Ruud RTG-95DVLN-3

The yearly figure of 206 therms at the high draw pattern is computed by this site, not published by the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used. For this model, the UEF is 0.82 at the high draw pattern. The calculation then applies the DOE test's daily hot-water draw for that pattern. The registry data come from the DOE Compliance Certification Database, retrieved 2026-09-19. The method is set out in how the annual cost is calculated. Your own household may use more or less hot water than the test assumes. In that case, your yearly use will differ from the 206 therms at the high draw pattern. How far it differs is not available from the registry data.

The high draw pattern describes a larger household, or one where showers and laundry overlap. Among the 397 gas tankless models registered at that pattern, this unit ranks 229th for lowest energy use. That places it in the second-highest quarter of its class for energy use. Because every model in the class is rated at the same draw, the yearly 24 therms gap above the median compares like with like. Its maximum flow rate in gallons per minute is 4.8, as listed in the registry. The temperature rise behind that rating is not available in this data. To compare other units, use the selector by fuel, space and size.

A smaller household may not match the high draw pattern that the 206 therms figure assumes. For such a household, a figure at a lower draw pattern for this model is not available in this data. The running cost is not stated here, because it depends on your state's average residential gas price. The page computes it from your ZIP, using 206 therms of natural gas a year at the high draw pattern. You can rerun that figure in the cost calculator for your own ZIP. The installed-price range on this page is a modeled installed-cost range, not a quote. Its source and date appear in its own block. To match a unit in the same class, search for a same-class replacement by model number.
