STATE ENSB-30 1**

The figure of 2,466 kWh is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.91 for this model. It also used the DOE test's daily hot-water draw for the low draw pattern. The DOE CCD record was retrieved on 2026-09-19, and the calculation method for the annual cost is documented separately. The class is the 163 models registered as an electric tank at the low draw pattern. Its median is 2,439 kWh, so this model sits 27 kWh above it. Ranked from lowest energy use, it is 88th of 163, in the second-highest quarter of its class for energy use. The comparison holds only at the low draw pattern.

The registry lists a rated volume of 27 gallons and a first hour rating, the gallons of hot water available in the first hour from a full tank, of 50 gallons. The low draw pattern corresponds to a one- or two-person household, so 2,466 kWh applies to that level of use and to no other. A household with heavier use is tested under a different draw pattern, and this page has no figure for it. Those readers should not take 2,466 kWh as their own annual use. To compare by fuel, space and size, the water heater selector covers those inputs. To look for a unit of the same class, find a replacement by model number.

The running cost is not stated here because it depends on your own utility electricity tariff. The energy figure of 2,466 kWh is fixed by the test conditions, but its cost changes with the rate you pay. The 27 kWh gap to the class median is also an amount of energy, so its cost depends on the same rate. The cost calculator on your own ZIP applies your tariff to the annual energy figure. The installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and that range is not stretched past its limits. No estimate of installed price is available.
