U.S. CRAFTMASTER GCR-50 2**

This site computed the 264 therms figure; the registry does not publish it. The calculation combines the model's UEF, the ratio of hot water delivered to energy used, of 0.64 with the DOE test's daily hot-water draw for the high draw pattern. The UEF comes from the DOE CCD registry, retrieved 2026-09-19. The figure holds only at that test draw. A home that draws more or less hot water will use more or less gas, and that amount is not available here. The class is the 414 models registered as a gas tank at the high draw pattern. Within that class, this unit ranks 236th lowest in energy use. That puts it in the second-highest quarter of its class for energy use. The steps behind the figure are set out in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 264 therms figure applies to that kind of use only. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 81 gallons. Its rated volume is 48 gallons. A plumber or seller checking a match can compare those two values with the unit being replaced. A home that needs more than 81 gallons in its busiest hour is outside what this rating covers. For a household with lighter daily use, the yearly gas figure at a lower draw is not available on this page. To compare other units in the same class, use the same-class replacement search by model number.

The text on this page does not state a running cost. The cost of 264 therms of natural gas a year depends on the reader's state average residential gas price. The page therefore computes it from the reader's ZIP instead of giving one national figure. The 4 therms gap to the class median is also priced at that local rate, and the text does not give that amount. The installed price range appears in its own block, with its source and date. That range is modeled and is not a quote. To see the yearly cost at your own rate, use the cost calculator for your ZIP.
