A chimney turncap is provided with interior lower drains (14) for guiding condensed water to a collector tray (6) located in the warm zone of the chimney top, whereby the water disappears by evaporation. The hood portion (8) is a semitubular element having a vane (16) placed so as to make the hood assume a position transversely to the wind, whereby the smoke leaves the hood crosswise through the opposite open ends thereof; in this manner the space underneath the hood member is shielded from the direct influence of the wind, such that sufficient heat can be retained for said evaporation. For the same purpose the hood even acts as a reflector for heat radiation from the chimney. |
