STATE MHE6-40RW-035D-1**

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.91 for this model. The site combined that value with the DOE test's daily hot-water draw for the low pattern to get 2,466 kWh of electricity a year. The registry does not publish this annual figure; it was computed here, using DOE CCD data retrieved 2026-09-19. Among the 163 electric tank models in its comparison group, it ranks 88th lowest in energy use. That is the second-highest quarter of its class, with use 27 kWh above the class median of 2,439 kWh. The data gives the median and rank only, so the spread of the class is not available.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 40 gallons for this model. The rated volume is 36 gallons. The 2,466 kWh figure applies only to the low draw pattern, which represents a small household. It suits a reader checking a unit that serves that kind of use against the class median of 2,439 kWh. It does not describe a household with a larger daily hot-water draw, and the data gives no annual energy for other draw patterns. An installed price range is not published, because this model's ratings lie outside the range the cost database's model was fitted on. The water heater selector filters by fuel, space and size.

The running cost is not stated in the text, because it depends on the electricity tariff the reader pays. It is the 2,466 kWh figure multiplied by that rate, so the same model costs different amounts in different places. The cost calculator applies the rate for the reader's own ZIP code, and how the annual cost is calculated sets out the method. The figure assumes the federal test's daily draw; actual use in a home is not available here and may differ from 2,466 kWh.
