An enclosed fireplace unit, particularly for heating buildings and sanitary water, constituted by a hearth (3) on the perimeter whereof side walls (4,5a,5b,6a,6b) protrude upwardly so as to delimit a firebox; a hood (19) for connection to a flue is arranged above the firebox. At least one of the side walls of the enclosed fireplace unit is constituted by a first labyrinth-like element (9) which is suitable for the passage of water that arrives from one or more intake ducts (10a,10b) and is connected, in an upward region, to a plurality of hollow plates (15) which can be accommodated in the hood. The hollow plates have a refractory element at the rear and are connected, in an upward region, to a second labyrinth-like element (21) for connection to one or more discharge ducts (23a,23b). <IMAGE> |
