This product is great! This water heater was very reasonably priced.I saved $200.00 compared to other brands. It is a nice design and was easy to install. I have always had great success with Whirlpool appliances. They make quality products. I recommend this water heater. October 19, 2014
great feature easy to install very good product and good manufacturing warranty. October 17, 2014
Honeywell gas valve I previously had a whirlpool water heater with the flame lock gas valve and had nothing but trouble with it the whole 3 yrs it was installed. I was at Lowes actually to get parts for the old one and still didn't solve the problem, which ended up being the gas valve/thermostat. Both brand new in the box gas valves and complete burner assembly still didn't work. I went back to look at the water heaters and noticed they had changed to honeywell valves, so I thought I would give them another chance and purchased one. The install went smooth and it fired up like it should...... It's only been in for 1 day, but I'm being optomisic and hoping to have better luck out of this one!! Most of my other major appliances are whirlpool and I've had them for many years with no issues. I think they have worked the kinks out in this water heater, at least I hope so!! October 17, 2014
2 days in...so far so good Fairly easy install for myself and a friend. Took about 4 hours total. Heats well. October 14, 2014
simple easy to install,just unhook old and put new in.but you might have to shorten or make longer hookups.mine went right in. October 14, 2014
Easy installation This product was extreme easy to install and light the pilot with the ignitor switch. The settings are easy to read and select. The capacity (40 gal.) in combination with rating (40,000 BTU) was well above similar models by other manufacturers. October 5, 2014
nice product nice product, easy to follow instructions and installation i would recomment to others ... September 30, 2014
Blinky light Water heater installed easily. I like the blinking led to let you know if there are any issues. I wish it came with some standard installation items such as inlet/outlet connectors. September 29, 2014
Very easy to install Fit almost perfectly where the old water heater was, instructions were clear and very helpful. September 28, 2014
able to buy a 5 year extended warranty & made in the USA Our old water heater was manuf. in the same city and state as this one and it lasted eighteen years. We liked that it was made in the USA as our last one. Again we took out the extended warranty. September 26, 2014
