STATE UPVA-55E 1**
0.92 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 STATE UPVA-55E 1**, it uses 642 kWh of electricity a year at the federal test's daily hot-water draw. That figure applies to the very small draw pattern, the standard daily hot-water usage DOE tests against. It sits 27 kWh above its class median of 615 kWh, ranking 249th lowest energy use of 271.
Energy use per year
642 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 249 of 271, lowest energy first.
Solid line: this model (642 kWh). Dashed line: the class median.

The 642 kWh figure is calculated by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the daily hot-water draw that the DOE test sets for the very small draw pattern. The figure holds only at that test draw. It does not cover any other daily draw, and your household's actual use is not available here. The source is the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The comparison class is the 271 models registered as an electric tankless unit at the very small draw pattern. That class has a median of 615 kWh, and this model sits 27 kWh above it. This places it in the highest quarter of its class for energy use. The steps are set out 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. This model's maximum flow rate in gallons per minute is 0.5. A plumber or seller checking a listing can match the model number UPVA-55E 1**, the 0.92 UEF and the 0.5 flow rate against the registry entry. A reader who needs more hot water than this draw pattern describes is outside the class this figure was tested in. For that case, the selector by fuel, space and size filters by other classes. Within this class, models ranked ahead of its 249th place use less energy at the same test draw. The same-class replacement search by model number lists those models.
The running cost is not stated in this text because it depends on your own utility's electricity tariff. The page calculates it from your ZIP by applying your rate to the 642 kWh figure at the very small draw pattern. The fuel is electricity, so the cost is the annual kWh multiplied by your rate. For the same reason, the 27 kWh gap to the 615 kWh class median shows up in the cost at any single rate. At the test draw, this model costs more to run than the median model in its class. You can see the result for your rate in the cost calculator on your own ZIP. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote.
