U.S. CRAFTMASTER GCRL-40 2**

The 191 therms figure is computed by this site; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium pattern. For this model the UEF is 0.58. The source is the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The medium pattern represents a typical household's hot-water use, including a busy morning. A household that draws more hot water than the test assumes will use more gas than 191 therms. A household that draws less will use less. The steps behind the figure are set out in how this site calculates annual energy and cost.

The GCRL-40 2** ranks 231st lowest in energy use among the 288 models registered as a gas tank at the medium draw pattern. Its 191 therms is 6 therms above the class median of 185 therms. That puts it in the highest quarter of its class for energy use. The registry lists a rated volume of 38 gallons for this model. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. These figures describe capacity, but the class rank is based on energy use alone. A reader who needs a like-for-like match at the medium pattern can check other registered models with the same-class replacement search by model number.

This text gives no running cost for the GCRL-40 2**. The cost depends on your state's average residential gas price, so the page computes it from your ZIP code. That calculation uses 191 therms at the medium draw pattern as its energy input. The cost of the 6 therms gap to the class median also depends on that price and is not stated here. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote, and this text does not repeat it.
