KWICKSHOT TEF041V277

The registry lists this unit's UEF, the ratio of hot water delivered to energy used, as 0.96. This site computed the annual figure of 615 kWh from that UEF and the daily hot-water draw in the DOE test for the very small draw pattern; the registry does not publish the annual figure itself. The source is DOE CCD, retrieved 2026-09-19. The class median is 615 kWh, so this model sits 0 kWh from it. Its rank is 77th lowest energy use of 271 models, which places it in the second-lowest quarter of its class. The calculation is described on the methodology page.

The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The 615 kWh figure applies only at that draw. A household with a larger daily hot-water demand is not represented by it, and the data here gives no energy figure for any other draw pattern. The listed maximum flow rate in gallons per minute is 0.4. That is the registry's listed value for this model, and it is separate from annual energy. For a different fuel, space or size, the water heater selector filters by those inputs.

The running cost is not stated in this text because it depends on your own utility electricity tariff. Multiply 615 kWh by your rate per kilowatt-hour to check it, or enter your ZIP in the cost calculator, which does the calculation for you. Because this model equals the class median of 615 kWh, its running cost at any given rate matches that of a model at the median for the same draw pattern. The figure is a test-based calculation, not a measurement in your home. The modeled installed-cost range appears in its own block on the page, with its source and date.
