JETGLAS RG2PV50T*N19

The 235 therms figure is not a registry field. This site computes it from the registry's UEF, the ratio of hot water delivered to energy used. It then applies the DOE test's daily hot-water draw for the high draw pattern. The registry lists a UEF of 0.72 for the RG2PV50T*N19, retrieved from the DOE CCD on 2026-09-19. Among the 414 models in its class, it ranks 50th lowest for energy use. That places it in the lowest quarter of its class for energy use. A household that draws more or less hot water than the test assumes will use a different amount of gas. The page on how the annual energy and cost are calculated sets out each input.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 235 therms figure only holds for that level of use, so it is the right reference when the home fits that description. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 75 gallons. Its rated volume is 48 gallons. A smaller household with lighter hot-water use falls outside this draw pattern, and the 235 therms figure would not describe its gas use. Nor does the figure apply to a home without a natural gas supply, since the rating is for gas. To compare other sizes and fuels, the selector by fuel, space and size lists models by those inputs.

This text gives no running cost for the model, because the cost depends on the state average residential gas price where you live. The page computes that cost from your ZIP, applying your state's rate to 235 therms of natural gas a year. You can check that figure with the cost calculator on your own ZIP. The 25 therms gap to the class median of 260 therms is an energy difference, and its value in money depends on that rate. The installed price range elsewhere on this page is a modeled installed-cost range, not a quote, and it carries its own source and date. How this heater performs in a particular home is not recorded in the registry, so it is not available here.
