The Stiebel Eltron DHC Trend series tankless water heaters are designed for single sink applications. The DHC 3/3.5-1 Trend features Stiebel's proven and trouble-free Direct Coil™ heating system for improved hard water resistance. It self-cleans while offering a faster heat-up time and lower latent heat retention.

By producing hot water on demand only as it is being used, the DHC 3/3.5-1 Trend is extremely energy efficient. A sophisticated water flow sensor recognizes when hot water is being used and when it has been turned off, so the unit will activate and deactivate automatically so it only runs when you are actually using water. This eliminates standby thermal heat losses associated with traditional tank type water heaters. Accordingly, you can expect to see a significant cost reduction over the operating cost of a conventional water heater.

• Direct Coil™ heating system incorporates proven and trouble-free technology that self-cleans, enhancing limescale resistance.
• Switchable kW power output enables each model to accommodate a wider range of applications.
• Provides on-demand hot water, ensuring an uninterrupted supply as long as needed. However, it is crucial to match the model size carefully to the application for optimal performance.
• Perfect for single sink applications.
• Features a sleek European design that is significantly smaller than a tank, requires no venting, and allows space-saving installation near the point-of-use.
• The Direct Coil™ heating system ensures rapid heat-up and response.

Do You Have Hard Water?

If your water hardness trends above 7 grains per gallon (GPG) or 120 mg/l (ppm), you should consider hard water treatment prior to your tankless water heater. If your hardness exceeds 12 GPG or 200 mg/l (ppm), hard water treatment is strongly recommended.

Hard water treatment helps maintain performance and efficiency, ensures optimal water flow and pressure, and protects your heater from pre-mature failure due to mineral build-up inside the heating module and other components.
