No Matches Required This water heater is easy to light and maintain. No problems after almost a year. September 21, 2014
Good product so far Just installed yesterday. So far so good. Unit is very quite, not as other negative complaints. Maybe Whirlpool hear enough and correct their design. Light up pilot is ready right on the first time even though the instruction states that it may have to take several trial. Hopefully it will last about 12 years as its warranty. My previous unit last only 7 years (not Whirlpool) The only complaint is ventilation plug is so close to the tank and not straight. It made the hard time for plumber to install the copper tube in.

Love the new Water Heater!! We had a Bosch tankless water heater and I HATED it. It cost so much money over the 8 years we had it, We had to replace it once and pay again for the expensive install. We had to have it flushed out twice a year at $150 a pop. Had to have a filter before it and replace those twice a year at $74 each time. NEVER AGAIN will I buy a tankless water heater. Beside, I live in earthquake country, if the big one hits, with a tank we have some water to use if the water supply goes out. OH, and that story they tell that it will pay for itself over time.....NO WAY, our gas bill did NOT go down and our water bill went up, because you have to have a certain amount of water flowing through the tankless to get it to start heating the water. So, we couldn't use low flow shower heads, etc. August 16, 2014
Like the look of the product To new to know how well it will operate, but so far so good! August 16, 2014
Easy to install and energy saver, self-cleaning. This products has great features, space and energy saver. The most important is self-cleaning. August 13, 2014
Only one little issue... The main issue is that the installed angle of the pressure relief valve creates an interference with the outer body when trying to install the copper piping. This is because the base for the pressure relief valve is canted slightly in toward the water heater outer shell. This may have been caused by rough handling and weak protective measures in the purchase packaging (evidenced by the small dent near the bottom of the outer shell). August 12, 2014
Water Heater has an issue maintaining "seamless" hot water I purchased my Whirlpool 12 Yr, 50 Gal, tall water heater for our 12 year old home, replacing the original water heater that was installed when the home was built. The old water heater started leaking from the tank bottom. We bought the Whirlpool unit from the local home improvement store and had it installed by the store's contracted plumber. All went well with delivery and installation. The Whirlpool product works great with one major issue ...when person A is running hot water (shower, kitchen, etc.) in the house and person B begins using hot water in another location in the house, person A will experience a loss of hot water (goes cold quick) for about 5-10 seconds before heating back up. I have had all the connections rechecked by a different plumber than the plumber who installed the unit and all appears to be connected correctly. I'm surprised this happens as all of our other Whirlpool appliances have worked years w/o issues. July 26, 2014
cool burner lighting technique My original 50 gallon whirlpool water heater only lasted 6 years (harsh Las Vegas water I suppose) but the 12 year warranty was sure worth the peace of mind and the call center arranged a replacement for it with just a few questions. July 16, 2014
