ECO 11 and POU 6 Spec Breakdown
Wattage and Capacity
Power output defines what each unit can handle. The EcoSmart ECO 11 operates at 13 kW, providing significant heating power for higher demand scenarios. In contrast, the EcoSmart POU 6 delivers 6 kW of power. This lower wattage suits applications where energy usage needs to be minimized or where electrical circuits have limited capacity. The ECO 11’s higher rating allows it to heat water more aggressively, making it suitable for tasks requiring more thermal energy. The POU 6’s 6 kW is sufficient for smaller, localized heating needs. You should choose based on your required heat output.
Intended Use and Flow
Application scope differs significantly between these two models. The POU 6 is explicitly designed for single point-of-use applications, such as hand sinks in RVs, boats, restaurants, hotels, and medical offices. It supports low flow rates not exceeding 1 GPM. The ECO 11 is configured for climates with incoming water temperatures around 60 degrees, suggesting a broader utility for general household or small business use rather than just a single sink. The POU 6’s specific design for low-flow, single-point use makes it ideal for specific, isolated fixtures, while the ECO 11 is more versatile for varied heating demands.
Physical Dimensions
Size affects where you can mount each unit. The ECO 11 measures 10 inches in height, 13.5 inches in width, and 6.5 inches in length. It occupies a larger footprint on your wall or cabinet. The POU 6 is more compact, measuring 6 inches in height and 11 inches in width. This smaller form factor allows for installation in tighter spaces, such as under small sinks or in confined utility closets. If space is a premium constraint in your installation area, the POU 6’s reduced dimensions offer a practical advantage for placement flexibility.
Weight
Weight impacts mounting requirements and handling during installation. The ECO 11 weighs 6.5 pounds, which is moderate for an electric tankless unit. The POU 6 is lighter at 3.85 pounds. This weight difference is minor but can matter when considering the load on mounting brackets or shelves, especially in older structures or lightweight cabinetry. The lighter POU 6 places less stress on your wall or shelf, simplifying the installation process. Both units are manageable for a single installer, but the POU 6 is easier to lift and position.
Voltage Compatibility
Both units require specific electrical infrastructure. The ECO 11 operates at 240 volts, as does the POU 6. This means both require a dedicated circuit capable of handling the respective amperage for their wattage. You will need to ensure your electrical panel can support the load for either choice. Since both share the same voltage requirement, your existing 240-volt wiring may be compatible with either model, provided the breaker size matches the amperage draw of the selected unit. This similarity simplifies electrical planning for either option.
Which unit fits your hot water needs
Homeowners needing whole-house hot water
The ECO 11 offers 13 kW of power and higher flow capacity. Its larger dimensions accommodate more robust heating elements. This unit handles multiple fixtures better than the compact alternative. Choose this if you require consistent hot water for sinks, showers, or appliances in a residential setting.
RV or boat owners with limited space
The POU 6 is designed for low flow rates up to 1 GPM. It weighs only 3.85 pounds and measures 11 by 6 inches. This compact size fits tight spaces in recreational vehicles or boats. It is ideal for single sink applications where minimal water usage is typical.
Users installing a dedicated hand sink
This model targets point-of-use locations like medical offices or restaurants. It provides 6 kW of heating power for single fixtures. The small footprint allows easy mounting near the sink. Select this unit if you only need hot water for one specific tap rather than a full household supply.

Frequently asked questions
Can the EcoSmart ECO 11 heat water for multiple sinks?
The ECO 11 is designed primarily for single-sink installations in moderate climates. Its 13 kW power output supports higher flow demands than the POU 6. While it handles more robust heating elements, it is not intended for whole-house supply or multiple simultaneous fixtures.
What is the weight difference between the ECO 11 and POU 6?
The ECO 11 weighs 6.5 pounds, while the POU 6 weighs 3.85 pounds. The ECO 11 is slightly heavier due to its larger internal components. The POU 6 is lighter, making it easier to mount in tight spaces like small vehicles or offices.
Do both units require a 240-volt electrical connection?
Yes, both the ECO 11 and POU 6 operate on 240-volt electric power. The ECO 11 uses 13 kW of wattage, and the POU 6 uses 6 kW. You must ensure your home has the dedicated circuit capacity for either unit before installation.
Which model is better for a small office or RV?
The POU 6 is the better choice for small offices or recreational vehicles. It is a specialized unit for low-flow sinks and fits buyers needing a compact, dedicated hot water source. Its smaller size and lower power consumption suit limited electrical systems in mobile environments.
How much space does the ECO 11 take up?
The ECO 11 measures 13.5 inches in width, 10 inches in height, and 6.5 inches in length. It is a space-saving solution that fits easily in closets or utility rooms. The compact design allows for flexible installation in homes with limited wall space.
Can the POU 6 handle high-flow showers?
No, the POU 6 is not suitable for high-flow showers. It is designed for low-flow single sink applications only. Its 6 kW output cannot sustain the water volume and temperature required for showering. Use the ECO 11 for higher demand scenarios instead.
Is the ECO 11 suitable for cold climates?
The ECO 11 is best for moderate climates. In very cold regions, incoming water temperatures are lower, which reduces the unit's effective flow rate. You may need a higher wattage unit or multiple devices to maintain adequate hot water temperature during winter months in cold areas.
