AMERICAN STANDARD WATER HEATERS PV50TLN*-65*

The 238 therms figure is computed by this site, not taken from the registry. The calculation starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.71 for this model. It then applies the DOE test's daily hot-water draw for the high draw pattern. The source data comes from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. Among the 414 gas tank models registered at the high draw pattern, this one ranks 84th lowest in energy use. That rank places it in the lowest quarter of its class for energy use. A home that draws more or less hot water than the test assumes will use a different amount of gas. The page on how the annual cost is calculated sets out each step of this method.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 107 gallons. Its rated volume is 47 gallons; both are registry values, unlike the computed annual energy figure. The 238 therms figure applies to a home whose daily use resembles that high draw pattern. For a smaller household with lighter daily use, this figure does not describe expected consumption. Homes needing a different fuel or size can compare options with the selector by fuel, space and size.

The running cost is not stated in this text, because it depends on the reader's state average residential gas price. The page computes it from your ZIP code, applied to the 238 therms yearly figure. The cost calculator on your own ZIP shows that result for your location. Because this model sits 22 therms below its class median, its gas cost at any given rate would also sit below a median-use model's. The installed price range appears in its own block, as a modeled range rather than a quote. Actual bills also depend on how much hot water your home draws, which the registry does not record.
