Ruud RTGH-95DVLN-3

The 182 therms figure is calculated by this site. The registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. For this unit the UEF is 0.93, taken from the DOE Compliance Certification Database (CCD) and retrieved 2026-09-19. The result applies only at the federal test's daily draw. This figure does not give the gas use of a home that draws more or less hot water than the test assumes. The conversion steps are set out in how the annual energy and cost figures are calculated.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The unit's maximum flow rate in gallons per minute is 5.5, as listed in the registry. It ranks 183rd lowest for energy use among the 397 models in its class. That rank places it in the second-lowest quarter of the class. Its difference from the class median is 0 therms, so its annual use sits at the median. It does not sit below the median. To check other registered units in the same class, use the same-class replacement search by model number.

The 182 therms figure does not describe a smaller household with a lower daily draw. The data does not include an energy figure for this model at any other draw pattern. The figure is stated in natural gas, the fuel listed for this unit. The running cost is not given in this text because it depends on your state's average residential gas price. The page calculates it from your ZIP by applying that price to 182 therms a year. You can run the same calculation in the water heater cost calculator for your ZIP. The installed price range appears in its own block, with its own source and date. It is a modeled range, not a quote.
