AMERICAN GPVL-40 2**

The figure of 165 therms is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.67 for this model, with the daily hot-water draw the DOE test assigns to the medium draw pattern. The source data come from the DOE CCD, retrieved 2026-09-19. The fuel is natural gas, and the figure holds only at that test draw. It is not a measured consumption for this unit in a home, and a household that uses hot water differently will see a different total. The calculation is described in how the annual cost is calculated.

Among the 288 models registered as a gas tank at the medium draw pattern, this unit ranks 20th lowest for energy use, which places it in the lowest quarter of its class. Its 165 therms sits 20 therms below the class median of 185 therms. That comparison is valid only inside this class; a different fuel or draw pattern is not comparable. The unit has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 73 gallons, and a rated volume of 38 gallons. The registry data do not show whether that capacity meets a particular household's peak demand. The selector by fuel, space and size can narrow that question.

The running cost of the AMERICAN GPVL-40 2** is not written here. It depends on your state average residential gas price, and no rate is assumed on this page. At the test draw, the 165 therms of natural gas is the same for every reader; only the price per therm changes. Enter your ZIP in the cost calculator on your own ZIP to get the running cost at your rate. The installed price range appears in its own block, with its source and date, as a modeled range and not a quote. If you are comparing this unit with a possible swap, find a same-class replacement by model number and check it against the 185 therms class median.
