Rheem RTGH-95DVLN-3
0.93 UEF DOE CCD · 2026-09-19Grade C: 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).
If you are checking the Rheem RTGH-95DVLN-3, this gas tankless unit uses 182 therms of natural gas a year. That figure belongs to the high draw pattern, the standard daily hot-water usage DOE tests against. It is 0 therms from its class median of 182 therms, so it is equal to the median.
Energy use per year
182 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 equal to the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 183 of 397, lowest energy first.
Solid line: this model (182 therms). Dashed line: the class median.

This site computed the 182 therms figure. The registry did not publish it. The figure combines the registry'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. For this model the UEF is 0.93, and the source is the DOE CCD, retrieved 2026-09-19. The figure holds only at that federal test draw. If your household draws more or less hot water than the test day, its gas use will differ. A figure for your own household's use is not available here. The steps behind the number are set out in how the annual cost is calculated. If you are a plumber or seller checking a quote, compare 182 therms only with figures for other units at the same draw pattern.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model is compared with the 397 models registered as a gas tankless unit at that draw pattern. Among them it ranks 183rd lowest in energy use. That places it in the second-lowest quarter of its class. The summary above gives its position against the class median. The registry also lists a maximum flow rate in gallons per minute of 5.5. For a smaller household, 182 therms does not describe expected use, because the test assumes the larger daily draw. A figure for a lower draw pattern is not available on this page. To check other models in the same class, look up a same-class replacement by model number.
The text on this page does not state a running cost. The cost of 182 therms of natural gas a year depends on your state's average residential gas price. For that reason, the page computes the cost from your ZIP instead of giving a single figure. Use the cost calculator for your own ZIP to see what 182 therms costs at your rate for this model's UEF of 0.93. A cost at a rate other than your state average is not available here. The installed price has its own block on this page, with its source and date. That block gives a modeled installed-cost range, not a quote. It is separate from the yearly gas figure.
