  • Nice affordable water heater
So far, no complaints with this water heater. I replaced a much more expensive unit with this one. The previous unit had the same voltage and breaker requirements, as well as similar water connections, so instillation for me was fairly simple. Performance wise, the Ecotouch heater does great, especially in my house where it typically only runs one fixture or appliance at a time. I have not experienced any cold shots of water while operating like my old water heater used to. Design wise, I like how this unit is set up, it uses a continuous metal water line with the heating element surrounding the water line. All previous on demand water heaters that I've used have had small reservoirs with the heating element submerged within the reservoirs. The Ecotouch design seem less likely to foul up with minerals in my opinion, but time will tell. Very pleased with this water heater so far, wish I'd tried this one first. ... show more

  • Very nice quality works great! I would buy again.
I first was skeptical of the price versus the quality that would end up at my door. They shipped it quickly and I was amazed at the actual size, quality and weight. The unit was very easy to install I just caution anyone looking to buy one to really think on placement. The electric wire is very expensive and you have to run 2 sets of it, I used 6-2 romex x 2 and then had to buy 2- 40amp 220 breakers. Depending on how far from your breaker box is from the unit it may cost you more in wire than the unit itself. Installing the hanger brackets needs to be precise measurement it calls for in the install directions, being off by an 1/8 inch doesn't let it sit tight on the wall. At this time it has been 3 days since I installed it and it works great, very easy to set the temp. I personally like seeing the actual flow rate displayed when it calls for hot water. It brings the water temp up quickly and it holds it at that temp consistently. I understand that the water temp output will be directly affected to the water temp input so we will wait and see what the winter has in store for us but I feel confident that I chose the correct size and proper placement. At this point in time I am very pleased that I purchased this unit and I would recommend it to anyone skeptical on buying one. Just remember buying the proper unit for your area and household size does make a difference. I also needed to contact Ecotouch after I placed my order and they responded quickly and politely. ... show more

  • Digital screen died in less than 6 months
Worked fine when first installed and then the digital screen went out less than 6 months of use. My electrician said it has power going to everything even the digital motherboard but still won't come on at all. Tried to find customer service on Amazon but was unsuccessful and because it's past 90 days I can't just return it. It would be great if they actually had a warranty service department for this company. Not sure what else to do. Would not recommend currently. ... show more

  • Excellent water heater!!
Works perfectly- heats multiple showers at one time, gets too hot at times. We’ve have yet to run out of hot water. Takes up minimal space and looks nice. Reasonably priced-my husband had it installed and heating our water with a couple of hours- would buy again!!!

  • revised, this wasn't working after 3 months
The company did reach out to me and finally connect. It was stressful and was without hot water for about month while working it out. Got the replacement within two days of them sending it out. There was a computer glitch that caused some miss communication but it worked out in the end. The machine was replaced and is working fine now. I didn't do a 5 because of the stressful month without the tank but hey stuff happens and this product has good flow, keeps hot for a long time and is helping on the electric bill. ... show more

  • Great Customer Service
What a great company to work with. I have two of these units; one has worked perfectly, while the other has had an issue after being installed for a while. The reason for the five-star review is the customer service. Throughout email communication, the company provided quick suggestions to resolve the issue. When these suggestions did not work, they promptly shipped me a new unit. It is not installed and working great. ... show more

  • Easy to install
It is saving a lot of space. I’m not sure this tank is correct size needed for a 3 bathroom home. I get lukewarm water in one of the bathrooms. It only goes up to 130 degrees

  • An amazing company!
We ordered a water heater in april and 4 months later it just stopped working. So i contacted the company and their customer service was top notch! I spoke with Elaine via email and she was so friendly and informative. After i sent a clip of our unit malfunctioning, she assured us that we would get a brand new replacement at no cost to us. We have our new heater and the unit itself works amazing. It heats up very fast and the temperature stays consistant. We just happened to get one that didnt want to work but the company was quick to fix the issues and our new one works flawlessly. I would definitely buy products from this company again. They are what companies should be today and they stand by their products! Way to go Ecotouch! ... show more
