Abstract

The invention is directed to an induced draft fireplace including a plurality of outer walls defining an outer housing. The outer walls include at least one outer side wall and an outer top wall. A plurality of inner walls define a combustion chamber. The inner walls include at least one inner side wall and an inner top wall having an outlet opening. A room air circulation channel is defined by and disposed between the outer housing and the inner housing. The room air circulation channel has an inlet and an outlet. A heat exchanger is disposed in the room air circulation channel, and includes an inlet connected to and in fluid communication with the outlet opening, and an outlet. The heat exchanger includes a plurality of walls defining at least two flow paths extending in different directions, the at least two flow paths defining a total change in flow direction within the heat exchanger of at least 180.degree.. A fan having an inlet is connected to and in fluid communication with the heat exchanger outlet. The fan also has an outlet for connection to a flue for transport of products of combustion from the combustion chamber.
