JETGLAS RG250L*N

The figure of 269 therms is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.63 for this model, with the daily hot-water draw the DOE test sets for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. Ordered from lowest energy use, this model is 320th of 414, which puts it in the highest quarter of its class for energy use. It sits 9 therms above the class median of 260 therms. The figure applies only at the federal test's draw; measured use in a home is not available.

The high draw pattern describes a larger household, or one where showers and laundry overlap. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 77 gallons. Its rated volume is 47 gallons. The registry does not state whether that suits a particular household's peak demand, so the value is a listed rating and not a sizing result. A household that draws less than the high pattern would use a different amount than 269 therms, and that figure is not available here. Readers who want to filter by fuel, space and size can use the water heater selector.

The running cost is not written in this text because it depends on the state average residential gas price, which differs by reader. It is the 269 therms at the high draw pattern multiplied by that price per therm. Enter your ZIP in the cost calculator to get the figure, or read how the annual cost is calculated. The same price applied to the class median of 260 therms gives the comparison point, which is 9 therms of energy below this model. A modeled installed-cost range appears in its own block on this page, with its source and date; it is not a quote and is not repeated here.
