Features
- Note: This model (3kW 120V) electric 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, 240 volts power supply and a 30 amps double-pole circuit breaker are required. Consult an electrician before you order. Thanks

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.

Have owned for 3 months and have yet to get an ounce of even lukewarm warm water from it. It just constantly flashes 22 degrees Celsius. You can turn the dial up to 50 something then it just goes hack to 22 and never even gets warm. It’s been as useful as screen door on a submarine.

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 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!
