  • Note: This model C3000 (3kW 120V) mini tankless electric water heater is designed for low-flow use only, not suitable for showers or multiple taps at once. The output water temperature is affected by many factors, including the water heater wattage (heating capacity), inlet water temperature and water flow. For a better warm water use experience, we recommend that you consider our higher wattage model 6.5kW 240V first, which is hard-wired
  • Easy to Use: Large LED digital display with big control knob, this point of use water heater 120V is easy to install and use. 1 knob for power ON/OFF and temperature adjustment, offering a better use experience than others 3 little touchscreen buttons. You can adjust the temperature between 30C and 55C
  • Multiple Safety Features and Intelligent Design: Every Lecloc water heater is strictly tested to ensure reliable performance. This instant water heater is engineered with comprehensive safety protections, including leakage protection, overheat protection, dry combustion protection, high water pressure protection, IPX4 waterproof and is drop-test passed. Plus, it has functions of automatic fault diagnosis and constant temperature memory. Very safe and smart to use
  • Efficient: This 3kW 120V small on demand water heater under sink is suitable for 1 point of use. It can provide 24-hour endless warm water without the need for preheating, saving much compared to tank water heaters

Description

"The temperature adjustment is great which you simply do not get with a traditional hot water tank, and with a memory function built in we can be assured it will remain at the last setting we used it on and not have the need for constant adjustments to be made." Unlike traditional tank-type water heater that is quite big taking up immense space, our mini tankless water heater is compact and wall-mountable. It saves space while offering 96% thermal energy efficiency, heating water only when needed, making it an excellent addition to kitchens, bathrooms, or under-sink setups. This 3kW 120V point of use water heater is not meant for hot baths or showers, but for dishwashing, hands washing, hair washing or bathing the baby puppy, it will do the trick without issue. The instant hot water heater only heats when the faucet is open, so you're not paying to keep a tank hot all day. Enjoy peace of mind with our round-the-clock expert assistance. Whether it’s a midnight installation question or a weekend use concern, our dedicated support team delivers prompt, professional solutions — because your comfort shouldn’t keep business hours. This water heater features leakage protection, overheat protection, dry combustion protection, high water pressure protection, etc. And it includes automatic fault detection and memorizes your preferred temperature settings, reverting to the last or most frequently used temperature when restarted. 96% thermal efficiency with no standby heat loss to save you time, water, and money. The scale-free tankless water heater runs on electricity and doesn't hold any water, there is no venting and virtually no maintenance required. C3000 C3500 C6000 E65 Pro E65 ET25 (℉) ET25 (℃)

Compact and Convenient
Style: 6kW 240V
Installation was relatively simple for someone with basic plumbing and electrical experience, though I’d recommend professional help if you're unfamiliar with 240V wiring. Performance-wise, it delivers hot water almost instantly, which is perfect for handwashing, dish rinsing, or bathroom use. We used it for our kitchen sink. The temperature remains consistent, and it heats just what you need—no more waiting for a large tank to warm up. It’s also a great energy-saving solution, especially for households that want on-demand hot water in a remote bathroom or workshop. ... show more
