Flow rate shown in GPM based on outlet temperature of 105°F. Inlet temperature varies by region and seasonal changes.
The ECO 18 is a mid-range EcoSmart tankless water heater capable of heating multiple
fixtures simultaneously. In colder areas, with an inlet water temperature around 37°F,
the ECO 18 can heat water for a water-saving shower head. Two showers can be run
at the same time in warmer climates when incoming water temperature is above 67°F.
This model is equipped with patented, self-modulating technology so that it will only
consume the energy necessary for the current demand. Below is a chart showing the
flow rate capacity of each model, measured in gallons per minute for various inlet
water temperatures and calculated for a set output temperature of 105° F.
