KWICKSHOT TEF055V240

This site computes the 615 kWh figure. The registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, together with a fixed daily draw. That draw is the DOE test's daily hot-water draw for the very small draw pattern. This model's UEF is 0.96, from DOE CCD data retrieved 2026-09-19. Its class is the 271 models registered as an electric tankless unit at the very small draw pattern. Within that class, it ranks 77th lowest in energy use of 271. That places it in the second-lowest quarter of its class, and its 0 kWh gap puts it level with the median. The steps behind the figure are set out in how the annual cost is calculated.

The very small draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. This model's maximum flow rate in gallons per minute is 0.6, the flow figure the registry lists for it. The 615 kWh figure holds only at the federal test's daily draw for this pattern. A household that uses more hot water each day than the test assumes will use more energy than 615 kWh. The data does not say how much more. A home that needs more than 0.6 at once falls outside what this listing describes. To compare other fuels or sizes, use the selector by fuel, space and size. To stay within this class, find a same-class replacement by model number.

This text does not give a running cost. The cost depends on your own utility's electricity tariff, and this text does not know that rate. The page calculates it from your ZIP by applying your rate to 615 kWh a year at the very small draw pattern. This model sits 0 kWh from the class median of 615 kWh. At any given rate, its calculated cost therefore matches that of a median unit in its class. You can see the figure for your address in the cost calculator on your own ZIP. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
