This product has very good improvements over my previous unit. I found it easy to install since it was almost the same size and model that I have just taken out. All the fittings and pipework matched perfectly, which was done by a plumber on my previous unit that I had for 8 years. I really like the flashing light which tells me if everything is running fine OR many lights to show what problem that I may have in the future. This is a bonus for me as it'll be easier to fix. I also like the "green" feature of 2 inches more insulation than my previous unit. June 21, 2015
easy to set up and install. this is my second one they work great. One question, this is a propane water heater, why does it cost 200.00 more than a natural gas one. almost the same parts????? April 9, 2015
Very reliable Had one like this for 9 years with zero problems. Old one had valve stop working. I like the short model made installation easy. New valve control is nice and very visual for checking operation. I wish some more options for energy efficiency were available for us propane users. Work on that! April 5, 2015
It's a water heater. It heats water. I picked it up at the store. It had all of the pieces that I expected it to have. It was simple to install and it works. Ask me again in 10 years. :-) January 28, 2015
long life My last heater lasted 10 years and I expect this unit to do the same. January 20, 2015
So far so good Just installed this less than a month ago seems to function well so far. the last water heater only lasted 6 years, January 12, 2015
Great water heater. Very good product and was easy to install. I will certainly consider Whirlpool for future products. December 12, 2014
Love this product Working excellent and the water heats quickly. Smooth running, not noisy at all. Like the 6th sense feature that warn you of any malfunctions. November 20, 2014
Really impressed with the new water heater. This was a replacement for a 25 year old unit. The old model was a 40 gallon short model and I replaced it with a Whirlpool short model which kept me from having to shorten the water pipes as I would have had to do if I had put in the 10 inch taller unit. I really like the piezo pilot light. Sure beats having to light with a match or a butane lighter used to light a grill. It is eye pleasing to look at and my wife loves it. The only problem I had with my old unit was I had to replace the thermocouple twice. This time the gas control valve went out and I didn't want to put any more money into it because of its age. If I get this good of service from my new Whirlpool water heater I will be delighted. November 7, 2014
We have "Hot Water" Everything works well....we have plenty of hot water..I perhaps should have gotten the extended warrenty from Lowe's. JDee November 4, 2014
