Kiturami KGWH-190JFN
0.96 UEF DOE CCD · 2026-09-19Grade A: 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 the Kiturami KGWH-190JFN against its registry entry? This gas tankless unit uses 176 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 6 therms below the class median of 182 therms among 397 registered models.
Energy use per year
176 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 below the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 12 of 397, lowest energy first.
Solid line: this model (176 therms). Dashed line: the class median.

UEF 0.96 · Grade A Price it on your ZIP
The registry lists this model at a UEF, the ratio of hot water delivered to energy used, of 0.96. This site combines that UEF with the daily hot-water draw the DOE test assigns to the high draw pattern, which gives 176 therms of natural gas a year. The registry itself does not publish that annual figure. The underlying data was retrieved from DOE CCD on 2026-09-19. Ranked by energy use, the model is 12th lowest of 397 in its class, which places it in the lowest quarter. Its distance from the class median of 182 therms is 6 therms. The how the annual cost is calculated page describes the method.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. The 176 therms figure applies only to that pattern. A household with lower hot-water use would need the figure for a different draw pattern, and that figure is not available on this page. The unit's maximum flow rate in gallons per minute is 5.8. This page does not convert that flow rate into a number of outlets, so it draws no conclusion on simultaneous use. To compare other fuels, spaces or sizes, the water heater selector filters by those inputs.
Running cost is not written here because it depends on the state average residential gas price, which differs between readers. Enter your ZIP in the cost calculator to apply your own rate to 176 therms. The result is modeled at the federal test's draw, not a bill, and real use will differ with the household's actual hot-water demand. The gap of 6 therms from the class median of 182 therms changes cost only by that amount of gas at your rate. The installed price range is shown in its own block with its source and date.
