What it delivers
The Stiebel Eltron DHC 6-2 6 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 6 kW on 240 volts. Its listing gives a maximum flow of 0.5 GPM.
Expect about 0.5 GPM with cold winter water (a 70°F rise) and 0.5 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. Size it to your fixtures.
At 240 volts 6 kW is about 25 amps. A licensed electrician confirms the panel, the service and the wire before it goes in.
Small units like this suit one sink or a low-flow shower close by; at a kitchen sink's 1.5 GPM the water won't rise as far.
Listed details: material: Copper; model: DHC 6-2.
The listing gives dimensions of 7.31 in (W) x 14.37 in (H).
