BRADFORD WHITE CTEH010********

The figure of 649 kWh is not read directly from the registry. 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 at the very small draw pattern. It also used the daily hot-water draw that the DOE test assigns to that pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The class median is 615 kWh across the 271 models registered as an electric tankless unit at this draw pattern. This model sits 34 kWh above that median and ranks 265th lowest in energy use, which places it in the highest quarter of its class for energy use.

The figure applies only to the very small draw pattern, meaning small units such as a single bathroom or a point-of-use heater under a sink. The registry lists a maximum flow rate in gallons per minute of 1 for this model. A reader with that kind of use can compare the 649 kWh with the class median of 615 kWh directly. A reader whose hot-water demand is larger should not treat this figure as describing their use, because it was computed only at the very small draw pattern. Energy figures for other draw patterns are not available on this page, and the page does not estimate them.

The running cost is not written here because it depends on your own utility electricity tariff. To check it, multiply the 649 kWh by your rate per kilowatt-hour, or use the cost calculator, which takes your ZIP. The methodology page explains how the annual cost is calculated. Because this model is 34 kWh above the class median of 615 kWh, its cost at any single rate is higher than that of a median model at the same draw pattern. To compare, find a same-class replacement by model number, or use the water heater selector to filter by fuel, space and size. The modeled installed-cost range is shown in its own block on the page, with its source and date.
