U.S. CRAFTMASTER GCR-40 2**

This site calculates the 264 therms figure. The registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high draw pattern. For this model the UEF is 0.64, and the source is DOE CCD data retrieved 2026-09-19. The class here is the 414 models registered as a gas tank at the high draw pattern. The class median is 260 therms, so this unit sits 4 therms above it at the test draw. That puts it in the second-highest quarter of its class for energy use. The method behind the annual energy and cost figures sets out each step. A household that draws more or less hot water than the test assumes will use a different amount of gas. No figure for that case is available.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The 264 therms figure applies to that level of use and no other. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 80 gallons. Its rated volume is 38 gallons. A home that matches the high draw pattern can compare this unit directly with the 260 therms class median. A smaller household cannot, because the registry gives no figure for this unit at a lower draw pattern. It ranks 236th lowest energy use of 414 at the test draw, so other models in the same class use less gas. The same-class replacement search by model number finds models in this class. The selector by fuel, space and size covers other classes.

This text does not state a running cost. To get one, the page multiplies the 264 therms of natural gas by the average residential gas price in the reader's state. The page does this from your ZIP, and the cost calculator on your own ZIP runs the same calculation for any rate. The 4 therms gap to the class median is multiplied by the same price, so its cost also depends on your rate. The installed price appears in its own block with its source and date, as a modeled installed-cost range. It is not a quote, and this text does not repeat its figures. The registry data does not include actual household gas use, maintenance needs or service life.
