HUBBELL MP45F
0.92 UEF DOE CCD · 2026-09-19Grade G: 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 this listing: the HUBBELL MP45F, an electric tank, uses 3,531 kWh a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 3,531 kWh, a difference of 0 kWh among 426 models.
Energy use per year
3,531 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site did not read the annual figure from the registry. It computed 3,531 kWh from that UEF and the DOE test's daily hot-water draw for the medium draw pattern, using data from DOE CCD retrieved 2026-09-19. Against the 426 models registered as an electric tank at this draw pattern, the class median is 3,531 kWh, so the difference is 0 kWh. The unit ranks 213th lowest energy use of 426, which places it in the second-lowest quarter of its class. The steps behind the calculation are set out in how the annual cost is calculated.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons, and the rated volume is 44 gallons. Those two values describe capacity, and they do not change the energy figure of 3,531 kWh. The medium draw pattern represents a typical household with a busy morning as its heaviest use. If your household draws more hot water than that test, your own use will differ from 3,531 kWh, and this page has no measured data on by how much. A model at the class median of 3,531 kWh suits a reader who wants an average result for this class, not a lower one. To compare sizes and fuels, use the water heater selector.
The running cost is not stated here because it depends on your own utility electricity rate. Multiply 3,531 kWh by your price per kWh to get the yearly electricity cost at the test's draw. The cost calculator does this from your ZIP. Models below 3,531 kWh in the same class would cost less to run at the same rate, and models above it would cost more. To see those alternatives, find a same-class replacement by model number starting from MP45F. The modeled installed-cost range appears in its own block on this page with its source and date. It is not repeated in this text, and it is not a quote.
