AMERICAN ENSB-30 1**

The 2,466 kWh figure is computed by this site. The registry does not publish it. It combines the registered UEF, the ratio of hot water delivered to energy used, of 0.91 with the DOE test's daily hot-water draw for the low pattern. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. Because the test fixes the daily draw, the figure describes the test condition, not a particular home. Energy use for this model at other draw levels is not available here, and this page does not estimate it. The method behind the annual energy and cost figures is set out on a separate page. Anyone verifying the number against a label or a quote should compare it at the same low draw pattern.

The low draw pattern corresponds to a one- or two-person household. The model lists a rated volume of 27 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. A household whose peak-hour demand is above 50 gallons falls outside what this rating covers. For energy use, it ranks 88th lowest of the 163 models in its class. That places it in the second-highest quarter of its class for energy use. Its gap to the class median, 27 kWh a year, applies at the test draw only. A reader checking alternatives in the same class can find a same-class replacement by model number.

This page does not state a running cost in the text. The cost of 2,466 kWh a year depends on your own utility's electricity tariff, and this page does not know that tariff. The cost calculator for your own ZIP applies your local rate to this model's annual energy figure. The energy figure itself does not change with the rate, because it follows from the test draw and the UEF of 0.91. An installed price range is also not published for this model. Its ratings lie outside the range the cost database's model was fitted on. The site does not stretch that range to cover them, so the installed price for this model is unknown here.
