STATE GCBL-40 4**

This site calculates the 194 therms figure; the registry does not publish 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 medium draw pattern. For this model the UEF is 0.57, taken from the DOE Compliance Certification Database and retrieved on 2026-09-19. There are 288 models registered as a gas tank at the medium draw pattern. Ranked from lowest energy use, this model is 278th. That puts it in the highest quarter of its class for energy use. The page on how the annual cost is calculated sets out the steps behind the calculation.

The medium draw pattern describes a typical household's daily hot-water use, including a busy morning. This unit has a rated volume of 38 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 68 gallons. The 194 therms figure applies to a household whose use matches that test pattern. A household using much more or less hot water than the test assumes will use a different amount. That amount is not available here. The rank above shows that most models in this class use less gas at the medium draw pattern. To compare other units, the selector by fuel, space and size filters on those three factors.

The running cost is not written here because it depends on your state's average residential gas price. The cost calculator on your own ZIP applies that price to the 194 therms figure at the medium draw pattern. That same rate also sets the yearly cost of the 9 therms gap above the class median. An installed price range for this model is not published. The cost database's model was fitted on a range of ratings, and this model's ratings lie outside it. The page does not stretch that range to cover them. If you are checking a replacement, you can find a same-class replacement by model number.
