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.

works perfectly, relief pressure rating is accurate

Style: C-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!

Style: C-3.5kW 120V
This 3.5kW 120V under-sink tankless water heater is a compact and efficient solution for getting hot water at a bathroom or kitchen sink. The enlarged LED digital display is easy to read, and the knob control makes temperature adjustment simple. It heats water on demand which is faster and more efficient than a boiler tank. The overheat protection and IPX4 water resistance add safety and durability, especially for use in damp environments. Installation is quite simple with simple water hose attachment but will require eletrcial hookup.

Style: C-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.

This is actually super small and lightweight. It probably would be good for one room not like a whole house as other TWH would be. It was pretty easy to install. Water stays hot. I’d recommend it.

This heater did not heat water more than lukewarm. Didn’t work for us.
