E

Grade E: 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).

For the EEMAX SPEX3012, the federal test gives 615 kWh of electricity a year. That figure belongs to the very small draw pattern, the standard daily hot-water usage DOE tests against. It equals the class median of 615 kWh, a difference of 0 kWh. Its energy use ranks 77th lowest of 271 models.


Energy use per year

615 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 equal to the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 77 of 271, lowest energy first.

This model: 615 kWh

Solid line: this model (615 kWh). Dashed line: the class median.

What these figures mean

The figure of 615 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. This model's UEF is 0.96, and its maximum flow rate in gallons per minute is 0.3. The figure applies only to the very small draw pattern and to electricity. It is a calculation at the test's draw, not a reading from a particular home. The source is DOE CCD, retrieved 2026-09-19. The method behind the annual figure is documented on the methodology page.

The class holds 271 models registered as an electric tankless unit at the very small draw pattern. This model's energy use of 615 kWh equals the class median of 615 kWh. The difference from the median is 0 kWh. It ranks 77th lowest of 271, which places it in the second-lowest quarter of its class for energy use. The very small draw pattern means small units, such as a single bathroom or a point-of-use heater under a sink. For those uses, the figure of 615 kWh is the one to compare against other models in the class. The data gives no figure for a larger draw pattern.

The running cost is not in this text, because it depends on your own utility electricity tariff. Use the cost calculator for your ZIP to see it. The calculation starts from the annual energy of 615 kWh at the very small draw pattern. A different draw pattern would change that energy figure, and this page does not estimate one. The installed price range is in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote. To compare models in the same class as SPEX3012, find a same-class replacement by model number. Any comparison should use the same draw pattern, since 615 kWh applies only to the very small one.
