A fireplace heater includes heat exchange tubes or pipes installed in a fireplace with the lower ends of certain tubes being interconnected by a manifold and the upper ends of the tubes being in communication with a heating chamber in a manner such that cold air from floor level will pass inwardly and upwardly through certain of the tubes and downwardly and outwardly of the manifold from certain of the other tubes for discharge of heated air at or adjacent floor level. The heat exchange pipes or tubes are provided with a grate supporting the logs, a reflector plate extends between the grate and the heating chamber at the upper ends of the tubes and a log retaining plate at the forward edge of the grate. In addition, a heat retaining plate is pivotally attached to the upper heating chamber in a manner to provide a space therebetween so that the heat retaining plate which projects forwardly from the top heating chamber will retain the products of combustion and cause them to pass in more intimate heat exchange relationship to the top heating chamber and around the heating. Additionally, a cover plate rests on top of the front log retaining plate and engages the front edge of the heat retaining plate and a side plate or plates is provided to further enclose the logs or other fuel with a forced draft arrangement facilitating combustion of logs or the like and the device may be used with a panel including a closure door for the fireplace opening, thereby rendering the device substantially universal in installation.
