STATE GCFL-50 1**
0.69 UEF DOE CCD · 2026-09-19Grade F: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are verifying the STATE GCFL-50 1** gas tank, it uses 245 therms of gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 15 therms below the 260 therms median of the 414 gas tank models registered at that draw pattern.
Energy use per year
245 therms a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.
That is below the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 130 of 414, lowest energy first.
Solid line: this model (245 therms). Dashed line: the class median.

This site computes the 245 therms figure; the registry does not list it. 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 this model the UEF is 0.69, taken from the DOE Compliance Certification Database (CCD) and retrieved 2026-09-19. The 414 gas tank models at the high draw pattern are ranked by energy use. On that list, this model is 130th from the lowest. That places it in the second-lowest quarter of its class for energy use. The steps behind the figure are set out on the page about how the annual cost is calculated.
The high draw pattern describes 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 78 gallons. Its rated volume is 49 gallons. The 245 therms figure applies to a home whose daily hot-water use matches that pattern. A home that draws more or less hot water each day will use a different amount of gas. This page does not give that amount. The rank also holds only among gas tank models at the high draw pattern. This data has no comparison with other heater types or fuels. To compare across those, use the water heater selector by fuel, space and size.
The text on this page does not state a running cost. The cost of 245 therms of natural gas a year depends on your state's average residential gas price. For that reason, the page computes the cost from your ZIP. Any cost difference from the 15 therms gap below the class median also depends on that rate, and it is not stated here. The installed price range has its own block, with its source and date. It is a modeled range, not a quote. To apply your own rate to this model, open the water heater cost calculator for your ZIP. If you are matching a unit already in place, find a same-class replacement by model number.
