Rheem AM007240T
0.95 UEF DOE CCD · 2026-09-19Grade F: 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).
If you are checking the Rheem AM007240T, it uses 622 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 7 kWh above the class median of 615 kWh among 271 electric tankless models at that draw pattern.
Energy use per year
622 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 above the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 152 of 271, lowest energy first.
Solid line: this model (622 kWh). Dashed line: the class median.

The figure of 622 kWh is computed by this site, not published by the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.95. It applies that to the DOE test's daily hot-water draw for the very small pattern. The source is DOE CCD, retrieved 2026-09-19. Against the class median of 615 kWh, this unit uses 7 kWh more. Its rank is 152nd lowest energy use of 271, which is the second-highest quarter of its class for energy use. The calculation is described on the page about how the annual cost is calculated. The data here does not show how the figure changes under any other draw pattern.
The very small draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. This model's maximum flow rate in gallons per minute is 0.6. That rate is the figure to compare with the fixtures the unit would serve. A household whose hot-water use matches the federal test's daily draw can read 622 kWh as the yearly electricity figure for this unit. A household that draws more hot water will use more than that figure, and the registry data here gives no value for it. To look for alternatives in the same class, use a same-class replacement search by model number, or narrow the options by fuel, space and size with the water heater selector.
The running cost is not stated in the text, because it depends on your own utility electricity rate. Multiply 622 kWh by that rate to get the yearly cost at the federal test's draw. The 7 kWh difference from the class median of 615 kWh scales with the same rate. The cost calculator on your own ZIP does this with the tariff for your area. The modeled installed-cost range appears in its own block on this page, with its source and date, and it is not a quote. Actual use depends on how much hot water your household draws, so measured use can differ from 622 kWh. The registry data does not include measured use in your home.
