STATE MHE6-40R-045D 1**

This site calculated the 3,419 kWh figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the medium draw pattern. This model's UEF is 0.95. The registry data comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water than the test assumes will use a different amount of electricity. That amount is not available here. The page explains how the annual cost is calculated from this energy figure.

The rated volume is 36 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 54 gallons. DOE tests this model at the medium draw pattern, which represents typical daily household use. The 3,419 kWh figure describes a household whose use matches that pattern. If your household needs more hot water in a peak hour than 54 gallons, the figure does not describe your use. This page has no energy figure for a heavier draw. To compare heaters by fuel, space and size, use the water heater selector. To match this model number to another model in the same class, use the same-class replacement search.

Among the 426 models registered as an electric tank at the medium draw pattern, this model has the 133rd lowest energy use. The gap to the class median, stated above, and this rank both apply only at the medium draw pattern. They also apply only within this class. This text does not state the running cost, because it depends on your own utility's electricity tariff. The page calculates it from your ZIP with the cost calculator for your own ZIP. The installed-price range appears in its own block on this page, with its source and date. That range is modeled and is not a quote.
