This site calculated the 3,493 kWh figure; the registry does not publish it. The starting point is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.93 for this model. The calculation then applies the DOE test's daily hot-water draw for the medium draw pattern. That pattern stands for a typical three- or four-person household on a busy morning. The figure is valid only at the federal test's daily draw. If a home uses a different amount of hot water, its annual figure will be different, and this page does not estimate it. The UEF comes from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The calculation steps are explained in how the annual energy and cost figures are calculated.

The model ranks 153rd lowest for energy use among the 426 models registered as an electric tank at the medium draw pattern. That puts it in the second-lowest quarter of its class, not at the lowest end. Its rated volume is 45 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. The class comparison applies to a household whose use is close to the medium pattern. It does not apply to a home whose busiest hour needs more than 62 gallons. Units outside the electric tank class at the medium draw pattern are not part of this ranking. To compare within the same class, use find a same-class replacement by model number.

This text gives no running cost. The cost of 3,493 kWh a year depends on the reader's own electricity rate, and rates vary from one utility to another. The cost calculator for your own ZIP works out the cost from the reader's ZIP, using the same medium-pattern energy figure. Like the energy figure, that cost applies at the federal test's daily draw, not to a household's measured use. The 38 kWh gap to the class median of 3,531 kWh carries over into cost at whatever rate the reader enters. This text does not state that gap in money. The installed price range is shown in its own block, with its source and date. It is a modeled installed-cost range, not a quote, and this text does not repeat its figures.
