Good water heater This water heater is fine. Made in the USA. I'm not super stoked about not having a battery backup on the unit so that if the power fails, I have to reset it. Installation was a breeze. The T and P valve leaks a little bit after a long reheat. I figured that it would stop leaking after a week or two, but it's been about 5 weeks of very light leaking. Not a big deal, just strange. Good unit overall. November 22, 2014
I like automatic pilot This natural gas heater was a perfect replacement for the 15 year all unit it replaced. This its the first time I replace a water heater and was Easy to install. after checking all the items in the check list provided in the manual, turn the unit on and it work like a charm. Very happy with this unit and its working very smooth. November 19, 2014

OK so far What can you say about a water heater - it heats water! It was on sale at Lowe's when my old one bit the dust - no problem with installation and everything is fine so far. Of course it has only been 4 days, so we will see! November 11, 2014
This is a good product. This is a good product. However, the product stops working properly by leaking at the time we are notified it could break down. that makes me feel like it is made to break down at that time so another sale is required. That makes me feel like product is set up to break down at that time so the Whirlpool can guarantee themselves another sale based on sales of past. November 5, 2014
Ease of use Installed myself, was a little larger than the unit i took out but planning everything out made it easy. So far 3months in, have noticed lower gas usage, kicks on as it needs to witch is awsome, no constant pilot wasting gas. November 2, 2014
Good replacement unit Good replacement unit when our previous unit lasted just over the bare minimum warranty. October 26, 2014
This product heats quickly and not that noisy. The reviews I read before I purchased the product said that it was noisy within 12 feet. I almost did not purchase this model because of that. It turns out that the noise level is about the same as the previous continuous pilot light one. I especially like the ignition pilot light. I had a full tank of hot water within ninety minutes of installation. October 19, 2014
nice appearance this water heater is very clean looking and very quit.Easy to read instructions .Great warranty.produced hot water very quicly.Great electronics on water heater. October 15, 2014
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
