What it delivers
The Stiebel Eltron DHC 8-2 7.2 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 7.2 kW on 240 volts.
Expect about 0.7 GPM with cold winter water (a 70°F rise) and 1.1 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. Check your house in the planner.
At 240 volts 7.2 kW is about 30 amps. The requirement calculator shows it at 208 V too; an electrician confirms the panel.
It's meant for a single fixture near the unit: it saves the wait for hot water there rather than heating a whole house.
Listed details: features: Energy Efficient, Safety Features; material: Copper; model: DHC 8-2.
The listing gives dimensions of 7.31 in (W) x 14.37 in (H).
