In addition, thanks to its compact size, you can place Eco 11 almost anywhere inside your home.

EcoSmart Eco 11 Water Heater Features

On Demand Hot Water

The EcoSmart Eco 11 can heat up water to 105 °F nearly instantly. As soon as the water reaches this temperature, the heater will provide hot water to several pipes. This water heating system comes with a digital temperature control which allows the user to change the temperature in one-degree increments on the water heater itself. All the controls of the heater are designed to provide the user maximum control over the unit and assure consistency in producing hot water.

However, when the incoming water temperature is below 67 °F, the tankless water heater’s performance will be impacted. This could lead to a lower maximum water temperature or a reduced flow rate of hot water. You can check the map below to see what the incoming water temperatures are in your area.

Because of this, we recommend using a professional to install the water heater. You can find a licensed plumber on Amazon’s home services marketplace, which makes it easy to purchase the appliance online and make sure it’s installed properly.
