  • the radiator In conventional central heating systems, the radiator first heats the air, which flows from bottom to top through the ribs of the radiator and spreads over this flow throughout the room. Walls and people and objects in the room are then warmed by this heated air. Due to the convection, ie the flow, there are a number of disadvantages. Dust is whirled up and settles down. The concentration of hazardous particulate matter is about 200 times higher in such interiors than on motorways.
