JETGLAS RG2F50S*N
0.68 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 checking the JETGLAS RG2F50S*N, it uses 249 therms of natural gas a year. That figure is for the high draw pattern, the standard daily hot-water usage DOE tests against. It is 11 therms below the class median of 260 therms among 414 gas tank models.
Energy use per year
249 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 164 of 414, lowest energy first.
Solid line: this model (249 therms). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.68 for this model. The registry does not publish an annual energy figure. This site computed it from that UEF and the daily hot-water draw in the DOE test for this draw pattern. See how the annual cost is calculated for the method. The result is 249 therms of natural gas, from DOE CCD data retrieved 2026-09-19. Among the 414 models registered as a gas tank at the high draw pattern, it has the 164th lowest energy use. That puts it in the second-lowest quarter of its class. Its figure sits 11 therms below the class median of 260 therms.
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 76 gallons. The rated volume is 48 gallons. The 249 therms figure applies only at the high draw pattern. The data does not give a figure for any other draw pattern. It also does not show whether 76 gallons covers your own peak demand. To compare fuel, space and size, use the water heater selector. To look for a same-class model, find a replacement by model number.
The running cost is not stated here. It depends on the average residential gas price in your state, and this page does not estimate it. Enter your ZIP in the cost calculator to apply your own rate to the 249 therms. The 11 therms gap to the class median is a difference in gas use, not in cost. Its effect on your bill is not available in this data. The rank of 164th lowest applies only to the 414 models compared at the high draw pattern. The installed-cost range is shown in its own block with its source and date. It is a modeled range, not a quote, and this text does not restate it.
