STATE ENT-55 1**

The 3,493 kWh figure is computed by this site, not published by the registry. It combines the model's UEF, the ratio of hot water delivered to energy used, which the registry lists as 0.93. The site pairs that UEF with the daily hot-water draw the DOE test sets for the medium pattern. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The medium pattern stands for a typical family household with a busy morning of hot-water use. Your household may draw more or less hot water than the test assumes. In that case your yearly electricity use will differ from 3,493 kWh, and this page has no figure for that case. The steps behind the annual figure are set out in how the annual cost is calculated.

This unit holds 55 gallons. It has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 72 gallons. That rating is the limit to check against your busiest hour. A household whose peak hour stays within 72 gallons fits the conditions behind the 3,493 kWh figure. A household that needs more than 72 gallons in one hour is outside what this rating covers. The registry gives no energy figure for this model at a heavier draw pattern, so that value is not available here. This page also holds no data on gas or heat-pump units. Those types are listed in the selector by fuel, space and size.

The 38 kWh gap below the class median, given above, is an energy figure, not a cost. What that gap and the full 3,493 kWh cost you depends on your utility's electricity tariff. For that reason this text names no running cost. The page computes it from your ZIP in the cost calculator for your own ZIP. The rank given above places this model below the class median but outside the lowest quarter of its class. The installed-price range on this page sits in its own block with its source and date. It is a modeled range, not a quote. To check other units in the same class, use the same-class replacement search by model number.
