LOCHINVAR HPTA-50 2**
3.68 UEF DOE CCD · 2026-09-19Grade B: 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 LOCHINVAR HPTA-50 2**, this electric tank uses 883 kWh of electricity a year. That figure applies to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,648 kWh below the 3,531 kWh median for its class and ranks 48th lowest of 426.
Energy use per year
883 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 48 of 426, lowest energy first.
Solid line: this model (883 kWh). Dashed line: the class median.

UEF 3.68 · Grade B Price it on your ZIP
This site computed the 883 kWh figure; the registry does not publish it. The calculation combines the model's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the medium pattern. The registry lists this unit's UEF as 3.68, and the source is the DOE CCD, retrieved 2026-09-19. The medium pattern represents a typical household's hot-water use, including a busy morning. The yearly figure is accurate only at that test draw. A home that uses more or less hot water will use a different amount of electricity. For the steps that turn a UEF into a yearly figure, see the method behind the annual figures.
The unit ranks 48th lowest for energy use among the 426 electric tanks registered at the medium draw pattern. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons. Its rated volume is 46 gallons. The rating matters most for a home whose peak demand fits the medium pattern. If a household needs more than 65 gallons on a busy morning, the test figure does not describe its use. This page does not have this model's energy use at a heavier draw. The gap to the class median is in the summary above. To compare units of other fuels or sizes, use the selector by fuel, space and size.
This text does not state a running cost. The cost equals 883 kWh of electricity multiplied by your own utility tariff, and the registry does not hold that tariff. The cost calculator for your own ZIP works out the cost from your local rate at the same medium draw. Your actual bill will differ if your household uses more or less hot water than the DOE test assumes. The installed price appears in a separate block with its source and date. That block shows a modeled installed-cost range, not a quote. A contractor's price for the HPTA-50 2** can therefore differ from it.
