Good product I'm very happy with it. I'm one of those people who take scalding hot showers. I never seem to run out hot water. Even with 2 people take a shower @ the same time. The only complaint I have is the pilot light is a little hard to see through the window. I'm on the short side & thought I had a good view by sitting on the floor to light it for the first time. I was getting worried that I got a defective water heater after the 3rd attempt of lighting it and no flame. When I bent lower (why I don't know) and low & behold there was the flame. For all I know, it was there after the first attempt at lighting it. June 4, 2015
Its quite! Husband installed the unit and we are very happy, very quite when running. We had experienced a lot of turbo noise with two other units it was not whirlpool. Very happy with this unit! Very surprised how fast the hot water is hot. May 7, 2014
Just the right sizing for its location, and nice features Installation was straight forward. Slight leaking on top, but after further tightening of the hot and cold connectors all is very well. March 15, 2014
Well-designed product This water heater was easy to install and is equally easy to operate. The control panel and ignitor are very accessible as they are mounted on the front of the unit. It is compact in size and offers several options for the water temperature. I'm very pleased. December 8, 2013
Excellent value Easy to install. Had a few issues lighting. Didn't realize lights didn't light until pilot light was lit. I was waiting for the flashing light.... Once lit, everything worked perfectly. Had hot water very quickly. October 30, 2013

This water heater is great! This water heater works great! Before we got it, our old water heater never had enough hot water for everyone to shower. This one is awesome! No one has to worry about a cold shower! May 15, 2013

Great service. I purchased a water heater with a 6 year warranty approximately 4-4-1/2 years ago and it started leaking. When I called your customer service I was given an authorization number and was able to return it to place of original purchase with no problem. Your warranty is great and hopefully the new heater will last a long long time. November 5, 2012
