The flat energy element consists of the heat insulation (1), the heat-conducting layer (2), the heat conductor (3), the flat panel (4) with its hollow spaces (5) and, when used as a solar collector, with the absorption layer (7). The device makes possible energy-saving heating of buildings of all types, as well as economical combination with air-conditioning and ventilation installations, and can also be used as a solar collector. <IMAGE> |
