JETGLAS RG250S*N

The 269 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. This model's UEF is 0.63. The inputs come from DOE's Compliance Certification Database (CCD), retrieved 2026-09-19. The figure therefore describes the test's daily draw, not any particular home. Use in a home that draws more or less hot water than the test is not available from this data. The method behind the annual figure sets out each step of the calculation.

The high draw pattern fits a larger household, or one where showers and laundry overlap. For that use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank. This model's first hour rating is 75 gallons. Its rated volume is 47 gallons. Both values come from the registry. The class used for comparison is the 414 models registered as a gas tank at the high draw pattern. A model tested at a different draw pattern is outside this class, so its figures are not compared here. To look across fuels, spaces and tank sizes, use the water heater selector by fuel, space and size.

A reader looking for lower gas use within this class should note this model's position. At 320th of 414 from lowest energy use, it sits in the highest quarter of its class. The gap to the class median is given above; other models in the class use less gas at the same test draw. To look for one by model number, find a same-class replacement. The running cost is not stated in this text. It depends on your state's average residential gas price. The page computes it from your ZIP, using 269 therms as the yearly use. Enter your ZIP in the cost calculator for your own ZIP to see it. The installed price range appears in its own block, with its source and date.
