Rinnai EX Series Direct Vent Wall Furnace

The Rinnai EX Series is a high-efficiency direct vent wall furnace engineered for reliable, energy-efficient zone heating in residential and light commercial spaces. Available in 21,500 BTU natural gas (EX22DTWN) and 36,500 BTU propane (EX38DTP) models, both feature modulating heat technology for precise, comfortable warmth while minimizing fuel consumption.

Drawing combustion air from outside and venting through the wall, the EX Series is ideal for spaces without existing ductwork — basements, garages, cabins, and additions. WiFi thermostat compatibility enables smart control and scheduling for added convenience.
