Rheem RTG-95DVLN-3

This site calculates the 206 therms figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the high draw pattern. This model's registered UEF is 0.82. The registry data were retrieved from DOE's Compliance Certification Database (CCD) on 2026-09-19. The figure holds only at that federal test draw. A home that uses more or less hot water each day will use a different amount of gas, and this page has no figure for those other levels. The steps behind the number are set out in how the annual energy and cost figures are calculated.

Among the 397 gas tankless models registered at the high draw pattern, this unit ranks 229th for lowest energy use. That places it in the second-highest quarter of its class for energy use at the same test draw. The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry also lists this model's maximum flow rate in gallons per minute as 4.8. Neither the 206 therms figure nor the rank was measured for a household whose hot-water use fits a smaller draw pattern. To check other units against the same class, use the same-class replacement search by model number.

The text of this page does not give a running cost. That cost depends on your state's average residential natural gas price, so the page calculates it from your ZIP code. At the federal test's daily draw, this model uses 24 therms per year more than its class median. The cost of that gap is known only after your rate is applied. You can work out the figure on your own rate in the water heater running cost calculator for your ZIP. The installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote from an installer.
