FRIEDRICH RTG-95DVLN-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 gas tankless unit for a larger household? The FRIEDRICH RTG-95DVLN-3 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 class median of 182 therms among 397 models.
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.

The figure of 206 therms is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.82 for this model, and from the DOE test's daily hot-water draw for the high draw pattern. It applies to natural gas only and to that test draw, so a home that uses more or less hot water will land elsewhere. The registry data comes from DOE CCD, retrieved 2026-09-19. The calculation is set out in how the annual cost is calculated.
Ranked by energy use from lowest, this model is 229th of 397. That places it in the second-highest quarter of its class for energy use, with 206 therms against a class median of 182 therms, a difference of 24 therms. The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists the maximum flow rate in gallons per minute as 4.8. Whether that flow covers simultaneous use in a particular home is not established by this page. Anyone whose priority is gas use at or below 182 therms at this draw pattern will find models in the class that meet it. The selector by fuel, space and size and the same-class replacement lookup by model number can narrow those.
Running cost is not stated here because it depends on your state's average residential gas price. Multiply 206 therms by your own rate per therm to get a yearly figure at the test draw. The cost calculator on your own ZIP does this with the state average. The 24 therms gap to the class median scales with the same rate, so it grows or shrinks with the price you pay. Actual use differs from the test draw, and the registry does not record how much hot water your household uses. The modeled installed-cost range appears in its own block on the page, with its source and date, and is not a quote.
