A heat exchanger, comprising a box-like body which delimits inside it at least one heat exchange chamber and has at least one inlet and at least one outlet for the passage through the chamber of combustion products along a preferred path. The box-like body defines at least partly in its side walls at least one duct for feeding a fluid and inside the heat exchange chamber elements are provided and are associated with the supply duct in order to increase the thermal efficiency of the heat exchanger. The heat exchanger comprises a plurality of distinct modular elements which are mutually interconnected in order to define the box-like body. Each modular element may comprise at least one portion of the heat exchange elements, of the supply duct and of the chamber.
