JETGLAS RG2PV40S*N19

The 235 therms figure is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.72 for this model, and the daily hot-water draw the DOE test uses for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 414 models registered as a gas tank at this draw pattern, JETGLAS RG2PV40S*N19 ranks 50th lowest in energy use. That places it in the lowest quarter of its class, 25 therms below the 260 therms median. The rank compares test-based figures only. The steps behind the total are set out on the page about how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 235 therms figure applies only under that pattern. A household that draws less hot water would use a different amount, and this page has no value for other patterns or other fuels. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 75 gallons, and a rated volume of 38 gallons. The data here does not show whether those values cover a particular household's busiest hour, so that check needs the household's own peak use. To compare units by fuel, space and size, use the water heater selector.

The running cost is not written in the text because it depends on the state average residential gas price where the unit is installed. The cost calculator for your own ZIP applies that price to 235 therms. The result carries the same condition as the energy figure: the high draw pattern at the federal test's daily draw, not metered use in a home. A household using more or less hot water than that draw would see a different total. The modeled installed-cost range appears in its own block with its source and date, and it is not repeated here. For a same-class alternative, you can find a replacement by model number and compare it with the 260 therms class median.
