Ruud PRO H80 T2 RH310BM

3.5 UEF DOE CCD · 2026-09-19
C

Grade C: 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 this unit against its registry entry: the Ruud PRO H80 T2 RH310BM uses 1,417 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 111 kWh above the 1,306 kWh class median for the same electric tank class.


Energy use per year

1,417 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 above the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 119 of 194, lowest energy first.

This model: 1,417 kWh

What these figures mean

The annual figure is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used. The second input is the DOE test's daily hot-water draw for this draw pattern. This model's UEF is 3.5, which gives 1,417 kWh of electricity a year. The source is DOE CCD, retrieved 2026-09-19. Among the 194 models registered as an electric tank at the high draw pattern, it ranks 119th lowest energy use of 194. That places it in the second-highest quarter of its class for energy use, 111 kWh above the class median of 1,306 kWh. The methodology page explains how the annual cost is calculated from this energy figure.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 87 gallons. The rated volume is 72 gallons. Those two figures are the ones to compare with a household's busiest hour. This model uses 111 kWh more per year than the class median, so it does not suit a reader whose priority is the lowest energy use in the class. The water heater selector filters by fuel, space and size for readers who want to compare other options. The registry data does not say how the unit performs in a particular home.

The running cost is not stated here because it depends on the utility electricity tariff at the reader's address. It is the energy figure of 1,417 kWh multiplied by that rate per kWh. The cost calculator does this from the reader's own ZIP. The 111 kWh gap to the 1,306 kWh class median uses the same test conditions for every model, so it does not change with the tariff. The figure holds only for the high draw pattern at the federal test's daily draw. A home with different hot-water use will differ, and this page has no measured value for that case. The installed price is shown in its own block as a modeled range, not a quote. For a same-class alternative, the replacement finder works from a model number.
