GE GE11SNHPDG01

The figure of 649 kWh combines two inputs: the registry's UEF, the ratio of hot water delivered to energy used, which is 0.91, and the federal test's daily hot-water draw for the very small draw pattern. The registry does not list this annual figure, so this site calculated it. The source data is DOE CCD, retrieved 2026-09-19. The registry also lists a maximum flow rate in gallons per minute of 1.1. The gap of 34 kWh from the class median of 615 kWh applies only to the 271 electric tankless models registered at this draw pattern. The steps are set out in how the annual cost is calculated.

The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. If your use matches that description, 649 kWh is the figure to check against. The GE GE11SNHPDG01 ranks 265th lowest in energy use of 271, which puts it in the highest quarter of its class for energy use. Other models at this draw pattern use less electricity under the same test condition. The registry data gives no figure for any other draw pattern for this model, so annual energy at a larger household draw is not available. To compare units in the same class, you can find a same-class replacement by model number.

Running cost is not stated here because it depends on your own utility electricity tariff, and this page assumes none. The 649 kWh figure is the energy at the federal test's daily draw, so your actual use may differ if your hot-water draw differs. Your real draw and your local rate are both unknown to this page. To turn 649 kWh into a yearly cost, use the cost calculator on your own ZIP, which applies the electricity rate for your location. The modeled installed-cost range appears in its own block with its source and date.
