Hot water isn't the first thing you think about when running a business, but it can stop work in its tracks when it fails. For commercial buyers, the challenge is finding an electric water heater that delivers enough stored hot water without turning the utility room into a power-grid project. The AO Smith DSE-120A 200 enters that conversation as a commercial electric water heater.
Quick verdict
If your electrical service can support a 120 A appliance, this AO Smith model is worth putting on the shortlist. At USD 5,850, you're getting a commercial electric storage tank water heater that's new in its crate, with the AO Smith name on the model. It's a straightforward answer for a buyer who already knows they need tank-style electric hot water.
Who it suits
This unit is best suited for facilities that already run electric water heating and have the power capacity to handle a serious amperage draw. It's also a good fit for buyers who prefer a unit that hasn't been used. If your site checks those boxes, this model is designed to keep up with repeated hot-water demand.
What stands out from the listed details
One detail stands out immediately: the amperage is built into the model name, so there's no question about the electrical appetite of this unit. The listing also identifies it as a commercial electric water heater. That combination tells a buyer this is meant for a commercial setting with real hot-water demand, not a generic appliance.
Meaningful trade-offs
The biggest trade-off is the 120 A electrical requirement. That's a heavy load, and if your building's service can't handle it, you'd need to factor that into the project before moving forward. This is the main constraint to weigh.
Bottom line
For a commercial buyer with sufficient electrical capacity, the AO Smith DSE-120A 200 is a clear path to new electric water heating. At USD 5,850, it sits at a commercial price point, but the commercial spec and the AO Smith name make it a strong match for the right facility.
AO Smith DSE-120A 200 Commercial Electric Water Heater (New in Crate)

Named for its amperage, this AO Smith model is a commercial electric storage tank water heater listed as new in crate. A concrete reason to choose it: the storage tank type keeps a supply of hot water ready, and the new-in-crate condition means you're not inheriting someone else's wear. The limitation to weigh: the electrical draw is a fixed requirement, so your service needs to be up to the task.
