A method of combustion of a gaseous fuel in a heating appliance (1; 22) provided with at least one burner (15; 29; 34, 35, 36; 38), comprising mixing said gaseous fuel with a preestablished quantity of air to obtain an air-fuel mixture, supplying said mixture to the body of said at least one burner (15; 29; 34, 35, 36; 38), which is provided with a diffuser (19) on which openings (18) are made through which said mixture passes, causing the combustion of said mixture in order to generate flames (20; 32; 33; 34; 37; 42), the method further comprises irradiating heat towards said flames (20; 32; 33; 34; 37; 42) and a region directly surrounding said flames (20; 32; 33; 34; 37; 42). A heating appliance (1; 22) provided with at least one burner (15; 29; 34, 35, 36; 38) fed with a mixture of gaseous fuel and air, said at least one burner (15; 29; 34, 35, 36; 38) being provided with a diffuser (19) having openings (18) through which said mixture passes and with means (21) to cause the combustion of said mixture and the formation of flames (20; 32; 33; 34; 37; 42), the heating appliance further comprises heat irradiating means (47; 45, 46) which are capable of irradiating heat towards said flames (20; 32; 33; 34; 37; 42) and a region directly surrounding said flames (20; 32; 33; 34; 37; 42).
