      I purchased this mini tankless to go under my kitchen sink. My house is a long bungalow and my regular tankless water heater is at the opposite end of the house. I wanted something instant, so I didn’t have to run cold water for long periods in order to get hot water. It works perfectly! Love the dial temperature setting so you can easily adjust if you initially set it too high or too low. Absolutely silent. Can’t believe I didn’t do this years ago!

      House nearly caught on fire due to this unit
      House nearly caught on fire due to this unit, research shows many have had same problem, the heating elements start leaking in a few years, and short out the hot to ground on 1 or more of the three heating elements.

        Bad and Good
        Lasted 37 months and the small crossovers started leaking! Was great to have hot water all the time.... Until we didn't! Started leaking at one of the small vent tubes and quickly progressed! Would not recommend it for reliability.

            Perfect Water Heater
            I installed this back in May of 2018 and still works like a champ with zero issues and have not done a single maintenance on it. But to be fair I also have a water softener which I'm to assume goes a long way towards preventing limescale build-up.

              This is my second time buying this unit because the first one died in less than 5 years. I hope that this one is better.

              SAFETY HAZARD, DO NOT PURCHASE
              The heating element of the unit caught on FIRE and created damage to the house. Luckily we smelled the burn and saw black smoke which prevented from burning down the house. I called EcoSmart three times and they just told me the unit was not under warranty. It is not the issue that the unit is not under warranty, the issue is that the unit is NOT SAFE and could have been a dramatic event if I was not lucky enough to see it. Totally unacceptable!!! DO NOT BUY, SAFETY HAZARD.

                It blew up in three years
                The Eco Smart company was no help. The unit was not in use at the time of the explosion. If I had not been home at the time the entire house would have flooded. They suggested I buy a new one after telling me it was not repairable. I followed the recommended maintenance schedule in the manual. I let them know that I would never be buying another Eco Smart product ever. $500. plus dollars for a water heater that lasted three years. No thanks! I will buy from a different company.

                  May I suggest another brand?
                  FOR ANYONE CONSIDERING THIS BRAND...I purchased my house 2 years ago, this is what we had installed. Two days ago, I found the unit leaking by the inlet temperature sensor was located so I contacted the manufacturer. I was told that I should have been doing yearly maintenance on the heating elements which includes removing them and soaking them in vinegar. This is not in the manual, which simply states to inspect the inlet and outlet values yearly.
