JETGLAS RG2DV50S*N-***

0.64 UEF DOE CCD · 2026-09-19
G

Grade G: 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 verifying this JETGLAS RG2DV50S*N-*** gas tank, the figure is 264 therms of natural gas a year at the high draw pattern. The draw pattern, the standard daily hot-water usage DOE tests against, is high for this model. That is 4 therms above the class median of 260 therms.


Energy use per year

264 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 above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 236 of 414, lowest energy first.

This model: 264 therms

Solid line: this model (264 therms). Dashed line: the class median.

What these figures mean

The figure of 264 therms of natural gas a year comes from this site, not from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.64. That value is combined with the DOE test's daily hot-water draw for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. The class is the 414 models registered as a gas tank at the high draw pattern, with a median of 260 therms a year. This model is 4 therms above that median. Its rank is 236th lowest energy use of 414, in the second-highest quarter of its class for energy use. Read how the annual cost is calculated for the full method.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The first hour rating, the gallons of hot water available in the first hour from a full tank, is listed for this model. It is 77 gallons, and the rated volume is 47 gallons. This unit is registered under the high draw pattern, so the energy figure applies to a household of that kind. For a household with a lower draw pattern, 264 therms does not apply. Your own hot-water use is not available in the registry data. If your aim is energy use below the class median of 260 therms, this model does not meet it at 264 therms a year. The water heater selector by fuel, space and size narrows other options.

The running cost is not stated here, because it depends on the state average residential gas price where you live. To check it, multiply 264 therms by your own price per therm. The cost calculator on your own ZIP does this for you. That figure holds only for natural gas at the high draw pattern. Whatever the rate, the cost scales with the 264 therms figure, which sits 4 therms above the class median of 260 therms. The installed price range appears in its own block with its source and date, so it is not restated here. To look for a same-class unit, find a replacement by model number, starting from RG2DV50S*N-***.
