On the plate (5) inside are one or more tubes (11) which are lowered into the channels (7) with conductive contact between them and the plate for transmission of heat to the latter. Hot water flows through the tubes, and at the back of the plate is a heat-insulating material. The space formed by the plate, the panel rear side, long sides and short ideas is wholly filled with foamed cellular plastic. Between the tubes and the cellular plastic is a foil (13) which covers the tubes and is fixed to the plate on opposite sides of the channels. The foamed cellular plastic partly forms a heat insulation at the rear of the tubes and the plate, and partly forms a rigid constructional component in conjunction with the hollow space limiting walls and the tubes. |
