40 Gallon Natural Gas Water Heater - N40T121-403 4.6 5 153 153
Hottest water so far! Wow! What a difference in the amount of hot water! Out unit is set only at hot and it cranks out more hot water than our 16 year old heater ever did! I did not rate the quality yet is it was just installed, but it seems like a well built unit. Like the darker color gray vs the white color. My friend just bought a 50 gallon 6year Whirlpool hot water heater, but I decided to go for the 40 gallon but with a 12 year warranty for the piece of mind, especially with the new sensors up front. We'll see if it lasts that long! July 14, 2011
This is a great looking tank that is seen everyday in the garage. New today. Plumber had no problem with installation except he had go back to the store for more parts as the parts list did not include the nipples on the top of the tank. Tank started right up a hot water was flowing soon after. August 8, 2014
replacement for leaking whirlpool 9yr. waranty model i was just at nine years when the whirlpool hot water heater started leaking. i was just a week out of warranty and needed to buy a new one. this one has a 12 year warranty vs. 9yr. like the one it replaced. it seems the heating control problem has been corrected on this new one. the old one caused alot of problems even after a factory replacement of burner. i am hoping this one will be free of this problem. since i only had it a few days only time will tell.

Economical price ............... It's great looking economical water heater and was very easy to install......... July 13, 2014
This product has the features I was seeking. This water heater replaced an existing unit. Its measurements and hookup locations had to match up with my existing heater, and I was looking for a longer warranty (12 year) due to its location in an attic. It meets ALL requirements, and was a cinch to install due to a thorough instruction manual. The electric pilot lighter is a feature very much appreciated. June 14, 2014
LOOKS AND WORKS GREAT EXCELLENT PRODUCT THAT APPEARS TO WORK VERY WELL SO FAR. June 9, 2014
INSTALLATION HINTS IT WOULD BE VERY HELPFUL IF THERE WAS AN EXTERNAL DETAIL LIST OF CONNECTIONS NEEDED TO INSTALL. I HAD TO MAKE 3 EXTRA TRIPS TO THE STORE TO GET THE RIGHT HOSE CONNECTIONS. WITH THE RECESSED FITTINGS IN THE TANK AND NO WARNING THAT YOU COULDN'T GET A WRENCH ON THE FITTINGS TO TIGHTEN REQUIRED SPECIAL FLEX HOSES OR EXTRA NIPPLES AND SLEEVES, AND THE GAS FITTING REQUIRED 2 TRIPS TO GET THE RIGHT PART. PART OF THE PROBLEM WAS NO ONE AVAILABLE IN THE STORE TO ASSIST, WHEREAS IF A LIST HAD BEEN AVAILABLE WOULDN'T HAVE NEEDED THEM. THIS WAS AN EMERGENCY LATE EVENING REPLACEMENT. May 15, 2014

Replacement under warranty I called customer service and described my problem. The whole process to replace an older tank still under warranty was started about 3 PM today and was completed and operational by 7:30. All of this occurred on a Friday evening. I had a great installer whop handled the whole process and did a great job with an excellent product May 2, 2014
