It has made a big difference in how we use hot water in our home. I have had the tank installed not quite a month, can't tell how much it is saving on my water and gas bill, but I have hot water quicker. The hot water lasts longer as well. October 15, 2014
Water Heater - does it's job This water heater has been working well and we've had no issues so far. October 5, 2014
Excellent Product, Easy to Install, Automatic everything! Made in the USA, this product makes me proud to be American! The Unit looks sharp, is built solid, installed easily (but don't forget to get Dielectric nipples to connect from the top), and then I set a Temp and the machine took it from there. We were showering within 30 minutes! Lowes and Whirlpool quality rescued our Family on Day 5 of no Hot water! Had purchased a "Rheem" Platinum 12 year from Home Depot, after a pro install at the moment of truth, 5 blinks - called support, defective unit they will schedule a Tech and mail a replacement part that week!? Home Depot swapped that out with a New Rheem unit just built, but after I drained, uninstalled, returned, installed the new unit - got 1/2 a Tank, stopped working. Defective also and would need to be fixed. Returned that junk, went to Lowes! October 4, 2014
As advertised No fuss installation by a first-time gas water heater installation. October 2, 2014
This water heater is excellent This is my first Whirlpool water heater, and I am very satisfied. Materials, workmanship and features are outstanding. October 2, 2014
This product failed to heat water 20 hours after installation I still don't have any hot water September 20, 2014
this unit has great features Have had unit for a short time and thus far I am satisfied. September 18, 2014
Easy enough to install Didn't think I'd be able to install myself, but the biggest challenge was the connectors that are separate from what is provided with the tank. We were surprised to find it had 3 legs, and packaging doesn't reference them. We just installed it today (9-14-14) SO All will be a test. It's been powered up and there are no leaks of any kind at this moment. I'm a novice at plumbing. Thank goodness for the shark-bite fittings. Can't solder to save my life. My only fear is the location of the electric supply being so close to the gas line connector. No odors, but I guess they tested this to make sure it's safe enough. September 14, 2014
Quick hook up removed the old 40 gal and had this in place and filled in about 1.5 hours. September 3, 2014
