Rheem PRO+G50-50N RH67 PD

The registry does not list the 245 therms figure. This site calculated it from the model's UEF, the ratio of hot water delivered to energy used, which the registry lists as 0.69. The calculation uses that value with the DOE test's daily hot-water draw for the high draw pattern. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The result covers use at that test draw only. It does not apply to a home that uses more or less hot water each day than the test assumes. The registry gives no figure for such a home. The steps from UEF to yearly energy and cost are set out in how the annual cost is calculated.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The registry lists this model's first hour rating, the gallons of hot water available in the first hour from a full tank, as 84 gallons. Its rated volume is 48 gallons. At the test draw, it ranks 130th lowest in energy use among the 414 gas tank models at the high draw pattern. That puts it in the second-lowest quarter of its class. A plumber checking a swap can find a same-class replacement by model number. That way the comparison stays within gas tanks tested at the high draw pattern.

The rank and the gap to the class median only compare this model with gas tank models tested at the high draw pattern. They do not compare it with other fuels, tankless units or other draw patterns. This page has no data for those comparisons. The selector by fuel, space and size covers those other groups. This text does not state the running cost at 245 therms a year. It depends on your state's average residential gas price, so the page calculates it from your ZIP in the cost calculator for your own ZIP. The installed price range has its own block, with its source and date. That range comes from a cost model and is not a quote.
