Rheem RTG-95XLN-3
0.82 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 397 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tankless unit, high draw pattern (a larger household, or one where showers and laundry overlap).
Checking a quote or spec sheet for the Rheem RTG-95XLN-3, a gas tankless unit? It uses 206 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 24 therms above the 182 therms median of the 397 gas tankless models registered at the same pattern.
Energy use per year
206 therms a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.
That is above the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 229 of 397, lowest energy first.
Solid line: this model (206 therms). Dashed line: the class median.

This site calculates the 206 therms figure; the registry does not publish it. The calculation starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.82 for this model. It then applies that value to the DOE test's daily hot-water draw for the high draw pattern. The UEF comes from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The 206 therms figure applies only at that test draw. A household that uses more hot water than the test assumes will use more gas, and one that uses less will use less. Among the 397 models in its class, this unit ranks 229th lowest in energy use. That puts it in the second-highest quarter of its class for energy use. You can check each step on the page explaining how the annual cost is calculated.
The high draw pattern describes a larger household, or one where showers and laundry overlap. For that kind of household, the 206 therms figure is the right one to compare. The registry lists this unit's maximum flow rate in gallons per minute as 4.8. For a smaller household with lighter hot-water use, the test figure does not describe expected use. This page has no energy figure for a lower draw pattern, so that value is not available here. The 24 therms gap puts this model above the 182 therms class median for gas use at the same test draw. To compare it with other models in the same class, use find a same-class replacement by model number.
The running cost does not appear in this text because it depends on your own gas rate. The page takes your state's average residential natural gas price from your ZIP and applies it to 206 therms a year at the high draw pattern. The 24 therms difference from the class median becomes a cost difference at that same rate. Both results appear in the cost calculator on your own ZIP, not in this paragraph. Without your ZIP, the yearly cost for this unit is unknown. 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.
