AMERICAN GCR-50 2**

0.64 UEF DOE CCD · 2026-09-19
G

Grade G: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).

If you are checking this unit's energy figure, AMERICAN GCR-50 2** uses 264 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 4 therms above the class median of 260 therms for the 414 gas tank models at this draw pattern.


Energy use per year

264 therms a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.

That is above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 236 of 414, lowest energy first.

This model: 264 therms

What these figures mean

The figure of 264 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, with the daily hot-water draw the DOE test assigns to the high draw pattern. The registry lists a UEF of 0.64 for this model. The source is DOE CCD, retrieved 2026-09-19. Among the 414 models registered as a gas tank at this draw pattern, this one sits 4 therms above the class median of 260 therms. It ranks 236th lowest in energy use of 414, which places it in the second-highest quarter of its class for energy use. The calculation method is documented separately.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 81 gallons, and a rated volume of 48 gallons. A verifier can compare those two values with the peak-hour demand of the household in question. The figure of 264 therms does not describe a household whose hot-water use differs from the test draw, and this page gives no estimate for another draw pattern. The water heater selector filters by fuel, space and size when one of those is the open question.

The running cost is not stated in this text. It depends on the state average residential gas price, and this page does not estimate it. Multiplying 264 therms by the reader's own price per therm gives the yearly cost at the federal test's draw. The cost calculator does this from a ZIP code. At the same rate, the 4 therms gap to the 260 therms median converts to a cost difference in the same way. The modeled installed-cost range for AMERICAN GCR-50 2** appears in its own block with its source and date, and it is not repeated here.
