Power and Installation Differences

Wattage and Heat Output

Edge: LECLOC 6kW 240V Hard-wired Under Sink Heater

The LECLOC 3kW 120V Mini Tankless operates at 3000 watts, while the LECLOC 6kW 240V Hard-wired Under Sink Heater delivers 6000 watts. This significant difference in power affects how much water you can heat at once. The 3kW model is designed for low-flow use only and is not suitable for showers or multiple taps. The 6kW model provides higher heating capacity, making it more effective for demanding tasks. If you need faster or hotter water for a kitchen sink, the higher wattage unit is the better choice. The lower wattage unit is sufficient for basic hand washing or light use.

Voltage and Electrical Needs

Edge: LECLOC 3kW 120V Mini Tankless

Electrical requirements differ between the two models. The LECLOC 3kW 120V Mini Tankless plugs into a standard 120V outlet, making it easy to install in most homes without major electrical work. In contrast, the LECLOC 6kW 240V Hard-wired Under Sink Heater requires a 240-volt power supply and a 30-amp double-pole circuit breaker. You must consult a licensed electrician to ensure your home can handle this load. If you already have a 240V circuit available under the sink, the higher voltage model is viable. Otherwise, the 120V plug-in option is much more convenient and flexible for installation.

Physical Dimensions

Edge: Tie

Both units share the same compact footprint, measuring 7.1 inches wide, 9.8 inches high, and 2.8 inches deep. This identical size allows them to fit easily under most standard sinks. The LECLOC 6kW 240V Hard-wired Under Sink Heater weighs 4 pounds, providing a sturdy build. The weight and dimensions of the 3kW model are not explicitly listed in the data, but the similar design suggests comparable bulk. Since both are designed for point-of-use installation, space constraints are not a deciding factor for either option. You can install either model in tight spaces without worrying about clearance issues.

Temperature Control Range

Edge: Tie

Both heaters offer the same temperature adjustment capabilities. You can set the output water temperature between 30℃ and 55℃ on both models. Each unit features a large LED digital display and a single control knob for power and temperature adjustment. This interface is described as easier to use than systems with multiple small touchscreen buttons. The constant temperature memory function is present in both, remembering your preferred settings. Whether you choose the 120V or 240V model, you get precise control over water warmth, ensuring consistent comfort for hand washing or dish rinsing.

Safety and Certifications

Edge: Tie

Safety features are nearly identical across both models. Each heater includes leakage protection, overheat protection, dry combustion protection, high water pressure protection, and IPX4 waterproofing. Both have passed drop tests and feature automatic fault diagnosis. The LECLOC 6kW 240V Hard-wired Under Sink Heater explicitly lists IPX4 certification in its key specs. The 3kW model mentions the same protections in its features list. These comprehensive safeguards ensure reliable performance and protect against common electrical and water hazards. You can trust that either unit is engineered for safe operation in wet environments like under-sink installations.
