ABSTRACT:
A heat exchanger is disclosed herein for placement in the firebed of a standard fireplace which includes a heat box having an inlet and an outlet separated by a heat chamber having a series of baffles included for conducting an air flow across the panels of the heat box. The panels of the heat box define the heat chamber and are in close or immediate proximity to the fire in the firebed so that the heat induced into the panels is transferred to the air flow conducted past the panels by the baffles. A blower is coupled to the box inlet by a suitable conduit so that ambient room air is provided to the heat chamber while a discharge conducts the heated air flow back into the room.
