RHEEM/ECOSENSE RTG-95XLN-1

The registry does not print the 209 therms figure. This site computes it from the registry's UEF, the ratio of hot water delivered to energy used. It combines that ratio with the DOE test's daily hot-water draw for the high draw pattern. For this model the listed UEF is 0.81, from DOE CCD data retrieved 2026-09-19. The result holds only at that federal test draw. A household that draws more or less hot water each day will use a different amount of gas, and this page does not have that household's figure. The full method is set out in how the annual cost is calculated. Among the 397 models in its class, this unit ranks 323rd lowest in energy use. That places it in the highest quarter of its class for energy use at the high draw pattern.

The high draw pattern describes a larger household, or one where showers and laundry overlap. That is the use the 209 therms figure models. The registry lists a maximum flow rate in gallons per minute of 4.9 for this unit. Whether that rate covers a given home's fixtures running together depends on their own flow ratings, which are not available here. A household with lighter daily use falls outside the tested pattern, so its gas use cannot be read from this figure. Within the class, the gap to note is 27 therms a year above the 182 therms median, both at the high draw pattern.

This text does not state the running cost. It depends on the reader's state average residential gas price, so the page computes it from the reader's ZIP. That price is applied to the 209 therms this unit uses at the high draw pattern. The 27 therms gap to the class median carries into cost at whatever rate the reader's state has. The cost calculator on your own ZIP shows that result. The installed-cost range appears in its own block on this page, with its source and date. It is a modeled range, not a quote. Neither figure is a measured gas bill from an installed unit.
