Style: 5500W 110V 60AMP
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.

These things are very cost effective! It's just a good value for not water (tankless) for a sink or a mop sink in a work room. The only think to consider carefully is the idea of the amperage needed. Not every switchbox has open 20 or 40 Amp double pole switches available. It's not something a DIY should do without good electrical backup from a qualified electrician. I bought a few of these as I loved the first one. Depending on your needs, this may be your solution. So review 2 of 2: From faucet handle twist to hot water (not warm) in about 4 seconds. The old hot water heater I have takes around 2-5 minutes.

I purchased the 220 Volt, 6000-Watt tankless water heater for our greenhouse because we had no hot water out there and it was miserable in colder months trying to work without hot water. We did have to have this professionally installed, due to it being a powerful 220 volts. We were fortunate to have 220-volt electricity there already and we didn't need to run a new feeder. Getting the water pressure correct and adjusted properly is essential for obtaining the temperature you want. This tank isn't designed to store hot water, but produces it as you need it, so it will take a few seconds to respond to the water running before it produces hot water. However, once it does produce hot water, it will continue to produce hot water until you turn off the faucet. We have tankless gas in the house and were very happy to get tankless in the greenhouse as well. The flow of the water is more than sufficient for our needs. We haven't noticed any increase in the electric bill either, indicating that the water heater is efficient. Tankless water heaters seem expensive at first, but once you realize you aren't paying to keep 50 gallons of water hot when you don't need it, the expense quickly makes sense. We love our tankless and would readily purchase another. Also, we were able to easily mount this on a post as it only measures about 6 inches by 8.5 inches. Lightweight too.

I installed this ECOTINYMACH 6000W tankless electric water heater under my kitchen sink, and overall I’m really pleased with its performance. It heats water on‑demand quickly without the wait you get from traditional tanks, which is especially nice for small spaces or places where you don’t need a huge hot water supply. The compact size fits neatly under a cabinet and doesn’t take up much room, and the ability to switch between Fahrenheit and Celsius on the display makes adjusting the temperature easy. The unit feels solidly built for the price, and the included features like overheat protection and a clear digital readout help give peace of mind while using it. Once running, it delivers consistent hot water for washing dishes and handwashing without noticeable lag. Installation wasn’t too bad if you have basic plumbing and electrical skills. Just be sure you’re comfortable working with a 220V connection or consider having a pro handle that part. I’m giving it 4 stars instead of 5 mainly because installation could be clearer. The instructions were a bit sparse, and if your setup isn’t straightforward it may take extra time or a helper to get everything lined up right. Also, because it’s a 6000W unit, you’ll want to make sure your breaker panel and wiring support it before buying. Great choice if you want a space‑saving, efficient instant water heater for kitchens, small bathrooms, or utility sinks — just plan your installation ahead of time!
