<p>The boiler with water tubes comprises a casing (3), in which are mounted a series of vertical tubes (5) serving as a surface for heating and exchange between the furnace (2) and the water to be heated which circulates in the tubes (5), and two, respectively upper (3a) and lower (3b) collectors, into which the tubes (5) open. The boiler (2b) comprises two independent water circulations, one effected through the upper collector (3a) forming an exchanger/mixer, to which the outward (13) and return (14) pipes of the heating circuits are connected, and the other effected by thermosiphonic action inside the tubes (5) and the upper (3a) and lower (3b) collectors.
