EEMAX SPEX75T

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.97 for this EEMAX SPEX75T. The registry does not state the annual figure. This site computed 609 kWh from that UEF and the DOE test's daily hot-water draw for the very small draw pattern, using DOE CCD data retrieved 2026-09-19. Among the 271 models registered as an electric tankless unit at this draw pattern, it ranks 37th lowest for energy use, which puts it in the lowest quarter of its class. It sits 6 kWh below the class median of 615 kWh. The data does not show how the models around the median are spaced. The calculation method describes how the annual figure is derived.

The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The 609 kWh figure applies only to that pattern. The registry lists the maximum flow rate in gallons per minute as 0.7. The figure fits a reader verifying a unit for one small fixture of the kind the pattern describes. It does not describe a unit serving several fixtures at once, and annual energy for other draw patterns is not available for this model on this page. The registry data also does not say whether 0.7 gallons per minute is enough for any particular fixture. To compare units by fuel, space and size, use the water heater selector.

Running cost is not stated in the text, because it depends on the electricity tariff the reader pays. The 609 kWh figure is electricity use at the very small draw pattern. Multiplying it by the reader's own rate gives the yearly cost at that draw. The cost calculator does this from the reader's ZIP. The 6 kWh difference from the class median of 615 kWh is an energy difference only, and its effect on cost depends on that rate, which is not available here. The modeled installed-cost range appears in its own block with its source and date, and the text does not repeat it.
