Abstract

A boiler (1;20) comprising a fan (2), an air-gas premixing burner (3), a combustion chamber (4) faced by a combustion head (11) of the burner (3) and a heat exchanger (5; 21) comprising a plurality of tubes (6; 22) in which the water of a heating system runs. The heat exchanger (5; 21) comprises cooling tubes (6a; 22a) arranged in contact either directly or with the interposition of an element (17) formed by high heat conducting material, with a diffuser (15) of the burner (3).
