I was dreading the replacement of my old water heater. This unit installed very easily and I love the energy star design, Great concept!!!

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??

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.

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?

Good value for the money
I compared prices and value and found this one a good value for high efficiency water heaters.

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.

I am well pleased with everything my new water heater has to offer, from the quietness, the auto-electronic starter/stopper, and expecially the internal insulation feature. No more outside wrapping. It speaks of quality over-all.
Thanks Whirlpool for everything.

new 40 gallon 6th sense water heater
Very efficient, and heats up very quickly. I had an old gas water heater (installed 1994), and it served me well. It would take a good bit of time to recoup after being drained of hot water. The new Whirlpool heats up in probably 1/3 the time it would take my old water heater to recoup. I've only had it 9 days, and it has been good so far.

PRODUCT WORKS GREAT
THE UNIT IS QUIET EXCEPT WHEN HEATING THE TANK OCCURS BUT THIS IS NOT VERY LOUD AND MY UNIT IS IN THE GARAGE. I DON'T EVEN KNOW ITS CYCLING AND THE IDEA OF THE SELF MONITORING LIGHT SYSTEM IS A GOOD ONE. WOULD LIKE TO SEE A BATTERY BACKUP FOR THE ELECTRIC THERMOSTAT. LOSING POWER WOULD MEAN NO HOT WATER UNLESS YOU HAVE A GENERATOR TO PLUG INTO.
