ECOSMART ECO POU 6

The registry does not print the 628 kWh figure. This site computed it from two inputs: the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for this draw pattern. The registry lists a UEF of 0.94 for this model. The source is the DOE CCD, retrieved 2026-09-19. The class is the 271 models registered as an electric tankless unit at this draw pattern. Within it, the ECO POU 6 ranks 188th for lowest energy use. That rank places it in the second-highest quarter of its class for energy use. The figure applies only at the test's daily draw. This page has no figure for a household that draws a different volume of hot water.

The very small draw pattern covers small units that serve a single bathroom, or a point-of-use heater under a sink. For the ECO POU 6, the registry lists a maximum flow rate in gallons per minute of 0.5. A plumber or seller checking a listing can compare that flow rate and the UEF against the unit's label. The 628 kWh figure does not describe demand beyond this pattern's test draw. The registry gives no results for this model at any other draw pattern, so this page cannot say how it would perform in a larger role. To look at registered models in other classes, use the selector by fuel, space and size, which filters by those criteria.

This text does not state a running cost. The cost depends on your own utility's electricity tariff, applied to the 628 kWh used at the test draw. The cost calculator for your own ZIP applies your local rate to that figure. The steps behind that calculation are explained in how the annual cost is calculated. The installed price is shown in its own block on this page, with its source and date. It is a modeled range for installed cost, not a quote. If you are matching a replacement for the ECO POU 6, you can find a same-class replacement by model number among models registered in the same class as this unit.
