KWICKSHOT TET095V240

The figure of 603 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.98 with the daily hot-water draw that the DOE test assigns to the very small draw pattern. It applies only to that draw pattern and to electricity as the fuel. The underlying registry data come from the DOE CCD, retrieved 2026-09-19. A household that draws more or less hot water than the test assumes will use a different amount of energy, and this page does not estimate that difference. The steps behind the calculation are set out in how the annual cost is calculated.

The comparison group is the 271 models registered as an electric tankless unit at the very small draw pattern. Their median is 615 kWh, and this model sits 12 kWh below it. Its rank of 10th lowest places it in the lowest quarter of its class for energy use. That position holds only at this draw pattern and does not describe other draw patterns or other fuels. The registry lists a maximum flow rate in gallons per minute of 0.9. The pattern is meant for small units, such as a single bathroom or a point-of-use heater under a sink. Any demand above 0.9 gallons per minute at one time falls outside this rating, and the water heater selector filters by fuel, space and size.

The running cost is not stated in this text because it depends on your own utility electricity tariff. The cost calculator applies the rate for your ZIP to the 603 kWh shown here, and the result is a calculation from the federal test's draw, not a measurement of your household. The installed-price range appears in its own block with its source and date, as a modeled range and not a quote. If you need a unit of the same class, you can find a same-class replacement by model number. To see the cost for your rate, use the cost calculator on your own ZIP.
