ABSTRACT:
A foldable floor heating panel can be folded longitudinally and laterally. The foldable floor heating panel includes several small plate-like members of a rectangular plan configuration, which are arranged longitudinally and laterally so as to be adjacent to each other. A flexible thin plate is attached to upper surfaces of the small plate-like members so as to allow longitudinal and lateral folding. Heat carrier flexible tube passages are provided in longitudinal and lateral folding portions of the panel so as to leave some play, and folding margin members are provided at the lateral folding portions. Fit-in members are attachably and detachably provided in respective heat carrier flexible tube passages with some play.
