Rheem PROG50-40N RH67 PDV

This site calculated the 245 therms figure; it is not taken directly from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. This model's rated UEF is 0.69, from the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at that test draw. A home that uses more or less hot water will use more or less gas. Among the 414 gas tank models at the high draw pattern, this one ranks 130th lowest for energy use. That places it in the second-lowest quarter of its class for energy use. The page on how the annual cost is calculated sets out each step.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, this model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 82 gallons. Its rated volume is 47 gallons. For a home that fits this pattern, the 245 therms figure reflects the daily usage DOE assumed in its test. It does not show how the model performs at other draw levels. To compare it with other gas tank models at the same draw pattern, use the same-class replacement search by model number.

A smaller household that draws less hot water than the high pattern should not treat 245 therms as its own yearly use. This page does not have an energy figure for lower draw patterns. The running cost is not given in this text either. It depends on your state's average residential gas price, so the page calculates it from your ZIP in its own block. Your gas price also sets what the 15 therms gap below the 260 therms class median is worth. The cost calculator for your own ZIP shows that result. The installed price range appears in a separate block. It is a modeled range with its source and date, not a quote.
