This product was very easy to install. The water heater looks good and it's nice to get away from the standard white color I've always had. The water heater when ignited was so quiet I didn't know it was on. I will always buy Whirlpool they honor their warranties, tech support and customer service is very good. November 17, 2014
easy installation. Work very good so far. I like and trust to be loyal to Whirpool. My last Water heater was also Whirpool . I like it. This one to replace for the old one, I just want Whirpool. October 20, 2014

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
