EEMAX SPEX95T

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.98 for the EEMAX SPEX95T. This site did not copy the annual energy figure from the registry. It computed 603 kWh of electricity from that UEF and the daily hot-water draw in the DOE test for the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. Against the 271 electric tankless models registered at the same draw pattern, the median is 615 kWh, so this unit sits 12 kWh below it. Its rank of 10th lowest puts it in the lowest quarter of its class for energy use. The registry also lists a maximum flow rate in gallons per minute of 0.9.

The very small draw pattern describes small units, such as a single bathroom or a point-of-use heater under a sink. The 603 kWh figure fits that use and no other, because the test draw is fixed for the pattern. If the real hot-water use in a home is larger than the test draw, the figure no longer describes that home, and this page has no data on by how much. The maximum flow rate of 0.9 is a registry rating; it does not show how many fixtures the unit can serve at once. For a different fuel, space or size, the water heater selector filters by those inputs. To find a same-class replacement for this unit, the replacement finder starts from a model number.

The running cost is not printed here because it depends on your own utility electricity tariff. It is the annual energy of 603 kWh priced at your rate, and the registry does not hold that rate. The cost calculator takes your ZIP and applies the local rate to this figure. The steps behind that calculation are in the methodology. The margin of 12 kWh below the class median of 615 kWh is a difference in energy, not in cost; whether it changes a bill depends on the same rate. The modeled installed-cost range appears in its own block with its source and date, as an estimate and not a quote. It is not repeated in this text.
