What it delivers
The Stiebel Eltron DHX 15-2 Plus 14.4 kW Electric Tankless Water Heater is a compact electric tankless rated at 14.4 kW on 240 volts.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 2.2 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 1.4 GPM, less than one 2 GPM shower. Size it to your fixtures.
At 240 volts 14.4 kW is about 60 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
Electric tankless units need no venting and no gas, and work best where inlet water stays mild, because every degree of rise costs flow.
