0.6 UEF DOE CCD · 2026-09-19Grade F: 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).
Checking JETGLAS RG2DV40S*N-***? This gas tank uses 185 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 0 therms from the class median of 185 therms across the 288 models registered as a gas tank at this draw pattern.
Energy use per year
185 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 equal to the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 89 of 288, lowest energy first.
Solid line: this model (185 therms). Dashed line: the class median.

The figure of 185 therms was computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.6 with the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. Against the 288 models in its class, the median is 185 therms, so this model differs from the median by 0 therms. Its rank is 89th lowest energy use of 288, in the second-lowest quarter of its class. The figure holds only for the medium draw pattern, which represents a typical household on a busy morning. A household that uses more or less hot water than the test draw will use a different amount of gas, and this page does not estimate it.
The registered first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons, and the rated volume is 38 gallons. These two figures describe supply, while 185 therms describes energy use, so they answer different questions. A household whose hot-water use resembles the medium draw pattern can compare this model with its class using the 185 therms median and the 89th lowest position. A household that draws much more hot water in its busiest hour than 62 gallons should check that limit before relying on the energy figure. The selector by fuel, space and size filters models on those inputs. This page does not say how any single home's peak demand compares with the rating.
Running cost is not stated in this text because it depends on the state average residential gas price, which differs by reader. It follows from 185 therms at the medium draw pattern multiplied by the price of natural gas where you live. The cost calculator on your own ZIP applies that price to the figure, and how the annual cost is calculated sets out the method. This model sits 0 therms from the class median of 185 therms. Within the same fuel and draw pattern, a replacement uses less or more energy than this model only if its registered UEF differs from 0.6. To compare, find a same-class replacement by model number starting from RG2DV40S*N-***. The installed price range appears in its own block on this page with its source and date. It is a modeled range, not a quote.
