Stiebel Eltron 202646 DHC 3-1 Classic Electric Tankless Water Heater
3.0 kW • 120V • Compact Point-of-Use Solution for Single Sink Applications
The Stiebel Eltron DHC 3-1 Classic (Part #202646) is a compact, high-efficiency point-of-use electric tankless water heater engineered for single sink applications where space, energy efficiency, and reliability are critical. Designed with precision German engineering, this unit delivers instant, continuous hot water directly at the fixture, eliminating the inefficiencies of traditional tank systems.
Engineered for Reliable Point-of-Use Performance
The DHC 3-1 Classic operates using a flow-activated heating system, delivering hot water instantly as it passes through the unit. This eliminates standby heat loss and ensures that energy is used only when hot water is needed, making it an efficient solution for low-flow applications.
Designed specifically for handwashing sinks, the unit provides a controlled output optimized for consistent performance in environments where reliability and efficiency are essential.
Compact, Efficient Tankless Design
With its small footprint and wall-mounted design, the DHC 3-1 Classic installs directly at the point of use—typically under or near the sink—reducing heat loss through piping and delivering near-instant hot water.
Its compact European design allows installation in tight spaces such as cabinets or utility areas, making it ideal for both new construction and retrofit applications.
Proven Heating Technology and Durability
The unit features a copper-sheathed heating element housed within a copper cylinder, ensuring efficient heat transfer and long-term durability. The internal design helps prevent dry firing and supports consistent operation over time.
Built-in safety features include:
- A high-limit safety switch with manual reset
- Flow-activated operation for efficient performance
- Durable housing designed for long service life
These engineering elements contribute to reliable, maintenance-friendly operation in both commercial and residential settings.
