A device for radiance heating of rooms (A) comprising a burner (2) with a combustion chamber (5), a chimney (4) in fluid connection with said chamber (5) for ejecting the combustion products of said burner (2), heating means (3) in operative connection with said combustion chamber (5) and configured to produce a heat carrier fluid comprising at least one gaseous phase, wherein said heating means (3) comprise a circuit (9) with an outer heat-conducting radiating surface (12) designed for direct contact with the room (A) for radiant heating thereof. The combustion chamber (5) has an outlet (8) for said combustion products directly connected to said radiant circuit (9), and said chimney (4) comprises a heat recuperator (16) for at least partial recovery of sensible heat and latent heat from the combustion products of said burner (2), said recuperator (16) comprising a secondary circuit (17) for a recuperator fluid to flow therethrough, which can be associated with a heating circuit (9; 21) susceptible of at least partially returning the recovered heat to the room (A). |
