Ruud RTGH-C95DVLN

This site calculated the 182 therms figure; the registry does not list it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used. It applies that ratio to the DOE test's daily hot-water draw for the high draw pattern. This unit has a UEF of 0.93, from DOE CCD data retrieved 2026-09-19. At that draw, it is 0 therms away from the class median. It ranks 183rd lowest energy use of 397. A plumber or seller checking a listing can compare these values with the registry entry for RTGH-C95DVLN. The steps behind the calculation are explained in how the annual energy and cost figures are calculated.

The high draw pattern represents a larger household, or one where showers and laundry overlap. The 182 therms value applies only at the federal test's daily draw for that pattern. The data here does not give energy use for homes that draw more or less hot water each day. That value is not available on this page. The registered maximum flow rate in gallons per minute is 5.7. The data does not show how that flow is shared among fixtures running at the same time. To compare this unit with water heaters that use other fuels, fit other spaces or come in other sizes, use the water heater selector by fuel, space and size.

This text does not state a running cost because it depends on your state's average residential gas price. The page calculates it from your ZIP code. It uses the 182 therms of natural gas per year at the high draw pattern. Enter your ZIP in the running cost calculator for your own ZIP to see that figure. The installed price range appears in its own block on this page, with its source and date. That range is modeled, not a quote. To find a unit in the same class as RTGH-C95DVLN, the same-class replacement search by model number covers the 397 gas tankless models registered at the high draw pattern.
