A manifold for a heat exchanger including a plurality of substantially identical heating tubes. The manifold has front and rear walls. The rear wall has therein a plurality of inlet ports, each of which is adapted to be connected to the outlet of one of the heating tubes, the inlet ports being generally equally spaced along the rear wall in the upper half of the manifold. The rear wall also has therein a plurality of outlet ports, each of which is adapted to be connected to the inlet of one of the heating tubes, the outlet ports being generally equally spaced along the rear wall in the lower half of the manifold. The front wall has therein a water inlet opening into both the upper manifold half and the lower manifold half, and a water outlet spaced horizontally from the water inlet and opening into both the upper manifold half and the lower manifold half. The manifold also includes an involuted web which extends between the front and rear walls, which is attached to the front wall above the water inlet and below the water outlet so as to separate the inlet and the outlet, and which is attached to the rear wall along a horizontal line separating the inlet and outlet ports so that water entering through the water inlet communicates only with the outlet ports and water entering through the inlet ports communicates only with the water outlet.
