EEMAX SPEX65
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).
If you are checking the EEMAX SPEX65, an electric tankless unit, this is its yearly use. It uses 615 kWh at the very small draw pattern, the standard daily hot-water usage DOE tests against. The class median is 615 kWh, a difference of 0 kWh; it ranks 77th lowest of 271.
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 is electricity use. This site computed it, not the registry. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.96. The second input is the DOE test's daily hot-water draw for this draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. Actual use in a home depends on how much hot water is drawn, and the registry does not give that figure. The method for calculating annual cost explains the steps for anyone who wants to reproduce the number.
The registry lists a maximum flow rate in gallons per minute of 0.7. A very small draw pattern means small units, such as a single bathroom or a point-of-use heater under a sink. This energy figure describes that use only. The figure is for the very small pattern, so it says nothing about a unit serving several fixtures at once. A reader with a larger load can use the water heater selector to filter by fuel, space and size. This page does not say which unit a household should choose; it only reports the registry figures.
The running cost is not written here because it depends on your own utility electricity rate. The cost calculator applies the tariff for your ZIP code to 615 kWh. The model ranks 77th lowest of 271, which is in the second-lowest quarter of its class for energy use. Its difference from the class median is 0 kWh, so its use at this draw pattern equals the median. A model with a lower rank number would show a smaller yearly figure on the same calculator. To compare within the class, find a same-class replacement by model number. The installed price range appears in its own block on this page, with its source and date.
