RINNAI REHP65
3.9 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 verifying the RINNAI REHP65, an electric tank, it uses 1,272 kWh a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 34 kWh below the class median of 1,306 kWh, and ranks 57th lowest of 194 models.
Energy use per year
1,272 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 57 of 194, lowest energy first.
Solid line: this model (1,272 kWh). Dashed line: the class median.

UEF 3.9 · Grade B Price it on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.9 for the REHP65. This site did not read the annual figure from the registry. It computed 1,272 kWh from that UEF and the DOE test's daily hot-water draw for the high draw pattern, using DOE CCD data retrieved 2026-09-19. Against the 194 models registered as an electric tank at the high draw pattern, the median is 1,306 kWh. This model sits 34 kWh below it, at 57th lowest, which is the second-lowest quarter of its class for energy use. The comparison holds only at the test's draw.
The high draw pattern describes a larger household, or one where showers and laundry overlap. The listed first hour rating, the gallons of hot water available in the first hour from a full tank, is 80 gallons, and the rated volume is 60 gallons. Those two figures, not the 1,272 kWh, are what to compare with your own busiest hour. A household whose use differs from the test's draw cannot read the annual figure directly, and this page has no value for other draw patterns. To filter by fuel, space and size, use the water heater selector, or find a same-class replacement by model number.
The running cost is not stated here because it depends on your utility's electricity rate. The annual energy of 1,272 kWh is the quantity to multiply by that rate per kilowatt-hour, and it applies only at the high draw pattern. The cost calculator for your own ZIP does this with your tariff. The steps behind the annual cost are in the methodology for water heater annual cost. The 34 kWh gap to the class median converts to cost the same way, at your rate. The modeled installed-cost range appears in its own block on the page, with its source and date. It is not a quote, and its figures are not repeated in this text.
