Abstract
A conventional fireplace with a mantel, a hearth and a chimney has an air intake port and an air exhaust port disposed in the mantel. An air intake fan also disposed in the mantel is connected in series with copper pipe, and the fan is connected to the intake port while the remote end of the pipe feeds the exhaust port. The pipe is routed over the hearth and below the chimney. When a fire is lit in the fireplace, and the fan is turned on, the air passed through the pipe is heated by the fire and blown throughout the room.
