Rheem RTG-70DVLN-3

The registry does not publish the 206 therms figure. This site computes it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high pattern. At that draw, a UEF of 0.82 gives 206 therms of natural gas per year. The UEF comes from the DOE CCD, retrieved 2026-09-19. The figure holds only at the test's daily draw. The registry does not report use in any real home, so a figure for your own household is not available. The method is set out on the page on how the annual cost is calculated.

The high draw pattern stands for a larger household, or a home where showers and laundry overlap. For that use, this unit lists a maximum flow rate in gallons per minute of 4. Among the 397 models registered as a gas tankless unit at the high draw pattern, the median is 182 therms a year. At the test's draw, this model uses 24 therms more than that median and ranks 229th lowest energy use of 397. For a smaller household, the high-pattern figure does not describe its use. No figure for another draw pattern is in this data, so that comparison is not available. To check a same-class model by its number, use the tool to find a same-class replacement by model number.

Running cost is not stated in this text because it depends on your state's average residential natural gas price. The page computes it from 206 therms and that price once you enter your ZIP. The result therefore holds only at the high draw pattern and at your state's average rate. The 24 therms gap to the class median carries into cost the same way, scaled by that same price. A negotiated rate or a tiered tariff is not reflected in a state average. You can run the figures in the cost calculator on your own ZIP. The installed price appears in its own block as a modeled range, not a quote, with its own source and date.
