What Customers Are Saying

Customers overwhelmingly praise this water heater for reliable performance, effortless installation, and strong value. Most highlight how simple the setup was, with connections matching perfectly and minimal adjustments needed. Reviewers consistently report ample, consistent hot water output, with the 40-gallon capacity and 3800-watt element heating rapidly even in smaller homes. Many replaced units that served over two decades, noting improved performance. Several chose based on brand reputation for durability and longevity. A few mention concerns about the plastic drain valve durability or isolated noise issues, but these are rare exceptions to overwhelmingly positive feedback.

Quality has gone down hill.

At the time I opened the box at home my new hot water heater was dented, and the plumber warned it could be an issue or it could be cosmetic. Having no hot water, I had the plumber install the dented hot water tank. I think I am generous giving you a 3 score.

Here's what happened!

Would Recommend

I was forced to replace my old water heater (an A.O. Smith) by my home insurance provider because it was 16 years old (in great working condition - I had the elements replaced a few years ago). I expect my new one will provide me with just as good service as the last one.

Will it last?

Would Recommend

This unit was installed last week, looks good. Time will tell about how good this heater is. My Rheem unit, the one this one replaced, lasted 19 years. I heard they don't make them like they use to.
