LG APHWC502D
4.2 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).
For a larger household, or one where showers and laundry overlap, the LG APHWC502D uses 1,181 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 125 kWh below the 1,306 kWh class median across 194 models.
Energy use per year
1,181 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 8 of 194, lowest energy first.
Solid line: this model (1,181 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

- Compressor operating range (ENERGY STAR)
- the air temperatures around the unit in which its heat pump runs; outside this range the heat pump stops
- Dimensions (ENERGY STAR)
- the unit's filed height, width, depth or tank diameter, in inches
- Input voltage and maximum current (ENERGY STAR)
- the circuit voltage the unit is certified on and the most current it draws

UEF 4.2 · Grade B Price it on your ZIP
The figure of 1,181 kWh is computed by this site, not published by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 4.2 for this model. The DOE test's daily hot-water draw for the high draw pattern supplies the other input. The source is the DOE CCD, retrieved 2026-09-19. Among the 194 models registered as an electric tank at the high draw pattern, this unit ranks 8th lowest for energy use. That places it in the lowest quarter of its class. The figure describes the test's draw, so a household that uses more or less hot water than the test will see a different annual result.
The high draw pattern fits a larger household, or one where showers and laundry overlap. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 81 gallons. Its rated volume is 53 gallons. The energy figure of 1,181 kWh does not show whether 81 gallons covers your busiest hour, so check that rating against your own peak demand. A household with a smaller draw than the test is not described by this page. An installed price range is not published, because this model's ratings lie outside the range the cost database's model was fitted on. To narrow options by fuel, space and size, use the water heater selector.
Running cost is not stated here because it depends on your own utility electricity tariff. Multiply 1,181 kWh by your rate per kilowatt-hour, or enter your ZIP in the cost calculator, which does this for you. The gap of 125 kWh to the class median of 1,306 kWh is an energy difference. What it is worth in money depends on the same rate. The steps behind the calculation are described in how the annual cost is calculated. To compare this APHWC502D with other models in the same class, you can find a same-class replacement by model number.
