LG APHWC801M
3.9 UEF DOE CCD · 2026-09-19Grade B: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking the LG APHWC801M, an electric tank water heater, it uses 1,272 kWh of electricity a year at the federal test's draw. That figure belongs to the high draw pattern, the standard daily hot-water usage DOE tests against. It sits 34 kWh below its class median of 1,306 kWh.
Energy use per year
1,272 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is below the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 57 of 194, lowest energy first.
Solid line: this model (1,272 kWh). Dashed line: the class median.

UEF 3.9 · Grade B Price it on your ZIP
This site calculates the 1,272 kWh figure; the registry does not publish it. The calculation uses the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high draw pattern. The UEF listed for this model is 3.9, from the DOE CCD, retrieved 2026-09-19. This model is compared with the 194 models registered as an electric tank at the high draw pattern. Among them, it has the 57th lowest energy use. That puts it in the second-lowest quarter of its class for energy use, not the lowest quarter. The figure applies only at the federal test's draw. Actual use in a home with a different daily draw is not available here.
The high draw pattern fits a larger household, or one where showers and laundry overlap. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 94 gallons. Its rated volume is 72 gallons. A plumber or seller checking a high-draw home can compare these two ratings with the listing. The 1,272 kWh figure does not apply directly to a household with lighter daily use, because it is tied to the high draw pattern. This page gives no energy figure for other draw patterns. To compare other units, use the water heater selector by fuel, space and size. To stay in this unit's class, find a same-class replacement by model number.
This text does not state the running cost. The cost depends on your own utility electricity tariff, applied to the 1,272 kWh yearly use at the high draw pattern. The page calculates it from your ZIP in the running cost calculator for your ZIP. The steps behind that result are in how the annual cost is calculated. At any single tariff, this model's energy use sits below the class median of 1,306 kWh, so its running cost is lower than the median model's. How large that cost gap is depends on the tariff and is not available here. The installed price range is shown in its own block, with its source and date. That range is modeled installed cost, not a quote.
