RELIANCE WATER HEATERS 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 verifying the RELIANCE WATER HEATERS HPTA-50 2**, an electric tank, it uses 883 kWh of electricity a year. That figure belongs 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 of the 426 electric tank models at that pattern.
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.

This site computed the 883 kWh figure from registry data; the registry itself does not list an annual total. The inputs are the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw. The registry lists a UEF of 3.68 for this model in the DOE Compliance Certification Database, retrieved 2026-09-19. The medium pattern models a typical household on a busy morning, so your own home's use may differ from it. See how this site calculates annual energy and cost for the method and its assumptions.
Among the 426 electric tank models at the medium draw pattern, it ranks 48th lowest for energy use. That places it in the lowest quarter of its class, with the class median at 3,531 kWh a year. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons. The rated volume is 46 gallons, which is the tank size the registry lists. A household whose daily use resembles the medium pattern is the case the 883 kWh figure describes. A household whose busiest hour needs more than 65 gallons of hot water falls outside what this rating covers. For other sizes or fuels, the water heater selector by fuel, space and size narrows the options.
The running cost is not stated here because it depends on your own utility's electricity tariff. Multiplying 883 kWh by your rate per kWh gives the yearly energy cost at the medium draw pattern. The cost calculator for your own ZIP code does this with your local tariff. Because the class median is 3,531 kWh, the 2,648 kWh gap also scales with your rate: a higher tariff widens the cost difference. The installed price range shown on this page is a modeled estimate, not a quote, and its source and date appear in that block. Actual yearly consumption in your home is not available from the registry.
