Who it fits
Good fit for
This unit suits single sinks or showers where flow rates under 2.59 GPM are sufficient. It works well for apartments or homes with existing 240 V circuits. The smart features help you monitor usage remotely. The scale inhibitor protects the core in areas with hard water. You get instant hot water without waiting for a tank to refill. The compact size fits behind sinks or in closets. It is ideal for those wanting energy savings through on-demand heating.
Who should skip it
Skip this model if you need to run multiple fixtures at once. The 2.59 GPM limit may struggle with showers and sinks running together. You need a dedicated 240 V circuit with sufficient amperage. The 11 kW output may not handle high-demand households. If you live in a region with very hard water, the filter needs frequent replacement. The unit does not include a remote control. It is not suitable for whole-house heating in large homes.
Verdict: This heater delivers efficient, on-demand hot water for low-flow applications. Its smart features and scale protection add value for single-point use.
Key specs explained for you
Wattage: 11 kW
This power rating determines how much energy the unit draws to heat water instantly. At 11 kW, it is designed for single-point applications like a kitchen sink or a bathroom shower. Higher wattage models handle multiple fixtures or higher flow demands. You should match this spec to your home’s electrical capacity to ensure safe operation and consistent performance.
Flow Rate: 2.59 GPM
Gallons per minute indicates the volume of hot water delivered. A 2.59 GPM output suits one faucet or shower at a time. If you need simultaneous use, such as a shower and a sink, this flow may drop. Compare this against your typical usage habits to ensure the unit meets your daily hot water needs without pressure loss.
Voltage: 240 V
This voltage requirement means the heater needs a dedicated 240-volt circuit, similar to a large dryer or oven. Standard 120-volt household outlets cannot power this unit. You must verify your electrical panel has the capacity and the correct wiring. Incorrect voltage can damage the unit or create a safety hazard during installation.
Temperature Control: 86°F to 140°F
This range allows you to adjust water heat from mild to very hot. The upper limit of 140°F helps combat hard water scaling and ensures sanitation. Lower settings save energy for hand washing. You can dial in the exact comfort level you prefer. This flexibility ensures you get the right temperature for different tasks throughout the day.
Physical design and build details
The Electrolux 11 kW unit measures 12.8 by 8.9 by 3.3 inches according to the listing. It weighs 7.8 pounds and features a pearl white finish. The compact footprint allows for flexible installation in tight spaces. A side water outlet provides additional routing options for plumbing connections. This slim profile helps save space compared to bulkier traditional heaters.
The heating core is made of copper, which resists scale buildup. An external inlet pre-filter includes a replaceable scale inhibitor cartridge. You swap this cartridge every six to twelve months to protect the element from corrosion. This design helps maintain efficiency and extends the unit's lifespan. The casing is flame-retardant and rated IPX4 for waterproof protection.
Controls are managed via smart Wi-Fi connectivity. You can monitor and adjust the temperature from your phone using Alexa or Google Home compatibility. The temperature range spans from 86°F to 140°F. Self-modulating power automatically adjusts energy use based on demand. This feature ensures you only use the energy needed for your current hot water needs. The unit is CSA and UL certified with six safety protections including dry-heating and overheat safeguards.
Setup and everyday use guide
Installation requires a dedicated 240 V circuit to support the 11 kW power draw. The compact dimensions of 12.8 by 8.9 by 3.3 inches allow for flexible placement in tight spaces. A side water outlet simplifies plumbing connections, reducing the need for complex piping arrangements. You must ensure your electrical panel can handle the load, as this unit draws significant current to heat water instantly.
Daily operation relies on self-modulating power technology. The unit automatically adjusts its energy output to match your hot water demand. This means it uses only the energy needed for the current flow rate, which is up to 2.59 GPM. You get steady, full-pressure hot water ranging from 86°F to 140°F without the standby losses associated with traditional tank heaters. The copper core resists scale buildup, maintaining flow strength over time.
For convenience, the smart Wi-Fi feature lets you control and monitor the temperature from your phone. It is compatible with Alexa and Google Home, allowing voice commands for adjustments. Maintenance involves replacing the external inlet pre-filter cartridge every 6 to 12 months. This scale inhibitor protects the heating element from corrosion and keeps the unit efficient. The unit includes six safety protections, such as dry-heating and overheat prevention, ensuring safe operation during regular use.
Before You Buy This Unit
You need a dedicated 240 V circuit to support the 11 kW power draw. Ensure your electrical panel has space for this load. The unit delivers up to 2.59 GPM, so it suits single sinks or showers, not whole-house use. Check your inlet water temperature. Colder source water reduces flow rate at this wattage. You must install the external scale inhibitor filter. Replace the cartridge every 6 to 12 months to protect the copper core. This maintenance prevents corrosion and keeps efficiency high. The slim design fits tight spaces, but verify your plumbing allows for the side outlet. Compare this model against the other 1 options on this page. If you need higher flow, consider the 14 kW or 18 kW variations. This unit is for targeted, efficient heating with smart controls. It lacks whole-house capacity but excels in specific spots.
Check before you buy
- Verify you have a dedicated 240 V circuit available.
- Confirm the 2.59 GPM flow meets your single fixture needs.
- Check inlet water temperature impact on final output temperature.
- Ensure space for the external scale inhibitor pre-filter.
- Compare against higher wattage models if whole-house use is needed.
