STATE ENS-30 1**

The 2,522 kWh figure does not appear in the registry itself. This site computes it from two inputs. The first is the model's UEF, the ratio of hot water delivered to energy used, listed as 0.89. The second is the DOE test's daily hot-water draw for the low pattern. The figure holds only at that test draw. It does not describe a household whose daily draw differs from the test's. The underlying rating comes from the DOE CCD, retrieved 2026-09-19. Sorted from lowest energy use, this model ranks 143rd of the 163 low-draw electric tanks. That places it in the highest quarter of its class for energy use. The steps behind the annual energy and cost figures are set out separately.

The low draw pattern stands for a one- or two-person household. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 47 gallons. Its rated volume is 27 gallons. A household whose daily use matches the low pattern is the case the 2,522 kWh figure describes. A larger household falls outside the tested condition. Its annual energy use for this model is not available from this data. A reader checking whether a lower-use unit exists at the same pattern can compare against the other registered models in the class. The same-class replacement search by model number starts from a model number such as ENS-30 1**.

This page states no running cost in the text. That cost depends on the 2,522 kWh test-draw figure and on your own utility's electricity tariff. Tariffs differ by utility, so no single cost applies to every reader. The running-cost calculator for your own ZIP applies your local rate to this model's figure. The 83 kWh gap to the class median, described above, also turns into a cost gap that depends on that rate. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on. This site does not extend that range beyond its fitted limits, so installed cost for the STATE ENS-30 1** is unknown here.
