Challenger Floor Furnace

The Cozy Challenger Floor Furnace provides warm, even heat through the natural convection of circulating warm air. Cozy’s scientific design ensures a high volume air exchange–as much as three to five times per hour–guaranteeing uniform temperatures throughout your home. The Cozy Challenger features a factory-mounted control with built-in pressure regulator and 100% safety pilot. The millivolt controls require no electricity to operate, so losing heat during a power failure is never an issue.
