ECO 11 Tankless Water Heater, Electric, 11-kW

The EcoSmart ECO 11 is an electric tankless water heater that delivers hot water on demand without storing water in a tank. Unlike traditional tank heaters that maintain water temperature constantly, this unit heats water only when you need it, reducing energy waste and providing endless hot water for bathrooms, kitchens, office break rooms, and other point-of-use applications. Its compact design makes it ideal for homes and spaces where room is limited.

This tankless water heater is engineered for climates where incoming water temperature is 67°F or above and delivers consistent hot water at flow rates between 1.3 and 3.1 gallons per minute, depending on inlet water temperature. The unit is approximately 90% smaller than traditional tank heaters and can be installed on a wall or directly at the point of use, making it a space-saving solution for targeted hot water needs.

Features and Benefits

• Digital Temperature Control: Adjustable in 1-degree increments with continuous monitoring to maintain consistent water temperature within 1 degree of your selected setting.
• Self-Modulating Technology: Automatically scales heating elements based on water flow demand, ensuring optimal energy efficiency.
• On-Demand Hot Water: Provides endless hot water when needed without the wait time or standby energy loss of tank heaters. Delivers up to 2 gallons per minute, sufficient for one showerhead at 1.5 GPM plus one sink.
• Space and Energy Savings: Ninety percent smaller footprint than tank heaters with 99% thermal energy efficiency. Only consumes power during active hot water demand.
