Abstract

A gas-fired boiler (10) provided with: a burner (16) arranged in a firebox (18); a gas/water heat exchanger (20) arranged around the firebox and provided with a system of flat pipes (22) for the conveyance of the burnt gases (14) arranged in a radial pattern and provided with lateral recesses (106; 24) for noise reduction; a mixer (28) for supplying a gas-air mix to the burner, structured so that the pressure of the gas-air mix is constant regardless of the amount of mix supplied.
