  • 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 6kW 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 very easy to 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 rigorously 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 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 (℃)

Fit, and works
Perfect thread size and small lever allowed for fitment in a tight space. I added a 1/2" mpt close nipple, and a 1/2" fpt coupling, and another 1/2" mpt close nipple to get the spacing correct so I could install it easily. It will take some creativity, but that is unavoidable with any of these valves. I couldn't get the male threads on this to seal in a pvc coupling, but the female side sealed great with the included gasket/washer. This valve was such a huge quality of life upgrade for our water heater that gets winterized a dozen times each winter. ... show more

Used to replace 50 gal hot water heater in clubhouse that has only 3 sinks. Helped lower energy bill

I regret this purchase
Size: 3kW 120V
I am disappointed with this product. I purchased the 3kW 120v heater to use under our sink in-line with our existing hot water heater. It is on a dedicated circuit. Previously, it would take about 30 seconds to get hot water. With this unit, it varies anywhere from 20 seconds to 45 seconds with help from our house water heater. It does not have the power to do anything but warm the water on a kitchen sink. The instructions are in broke English. Normally, that is to be somewhat expected, but it is bad enough to be borderline unusable. The manual includes phrases like, “The ground wire should connect the underground fully.” The cold water inlet was also dripping wet when I unboxed the unit—ours had been previously installed and returned. Incredibly disappointed overall. ... show more

Makes warm water, not necessarily prolonged hot water
Unit works as it should but im using it for hot water in a detached garage sink and once you turn on hot water its burning hot for about 1 second then only gets to be somewhat warm. It still takes the chill off which is nice for washing hands but if you are looking for actual hot water when you only have a cold water line this probably isn't the unit for you ... show more

Great product, very compact size, have not used it yet to rate water temp or flow but so far so good

Works great - mostly
Got 2 of these units 2 replace my standalone gas water heater. Very pleased with how they work - except when they don't. Periodically they simply do not heat up the water - just keeps running through and coming out cold. Actually with one unit it's happened so rarely I probably wouldn't have mentioned it, but the other one fails often enough that it's kind of irritating. I do have a low pressure water system so the water runs slowly, but the unit should still be able to detect the flow and trigger the heater. ... show more
