If you’re tired of hot water heaters that promise the world, but offer a lackluster experience at best, then it’s time to make one final upgrade. You deserve an appliance that meets all current regulations, guards against corrosion, and won’t give out on you in a year or two. The AO Smith ENS-50 ProMax Short Electric Water Heater also makes a design adjustment so it can fit in non-standard locations with relative ease.

What Are the Features of the AO Smith ENS-50?

What stands out the most about this electric water heater is the Permaglas coating for the interior of the tank. Instead of letting the water hit the steel seams and begin to corrode almost immediately, like many cheap water heaters tend to do, this AO Smith model protects the tank so you can maximize appliance life.

This water heater offers a first-hour rating of 62 gallons that is spot-on with our own observations. As for recovery, this AO Smith model offers 21 gallons per hour. We found that it took about 2 hours to completely refill this tank with temperature-specific water, which is a little faster than the rating.This coating is further benefitted from a PEX cross-linked polymer that helps to reduce sediment build-up and reduce lime from difficult water sources. Even if your pH is a little off and you’re dealing with tough scale, this design helps to create a better source of hot water. It works with water softeners and filters just as effectively as it works with a direct source.

The brass tamper-resistant drain valve is another feature of note with this model. It’s positioned well on the tank to provide nearly complete drainage for servicing and stands up to a standard home environment quite well. It can even handle an accidental bump or two with relative ease. The shut-off valve is equally easy to access and use.

It comes with a 6-year limited warranty on the tank and the parts. It works with ¾-inch connections.

What Are the Advantages of the AO Smith ENS-50?

The real advantage that homeowners receive by installing this AO Smith water heater is the sacrificial anode. It features CoreGuard technology, which is a stainless-steel core that is surrounded with an aluminum shell. This helps to further protect the tank from corrosion and it lasts much longer than a standard steel sacrificial anode.

It operates off dual 4,500-watt elements, with a maximum wattage of 6,000. Sizing is 24 inches in diameter and 50-inches in height will providing 50 gallons of hot water support. This makes it a viable water heater for homes that have limited spacing. It is approved for installation in cabinets and in many crawl spaces.

When all the features and advantages are combined, this Lowboy offers an energy factor of 0.95. The AO Smith ENS-50 ProMax Short Electric Water Heater provides consistency with options and that is why it earns our recommendation today.
