Choosing a commercial water heater is more than comparing tank sizes; you need to think about your building's power source, how much hot water you use during peak hours, and whether you're comfortable with used or open-box equipment. The four listings here range from $600 to $5,000, giving you a 4400-dollar spread to work with.

Product Notes
CHROMALOX Commercial Water Heater 480 V, never used or installed, brand new
This listing is described as never used or installed, and it stands 78.5 inches high. The Energy Star rating is 5 stars. The main trade-off: the unit is not factory sealed, and the required power source is specific to certain buildings-check the decision matrix. If you have the right power setup and want an Energy Star-rated storage tank that shows no signs of use, this Chromalox sits in the middle of the price range and offers a specific set of features.
RINNAI CHS19980HCXiN DDO 199K BTU 8, H-Series Hybrid commercial water heater
The Rinnai is the only brand-new unit in this lineup. It's also the only one with Wi-Fi capability, and the Uniform Energy Factor is 0.97. The 32-inch item diameter is a spatial consideration. The hybrid design is more complex than a simple tank, so it may require more careful planning. At a near-top listed price, it's a premium pick if you want a new, high-efficiency unit with smart connectivity.
Rheem commercial water heater E50A-9-G-1
This is the least expensive listing in the comparison, making it a low-cost entry into commercial water heating. However, it's also the only used unit, so you're taking on the risk of unknown prior service history. The condition attribute is what separates it from the others, and the price position is the main selling point. If your budget is tight and you're willing to accept a used unit, this Rheem is the most affordable way to get a commercial water heater.
NEW Rheem Triton 199,000 BTU GHE100SU-200 Natural Gas Commercial Water Heater
The Rheem Triton is described as having never had water in it, with a minor ding in the outer cover. That suggests the unit is functionally unused despite the condition label. The main limitation is the high listed price, which sits at the top of the range. The power source and capacity are in the decision matrix for comparison. If you need a large-capacity, high-output system and can accept a small cosmetic hiccup, this Triton is the most substantial offering here.
Final Recommendation
Let the decision matrix be your starting point for matching power source and capacity to your building. Then look at the condition column to see which listing state best fits your tolerance for prior service or cosmetic flaws. The product notes above highlight the unique details of each listing. Your final pick should balance the listed price, the condition, and the size your operation actually needs.
