DIYCOOL ACIQ-50G-HP-WH
3.75 UEF DOE CCD · 2026-09-19Grade A: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking the DIYCOOL ACIQ-50G-HP-WH, it uses 866 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,665 kWh below the 3,531 kWh median for the 426 electric tank models registered at this draw pattern.
Energy use per year
866 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 21 of 426, lowest energy first.
Solid line: this model (866 kWh). Dashed line: the class median.

UEF 3.75 · Grade A Price it on your ZIP
The 866 kWh figure is not printed in the registry. This site computed it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used. The second is the DOE test's daily hot-water draw for the medium pattern. For the ACIQ-50G-HP-WH, the registered UEF is 3.75, from the DOE CCD, retrieved 2026-09-19. At that UEF, the model ranks 21st lowest for energy use among 426 electric tanks at the medium draw pattern. That rank places it in the lowest quarter of its class. The steps behind the annual figure are set out in how the annual energy and cost figures are calculated. If a spec sheet lists a different UEF than 3.75, the annual figure on this page will not match it.
In DOE's test, the medium draw pattern represents a typical household. So the 866 kWh figure applies to homes whose daily hot-water use is close to that pattern. Two ratings describe capacity. The first is the first hour rating, the gallons of hot water available in the first hour from a full tank. For this model it is 69 gallons. The rated volume is 47 gallons. A home that uses much more hot water than the medium pattern should not expect 866 kWh a year. This page has no energy figure for this model at other draw patterns. To compare other electric tanks for that case, use the water heater selector by fuel, space and size. You can also run a same-class replacement search by model number.
This text does not state a running cost. The cost depends on your own utility's electricity tariff, so the page works it out from your ZIP. It applies your rate to the 866 kWh yearly figure at the medium draw pattern. You can run the same step in the cost calculator on your own ZIP. On a flat rate, the cost gap to the class median is the 2,665 kWh energy gap noted above multiplied by that rate. On a tiered or time-of-use tariff, the calculator result is the figure to check. The installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote from an installer. This text does not estimate either figure.
