BRADFORD WHITE RG2DVMH40T*N

This site calculates the 191 therms figure; the registry does not list it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the daily hot-water draw that the DOE test sets for the medium draw pattern. This model's UEF is 0.58, from DOE CCD data retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water would burn a different amount of gas. The registry does not report how much this model uses in a real home, so that figure is not available. See how the annual cost is calculated for each step of the calculation.

DOE uses the medium draw pattern to represent a typical household on a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons, from a rated volume of 38 gallons. The 191 therms figure is based on this condition. It fits a household whose busy-morning use stays within that rating. It does not fit a household that regularly needs more than 51 gallons in its first hour. Out of 288 models in its class, it ranks 231st for lowest energy use. To compare it with other models in the same class, use find a same-class replacement by model number. The selector by fuel, space and size filters by other conditions.

The running cost is not stated here because it depends on your state's average residential natural gas price. The page calculates it from your ZIP, using the 191 therms figure at the medium draw pattern. Your gas price also determines what the 6 therms gap above the 185 therms class median costs. Any cost difference from a median model therefore depends on your rate, too. The installed-price range appears in its own block with its source and date. It is a modeled range, not a quote.
