OPTIMIZED ENERGY USAGE
The table below shows the flow rate in gallons per minute (gpm), related to deliverable output water temperature (°F)
and optimized electrical energy usage (kW). The table shows you the results that can be achieved by varying the water
flow and temperature. The optimum operational capability of the unit is reached at full-rated power.
