BRADFORD WHITE RG2D50S*N

The annual figure is computed by this site, not by the registry. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.68 for this model. The site combines that UEF with the DOE test's daily hot-water draw for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. The result, 249 therms of natural gas a year, applies only to the high draw pattern at the federal test's draw. It is not a measurement of any installed unit. The steps are set out in how the annual cost is calculated.

Against its class, this model has the 164th lowest energy use of 414. That is in the second-lowest quarter of its class for energy use. Its 249 therms sits 11 therms below the class median of 260 therms. 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 81 gallons. The rated volume is 47 gallons. The data does not say whether these figures match your peak demand. A household with a different real draw should not read 249 therms as its own use. The selector by fuel, space and size lets you compare other fuels and sizes.

The running cost is not written in the text. It depends on your state's average residential gas price, which this page does not know. The cost calculator on your own ZIP applies that price to 249 therms. The result holds only at the high draw pattern and the federal test's draw. The modeled installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote, and it is not repeated here. To compare a same-class unit, search by model number with the same-class replacement finder, starting from RG2D50S*N. The site cannot state a cost for a household whose gas rate is unknown.
