What it delivers
The Stiebel Eltron DHC 3-2 3.3 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 3.3 kW on 240 volts.
Flow depends on how cold the incoming water is. Our estimate from its input: 0.5 GPM at a 45°F rise, falling to 0.3 GPM at 70°F, which is less than one 2 GPM shower on a cold-climate winter day. Try your own inlet temperature.
At 240 volts 3.3 kW is about 14 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
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.
Also on the listing: material: Copper; model: DHC 3-2.
The listing gives dimensions of 14.18 in (W) x 7.93 in (H).
