AMERICAN GPVX-50L 2**

This model's figure of 232 therms of natural gas a year applies only to the high draw pattern, the federal test's daily hot-water draw. The registry does not publish that figure directly. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.73 for this unit, and the test's daily draw for that pattern. The source is DOE CCD, retrieved 2026-09-19. Against the class median of 260 therms, the unit sits 28 therms lower. Real use differs from the test draw, so the figure is a basis for comparison and not a prediction for any one home.

Among the 414 models registered as a gas tank at the high draw pattern, this unit has the 33rd lowest energy use, which places it in the lowest quarter of its class. The high draw pattern describes a larger household, or one where showers and laundry overlap. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 119 gallons, and the rated volume is 50 gallons. Households whose peak-hour demand is above 119 gallons fall outside what that rating covers. Figures for other draw patterns are not available on this page. To compare by fuel, space and size, use the water heater selector.

The running cost is not written here because it depends on your state's average residential gas price, and that price is not part of this model's registry record. The 232 therms figure is the fixed part of the calculation. Multiplying it by your own rate gives the yearly cost at the high draw pattern. The cost calculator does this from your ZIP code, and the methodology page explains each step. If you are checking a swap, you can find a same-class replacement by model number, which keeps the comparison at the same draw pattern. This page states no running cost for AMERICAN GPVX-50L 2**, and none is estimated.
