JETGLAS RG2D40S*N
0.64 UEF DOE CCD · 2026-09-19Grade E: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking this model's rated gas use, here is the registry-based figure. The JETGLAS RG2D40S*N, a gas tank heater, uses 173 therms a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 12 therms below the 185 therms median of the 288 gas tank models at that pattern.
Energy use per year
173 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 44 of 288, lowest energy first.
Solid line: this model (173 therms). Dashed line: the class median.

This site computes the 173 therms figure. The registry does not publish it. The calculation combines the model's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw in the DOE test for the medium draw pattern. This unit's UEF is 0.64, taken from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The annual figure holds only at that test draw. A household that uses more hot water each day than the test assumes will use more gas than 173 therms. A household that uses less will use less gas. The registry does not record how large that difference would be, so it is not available here. The steps behind the figure are set out in how the annual cost is calculated.
The JETGLAS RG2D40S*N ranks 44th lowest in energy use out of 288 gas tank models at the medium draw pattern. Its 173 therms is 12 therms under the class median of 185 therms. This comparison covers rated gas use only. It says nothing about service life or installation. For a household at this pattern, capacity is the other thing to check. The tank 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 62 gallons. If a home uses more than 62 gallons in its busiest hour, that is more than this rating covers. The selector by fuel, space and size can filter for a higher first hour rating.
This text does not state the running cost, because it depends on your state's average residential natural gas price. The page calculates it from your ZIP code. Two readers in different states will therefore see different costs for the same RG2D40S*N at 173 therms. The 12 therms gap to the class median also becomes a cost difference only at your own rate. The installed-price block on this page shows a modeled range with its own source and date. It is not a quote. To check the figure for another ZIP, use the cost calculator on your own ZIP.
