AMERICAN GURT-50RL 4**

The figure of 269 therms was computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.63 with the DOE test's daily hot-water draw for the high draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure describes natural gas use at that test draw only. A household that draws more or less hot water than the test assumes will use a different amount of gas. Measured use in an individual home is not available from this data, so the page does not estimate it.

Among the 414 models registered as a gas tank at the high draw pattern, this model ranks 320th lowest in energy use. That places it in the highest quarter of its class for energy use, with 269 therms against a class median of 260 therms, a gap of 9 therms above. The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 92 gallons, with a rated volume of 49 gallons. This data does not show whether that meets any one home's peak demand. To compare other fuels, spaces and sizes, use the water heater selector, or find a same-class replacement by model number.

The running cost is not written in the text because it depends on your state's average residential gas price. The page computes it from your ZIP, using 269 therms at the high draw pattern as the energy input. You can enter your own ZIP in the cost calculator. The steps behind that calculation are set out in how the annual cost is calculated. The 9 therms of extra gas use above the class median of 260 therms would be priced at the same rate, but this page does not state that amount. The installed price range appears in its own block with its source and date, as a modeled range and not a quote.
