Heat exchanger with at least one essentially horizontal pipe through which a fluid, especially water, flows, and heated on the outside by a heat-exchange fluid, especially combustion gases. In order to prevent the temperature falling below the dew point in places on such an exchanger, provision is made for the pipe (1) to be internally fitted, at places, with an insulating element (2, 2', 5). <IMAGE> |
