so far is working wonderful. I'm waiting for my next energy bill to see how energy save this unit is. By the way the contractor said that the installation was a piece of cake April 19, 2014
Great features Easy to install.Has all the features needed for a family home. Love the way it looks and fits in cellar. April 14, 2014
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
