Abstract

A fireplace heating unit comprises a continuous network of hollow tubular members situated in a fireplace. The tubular members absorb heat from the fireplace while air propelled by suitable air moving means passes through the tubular members absorbing heat therefrom. A portion of the air passing through the tubular members may be directed so as to impinge upon the flame in the fireplace and means are provided to control the direction and quantity of the flame-impinging air flow. The remaining air which is not directed onto the flame continues its passage through the tubular members and exits either directly into the room or into a device, such as an oven, for heating other objects. The invention is adaptable for use with either coal or wood fires and in one embodiment is adaptable for use in fireplaces which use a gas jet flame.
