In the composite material 4, a plurality of passages 43 are formed in parallel by the corrugated core material 41 and the flat plate materials 42, 42, and the composite material 4 is laid on the floor material 2 so that the passages 43 are positioned in parallel. Each piece of composite material 4 is, for example, 1500m long so that it can be easily handled during construction.
It is machined to a basic size of m and a width of 500 to 1000 mm, and the appropriate number is laid according to the floor area. FIG. 1 shows a state in which four composite materials 4a, 4b, 4c, 4d are arranged side by side.

Each chamber 7a ~ 7e is a box-shaped molded from a heat-resistant resin having aluminum or corrosion resistance, the import chamber 7a is arranged facing one end of the composite material 4a, the return chamber 7b is the other end of the composite material 4a, 4b, The return chamber 7c is one end of the composite material 4b, 4c, the return chamber 7d is the other end of the composite material 4e, 4d, the export chamber 7
The e is arranged so as to face one end of the composite material 4d. Return chambers 7b, 7c, 7d are adjacent composite materials
The ends of the passages 43 of 4a to 4d are integrally communicated with each other, and the passage 43 is configured as a single continuous passage via these return chambers 7b, 7c, 7d. A heat source introduction pipe 8a is provided in the import chamber 7a.
8a is connected to a heat source supply means (not shown). A duct pipe 8b is provided in the export chamber 7e and is used as a heat source discharge or a circulation passage of a heat source supply means.

In the first embodiment, warm air is used as the heat medium. The warm air is sent from the heating means (not shown) or the like installed outdoors to the import chamber 7a through the introduction pipe 8a, and the return chambers 7b, 7c, and 7d are turned, and the composite materials 4a to 4d are heated. It circulates in the passage 43 and is discharged from the duct pipe 8b of the export chamber 7e (first
