Who it fits

Key specs explained for LECLOC

Voltage: 240V

This unit requires a dedicated 240-volt electrical circuit, not standard 120V household outlets. You must have a 30-amp double-pole breaker installed by a licensed electrician. This higher voltage allows for faster heating but limits where you can place the heater. If your home lacks this infrastructure, you will need to upgrade your electrical panel or choose a lower-voltage model.

Wattage: 6kW

The 6000-watt heating element delivers rapid hot water for a single sink. This power level is sufficient for kitchen or bathroom faucets but may struggle with high-flow showers. It provides endless warm water without preheating delays. Compare this to lower-wattage units; the 6kW model heats water more quickly, making it ideal for quick handwashing or dish rinsing tasks.

Dimensions: 7.1 x 9.8 x 2.8 inches

The compact footprint allows installation under most standard kitchen or bathroom sinks. The slim depth of 2.8 inches fits into tight cabinetry without obstructing plumbing or storage. This size makes it suitable for apartments, dorms, or offices where space is limited. Ensure your sink cabinet has enough clearance for the unit and necessary electrical connections during installation.

Temperature Control: 30℃ to 55℃

You can adjust the output temperature using a single control knob, ranging from 30 to 55 degrees Celsius. This range covers most everyday needs, from cool rinsing to warm washing. The digital display shows the current setting for easy monitoring. This manual control offers a simpler experience than complex touchscreen interfaces, allowing for quick adjustments without navigating menus.

Certification: IPX4

The IPX4 rating means the unit is protected against water splashes from any direction. This safety feature reduces the risk of electrical hazards in damp under-sink environments. It ensures the internal components remain safe even if minor leaks occur. This certification is essential for any appliance installed near water sources, providing peace of mind regarding long-term durability and user safety.

Design and build overview

The listing describes this unit as a gray, compact device labeled C6000. It weighs 4 pounds and measures 7.1 by 9.8 by 7.1 inches. This small footprint allows it to fit under most standard sinks. You can place it in kitchens, bathrooms, or offices without taking up much space. The hard-wired design means it connects directly to your home’s electrical system. This removes the need for a plug but requires professional installation. You must have a 30-amp double-pole breaker ready before mounting.

Controls are handled by a single knob for power and temperature adjustment. You can set the water between 30 and 55 degrees Celsius. The listing notes this physical knob offers a better experience than small touchscreen buttons. An LED digital display shows the current settings. This layout keeps the interface simple and easy to use with wet hands. The gray finish is practical for hidden under-sink locations.

Safety features are built into the design. The unit includes overheat, leakage, and dry heating protection. It also has over-pressure protection and IPX4 waterproofing. These certifications suggest the internal components are sealed against moisture and dust. The listing mentions automatic fault diagnosis and constant temperature memory. These functions help maintain stable water heat without manual re-adjustment. The compact size and robust internal protections make it suitable for tight spaces.

Setup and everyday use

Installation requires a dedicated 240-volt circuit and a 30-amp double-pole breaker. You must hire a licensed electrician to handle the hard-wired connection. This electrical setup is non-negotiable for safe operation. The unit does not plug into standard outlets. Once installed, the device sits under the sink, drawing power directly from your home’s electrical system.

Daily operation centers on a single control knob. You turn the unit on and adjust the water temperature simultaneously. The digital LED display shows the current setting. You can set the output between 30℃ and 55℃. This single-knob interface is designed for straightforward adjustments without navigating complex menus. The unit remembers your last temperature setting, so you do not need to reconfigure it every time you turn it on.

The heater provides instant warm water for a single point of use. There is no waiting for a tank to preheat. The system includes automatic fault diagnosis to monitor its own status. Safety features like overheat, leakage, and dry heating protection engage automatically if issues arise. The IPX4 waterproofing rating means it can handle splashes in a typical under-sink environment. You simply turn the knob to the desired heat level, and the unit delivers consistent temperature immediately. This process repeats for every use, providing endless hot water without delay.

Before You Buy This Unit

You need to verify your home’s electrical capacity before proceeding. This LECLOC C6000 requires a dedicated 240-volt circuit with a 30-amp double-pole breaker. Standard household outlets will not work. You must hire a licensed electrician for the hard-wired installation. The unit is designed for a single point of use, such as one under-sink faucet. It cannot serve multiple fixtures simultaneously. Check that your plumbing connections match the inlet and outlet sizes. The compact dimensions allow it to fit in tight cabinets, but you must ensure there is enough clearance for maintenance access. While this electric model offers endless warm water, it differs significantly from gas units in installation complexity. You should compare this hard-wired setup against plug-in 120-volt alternatives if your electrical panel lacks the required capacity. Regular upkeep involves ensuring the IPX4 waterproofing remains intact and that the LED display functions correctly. The temperature range of 30℃ to 55℃ is suitable for handwashing and light cleaning tasks.

Check before you buy

• Confirm you have a 240V circuit with a 30-amp double-pole breaker.
• Hire a licensed electrician for the hard-wired connection.
• Verify the unit fits your under-sink cabinet dimensions.
• Ensure your plumbing connections match the heater’s inlet and outlet.
• Check if a single point of use meets your hot water needs.
