BRADFORD WHITE RG2F50S*N

The figure of 249 therms was computed by this site, not by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.68 for this model. It also uses the DOE test's daily hot-water draw 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, this unit ranks 164th lowest in energy use. That places it in the second-lowest quarter of its class. The comparison covers only that class, so it does not apply to other fuels or draw patterns.

The high draw pattern describes a larger household, or one where showers and laundry overlap. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 76 gallons. The rated volume is 48 gallons. Both figures come from the registry. A household with lighter or heavier real use will see a different yearly total than 249 therms. The registry does not show actual household demand, so this page cannot say whether the rating fits a given home. To compare tanks by fuel, space and size, use the water heater selector.

The running cost is not stated in the text. It depends on the state average residential gas price, which differs by state. To see the cost of 249 therms of natural gas, enter your ZIP in the cost calculator. The method page explains how the annual cost is calculated. This unit sits 11 therms below the class median of 260 therms. At the same gas price and the high draw pattern, it costs less to run than the median model. The modeled installed-cost range is in its own block on this page, with its source and date, as a modeled range, not a quote.
