HUBBELL ME50HPT

3.46 UEF DOE CCD · 2026-09-19
B

Grade B: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).

If you are checking the HUBBELL ME50HPT against the federal registry, here is its figure. This electric tank uses 939 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,592 kWh below the 3,531 kWh median of the 426 electric tanks registered at the medium draw pattern.


Energy use per year

939 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 below the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 90 of 426, lowest energy first.

This model: 939 kWh

What these figures mean

The 939 kWh figure is not printed in the registry. This site calculated it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 3.46 for this model. The second is the daily hot-water draw that the DOE test sets for the medium draw pattern. The source is the DOE CCD, retrieved 2026-09-19. Among the 426 electric tanks at the medium draw pattern, this model ranks 90th lowest for energy use. The figure holds only at the test's daily draw. A household that uses a different amount of hot water will see a different yearly figure, and that figure is not available here. The page on how the annual energy and cost figures are calculated sets out each step.

The medium draw pattern represents daily hot-water use in a typical household, including a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 58 gallons. Its rated volume is 47 gallons. When checking whether this model fits a home, compare the 58-gallon rating with the household's own busiest hour. A home that needs more hot water than that in its busiest hour is outside what this rating covers. The class comparison covers electric tanks only, so it says nothing about gas or other fuels. To look at other units, use the water heater selector by fuel, space and size. To find a unit in the same class, use the same-class replacement search by model number.

The text on this page gives no running cost. The cost of 939 kWh of electricity depends on your own utility tariff, which is not known here. The running cost calculator for your own ZIP applies your local electricity rate to this model's annual use. The same rate applies to the class median of 3,531 kWh. At any one rate, the running-cost difference follows the energy gap given above. The installed price appears in its own block, dated and with its source. It is a modeled range, not a quote. Real use can differ from the 939 kWh test figure when daily hot-water use differs from the test's draw. The registry does not show how large that difference would be for any one home.
