Which one should you choose?
Choose LECLOC 3kW 120V Electric Tankless Water Heater if
- You only have a standard 120V outlet nearby.
- You need warm water for a single low-flow sink.
- You prefer a simple plug-in installation without an electrician.
Choose LECLOC 6kW 240V Hard-wired Under Sink Heater if
- You have a dedicated 240V circuit with a 30-amp breaker.
- You need higher flow rates for kitchen or bathroom sinks.
- You want maximum heating capacity for colder inlet water.
Verdict: Select the 3kW 120V model if you are limited to standard household outlets and only need point-of-use warmth for one sink. Choose the 6kW 240V hard-wired unit if you have the electrical infrastructure and require stronger heating performance for more demanding tasks.
Power and Voltage Comparison
Voltage and Power
Product A uses 120 volts with 3kW heating capacity, while Product B requires 240 volts and delivers 6kW. The higher wattage in Product B means it can heat water faster and handle slightly higher flow rates than the 3kW model. You need to check your home’s electrical panel to see if you have the correct circuit for the 240V unit. The 120V model plugs in, making it easier to install in spaces with standard outlets. However, the 6kW unit is significantly more powerful for tasks requiring warmer water.
Installation Method
Product A is a plug-in unit, which allows for straightforward connection to a standard 120V outlet. Product B is hard-wired and requires a dedicated 30-amp double-pole circuit breaker. You must consult a licensed electrician for the 6kW installation to ensure your home’s wiring can handle the load. The plug-in design of the 3kW model offers more flexibility for renters or quick swaps. The hard-wired setup of the 240V model is more permanent but provides the necessary power for higher performance.
Dimensions and Size
Both heaters share identical physical dimensions: 7.1 inches wide, 9.8 inches high, and 2.8 inches deep. This compact footprint allows them to fit in small under-sink cabinets without taking up much space. The weight is nearly the same, with Product A at 3.9 pounds and Product B at 4 pounds. You can install either model in kitchens, bathrooms, or basements where space is tight. The consistent size means you do not need to modify existing cabinetry for either option.
Control Interface
Both units feature an LED digital display and a single control knob for power and temperature adjustment. This knob design allows you to set the temperature between 30℃ and 55℃ easily. The interface is described as more user-friendly than models with multiple small touchscreen buttons. You can adjust the heat precisely to your preference. Both models include constant temperature memory, so your preferred setting is saved after power cycles. The control experience is identical for both the 3kW and 6kW versions.
Safety Features
Product A and Product B both include comprehensive safety protections. These features include overheat protection, leakage protection, dry heating protection, and over-pressure protection. Both units have IPX4 waterproofing and have passed drop test certification. They also share automatic fault diagnosis capabilities. These safety measures ensure reliable operation in wet under-sink environments. You get the same level of protection and smart monitoring regardless of which wattage you choose.
Which LECLOC Model Fits Your Needs
Renters or those without 240V circuits
This 3kW 120V plug-in model works with standard outlets. It suits low-flow sinks where high heating power is unnecessary. The 120V connection avoids the need for a licensed electrician or a dedicated 30-amp double-pole circuit breaker. You get the same LED controls and compact size as the higher-wattage option, making it the practical choice for existing electrical setups.
Users needing higher flow or faster heating
The 6kW 240V hard-wired unit delivers double the heating capacity. This higher wattage allows for faster water heating and better performance at slightly higher flow rates. You must install a dedicated 240V circuit with a 30-amp breaker. If your electrical system supports this upgrade, this model provides more consistent warm water for kitchen or bathroom sinks compared to the lower-power alternative.
Those wanting identical controls and safety features
Both units share the same physical dimensions, LED display, and single-knob temperature control. They both offer overheat, leakage, and dry heating protection with IPX4 waterproofing. If you do not need the extra 3kW of power, the 120V plug-in model gives you the same smart features and compact design without requiring complex hard-wiring or a specialized electrical circuit.
