If you have a need for a high amount of hot water then the ECO 36 is the right choice. The ECO 36 is the largest electric tank-less water heater available with our patented self-modulating technology. This smart technology tank-less water heater is ideal for the northern United States, where incoming water temperatures can reach as low as 37 degrees F. The ECO 36 is capable of heating nearly 3.5 gallons per minute at this low temperature. To put that into perspective, it can handle up to two showers running at the same time and never run out of hot water. 

       For homes in the southern United States, the ECO 36 is perfect for large Roman-style and Jacuzzi tubs or high demand of hot water between multiple applications. It can handle up to 6 gallons per minute, which means you can run four showers and a sink simultaneously and never run out of hot water. A digital temperature control allows you to set your temperature in increments of 1 degree, so you can set the temperature to how you like it.
