Lennox WHES030L45SN240B****
0.93 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
Checking this unit's energy figure? The Lennox WHES030L45SN240B**** uses 2,413 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That is 26 kWh below the 2,439 kWh median of 163 electric tank models registered at this draw pattern.

The figure of 2,413 kWh is computed by this site, not by the registry. The registry lists this model's UEF, the ratio of hot water delivered to energy used, as 0.93. This site combines that UEF with the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The result is 26 kWh below the class median of 2,439 kWh. The model ranks 9th lowest for energy use among 163 models, which places it in the lowest quarter of its class. Both figures apply only to the test's daily draw, so actual use in a home may differ.
The low draw pattern describes a one- or two-person household. The figure of 2,413 kWh is meant for that kind of use. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 44 gallons. The rated volume is 27 gallons. A household with heavier use falls outside this draw pattern, so the figure does not describe it. Energy use at other draw patterns is not available for this model on this page. The water heater selector filters by fuel, space and size if you need to compare other options.
Running cost is not stated in the text because it depends on your own utility electricity tariff. Multiply 2,413 kWh by your rate per kilowatt-hour to get the yearly cost at the low draw pattern. The cost calculator does this from your ZIP. The methodology page explains how the annual cost is calculated. The 26 kWh gap to the class median of 2,439 kWh converts to a cost difference only at your own rate. The installed price range has its own block on this page, with its source and date. It is a modeled range, not a quote. To look up a same-class replacement, enter a model number in the replacement finder.
