BRADFORD WHITE RTG-K-160N1

The figure of 178 therms is this site's own calculation, not a registry entry. It combines the registry's 0.95 UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test assigns to the high draw pattern. The registry data was retrieved from DOE CCD on 2026-09-19. Among the 397 gas tankless models registered at this draw pattern, this unit has the 45th lowest energy use, which places it in the lowest quarter of its class. The class median is 182 therms, so the unit sits 4 therms below it. The calculation method explains how the annual figure is derived.

The unit's maximum flow rate in gallons per minute is listed as 4.6. The registry gives that value alone; it does not show how many fixtures the unit can serve at once at a given incoming water temperature, and that information is not available here. The 178 therms figure applies to a larger household, or one where showers and laundry overlap, because that is what the high draw pattern represents. The comparison is useful for a reader checking a unit for that use against the 397 models in its class. It does not describe a household whose daily hot-water use differs from the federal test draw. For a search by fuel, space and size, use the water heater selector.

The running cost is not stated in this text because it depends on the average residential gas price in your state. The cost calculator applies that price, taken from your ZIP, to the 178 therms shown here. The unit sits 4 therms below the class median of 182 therms, so its cost gap from a median unit follows from that difference and your own rate; this page states no amount for it. The modeled installed-cost range appears in its own block with its source and date, and this text does not restate it. To look for a same-class model, use the replacement search by model number with RTG-K-160N1.
