Abstract: A boiler (1) has a combustion chamber (3) associated with a burner (4); a primary heat exchanger (5) for transferring heat from the fumes produced in the combustion chamber (3) to a heating fluid; a fan (7) for circulating the fumes; and a secondary condensation heat exchanger (8) for recovering latent condensation heat from the fumes; the secondary heat exchanger (8) has a pipe (23) wound to form a spiral conduit (24) extending along an axis (A) and in which the heating fluid circulates; and an enclosure (25) having a substantially cylindrical chamber (26) housing the pipe (23) and in which the fumes flow over the outside of the pipe (23).
