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.

Great product

My old water heater was 15 years old and started leaking. I’ve been looking for a replacement for almost a week, I looked into many different types and brands. The reviews on AOSmith brands is what made me decide to go with this product. So far all is good, happy to have hot water again.

I love the heater but when I opened the box the heater has dents on it! I don't know if it happened during the delivery. I had no choice but to install it because I didn't have any vehicle to return it to store. I have pictures of the damage as well

Nice looking appliance

Would Recommend

It looks very appropriate tucked into the corner of the laundry room. The plumbing contractor crew who installed it had no problem with the plumbing connections. The electrician who connected the power was in and out in about 5 minutes, making a connection from an existing disconnect with a new whip to accommodate the greater height of this tank than its predecessor being replaced. Within 30 minutes there was fully heated water to the 5 faucets in our small house that are fed hot water. So...
