  • radiators of the type mentioned which are also referred to as Porterradiatoren, are often used, on the one hand to be used as a heater and on the other also visually enrich the environment. In such a case, such radiators are also marketed as visually different demanding products in the trade. Usually, such radiators are once provided with flow and return connections that connect directly to the headers and introduced into the wall. More sophisticated radiators are often designed as radiators with center connection, in which case a panel is used, which conceals the connection area of the radiator together with all components, such as a Schustabelektrik, an infrared remote control receiver unit and the like, behind. For such a radiator, a completely different construction in the lower part of the radiator, usually a tubular radiator, be sought in order to meet the mounting requirements for a center connection.

That is, although the terminal portions are quite important for achieving the object of the present invention, they can be implemented in a variety of ways. The same applies to the connection lines of the connecting section. These too can be diversified. This is also dependent on whether a panel radiator or a tube radiator should be connected.
