The 3,531 kWh figure is computed by this site, not taken from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. That value is combined with the DOE test's daily hot-water draw for the medium pattern. The source is the DOE CCD, retrieved 2026-09-19. The medium pattern stands for a typical household of a few people with a busy morning. The figure holds only at that test draw. A household that uses more or less hot water will see a different yearly total, and this page does not have that value. The steps are set out in how this site calculates annual energy and running cost.

This model lists a rated volume of 40 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. The figures describe a household whose morning demand stays within that rating and whose daily use is close to the medium pattern. For demand above 64 gallons in the first hour, the registry data gives no performance figure. Among the 426 models in its class, it ranks 213th lowest in energy use. Models ranked ahead of it use the same or less energy at the same test draw. To compare them, use the same-class replacement search by model number or the water heater selector by fuel, space and size.

This page does not state a running cost in the text. The cost of 3,531 kWh a year depends on your own utility's electricity tariff. The page therefore computes that cost from your ZIP rather than from a single national figure. Enter it in the running cost calculator for your own ZIP to see the result at your rate. This model's use equals the class median, with a difference of 0 kWh. At the medium draw and any given rate, its running cost therefore matches a model at the class median. The installed price range sits in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
