    • Works great. Draws alot of current, wire proper.
This was the perfect item for adding hot water to my washing machine that was outside, and to impractical to plumb hot line. Setup was easy. I just wired a short cord to plug, I will mention, it draws alot of amps. Keep electrical lines short. Worked great. Prefilter will make it last longer, keep the mineral deposits from blocking up internals. ... show more

    • Instant hot water - exactly what we needed
This tankless water heater arrived at the perfect time. Our 50‑gallon water heater just can’t keep up with multiple people using the showers and sinks in the morning - someone always ends up with cold water if they get a late start. In some parts of our home, we even have to run the water for a couple of minutes just to get it warm. This unit completely solved that problem. It provides instant hot water at our sink, and the difference is amazing. The heater itself is a great value, though hiring an electrician for installation was a bit pricey, but worth it. One important note: despite what some posts say, it requires a 60‑amp circuit breaker, not 40‑amp. I haven’t received my first electric bill yet, but I expect it to be slightly higher. Even so, the convenience and the water savings make it more than worth it. We no longer waste water waiting for it to heat up in our 2nd bathroom. The water can get extremely hot - up to 131°F (scalding). 120°F is plenty for us and probably more energy efficient so we’re keeping it at that setting. Honestly, tankless heaters like this should be standard in all homes. They save water, reduce wait times, and make mornings so much easier. Great product, and I’m really glad I found it. ... show more

    • Instant Hot Water
I installed this in my farthest (from the water heater) bathroom sink. Finally I can have hot water without wasting water. This thing heats the water fast enough for a quick rinse of my toothbrush, which previously I would just use cold water. Installation is a breeze if you have room under the sink, which I did, and the size of the unit makes it even easier to get into a cabinet. I'm pretty good at installing this kind of stuff so I didn't really need the instructions, which frankly are pretty lacking, but straightforward and as expected/. ... show more

    • Instant hot water, cuts down on waste
Our water heater is on the other side of the house, so we always have to wait a while to get hot water to wash dishes. Not only does this deliver instant hot water, it saves water because you are not just wasting water while you wait for it to heat up. The hot water that comes out is hot enough to start using immediately. ... show more
