Rheem PRO+G50-47P RH62 PDV

This site computes the 260 therms figure; the registry does not state it. It starts from the registry's UEF, the ratio of hot water delivered to energy used. For this model, the UEF is 0.65. The site applies that ratio to the daily hot-water draw that the DOE test sets for the high draw pattern. The result holds only at that test draw. A household that draws more or less hot water each day will use more or less gas, and that amount is not available here. The source is the DOE CCD, retrieved 2026-09-19. The page sets out how the annual energy and cost figures are calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 81 gallons. Its rated volume is 48 gallons. Among the 414 gas tank models at the high draw pattern, it ranks 204th lowest in energy use. That rank matches its median position noted above. A home whose busiest hour needs more than 81 gallons falls outside what this rating covers. The same applies to a home whose daily use is well below the test draw. To compare models on other terms, use the water heater selector by fuel, space and size.

The running cost is not stated in this text. It depends on your state's average residential gas price. When you enter your ZIP, the page multiplies 260 therms of natural gas by that price. You can also run the cost calculator on your own ZIP. The class median is also 260 therms. At the same gas price and the same test draw, a same-class model at that median would have the same running cost. The installed-cost range on this page is modeled and is not a quote. To match this unit with another model in the same class, find a same-class replacement by model number.
