JETGLAS RG240S*N

This model's annual figure is 191 therms of natural gas. This site computed it; the registry does not publish it. The inputs are the registry's UEF, the ratio of hot water delivered to energy used, which is 0.58 for this model, and the federal test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 288 models registered as a gas tank at the medium draw pattern, this one has the 231st lowest energy use. That places it in the highest quarter of its class for energy use. The class median is 185 therms, and this model sits 6 therms above it.

The figure applies to a household that matches the medium draw pattern: a typical three- or four-person household, on a busy morning. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 69 gallons, and its rated volume is 38 gallons. This page does not judge whether that capacity meets a particular household's needs. Energy use at any other draw pattern is not available here. Someone comparing on energy use alone should note the 6 therms difference from 185 therms. The selector by fuel, space and size covers other options, and you can find a same-class replacement by model number.

The running cost is not written in this text because it depends on your state's average residential gas price. The cost calculator on your own ZIP applies that price to 191 therms, and how the annual cost is calculated sets out the method. A different rate changes the result, while the energy figure stays tied to the federal test's draw. The 6 therms gap to the class median becomes a cost difference only at a specific rate, which this page does not assume. The installed price range appears in its own block with its source and date, as a modeled installed-cost range, not a quote. Measured use in a given home is not available.
