Endless On-Demand Hot Water
The primary appeal of tankless water heaters lies in their ability to provide hot water whenever it is needed. The EcoSmart ECO 11 delivers continuous hot water without the risk of running out, even during extended use.
Performance Highlights
- Instant activation when water flow begins
- No storage tank limitations
- Consistent output throughout use
- Ideal for repeated handwashing, showers, or sink use
The unit continuously monitors incoming water temperature and adjusts heating power accordingly, ensuring that hot water remains steady and dependable.
Patented Self Modulating Technology
At the core of the EcoSmart ECO 11 is its patented self-modulating technology. This intelligent system automatically adjusts the amount of energy used based on water flow and temperature demand.
How Self Modulation Improves Efficiency
- Reduces unnecessary energy consumption
- Maintains precise temperature control
- Adapts instantly to changes in water usage
- Enhances user comfort and safety
By matching energy input to real-time demand, the ECO 11 avoids overheating and minimizes electricity waste, making it both efficient and user-friendly.
Temperature Stability and Precision
Temperature consistency is essential for comfort and safety. The EcoSmart ECO 11 is engineered to maintain water temperature within one degree of the selected setting.
Benefits of Precise Temperature Control
- Eliminates sudden temperature fluctuations
- Prevents scalding risks
- Improves shower and sink comfort
- Reliable performance in varying conditions
This level of accuracy is especially important in applications such as handwashing stations and bathrooms, where stable water temperature enhances everyday convenience.
Energy Efficiency and Cost Savings
The EcoSmart ECO 11 electric tankless water heater is designed with energy efficiency as a top priority. With a thermal efficiency rating of up to 99%, nearly all the electricity consumed is converted directly into heating water.
Energy-Saving Advantages
- Heats water only when needed
- No standby heat loss
- Lower monthly energy costs
- Reduced environmental impact
Traditional tank heaters maintain hot water around the clock, even when not in use. In contrast, the ECO 11 activates only during demand, helping households and businesses reduce wasted energy.
Flow Rate and Performance Range
Flow rate is a critical factor when selecting a tankless water heater. The EcoSmart ECO 11 delivers a flow rate between 1.3 and 3.1 gallons per minute, depending on the inlet water temperature.
Flow Rate Considerations
- Higher flow in warmer climates
