PANEL FOR HEATING

PROBLEM TO BE SOLVED: To provide a panel for heating easy in laying work and having a groove for storing piping for a radiator where the flexible pipe for circulation of a heat medium is laid zigzag with one part in circumferential direction of its peripheral face being fixed to one side of a flexible sheet. SOLUTION: This panel for heating is constituted by combining two kinds of panels of the first panel and the second panel. In the fist panel, even grooves, which lead to the bottom edge at the right lower part of the left one side from the bottom edge at the right lower part of the left one side and run zigzag roughly in parallel between on the left one side, and even grooves, which lead to the bottom edge at the left lower part of the right one side from the bottom edge at the left lower part of the right one side and run zigzag roughly in parallel between on the right one side, are bored, when an oblong plate is divided into eight pieces, with both short sides laid right and left. In the second panel, even grooves, which lead to the bottom edge at the right lower part of the left one side from the top edge at the left upper part of the left one side and run zigzag roughly in parallel between on the left one side, and even grooves, which lead to the bottom edge at the left lower part of the right one side from the top edge at the right upper part of the right one side and run zigzag roughly in parallel between on the right one side, are bored.
