  • Ecosmart ECO 18 Electric Tankless Water Heater, 18 KW at 240 Volts with Patented Self Modulating Technology

    This Smart Technology electric tankless water heater is configured as a "whole home" model for climates where incoming water temperature is 62°F and above. The ECO 18 is capable of heating over 2.5 gallons per minute, which is the equivalent of one water saver shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 62°F, and an output setting of 105° F. Two showers emitting no more than 1.5 gpm each can be run simultaneously when incoming water temperature is above 70° F. Digital temperature control allows you to set your temperature in increments of 1°. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be mor... [Read More]
