LAARS LCTEV005********

The 615 kWh figure 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 0.96 with the DOE test's daily hot-water draw for the very small draw pattern. The fuel is electricity, and the source is the DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw. A household that uses more or less hot water than the test assumes will use a different amount of electricity. The registry also lists a maximum flow rate in gallons per minute of 0.5 for this model.

The comparison group is the 271 models registered as an electric tankless unit at the very small draw pattern. Within that group, this model has the 77th lowest energy use of 271, which 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 data supplied does not explain how tied values are ranked, so that detail is unknown here. The ranking uses energy use alone and says nothing about any other property of the model.

This draw pattern describes small units - a single bathroom, or a point-of-use heater under a sink. The 615 kWh figure suits a reader checking a unit for that kind of use at the test draw. It does not describe a whole-house load, and it does not cover other draw patterns. Running cost is not stated in the text, because it depends on your own utility electricity tariff. Enter your ZIP in the cost calculator to apply your rate, and read how the annual cost is calculated for the method. To look for units in the same class, use find a same-class replacement by model number. The modeled installed-cost range appears in its own block on this page.
