The wide selection of panel radiators includes three main types: one-, two- and three-disc. The heat output of the radiator depends on the number of plates and the size, and thus the size of the surface, which he can heat. All these types of radiators are produced in various widths and heights. Due to their design, they differ in thickness. So in place of a thin one, single-disc, a thicker three-disc can be mounted, radiating more heat energy.
