STATE UPVA-30K 1**

The 635 kWh figure does not appear in the registry itself. This site calculated it from the registry's UEF, the ratio of hot water delivered to energy used. The other input is the DOE test's daily hot-water draw for the very small draw pattern. This model's UEF is 0.93. The registry values come from the DOE CCD, retrieved 2026-09-19. The result applies only to the federal test's daily draw, not to a measured household. Energy use at any other daily draw is not available in this data. A plumber or seller checking the figure can trace each step in how the annual cost is calculated.

The very small draw pattern covers small units, such as a heater for a single bathroom or a point-of-use heater under a sink. The registry lists a maximum flow rate in gallons per minute of 0.3 for this electric tankless unit. Its class is the 271 models registered as electric tankless units at this draw pattern. Within that class, it ranks 218th lowest in energy use. That puts it in the highest quarter of its class for energy use, 20 kWh above the 615 kWh median. This data does not show how the unit performs at draws larger than the very small pattern. If you want a unit nearer to or below that median, you can find a same-class replacement by model number.

This text does not state a running cost. The cost depends on your own utility's electricity tariff, so the page calculates it from your ZIP. You can repeat that step with the cost calculator on your own ZIP. Tariffs differ between utilities, so the same 635 kWh can produce a different yearly cost in each ZIP. At any single rate, this model's cost gap to a median unit in its class follows from the 20 kWh energy gap. The modeled installed-cost range appears in its own block on this page, with its source and date. That range is a model of installed cost, not a quote, and it is separate from the yearly energy figure.
