The Stiebel Eltron DHC 4-3 Classic Single Sink Point-of-Use Electric Tankless Water Heater - 202649 is designed specifically for installation at the point of use, this model operates on 277V and delivers 4.5 kW of heating power through its durable copper construction. It eliminates standby heat losses by heating water instantaneously as it flows, ensuring energy is not wasted. The unit's heating element is safeguarded by a flow switch to prevent dry-firing and ensure longevity. Quiet operation is guaranteed through hydraulic control, while the inclusion of a safety high limit with manual reset offers added security. Its rugged, all-copper design promises many years of reliable service, making it an ideal choice for anyone looking to optimize their hot water system.

1 This is our recommendation for overcurrent protection sized at 100% of load (DP for 240/208/277 V & SP for 120 V models). Check local codes for compliance if necessary. Tankless water heaters are considered a non-continuous load.
2 Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
3 Suitable for supply with cold water only.
