ABSTRACT OF THE DISCLOSURE: This boiler is enclosed in a sealed casing forming a fore-heath which surrounds it on all sides while providing thereabout a space into which the combustion air arrives It is characterized in that said combustion air is injected under pressure into a space which surrounds the boiler. Furthermore, according to a particular embodiment of the invention, the exchanger is divided into two parts in the vertical direction by a refractory floor, which enables it to play, in the upper part which contains the burner(s), its conventional role as an exchanger, and in the lower part where its receives cold water, a role both as an exchanger and as a condenser. The burner can have interesting struc- tural features in order to reduce the pressure drop of the combustion air flow or to allow the burner ramp to be easily fitted and refitted. Furthermore, the fins of the exchanger can be arranged in an advantageous manner.
