Eccotemp i12 NG Indoor Tankless Water Heater

Eccotemp i12 NG Indoor Tankless Water Heater


The Eccotemp i12-NG has a new revolutionary design, making it unlike any other tankless water heater on the market today. This model features sleek black tempered glass paneling, fully automatic temperature controls for precision, and a touch screen with an LED temperature display that shows output temperature and GPM flow. Rated at an impressive 3 GPM, the Eccotemp i12-NG Tankless Water Heater is a natural gas fired, indoor model designed for small to medium hot water production where you need more than one hot water application at the same time. The Eccotemp i12-NG is perfect for vacation cabins, cottages, and smaller homes.

The i12-NG comes with a horizontal stainless steel vent kit, ready to install and with its 120-volt UL listed power cord powering the internal exhaust fan and digital display.  It only pulls about 2 watts idle and 1.07 Amps during operation, making it an ideal energy efficient appliance.

The i12-NG offers a 35-40 degree Fahrenheit temperature rise when operating at flow rate of 3 GPM and a 77-degree Fahrenheit temperature rise at 1.5 GPM.
