This patent describes heat recovery apparatus. It comprises: a tubular element the interior surface of which defines an unobstructed flow passage, the element being structured at its opposite ends to facilitate its installation to form a part of ductwork through which products of combustion and/or other fluid embodying heat energy May escape from a furnace or the like, a helical coil of tubing wrapped around the exterior of the tubular element in heat transfer contact therewith, opposite ends of the tubing being projected to serve respectively as the inlet for fluid which is to be heated in passage therethrough and the outlet for the delivery of the so heated fluid therefrom, a protective shell surrounding and capping the coil of tubing and positioned in a circumferentially and substantially equidistantly end spaced relation thereto. The shell being apertured for projection therethrough of the opposite ends of the tubing to be connected with the form a part of a fluid handling and conditioning system. The tubular element being elongated relative to and extending beyond the respective ends of the protective shell.
