0.96 UEF DOE CCD · 2026-09-19Grade E: where this UEF sits among the 271 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tankless unit, very small draw pattern (small units - a single bathroom, or a point-of-use heater under a sink).
You are verifying the EEMAX AM010277T, an electric tankless unit. It uses 615 kWh a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 615 kWh, a difference of 0 kWh, among 271 models.
Energy use per year
615 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is equal to the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 77 of 271, lowest energy first.
Solid line: this model (615 kWh). Dashed line: the class median.

The annual figure of 615 kWh was computed by this site, not by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.96 for this model. That value is applied to the daily hot-water draw the DOE test assigns to the very small draw pattern. The figure therefore holds only at that draw and says nothing about a household that uses more or less hot water each day. The fuel is electricity, and the source is the DOE CCD, retrieved 2026-09-19. The steps behind the calculation are set out in how the annual cost is calculated.
Against its class, the EEMAX AM010277T ranks 77th lowest in energy use of 271 models, which places it in the second-lowest quarter. Its 615 kWh matches the class median of 615 kWh, so the difference is 0 kWh. The figure suits the small uses the draw pattern describes: a single bathroom, or a point-of-use heater under a sink. The registry lists its maximum flow rate in gallons per minute as 1. A household that needs hot water at several fixtures at once falls outside the very small draw pattern, and this figure does not describe it. The water heater selector filters by fuel, space and size.
The running cost is not stated here, because it depends on your own utility electricity tariff. Multiply the 615 kWh by your rate per kilowatt-hour, or enter your ZIP in the cost calculator to get the figure for your location. No cost is estimated in this text. The modeled installed-cost range appears in its own block on this page with its source and date, and it is not repeated here. If you are checking a swap, find a same-class replacement by model number and compare its energy use with 615 kWh at the same very small draw pattern. Metered use in a real home is not available in the data and may differ.
