A heat exchanger for a cooking chamber extends around a ventilator fan of the cooking chamber and has a burner tube connected to one end of a first portion of the heat exchanger and has a reverse bend so a second portion extends parallel to the first portion in the opposite direction. The tube is mounted by the burner and the opposite end so that the reverse bends allows for compensation of thermal expansion in the tube during a heating process.
