BRADFORD WHITE RG240S*N

The registry lists this model's UEF, the ratio of hot water delivered to energy used, as 0.58. The annual energy figure is not a registry value. This site computed 191 therms of natural gas from that UEF and the daily hot-water draw in the DOE test for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 288 models registered as a gas tank at this draw pattern, the unit ranks 231st lowest in energy use. That places it in the highest quarter of its class for energy use, with its figure 6 therms above the class median of 185 therms.

The medium draw pattern describes a typical household on a busy morning, so 191 therms applies to that use and to no other. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 69 gallons. The rated volume is 38 gallons. A household whose use resembles the medium pattern can compare 191 therms directly with the class median of 185 therms. A household with heavier or lighter use will see a different yearly figure, and the registry data used here does not provide one for other draw patterns. To narrow options by fuel, space and size, use the water heater selector.

The running cost is not stated here because it depends on your state's average residential gas price. The gap of 6 therms from the class median of 185 therms is a difference in gas use, and its cost depends on the same rate.
