Ruud RTG-95DVLN-1

The 206 therms figure is calculated by this site. The registry does not publish it. It 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 unit the UEF is 0.82. The inputs come from DOE CCD data retrieved 2026-09-19. The figure applies at that test draw only, not to any particular household's actual use. A household that draws a different amount of hot water each day is outside what this figure describes. The steps from this energy figure to a yearly cost are explained in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For the RTG-95DVLN-1, the registry lists a maximum flow rate in gallons per minute of 5. Among the 397 gas tankless models tested at the high draw pattern, this unit ranks 229th lowest in energy use. That puts it in the second-highest quarter of its class for energy use, above the class median given at the top of this page. A reader who wants a unit below that median will not find it in this model. To check other models in the same class, use find a same-class replacement by model number.

The text does not give a running cost for the RTG-95DVLN-1. The cost of 206 therms of natural gas a year depends on the average residential gas price in the reader's state. For that reason, the page calculates the cost from the reader's ZIP. This text does not state or estimate a yearly cost. The cost calculator on your own ZIP applies your state's rate to this unit's annual energy use at the high draw pattern. The same calculation can be run for any model in the class, including models near the 182 therms median. The installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote.
