<p>The wall has two water-conducting heating plates (11, 12), which are arranged parallel to one another and are formed from flat tubes (13n) that stand vertically and are arranged in parallel. The tubes are connected in a communicating manner by upper and/or lower manifolds (14, 15) that are arranged horizontally. The manifolds are provided with air passages (16n), which are formed in circular or oval shape and are arranged over a part of an overall length of the manifolds. Heating disks (17) are arranged between the heating plates.</p> |
