STATE GCR-50 4**

The 273 therms figure is computed by this site, not taken from the registry. 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 high draw pattern. For the STATE GCR-50 4**, the registry lists a UEF of 0.62, retrieved from the DOE CCD on 2026-09-19. Among the 414 gas tank models at the high draw pattern, it has the 367th lowest energy use of 414. That places it in the highest quarter of its class for energy use. The figure holds only at the federal test's daily draw; use at a different draw is not available here. The steps behind the number are set out in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 84 gallons. Its rated volume is 48 gallons. A plumber or seller checking a match for that kind of household can confirm these values against the registry listing. A reader whose priority is lower gas use at this draw pattern should note the 13 therms per year above the class median of 260 therms. Models closer to or below that median can be looked up with a same-class replacement search by model number. A search by fuel, space and size is available in the water heater selector.

This page does not state a running cost in the text. The cost of 273 therms of natural gas a year depends on the reader's state average residential gas price. The page computes it from the reader's ZIP instead, so no cost figure is given here. The 13 therms gap to the class median also costs more or less depending on that same rate. To see the result for your own rate, use the cost calculator on your ZIP. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. How long this unit lasts and how it performs in a given home are not in the registry data, so both are unknown here.
