40 Gallon Natural Gas Water Heater - ND40T62-403 4.2 5 19 19
This product had the energy efficiency and features I was looking for. I am very pleased with the performance. Initially, I wasn't sure if the 40g capacity would be enough but it has great recovery and energy efficiency. With the HE Flue Damper and electronic ignition, I no longer have to worry about the pilot light going out too. February 13, 2014
Great Features would recommend this product works very well with the auto dampner and the auto ingnition. cant wait to see how much my monthly bill will go down. February 8, 2014
Broke Twice in Two Years The pilot light went out after two days and required parts and labor which were covered by Whirlpool. Two years and days later it broke again, but this time I had to pay shipping($30) and labor ($100). They offered free 5-10 day shipping, but what family can go that long without water? I would advise against purchasing this product. February 4, 2014
Great Design and Easy installation! I was dreading the replacement of my old water heater. This unit installed very easily and I love the energy star design, Great concept!!! October 28, 2013
Damper quit working after 2 years Had this unit for two years and it stopped working. Called Whirlpool support. Read them the flashing code. They had me try a few things and determined the damper unit needed replacement. Good news-parts have 6 yr warranty (but not labor). They sent the part at no cost but made me pay for shipping. ($30 some dollars if you need it fast, approx $10 if you can wait 5-7 days without hot water) Luckily this unit was only for one of our bathrooms so we could shower in another bathroom with hot water supplied by our 30 year old hot water heater. Don't think this one will last 30 years. Part was not difficult to install and Whirlpool told me I could do it myself, so I did and it works so far. Will it need to be replaced in 2 years??

pretty ok it worked awesome for the first couple years but recently every now and then it only wants to produce warm water. not sure why. but it was easy to install and very affordable. September 18, 2013
The jury is still out i expect this unit to reduce my monthly gas unit due to it not having a pilot light burning all the time. It is too soon to tell if it is having an impact on my usage and how much of an impact. I do not understand why the 50 gallon version of this unit has a 12 year warranty but the 40 gallon unit only has a 6 year warranty. For $10 more (Lowe's) I could have purchased the larger unit with double the warranty. What is wrong with this picture? July 10, 2013
Good value for the money I compared prices and value and found this one a good value for high efficiency water heaters. May 29, 2013
NICE FEATURES EXCELLENT PRODUCT. EASY INSTALL.LOOKS AND WORKS GREAT May 7, 2013
PRODUCT HAS GREAT FEATURES Unit was easy to install, but I have some concerns about the temp. control. After about one years use the output temp. started to raise and I had to set it from hot to half way to low to keep temp. at 120 degrees. February 15, 2013
