FRIEDRICH RTGH-95DVLN-3

The 182 therms figure is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the test's daily draw. This unit's UEF is 0.93. The source data is DOE CCD, retrieved 2026-09-19. The figure holds only for the high draw pattern at the federal test's draw. A home with different hot-water use would use a different amount of gas. The registry lists its maximum flow rate in gallons per minute as 5.5, which is a separate rating from energy use. The steps are described in how the annual cost is calculated.

Among the 397 models registered as a gas tankless unit at the high draw pattern, this one has the 183rd lowest energy use. That places it in the second-lowest quarter of its class. Its 182 therms is equal to the class median of 182 therms, so the difference is 0 therms. The unit suits a larger household, or one where showers and laundry overlap, because that is the use the high draw pattern represents. It is a weaker match for a small household, whose use falls under a lower draw pattern. Those homes should read the figure for their own pattern. To compare other fuels, sizes or spaces, use the selector by fuel, space and size.

The running cost of the RTGH-95DVLN-3 depends on your state's average residential gas price, so this text states no cost. To estimate it, multiply 182 therms by your gas price per therm. That gives the yearly cost at the federal test's draw, not at your home's own use. The cost calculator on your own ZIP does this step from your state's price. The installed price range is shown in its own block, with its source and date. It is a modeled installed-cost range, not a quote. The registry gives no measured gas use for a real household, so that value is not available. For a unit in the same class, use the same-class replacement finder by model number.
