What it delivers
The Stiebel Eltron DHC 4-3 Classic 4.5 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 4.5 kW on 277 volts.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 0.7 GPM, less than one 2 GPM shower; in winter, at a 70°F rise, about 0.4 GPM, less than one 2 GPM shower. Size it to your fixtures.
At 277 volts 4.5 kW is about 16 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
Point-of-use units go under or beside one sink, where a short pipe run means hot water in seconds.
From the listing: features: Quiet Operation; material: Copper; model: DHC 4-3 Classic.
The listing gives dimensions of 7.31 in (W) x 14.37 in (H).
