EcoSmart ECO 11 Electric Tankless Water Heater - 13 kW, 240V, Self Modulating Technology

Compact, On-Demand Hot Water Made Simple

The EcoSmart ECO 11 delivers on demand hot water with a compact footprint and intelligent heat control. With patented self modulating technology, the unit adjusts energy usage to match your hot water needs, helping you heat water only when you call for it and reducing energy waste. The system operates at 240 volts with a 13 kilowatt rating and draws about 54 amps, so electrical compatibility is an important consideration before installation.

In climates where incoming water temperature is 67 degrees Fahrenheit or warmer, the ECO 11 can supply hot water for up to two fixtures in warmer regions, or a single shower in cooler regions. This makes it suitable for bathrooms, small sinks, office breakrooms, or other low to moderate flow applications. The model is designed for point of use or small space installs, providing flexible hot water options without maintaining a tank.

Smart features that matter

• Endless on demand hot water with continuous temperature monitoring and flow control keeps performance steady within about one degree of the selected setting.
• Space saving design is 90 percent smaller than traditional tanks and can be mounted on a wall or placed at the point of use.
• High thermal efficiency, with most heat delivered directly into water only when called, helping reduce energy waste.
• Digital temperature control allows adjustments in one degree increments for precise comfort and consistent results.
• Flow and capacity range: approximately 1.3 to 3.1 gallons per minute depending on the inlet water temperature, with sizing guidance available.

Practical use cases and sizing guidance

• Best suited for a bathroom, a small sink, or an office breakroom where space is at a premium.
• In warmer climates it can support two fixtures; in colder climates it works well as a point of use for a sink or other low flow needs.
• Final sizing depends on inlet water temperature and desired hot water flow; consult the sizing guide to select the proper solution.
• Dimensions are compact at 11.5 x 8 x 3.75 inches, allowing installation in tight spaces or on a wall.

Before purchasing, verify that the ECO 11 is the right size for your hot water needs and electrical setup. The model is configured for climates where incoming water temperature is 67°F or higher, and performance can vary with temperature and flow. Ensure you have the appropriate electrical circuit and clearances for safe operation.
