The floor of the furnace space [fire chamber] of the heating fireplace is constituted by a horizontal, flat part (7) and the rear wall of the furnace space is constituted in part by a vertical, flat part (8) of a heat exchanger serving for heating water for a hot water heater. Heat is transferred to the water on the sides (38, 39) of the heat exchanger (7, 8) facing the furnace space, and to two fresh air currents on the sides (9, 41) of the heat exchanger (7, 8) facing away from the furnace space. One of these air currents (42) extends under the horizontal heat exchanger part (7) and is fed through an opening (15) therein to the fire as combustion air; the other air current extends in a downdraft duct (22) along the rear wall (8) of the furnace space and further through an updraft duct (25) exposed to the heat of the fire and is fed to the room to be heated as heated, fresh air. |
