      Q:What is the purpose of the WH 27 model with the water flow restrictor?
      by|May 2, 2024
      1 Answer
      Answer This Question

      A:  Hello John, The water flow restrictor is to help ensure the optimal temperature output and overall performance of your tankless water heater. These flow regulators are installed on the outlet connection of your tankless water heater and limit the maximum volume coming out of your unit to a specified flow rate to prevent the exit temperature from becoming too cool.

          Great electrical bill saving.
          I'm happy with my decision to buy the ecosmart water heater unit. I'm replacing it after 10 years of use. Saving me a lot of money in the monthly energy bill. To maintain the water heater the technician from an electrical company recommended to install a water treatment filter for thankless water heater. The city water in my area has a lot of quimical ingredients and this damaged my old ecosmart water heater because it was not protected with a filter.

            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!

              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.

                  Danny,

                  This is great feedback to hear! It sounds like your ECO 36 Tankless Electric Water Heater is performing well. The use of a water softener can indeed help in reducing limescale build-up, which can extend the lifespan of water heaters. Regular maintenance is generally recommended for optimal performance, but it seems like your setup is working efficiently. Thank you for this 5-star review.

                    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.
