A condensing boiler (1), comprising a framework (2) which supports a boiler body (3) provided with a furnace (4). The furnace forms internally a combustion chamber (15), which is functionally connected to a burner (6). The boiler body (3) further has; between a lateral containment shell (7) and the furnace (4), a water compartment (8), which is affected by a stream of water to be heated. The combustion chamber (5) is connected, at one of its ends, to a gas deviation chamber (9) suitable to direct the combustion gases toward a heat exchanger (100) provided with at least one flue (10), which is connected, at its inlet end (10a), to the gas deviation chamber (9). In the flue (10), the sensible heat and latent heat of the combustion gases are transferred to the water stream to be heated. The flue (10) is arranged inside the water compartment (8) and ends, with its outlet end (10b), in a gas and condensation collection chamber (11), which is connected to a stack (12) for conveying the gases and to a condensation discharge duct. The furnace (4) is arranged above the heat exchanger (100) and the framework (2) comprises two upright supporting plates (2a, 2b), which face each other and are mutually substantially parallel and support the furnace (4). The flue (10) is connected, at its opposite ends, to the upright supporting plates (2a, 2b) so that its longitudinal axis is oriented substantially at right angles to the upright supporting plates (2a, 2b), which are inclined with respect to the horizontal in order to arrange the inlet end (10a) of the at least one flue (10) at a higher level than its outlet end (10b).
