Features

  • Note: This model (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 the higher wattage model (6kW 240V) first, which is hard-wired. 240 volts power supply and a 30 amps double-pole circuit breaker are required. Consult an electrician before you order. Thanks
  • Easy to Use: Stylish enlarged LED digital display with knob control, this 3kW 120V point of use water heater is very easy to use. 1 knob for power ON/OFF and temperature adjustment, offering a better user experience than others 3 mini touchscreen buttons.

  • Easy to install, gets really hot, really fast.
Material Type: Celsius Style: 3kW 120V
I had a propane hot water heater installed with my new food truck. I needed something working fast for the health department inspection. I installed this myself with no previous plumbing experience. It's been working really well.

  • Compact water heater works well for small family use
Material Type: Fahrenheit Style: 6.5kW 240V (Built-in Pump)
I requested this for someone who is a bit less fortunate, and the charity I volunteer for is trying to help out. The small, non-functional used RV we got for her and her family constantly needs something fixed, and one of them was the hot water boiler. So I didn’t even blink to request this. First of all, this one is much better than having none for her, so for that, I am already happy with it compared to the cold water she had to live with. It might not get super hot, but it gets warm enough, and especially during this hot weather, it’s been more than enough. If it has any issues during the colder weather, I will definitely update my review. For the material quality, it doesn’t feel too flimsy, and so far it’s been working quite well for the past couple of weeks. It’s also a good size for a small family of two. We also hoped for energy efficiency so she could save as much as possible, and so far, it looks decent in that regard. With the $20 coupon being offered at the time of this review, I would say that as long as it lasts down the road, it will be quite worth the price. ... show more

  • Only warm water.
Material Type: Fahrenheit Style: 6.5kW 240V
Why did you pick this product vs others?: Had to return item. Takes way too long for the heater to kick in and start to see an increase in temperature.

  • Compact and Convenient
Material Type: Celsius 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

  • Hot Water on Demand — Compact Heater, Big Relief
Material Type: Celsius Style: 6kW 240V
This 6kW tankless water heater is a compact powerhouse for sinks and smaller applications. The LED display with knob control makes temperature adjustment intuitive, and it heats up impressively fast — hot water is ready within seconds. It includes multiple safety features like overheat protection, water pressure sensing, and auto temperature modulation, which makes it feel safe and reliable in daily use. The small footprint makes it ideal for under-sink installations, and despite the size, it delivers consistent heat, even in colder seasons. Installation was simple with a basic understanding of wiring, and once mounted, it runs silently and efficiently. Highly recommended for anyone needing hot water on demand at a single point — five stars! ... show more

  • Compact and Efficient But Installation Can Be Tricky
Material Type: Fahrenheit Style: 6.5kW 240V (Built-in Pump)
I installed this LECLOC E65 Pro under my kitchen sink about six weeks ago to get instant hot water for dishes and cooking. While it does deliver on the promise of on-demand hot water, there are some significant considerations before buying. The unit requires 240V/30amp dedicated circuit - not something most people have under their sink. I had to hire an electrician to run new wiring from my panel, which added $400 to the project. The instructions are minimal and assume you know electrical work. The unit is also bulkier than expected, barely fitting in my under-sink cabinet. Make sure you measure carefully - you need about 16" of clearance height. The LED display is clear and the enlarged knob is easy to use, even with wet hands. However, the temperature adjustment isn't as precise as I'd like - it seems to jump in 5-degree increments despite looking like it should be more gradual. The display times out quickly, so you have to tap it to see the current setting. Would've preferred physical buttons that always show the temperature. This works well for its intended purpose - providing instant hot water at a single point of use. But between the electrical requirements, installation complexity, and moderate energy costs, it's not the simple upgrade the marketing suggests. Best for new construction or major renovations where you can plan for the electrical needs. For retrofit situations, consider whether the convenience justifies the installation hassle and cost. ... show more
