  • Note: This model C3000 (3kW 120V) mini tankless 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 C6000 (6kW 240V) first, which is hard-wired
  • Easy to Use: Enlarged LED digital display with knob control, this point of use water heater 120V is very easy to use. 1 knob for power ON/OFF and temperature adjustment, offering a better user experience than others 3 little touchscreen buttons. You can adjust the temperature between 30C and 55C
  • Multi-protective and Intelligent: Every Lecloc water heater undergoes strict tests to ensure the safety of use. This instant water heater has multiple safety features, including leakage protection, overheat protection, dry combustion protection, high water pressure protection, IPX4 waterproof and is drop-test passed. Also this small electric water heater has functions of automatic fault diagnosis and constant temperature memory, very safe and smart to use
  • Efficient: This 3kW 120V 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

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. "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.

Tips for easy installation of a tankless water heater for a sink.
Size: 3kW 120V
Excellent choice for warm water at a sink. The 3000 model is a convenient plug-in installation. Easy installation once you do the gymnastics of clearing out and accessing the cabinet under your sink. You’ll need to purchase a connector between the device and the hot water faucet but this is available at your local home improvement store such as Home Depot or Lowe’s. I needed a longer 12” connecting hose with female 1/2” connectors. Takes about 20 minutes to install once you are prepped. Provides warm water quickly. Suggest you install top slider attachment first followed by screwing in fastener in bottom hole. Check that device is vertical before screwing in bottom fastener. I found it easier to attach the cold and hot water connectors to device before screwing device to back of cabinet wall under sink. ... show more

Garbage
Size: 3kW 120V
After installing I noticed that the pressure had to be turned down to a trickle just to be luke warm. It's made of cheap plastic and probably wouldn't last long if it did get hot. So I took it out and got ready to return just to find out I missed the return date by 8 days. If I could give it a 0 starts I would have. ... show more

Under the sink tankless water heater.
Size: 3kW 120V
The hot water in our kitchen would take 30 to 40 seconds to reach the sink. This is my first experience with a tank less hot water heater and maybe this is common. The water is warm within 5 seconds, but not hot. Within a few more seconds it has started to get mildly hot. After the water from the main hot water heater reaches the sink is it blazingly hot. So the performance is less than I expected, but better than what I had. Fits nicely under the sink. DIY installation. ... show more

Why all the stars?
Size: 3kW 120V
After trying to get even bath water temp from this unit, I am mystified by all the rave reviews. We don't have a water heater in our business in a small Texas town, but our back room has a sink with 2 water inputs, hence me trying to make one hot. If I didn't turn down the included water feed dial to almost shut, the water temp is barely warm, so even at a trickle nothing even approaches "hot". I would not recommend this to anyone. And after this experience, I believe my best bet is a small tank that stores hot water rather than trying to heat the incoming water on the fly. At least I could get a couple gallons of hot water until the tank emptied and needed to reheat. ... show more
