RHEEM/ECOSENSE RTG-95DVLN-1

This site calculates the 206 therms figure; the registry does not state it. It combines the unit'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. The registered UEF is 0.82. The source data is the DOE CCD, retrieved 2026-09-19. Within the class of 397 models, this unit ranks 229th for lowest energy use. That places it in the second-highest quarter of its class for energy use. Every model in the class is compared at the same daily draw, so the rank compares like with like. The page on how this site calculates annual energy and cost sets out each step.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The 206 therms figure describes that level of use. The unit's registered maximum flow rate in gallons per minute is 5. A plumber checking fixtures that run at the same time can compare their combined flow with that 5 limit. For a smaller household, the 206 therms figure does not apply directly, because the test draw is set for the high pattern. A figure for lower daily use is not available on this page. To see gas tankless models at this draw pattern at or below the 182 therms median, use the same-class replacement search by model number.

Running cost is not stated in this text. It depends on your state's average residential gas price, so the page calculates it from your ZIP. That rate is applied to the 206 therms a year at the high draw pattern. The 24 therms gap to the class median would be priced at the same local rate. The running cost calculator for your own ZIP gives that result. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. Neither figure covers a household that draws more or less hot water than the federal test assumes. That level of use is not available here.
