U.S. CRAFTMASTER GCRL-40 4**

The 191 therms figure is calculated by this site; the registry does not list it. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.58 for this model. That ratio is then applied to the DOE test's daily hot-water draw for the medium draw pattern. The source is the DOE CCD, retrieved on 2026-09-19. So the figure holds only at the test's draw. A household that uses more or less hot water than that pattern will have a different yearly total, and this page does not know that amount. The steps from the registry value to a yearly figure are set out in how the annual cost is calculated.

Within its class, this model ranks 231st lowest energy use of 288. That places it among the higher-use models of the gas tank class at the medium draw pattern, at the test's draw. The model has a rated volume of 38 gallons. It also has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 67 gallons. The medium draw pattern describes a typical household's daily use. The energy figure applies most directly to a home whose use is close to that pattern. If you want a lower yearly figure in the same class, you can look up models below the class median with a same-class replacement search by model number.

This text does not state a running cost. It depends on your state's average residential natural gas price, so the page computes it from your ZIP. That calculation multiplies 191 therms by your rate. The class median of 185 therms gives a comparison point at the same rate, so the gap described above carries into the cost. You can see both results with the cost calculator for your own ZIP. The installed price range is shown in a separate block with its source and date. It is a modeled range, not a quote. Your household's actual hot-water use is not known here and will change the result.
