ABSTRACT:
A fireplace grate includes a pair of spaced, hollow L-shaped side frames. A first group of hollow flues is connected between the horizontal portions of the side frames. The fire is built on this group of flues. A second group of hollow flues is connected between the generally vertical portions of the side frames. A fan, connected to one of the side frames, circulates air through the frames and flues. The air is heated by its passage through the frames and flues and is exhausted into the room from the other side frame.
