<p>A heating group for rooms comprising one first (5) and one second sheet-like element (6) with interposed one third sheet-like element (11), said sheet-like elements (5,6,11) being disposed overlapped each other to form a multi-layer body (2) by the interposition of stratification elements (4) in which: the first sheet-like element (5) is intended to be directed towards the room to be heated the third sheet-like element (11) comprises one electrothermal transducer (15) connectable to a power source to heat all of said sheet-like elements (5,6,11); the second sheet-like element (6) is the outermost on the back of the heating unit (1) and has the outer surface (8) having an emissivity value decreased to form a reflective shield for the radiation emitted in this direction.</p> |
