Our Experience with the Electric Tankless Water Heater
Efficiency and Convenience: This electric tankless water heater delivers instant hot water with a robust 3000W power output, perfect for quick use in tight spaces like my RV kitchen or bathroom. The one-touch operation makes it effortless to adjust temperature settings, and the compact design (11x7x20cm) fits seamlessly under sinks without taking up much room. It heats water efficiently, raising the temperature by up to 45°F at 0.3GPM, tho I noticed the flow rate affects the final temperature-higher flow means slightly cooler water. while not ideal for showers (which need at least 1.8GPM), it works well for handwashing or quick bathroom needs. The premium materials, including 304 stainless steel lining and 316L heating pipes, ensure durability, and the IPX4 waterproof rating gives me confidence it can handle unexpected leaks or damp environments safely.
Design and Safety: The sturdy ABS shell and uni-corrosion brass interface add to its resistance against wear and tear, while the multiple safety features (leak, dry-heating, electrical isolation, sensor faults, and grounding protection) make it reliable. I appreciated the automatic standby mode,which keeps the unit ready for use without constant power drain. However, installation requires careful attention-vertical mounting is crucial to prevent heating element issues, and tightening pipe connectors with Teflon tape avoids short circuits. The 10AWG wire gauge and 31A breaker are essential, as using lower specs caused flickering during first use.

Installation and Setup: A Seamless Integration into Our Space
This compact electric tankless water heater delivers instant hot water without the need for a bulky tank, making it perfect for small spaces like my RV kitchen. I was impressed by how quickly it heated water-within seconds, even at lower flow rates. The one-touch operation is a lifesaver, and the automatic standby mode ensures water is always ready when I need it. Its IPX4 waterproof rating and multiple safety features, such as leak and dry-heating protection, give me peace of mind during use. The 3000W power at 110V provides strong performance, though I had to ensure my electrical setup included a 31A breaker and 10AWG wire to avoid issues.
Constructed with durable 304 stainless steel and 316L heating pipes, it feels sturdy and corrosion-resistant. The ABS shell and brass interface add to its reliability,and the sleek design fits neatly under my sink. However, I noticed that the flow rate directly affects water temperature, requiring some trial and error to get the desired output.While it's great for sinks, showers aren't supported as thay need a higher flow rate than this unit can handle. Installation was straightforward but required careful attention to the vertical placement and Teflon tape on connectors to prevent malfunctions.
it's a convenient and space-saving solution for on-demand hot water, but the technical setup and installation steps are non-negotiable.The pros include fast heating, safety features, and portability, while the cons involve strict electrical requirements and limited flow capacity for certain uses.

Performance and Efficiency: Reliable Hot Water on Demand
This compact electric tankless water heater delivers instant hot water at 3000W, making it perfect for small spaces like my RV kitchen. It heats water efficiently, raising the temperature by 45°F at 0.3GPM or 27°F at 0.5GPM, and allows precise control via flow rate adjustments. The IPX4 waterproof rating and multiple safety features-like leak and dry-heating protection-give me confidence in its reliability, especially during outdoor trips.Its one-touch operation simplifies use, though I had to adjust the flow carefully to avoid overheating.
Constructed with premium materials including 304 stainless steel lining, 316L heating pipe, and a durable ABS shell, the unit feels sturdy and well-built.The vertical installation requirement and need for 10AWG wiring (with a 31A breaker) mean it's not a DIY-pleasant setup, but the included screws and manual make the process manageable. It's ideal for bathrooms or apartments but lacks the high flow rate needed for showers, which was a minor downside during testing.
Powerful yet space-saving,this heater offers quick access to hot water without the bulk of customary models. However, its reliance on specific electrical and plumbing configurations can be a hassle. The automatic standby mode ensures continuous hot water when needed, but users must be mindful of flow rates to optimize performance. it's a great solution for on-demand heating in tight spaces,though careful planning is essential for installation.
