TURBRO WH-65K

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.82 for TURBRO WH-65K. This site, not the registry, converts that UEF into 93 therms of natural gas a year by applying the DOE test's daily hot-water draw for the low draw pattern. The figure was retrieved on 2026-09-19. Among the 10 models registered as a gas tankless unit at the low draw pattern, this unit ranks 4th lowest for energy use. That places it in the second-lowest quarter of its class. Its difference from the class median of 93 therms is 0 therms, so it uses the same energy as the median model. The calculation is described on the methodology page.

The low draw pattern describes a one- or two-person household, so the figure of 93 therms applies only to that level of hot-water use. The registry also lists a maximum flow rate in gallons per minute of 2.4 for this unit. That rating is a separate figure from the annual energy and does not change it. A household with heavier daily use than the federal test assumes would not match the 93 therms shown here. Energy figures for other draw patterns are not available on this page. To compare units by fuel, space and size, the water heater selector filters on those three inputs.

The running cost is not written in the text, because it depends on the state average residential gas price where the reader lives. The cost is 93 therms multiplied by that price, and the page computes it from the ZIP you enter in the cost calculator. No price is estimated here. The annual figure assumes the federal test's daily draw for the low draw pattern, so gas use in a home can differ, and the registry does not measure it. The modeled installed-cost range appears in its own block with its source and date, and it is not repeated here. To look for a same-class unit, the replacement finder searches by model number, for example WH-65K.
