HUBBELL ME-40
0.92 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
Checking this listing against the registry: HUBBELL ME-40, an electric tank, uses 2,439 kWh a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 2,439 kWh, a difference of 0 kWh, and ranks 19th lowest of 163 electric tanks.
Energy use per year
2,439 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 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.
Solid line: this model (2,439 kWh). Dashed line: the class median.

The figure of 2,439 kWh was computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for HUBBELL ME-40, with the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity, and the figure was retrieved from the DOE CCD on 2026-09-19. It holds only at that test draw. A household that uses more or less hot water than the test assumes will use a different amount of energy, and this page does not estimate by how much. The method is set out under how the annual cost is calculated.
Among the 163 models registered as an electric tank at the low draw pattern, this model ranks 19th lowest for energy use, which places it in the lowest quarter of its class. Its use is 0 kWh away from the class median of 2,439 kWh. The data supplied here does not show how many models share the median value. The low draw pattern describes a one- or two-person household, so the figure applies to readers in that situation. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 46 gallons. The rated volume is 37 gallons. The figure does not describe a larger household, and no value for another draw pattern is given here. The selector by fuel, space and size covers other options.
The running cost is not stated in the text because it depends on your own utility electricity tariff. To check it by hand, multiply the 2,439 kWh by your rate per kWh, keeping in mind that the figure applies only to the low draw pattern. The cost calculator on your own ZIP does this for you. The page shows the modeled installed-cost range in its own block, with its source and date. It is a modeled range, not a quote, and it is not restated here. To compare ME-40 with another unit in its class, use the same-class replacement search by model number. This page has no data on your household's hot-water use, so the gap between your use and the test draw is unknown.
