U.S. CRAFTMASTER GCRH-40 4**

This site computed the figure of 188 therms per year. The registry does not publish it. The calculation 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 draw pattern. For the U.S. CRAFTMASTER GCRH-40 4**, the UEF is 0.59. It comes from the DOE CCD, retrieved on 2026-09-19. The annual figure applies only at that federal test draw. It does not describe gas use in a home that draws a different amount of hot water each day. This page does not have a measurement of real household use for this model. The steps behind the figure are on the page explaining how the annual cost is calculated.

This model is compared with the 288 models registered as a gas tank at the medium draw pattern. At the test draw, it ranks 186th for lowest energy use among those 288 models. That places it above the class median given at the top of this page. Two capacity figures appear next to that ranking. The rated volume is 38 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons. These figures fit a home whose daily use is close to the medium draw pattern. If you need a different fuel, space or size, compare options in the water heater selector by fuel, space and size.

This text does not state a running cost. The cost depends on your state's average residential gas price, so the page calculates it from your ZIP. To apply your own rate to 188 therms a year at the medium draw pattern, use the water heater cost calculator for your ZIP. This model is less suited to readers who want lower gas use within the same class. It ranks 186th of 288, so the gas tank models ranked ahead of it use less energy at the test draw. To look for one of those models, find a same-class replacement by model number. The installed price range on this page is a modeled range with its own source and date. It is not a quote.
