Commercial three-phase tankless heater

The Eemax ED020480T2T is an electric tankless water heater built for commercial and industrial environments. It operates on a 480 V AC three-phase supply and draws 24 A at a full power consumption of 20000 W. The unit delivers water between 100 and 140 degrees F at a maximum flow rate of 4 gpm.

Wall-mount installation with half-inch inlet

The heater measures 12.25 in high, 18.25 in wide and 4.5 in deep for indoor wall mounting. A cold inlet size of 1/2 in connects directly to the supply line. Minimum flow activation is 0.7 gpm, so low-demand fixtures may not trigger the unit. Three-phase wiring and 480 V service must be verified before installation.

Suits high-demand commercial sites

This model suits facilities that require continuous hot water at 480 V three-phase power. It is not for residential single-phase electrical systems. Buyers who need higher flow rates or a different voltage should look at other configurations.
