Common Problems

The only problem this unit has is the intricate and somewhat tricky installation and mounting procedure. You need to create two new holes at the lower end of the unit to accommodate the EMT connectors since the provided hole and wire clamp are pretty narrow. However, considering that the unit has been specially designed for extremely cold weathers and is appropriate for medium families makes it very feasible choice for indoor usage.


All in all, the product is unique in its technology. The EcoSmart ECO 24 is just another step towards smart water heaters after smartphones. With its innovative ways of heating water, the product is truly a masterpiece and is hard to resist. Although there are missing gaps, the tankless water heater technology is still in its infancy and this means it is still a better device than other heaters out there. The EcoSmart ECO 24 is not simply a water heater; it is something of luxury that you can show off with!! Finally, there is a water heater that is actually “cool”.
