Stiebel Eltron DHC-E 8/10 is actually two models in one - it has the added advantage of the selectable power output of 7.2 kW (Stage 1) or 9.6 kW (Stage 2) during installation via a jumper.
240V/208V - copper tankless electric with thermostat
DHC-E can deliver hot water to a single sink, multiple sinks, or in certain conditions, low-flow showerheads.
You can control temperature simply by setting a dial. DHC-E models have the exclusive Electronic Temperature Control. This allows the temperature of the water to remain the same regardless of flow fluctuations.

*DHC-E 8/10 is a single unit that is switchable at installation via jumper for output at 7.2 kW (Stage 1) or 9.6 kW (Stage 2).
1 Overcurrent protection sized at 100% of load. Tankless water heaters are considered a non-continuous load.
2 Copper conductors with a temperature rating of 75 °C or greater must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
These are recommendations. Check local codes for compliance if necessary.
