LOCHINVAR HETF-55 1**
0.94 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking this unit's energy use: LOCHINVAR HETF-55 1** uses 5,278 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 3,972 kWh above the class median of 1,306 kWh, and 172nd lowest of 194 models.
Energy use per year
5,278 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 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 172 of 194, lowest energy first.
Solid line: this model (5,278 kWh). Dashed line: the class median.

The annual figure of 5,278 kWh was computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.94 for this model, with the DOE test's daily hot-water draw for the high draw pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The comparison group is the 194 models registered as an electric tank at the high draw pattern, and its median is 1,306 kWh. This model sits 3,972 kWh above that median. It ranks 172nd lowest in energy use of 194, which places it in the highest quarter of its class for energy use.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. For that use, the first hour rating, the gallons of hot water available in the first hour from a full tank, is 75 gallons, and the rated volume is 55 gallons. Those are the two capacity figures the registry lists for this model. The energy figure is not a prediction for one home. It applies at the federal test's daily draw, and the registry holds no data on your household's actual use. If low energy use within the class is your priority, a rank of 172nd lowest of 194 is the relevant fact. The water heater selector filters by fuel, space and size, and you can find a same-class replacement by model number.
The running cost is not stated here because it depends on your own utility electricity tariff. To estimate it, multiply 5,278 kWh by your rate per kilowatt-hour; the cost calculator does this from your ZIP. The result applies at the same high draw pattern, so a household that uses more or less hot water than the federal test will see a different figure. The steps behind the calculation are set out in how the annual cost is calculated. Because this model is 3,972 kWh above the class median of 1,306 kWh, your rate applies to more kilowatt-hours than it would for a model at the median. The modeled installed-cost range is shown in its own block on the page, with its source and date, and it is not a quote.
