Design and Build Quality
One of the most appealing aspects of the EcoSmart ECO 11 Electric Tankless Water Heater is its sleek and compact design. Traditional tank heaters are often large and require significant storage space, which can be problematic in smaller homes or apartments.
This unit, however, measures only 11.5 inches high and 8 inches wide, making it approximately 90 percent smaller than conventional water heaters.
The minimalist exterior design allows it to blend easily with utility rooms, closets, cabinets, and wall installations. Its durable construction is designed for long-term reliability and efficient heat transfer.
The front panel includes a clear LED display that shows the temperature setting and system status. This display makes monitoring and adjusting the water temperature simple and convenient.
Compact Size for Flexible Installation
Space efficiency is one of the biggest advantages of the EcoSmart ECO 11 tankless water heater. Because it does not require a storage tank, the heater can be installed in areas where traditional heaters cannot fit.
Common installation locations include:
- Bathroom sinks
- Kitchen sinks
- Office breakrooms
- Small apartments
- Guest bathrooms
- Utility rooms
- Point-of-use installations
The lightweight design and wall-mount configuration make installation straightforward for professional plumbers or electricians.
In many homes, the heater is installed close to the water outlet. This reduces the distance hot water must travel through pipes, which helps deliver faster hot water and reduces energy loss.
Endless On-Demand Hot Water
One of the most significant advantages of tankless water heaters is their ability to produce endless hot water. Traditional tank heaters store a limited amount of heated water. Once the tank is emptied, users must wait for it to refill and heat again.
The EcoSmart ECO 11 Electric Tankless Water Heater eliminates this limitation by heating water instantly when needed.
As long as water flows through the system, the heater continues producing hot water. This feature is particularly useful in homes with frequent handwashing, dishwashing, or shower use.
Additionally, the heater monitors water temperature continuously and adjusts heating power to maintain stable temperature output.
Self-Modulating Technology Explained
The patented self-modulating technology built into the EcoSmart ECO 11 plays a crucial role in its efficiency and performance.
Traditional electric heaters typically operate at full power whenever they are activated. This can result in unnecessary energy consumption when full heating capacity is not required.
Self-modulating technology works differently.
The system automatically adjusts the heating power based on:
- Incoming water temperature
- Flow rate
- Desired temperature setting
For example, if the incoming water is relatively warm, the heater uses less energy to reach the target temperature. If the water is colder, the system increases heating output accordingly.
This intelligent energy control helps optimize performance while minimizing electricity consumption.
Energy Efficiency and Cost Savings
The EcoSmart ECO 11 Electric Tankless Water Heater boasts an impressive 99 percent thermal energy efficiency rating.
This means nearly all the electricity used by the heater is converted into heat for the water. Very little energy is wasted during the process.
Traditional tank heaters are much less efficient because they constantly maintain heated water inside the tank, even when no one is using hot water. This standby heating results in energy loss and higher electricity bills.
Tankless heaters eliminate this issue because they heat water only when it is needed.
As a result, homeowners may experience noticeable reductions in energy costs, especially in households with moderate hot water usage.
Flow Rate Performance
The EcoSmart ECO 11 tankless water heater delivers a flow rate ranging between 1.3 and 3.1 gallons per minute depending on the incoming water temperature.
Flow rate depends on several factors, including:
- Groundwater temperature
- Desired output temperature
- Water pressure
- Simultaneous hot water demand
In warmer climates, the heater can achieve higher flow rates because the incoming water temperature is already relatively warm.
Typical applications for this heater include:
- Single bathroom
- Kitchen sink
- Bathroom sink
- Low-flow shower
- Office kitchenette
For larger homes requiring multiple simultaneous hot water sources, a higher-capacity model may be necessary.
Temperature Control and LED Display
Temperature accuracy is critical for a comfortable hot water experience. The EcoSmart ECO 11 Electric Tankless Water Heater includes a digital temperature control system that allows users to select their preferred water temperature.
The integrated LED display shows the temperature setting clearly, making adjustments easy.
One of the standout features is the system’s ability to maintain temperature within one degree of the selected setting. This precision ensures consistent water temperature without sudden fluctuations.
This level of accuracy enhances comfort during activities such as washing hands, washing dishes, or taking a shower.
Installation Requirements
The EcoSmart ECO 11 operates at 240 volts and requires a dedicated electrical circuit capable of supporting its 54 amp draw.
Because of these electrical requirements, professional installation by a licensed electrician is typically recommended.
Key installation considerations include:
- Dedicated circuit breaker
- Proper electrical wiring
- Suitable mounting location
- Adequate water pressure
- Proper plumbing connections
The compact design makes it easier to install compared to bulky tank heaters, but electrical capacity must always be verified before installation.
Ideal Applications
The EcoSmart ECO 11 Electric Tankless Water Heater is designed primarily for point-of-use or small-scale hot water applications.
It performs best in situations where only one or two hot water outlets are used at a time.
Typical installation scenarios include:
- Apartment bathrooms
- Small homes
- Office kitchens
- Studio apartments
- RV or guest house setups
- Utility sinks
Because it heats water instantly, it can significantly reduce wait time for hot water when installed close to the outlet.
