    • Pro Installation

When winter sets in, there are certain rooms that are used less because of cold spots. However, with the consistent and even heat provided by a Rinnai Direct Vent Wall Furnace, you can enjoy comfortable heat anywhere all winter long. Rinnai Wall Furnaces are efficient, easy to install, and the innovative cool-to-the-touch cabinet makes them safe for the whole family.

The Rinnai Direct Vent Wall Furnace’s reputation lies in its ability to extract up to 83% AFUE efficiency through the use of a unique stainless steel heat exchanger, modulating gas valve, and variable speed blower. Whether it’s a whole-house or zone-heating solution, the Rinnai Wall Furnace will provide a comfortable living environment, reduce energy consumption, and lower operating costs compared to a traditional furnace.
