I am totally impressed with this tankless water heater. If you want to know the ugly truth, I use it along with a bidet to keep things more comfortable in the water closet. It supplies, warm water quickly enough to avoid that initial shock from the past. I think it would work great in many other applications such as pet washing or kid washing LOL I remember as a child, being full of mud and my mom, taking the garden hose and spraying us kids down. It was Midsomer, but still, it felt a little chilly at first. This would alleviate some of that concern as well. You know, with today's children and all LOL It is easy to install, and it doesn't look awful. It is a lot smaller than I realized when placing my order. It doesn't leak or malfunction in any way that I can tell. I think the cost/benefit ratio is pretty good as long as it remains durable. I tend to take pretty good care of my things, and this will remain indoors, of course. I expect it will last a very long time as long as it doesn't get flushed. My order came well packaged and ready to go. I am very happy with this product and highly recommend it 😎 I sure hope you found this a help. Thanks👍🏼 ... show more

    • easy to install
**Review Title:** Exceptional performance and highly efficient compact design for tight spaces **Review Body:** I am absolutely thrilled with the overall performance and energy efficiency of this ECOAPTUNIT electric tankless water heater. Given its remarkably compact footprint, it serves as the perfect, high-quality solution for anyone struggling with limited under-sink cabinet space or tight plumbing configurations. The installation process was incredibly intuitive and straightforward; the manual provided clear, easy-to-follow instructions that made the entire setup process quick, professional, and entirely hassle-free. Once fully installed, the heater has performed with outstanding reliability, consistently providing a steady flow of hot water exactly when it is needed. I especially appreciate the intuitive digital display, which allows for effortless toggling between Fahrenheit and Celsius temperature settings, providing a level of user-friendly customization that is frequently missing from competing units. Whether you are looking to renovate a small bathroom or simply need to add a dedicated, efficient hot water source to a utility area or workshop, this unit is a fantastic, well-engineered choice. I can confidently and highly recommend this to anyone in search of a dependable, space-saving, and user-friendly hot water solution that truly delivers on its promises. ... show more

Great value and love that it’s small and compact to fit perfectly under any sink. We are thinking about installing in our RV or maybe bathroom. Great that it’s electric makes it easy to install no need to worry about gas.
