Electric tankless water heater for commercial

The Eemax EX200TC S is a single-phase electric tankless water heater rated at 20000 W and 277 V AC. It draws 72 A and delivers hot water at flow rates from 0.7 gpm up to 3 gpm. Adjustable thermostat control allows outlet temperatures between 100 and 180 degrees F for single or multi-fixture applications.

Verify that the installation site provides 277 V AC single-phase power and a 72 A circuit. The cold water inlet requires a 3/4 in connection. Ensure indoor mounting space accommodates the unit dimensions of 10.25 in height, 10.75 in width and 4.5 in depth.
