Rinnai's innovative, fully modulating, direct-vent wall furnaces deliver smart, energy-efficient warm air to those hard-to-heat areas such as room additions, guest suites, basements, and garages, as well as mobile homes and high altitude applications. The 7-stage modulating gas valve allows Rinnai wall furnaces to adjust to a room's heating needs, providing comfortable consistent heat. These units are designed to accurately monitor room temperature only 2" off the floor, and are capable of detecting temperature changes as little has half of a degree. Installation couldn't be easier with Rinnai's wall furnaces only requiring a 3" wall terminal hole for flue venting, and a selection of custom vent kits to fit nearly any application.
