Abstract

A device is provided for heating a room by convection using the heat from a conventional radiation heat source. The heating device further acts as a fireplace guard when the heat source is a fire to substantially prevent sparks or other small particles of combustion from entering the room in which the fireplace is located. The device includes a threshold unit and a plurality of spaced pipes. The pipes are supported by the threshold unit while a screen member such as metal gauze is connected between the pipes. An opening in the threshold unit is adjacent the floor surface of the room in which the heat source is located. The radiation from the heat source raises the temperature of the pipes while relatively cool air enters the opening in the threshold unit and passes into the pipes. The temperature of the air is increased by the heated pipes and exits from the top thereof to heat the room by convection. The threshold unit can comprise a number of separate units which are joined together by a hinge construction so that the length of the threshold unit can be varied and also to permit access to the radiant heat source.
