JETGLAS RG2DV50H*N-***

The figure of 264 therms is not a registry entry. This site computed it from the registry's UEF and the DOE test's daily hot-water draw for the high draw pattern, and the source data is DOE CCD, retrieved 2026-09-19. UEF, the ratio of hot water delivered to energy used, is 0.64 for the JETGLAS RG2DV50H*N-***. The calculation is set out on the methodology page. Among the 414 gas tank models in its class, this unit ranks 236th lowest for energy use, which places it in the second-highest quarter. Its 264 therms sits 4 therms above the class median of 260 therms. That difference applies at the test draw only.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 96 gallons and a rated volume of 46 gallons for this model. A household that matches that pattern is the one this energy figure describes. A household that uses much less hot water than the test draw may not see 264 therms, and the registry data does not say what such a household would use. Readers who want the lowest energy use in the class should note the 236th lowest position of 414. To filter by fuel, space and size, use the water heater selector.

Running cost is not stated here because it depends on the state average residential gas price where the reader lives. The 264 therms of natural gas applies at the high draw pattern only, so any cost built on it carries the same condition. Enter a ZIP in the cost calculator to multiply that figure by the gas price that applies to you. The modeled installed-cost range appears in its own block on this page with its source and date, and it is a modeled range, not a quote. Measured gas use in a given home is not available in the registry. To compare with another unit of the same class, find a same-class replacement by model number.
