Efficient operation
The thermostat-controlled blowers in Cozy furnaces draw air from outside and release it through a concentric vent, using natural convection to retain warm air and distribute it evenly throughout the home. Some Cozy models, such as the Challenger Conventional-Vent unit, perform up to five high-volume air exchanges per hour. Enjoy maximum efficiency with Cozy models such as the Blue-Flame and Infra-Red Vent-Free, which are 99.9 percent efficient, or the Hi-Efficient Direct-Vent, which has over 80 percent AFUE efficiency.
Operational during power outages
Cold weather months are when you need reliable heating the most, especially if ice or storms cause the power to go out. Self-energizing millivolt controls on Cozy furnaces require no power to operate, allowing the furnace to work even if the power fails. Enjoy this feature on the Direct-Vent, Challenger, Gravity Conventional-Vent, and other Cozy models.
