KWICKSHOT TEF030V120

This site computed the 615 kWh figure; the registry does not publish it. The calculation combines the registry's UEF, the ratio of hot water delivered to energy used, which is 0.96 for this model, with the DOE test's daily hot-water draw for the very small draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw, so a household that draws more or less hot water will use a different amount. The registry also lists a maximum flow rate in gallons per minute of 0.3. That value describes the unit's flow limit and is not an input to the annual energy figure.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this model has the 77th lowest energy use. That places it in the second-lowest quarter of its class. Its 615 kWh equals the class median of 615 kWh, so the difference is 0 kWh. The comparison covers energy use at the test draw only; it does not compare flow, price or any other attribute. The very small draw pattern describes small units, such as a single bathroom or a point-of-use heater under a sink. Larger loads fall outside this pattern, and this figure does not describe them. To see other units in the same class, use the same-class replacement search by model number.

The registry data does not state a running cost, because it depends on your own utility electricity rate. The 615 kWh figure is the quantity to multiply by that rate, and it applies only at the test draw, not at your measured usage. The cost calculator for your own ZIP does this calculation, and how the annual cost is calculated sets out the method. A modeled installed-cost range appears in its own block on this page with its source and date. It is a modeled range, not a quote, and it is not repeated here. If your household falls outside the very small draw pattern, the water heater selector by fuel, space and size covers other cases.
