U.S. CRAFTMASTER GCR-50 4**

This site computed the 273 therms figure; the registry does not publish it. The inputs are 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. This model's UEF is 0.62. The result holds only at that test draw. A household drawing more hot water than the test would burn more gas, and one drawing less would burn less. Against the 414 models registered as a gas tank at the high draw pattern, this unit ranks 367th for lowest energy use. That places it in the highest quarter of its class for energy use. The data comes from DOE CCD, retrieved 2026-09-19. The method behind the annual energy and cost figures is documented separately.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 84 gallons. Its rated volume is 48 gallons. A plumber or seller checking a spec sheet can match these figures against the registry listing for GCR-50 4**. The energy comparison has one limit to note. At the test draw, this unit uses 13 therms more gas per year than the class median of 260 therms. A reader who wants lower gas use at the same draw pattern can look up a same-class replacement by model number or filter water heaters by fuel, space and size.

The running cost is not stated in this text. It depends on the average residential gas price in the reader's state. The page therefore computes it from the reader's ZIP, applying that price to 273 therms per year at the high draw pattern. The running-cost calculator for your own ZIP shows the result. Because the figure rests on the test draw, actual cost would follow actual hot-water use. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. What the 13 therms gap above the class median means in cost terms is unknown until the reader's own rate is applied.
