LOCHINVAR ENLB-50 1**

This site calculated the 3,493 kWh figure; it does not come from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. For the ENLB-50 1**, the UEF is 0.93, from DOE CCD data retrieved 2026-09-19. Among the 426 electric tank models at the medium draw pattern, it ranks 153rd lowest in energy use. The gap to the class median is 38 kWh a year. That places the model below the middle of its class, not at either end. The page on how the annual cost is calculated sets out the steps behind this figure.

The medium draw pattern stands for the hot-water use of a typical household of average size. The 3,493 kWh figure applies only to that pattern's daily draw. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 60 gallons. Its rated volume is 44 gallons. A household that uses more or less hot water than the test day falls outside this figure. Energy use at other draw levels is not available here. A household whose busiest hour needs more than 60 gallons is also outside what this rating covers. To compare other units, use the selector by fuel, space and size.

Running cost is not stated in this text because it depends on your own utility's electricity tariff. Your tariff applies to the 3,493 kWh a year, and the cost calculator on your own ZIP works out the result. The same limit applies to the 38 kWh gap from the class median. What that gap is worth in a year depends on your rate, so this text cannot give it. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote. To check this unit against another model in its class, find a same-class replacement by model number.
