STATE UPVA-55Y 1**
0.93 UEF DOE CCD · 2026-09-19Grade F: 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 verifying the STATE UPVA-55Y 1**, it uses 635 kWh of electricity a year at the federal test's daily hot-water draw. That figure belongs to the very small draw pattern, the standard daily hot-water usage DOE tests against. It sits 20 kWh above the 615 kWh median for electric tankless units at this draw pattern.
Energy use per year
635 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 218 of 271, lowest energy first.
Solid line: this model (635 kWh). Dashed line: the class median.

This site computes the 635 kWh figure; the registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for this draw pattern. For this model the UEF is 0.93. The result holds only at that test draw. A household that draws more or less hot water will use a different amount, and that amount is not available in the data. There are 271 models registered as an electric tankless unit at the very small draw pattern. This one ranks 218th lowest in energy use among them, which puts it in the highest quarter of its class for energy use. The source is DOE CCD, retrieved 2026-09-19. The page on how the annual energy and cost figures are calculated sets out each step.
The very small draw pattern covers small units: 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 reader who is checking this unit for a sink or a small bathroom is using the class it was tested in. The 218th of 271 ranking applies only within that class. It says nothing about how the unit compares with tank heaters or with electric tankless units tested at other draw patterns. For those uses, the data gives no energy value for this model, so any figure outside this draw pattern is unknown here. To compare other classes, use the water heater selector by fuel, space and size.
This text gives no running cost. The cost depends on your own utility's electricity tariff, so the page works it out from your ZIP. The input is the 635 kWh a year at the test draw, and you supply the rate. The cost calculator for your own ZIP applies that tariff. Compared with the class median, this model uses 20 kWh more electricity a year at the test draw. The cost of that difference depends on the same local rate. If you are checking a like-for-like swap, you can find a same-class replacement by model number starting from UPVA-55Y 1**. The installed-cost range on this page is a modeled figure with its own source and date, not a quote.
