The Eccotemp FVI12 Indoor Natural Gas Tankless Water Heater is one of the most advanced indoor models of the Eccotemp tankless line. The included Eccotemp 3" category III, stainless steel, UL listed Horizontal Vent Kit makes installation a breeze. Additional venting may be required based on your installation. The Eccotemp 3" Horizontal Vent Kit Includes a termination hood with backflow preventer, 90-degree elbow, 12" straight pipe, wall thimble, and appliance adapter.

Rated at 4.0 GPM with a temperature rise of 38 degrees and 80,000 BTU per hour, the Eccotemp FVI12-NG can meet your hot-water needs! Eccotemp's advanced 0.7 GPM low flow ignition technology allows users to enjoy endless hot water without experiencing cold spots. Manual temperature controls allow the temperature to be set and regulated at the front control panel, and not your sink or shower.

We recommend the Eccotemp FVI12-NG for smaller single-family homes, apartments, condos, or cabins. Using 1-2 hot water applications simultaneously is a breeze with the Eccotemp FVI12-NG. With our upgraded PCB (Product Control Board) performance and an all-new gas modulating valve, consumers can experience best-in-class temperature performance at a price anyone can afford. 

The compact, wall-mounted Eccotemp FVI12-NG has a 110/120-volt UL listed power cord that powers the internal Exhaust Fan, Digital Display and PCB.
