RINNAI REHP80BM
4 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).
If you are checking RINNAI REHP80BM for a larger household, it uses 1,240 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 66 kWh below the 1,306 kWh median of 194 electric tank models.
Energy use per year
1,240 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 30 of 194, lowest energy first.
Solid line: this model (1,240 kWh). Dashed line: the class median.

UEF 4 · Grade B Price it on your ZIP
The figure of 1,240 kWh is computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 4 with the DOE test's daily hot-water draw for the high draw pattern. The source is the DOE CCD, retrieved 2026-09-19. Against the class median of 1,306 kWh, this unit sits 66 kWh lower. Its rank is 30th lowest energy use of 194, in the lowest quarter of its class. The figure applies only to the federal test's daily draw. How much hot water your household draws is not available in the registry, and a different daily draw would change the result.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 91 gallons for this unit. Its rated volume is 75 gallons. These are the figures to compare with a larger household, or one where showers and laundry overlap, which is the situation the high draw pattern describes. The comparison has limits. The 1,306 kWh median and the 30th rank cover only the 194 models registered as an electric tank at the high draw pattern. They do not describe households with a different draw pattern, and the registry data used here does not show how the unit performs outside the federal test. A lower annual figure also says nothing by itself about whether 91 gallons meets your peak demand.
Running cost is not stated in this text because it depends on your own utility electricity tariff. Multiplying 1,240 kWh, at the high draw pattern, by your rate per kilowatt-hour gives the yearly electricity cost. The same rate converts the 66 kWh gap to the class median. The cost calculator on your own ZIP does this for you, and how the annual cost is calculated sets out the method. The modeled installed-cost range is shown in its own block with its source and date, so it is not repeated here.
