<p>The floor heater plate comprises two rectangular or square plates one on top of the other and sealed together along their edges, one or both being arched outwards to form a system of passages for the heating medium. At the plate edge are unions at right angles to their planes for the medium inlet and outlet. The unions are T-pieces (19, 21), each with a lengthwise passage (25, 27) connected by a branch passage (15, 17) to the passage system (13) in the plate (1, 3). The lengthwise passages run parallel to the plate edge, and have pipe unions (39) at each end. At right angles to the plane of the plates, these passages are further apart than they are in this plane.</p> |
