0.91 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 271 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tankless unit, very small draw pattern (small units - a single bathroom, or a point-of-use heater under a sink).
If you are checking the LAARS LCTEH010********, this site computes 649 kWh of electricity a year for its very small draw pattern, the standard daily hot-water usage DOE tests against. That is 34 kWh above the class median of 615 kWh among 271 electric tankless models.
Energy use per year
649 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is above the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 265 of 271, lowest energy first.
Solid line: this model (649 kWh). Dashed line: the class median.

The figure is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.91 for this model, and from 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 result, 649 kWh, is in kilowatt-hours of electricity and holds only at that test draw. A household that draws more or less hot water will use a different amount. The calculation is described on the methodology page for water heater costs.
Ranked by energy use at the very small draw pattern, this model is 265th lowest of 271, which places it in the highest quarter of its class for energy use. Its 649 kWh is 34 kWh above the class median of 615 kWh. The rating applies to small units: a single bathroom, or a point-of-use heater under a sink. The maximum flow rate in gallons per minute is 1 for this model. For a reader whose load matches that small draw, the class comparison shows that most of the 271 models use less energy. To compare against other units of the same class, use the same-class replacement search by model number.
The running cost is not stated here, because it depends on your own utility electricity rate and the registry data does not include one. The cost calculator for your ZIP applies your local tariff to the 649 kWh figure. That figure is a test-condition value, not a measurement of this unit in a home, so actual use will differ with the amount of hot water drawn. Measured household use for this model is not available in the data used here. The modeled installed-cost range appears in its own block on this page, with its source and date.
