Aquapower Mini-E 2.5-1

This site calculated the 609 kWh figure; the registry does not list it. It combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the very small draw pattern. This model's registered UEF is 0.97, taken from DOE CCD data retrieved 2026-09-19. Because the figure assumes the federal test's draw, it describes a standard test day, not any particular home. A household drawing more or less hot water than the test would use more or less electricity. Among the 271 models registered as an electric tankless unit at this draw pattern, the median is 615 kWh. This model's figure is 6 kWh below that median. The steps behind the calculation are set out in how the annual energy and cost figures are calculated.

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 kind of use. The unit's registered maximum flow rate in gallons per minute is 0.2, the highest flow it is rated to deliver. By energy use it ranks 37th lowest of 271 in its class, which places it in the lowest quarter. That ranking compares it only with other electric tankless units at the very small draw pattern. It says nothing about units tested at other draw patterns, which are not part of this comparison. A plumber or homeowner needing a like-for-like swap can look up a same-class replacement by model number. Anyone whose hot-water needs go beyond this draw pattern can compare water heaters by fuel, space and size.

This text does not state a running cost for the Aquapower Mini-E 2.5-1. The cost depends on the reader's own utility electricity tariff, which differs from one location to another. The page therefore computes it from your ZIP, applying your local rate to the 609 kWh figure. The same condition holds: the result assumes the federal test's daily draw at the very small draw pattern. To see the figure for a specific address, use the running-cost calculator for your own ZIP. The gap of 6 kWh from the class median is converted at that same local rate. The installed price appears in its own block as a modeled installed-cost range with its source and date, not a quote. A seller or plumber verifying a figure should check it against those blocks rather than this text.
