LOCHINVAR HPTA-66 2**
3.84 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).
Checking this water heater? The LOCHINVAR HPTA-66 2** uses 1,292 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 14 kWh below the 1,306 kWh median of 194 electric tank models.
Energy use per year
1,292 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 84 of 194, lowest energy first.
Solid line: this model (1,292 kWh). Dashed line: the class median.

UEF 3.84 · Grade B Price it on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.84 for this model. The registry does not state an annual figure. This site computed 1,292 kWh from that UEF and the DOE test's daily hot-water draw for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 194 models registered as an electric tank at this draw pattern, it ranks 84th lowest for energy use. That places it in the second-lowest quarter of its class. The gap to the class median is 14 kWh, against a median of 1,306 kWh. The method behind the annual figure is documented separately.
The high draw pattern describes a larger household, or one where showers and laundry overlap. The figure of 1,292 kWh applies only under that test draw. A household with a different daily use will see a different result, and this page does not estimate it. The registry gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 83 for this model. The rated volume is 68 gallons. Both values are as registered, not measured in your home. Households outside this draw pattern should not read 1,292 kWh as their own use. The water heater selector filters by fuel, space and size.
The running cost is not written here because it depends on your own utility electricity rate. The cost calculator applies the rate for your ZIP to 1,292 kWh. The modeled installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote. The distance of 14 kWh to the class median is an energy difference in kWh, and its cost also depends on your rate. Inlet water temperature and actual household demand are not in the data, so real annual use is unknown. To compare within the same class, find a replacement by model number.
