    (54) Heating device


    (57) The invention relates to a heating device.
    A first object of the invention is to embody a heating device with a combustion space having at least one free side, such as an open hearth, or optionally a free-stan­ding heater, such that it possesses a high yield. Another object is the embodying of this heating device such that in addition to use as a free-standing heater it can also be used as insert system for an open hearth.
    These objects are realized with a heating device characterized by a tilted, substantially U-shaped heat ex­changer open to the front for heating air at the fireplace, this heat exchanger being provided with a lower heat exchanger part onto which can be laid solid fuel, for example a number of pipes laid adjacent to one another, which lower part con­nects onto a standing heat exchanger part, for example a number of pipes located at an interval from one another, such that the heat exchanger bounds the combustion space.
