Longitudinal width _{W 1} and the longitudinal width _{W 2} of the substrate D~F substrate A~C is about half as compared with the total width _W 1 + _{W 2} of both. Therefore, one operator can be located on one of the front side or the rear side of the boards A to C to perform the work of arranging the hot water pipes 3 and 4. Similarly, for the boards D to F, one operator can perform the work of arranging the hot water pipes 8 and 9. The arrangement work of the extending portions of the hot water pipes 3 and 4 in the groove 2 after the substrates A to C and the substrates D to F are butted can be easily performed by one operator.

  Therefore, the production work of the hot water mat 1 is easy, and the production efficiency of the hot water mat is improved.

  In the above embodiment, the substrates A to C and the substrates D to F are each composed of three substrates, but each substrate may be composed of two or four or more substrates.

In the header 30A, the outward main pipe connection port 31 communicates with the left side sub pipe connection ports 33, 34 by the communication flow channels 50, 51, and the return side main pipe connection port 32 communicates with the right side by the communication flow channels 52, 53. It communicates with the auxiliary pipe connection ports 37 and 38. The sub-pipe connection ports 35 and 39 and the sub-pipe connection ports 36 and 40 communicate with each other through the relay channels 46 and 47, as in the header 30 of FIG.

  FIG. 10 is a schematic diagram for explaining the hot water piping arrangement and the flow of hot water when the header 30A is used. In this hot water mat, the hot water sent from the auxiliary pipe connection ports 33 and 34 to the hot water pipes 3 and 4 all flow in the order of the substrates A, B, C, B, and A, and then the hot water pipes 8 and 9 are passed through the substrate D. , E, F, E, D in this order, the relatively high temperature hot water flows first through the substrates A to C, and the hot water having a lower temperature flows through the substrates D through F. Therefore, the heating temperatures of the substrates A to C are higher than those of the substrates D to F.

  In the header 30A, the relay flow passages 46 and 47 are parallel to each other. However, as shown in the header 30B in FIG. 11, the relay flow passage 56 communicates the sub pipe connection ports 36 and 39, and the relay flow passage 57 connects the sub pipe. You may make it connect the connection ports 35 and 40. Also in this case, the hot water pipes 3, 4, 8 and 9 are connected to the respective sub pipe connection ports to form a hot water mat as in the case of FIG. 10.

  In the above embodiment, four hot water pipes (hot water pipes 3, 4, 8, 9) are provided, but six hot water pipes may be provided. An example of such a warm water mat is shown in FIG. 12, and a header 60 used in this warm water mat is shown in FIG.

  As shown in FIG. 12, also in this hot water mat, the three substrates A to C form the first substrate row, and the three substrates DF form the second substrate row. The configurations of the substrates A to C, E, and F are the same as those of the above-described embodiment except that the number of grooves for hot water piping is large.

  As shown in FIG. 13, the header 60 includes a substantially rectangular disk-shaped body portion 60M. A forward side main pipe connection port 61 and a return side main pipe connection port 61r project from one short side of the body portion 60M.

  Sub-pipe connection ports 71 to 76 are projected from the left long side, and sub-pipe connection ports 77 to 82 are projected from the right long side. The sub pipe connection ports 71 to 76 and 77 to 82 are arranged in this order from the front side (main pipe connection ports 61, 61r side) toward the back side.

  In this embodiment, the outward main pipe connection port 61 communicates with the sub pipe connection ports 71, 73, 78 by the communication flow paths 62, 63, 64. The return side main pipe connection port 61r communicates with the sub pipe connection ports 72, 77, 79 through the communication flow paths 65, 66, 67.

  The sub pipe connection ports 74 and 80 are communicated with each other by the relay flow channel 68, and the sub pipe connection ports 75 and 81 are communicated with each other by the relay flow channel 69. The sub pipe connection ports 76 and 82 are communicated with each other by the relay flow passage 70. Each of the relay channels 68, 69, 70 extends in a direction parallel to the short side of the body portion 60M.

  As schematically shown in FIG. 12, six hot water pipes 91 to 96 are installed in this embodiment.

  The hot water pipe 91 has a base end connected to the sub-pipe connection port 71, is arranged in the groove 2 in the order of the substrates D, A, B, and C, and makes a U-turn in the substrate C and is routed in the order of the substrates B, A, and D. The end is connected to the auxiliary pipe connection port 76. The hot water from the sub pipe connection port 33 flows in this order, and then flows to the sub pipe connection port 82 via the relay channel 70.

  The tip of the hot water pipe 94 is connected to the sub pipe connection port 82. The hot water pipe 94 is arranged in the groove 2 in the order of the substrates D, E, F, makes a U-turn in the substrate F, is routed in the order of the substrates E, D, and is connected to the auxiliary pipe connection port 77. The hot water sent from the sub pipe connection port 82 to the hot water pipe 94 flows through the hot water pipe 94 in the above order and returns to the sub pipe connection port 77.

  The hot water pipe 95 has a base end connected to the sub-pipe connection port 78, is arranged in the groove 2 in the order of the substrates D, E, and F, makes a U-turn in the substrate F, and is routed in the order of the substrates E and F. It is connected to the auxiliary pipe connection port 81. The hot water from the sub pipe connection port 78 flows in this order, and then flows to the sub pipe connection port 75 via the relay channel 69.

  The tip of the hot water pipe 92 is connected to the sub pipe connection port 75. The hot water pipe 92 is arranged in the groove 2 in the order of the substrates D, A, B, and C, makes a U-turn in the substrate C, is routed in the order of the substrates B, A, and D, and is connected to the auxiliary pipe connection port 72. The hot water sent from the sub pipe connection port 75 to the hot water pipe 72 flows through the hot water pipe 72 in the above order and returns to the sub pipe connection port 72.

  The hot water pipe 93 has a base end connected to the auxiliary pipe connection port 73, is arranged in the groove 2 in the order of the substrates D, A, B, and C, and makes a U-turn in the substrate C and is routed in the order of the substrates B, A, and D. The end is connected to the auxiliary pipe connection port 74. The hot water from the sub pipe connection port 73 flows in this order, and then flows to the sub pipe connection port 80 via the relay flow path 68.

  The tip of the hot water pipe 96 is connected to the sub pipe connection port 80. The hot water pipe 96 is arranged in the groove 2 in the order of the substrates D, E and F, is turned in the substrate F to be routed in the order of the substrates E and D, and is connected to the auxiliary pipe connection port 79. The hot water sent from the sub pipe connection port 80 to the hot water pipe 96 flows through the hot water pipe 96 in the above-described order and returns to the sub pipe connection port 79.

  In the hot water mat 1, the hot water delivered from the auxiliary pipe connection port 71 or 73 flows through the hot water pipe 91 or 93, the relay channel 70 or 68, and the hot water pipe 94 or 96 in this order over all the substrates A to F. In addition, the hot water sent from the sub-pipe connection port 78 flows over all the substrates A to F in the order of the hot water pipe 95, the relay channel 69, and the hot water pipe 92. Since the flow path length (pipe length) through which hot water flows is large in this way, the pressure loss given to the flowing hot water becomes appropriate, and an excessive amount of hot water is prevented from flowing through the hot water pipes 91 to 96.

  In addition, in this embodiment, the hot water flowing through the hot water pipes 91, 93, 94, and 96 flows through the substrates A to C first and then through the substrates D to F, and the hot water flowing through the hot water pipes 92 and 95 is It flows through the substrates D to F first, and then flows through the substrates A to C. In this way, the order of flowing hot water is opposite in the hot water pipes 91, 93, 94, 96 and the hot water pipes 92, 95, so that the substrates A to C and the substrates D to F are heated substantially evenly.

  Also in the case of manufacturing the hot water mat shown in FIG. 12, the substrates A, B and C are butted and the hot water pipes 91 to 93 are arranged in the groove 2 of each substrate as shown in FIG. At this time, both ends of the hot water pipes 91 to 93 are respectively extended from the groove 2 of the substrate A by a predetermined length (a length that reaches the sub pipe connection port of the header 60).

  Further, the substrates D, E, and F are butted against each other, the hot water pipes 94 to 96 are arranged in the groove 2 of each substrate, both ends of the hot water pipe 94 are connected to the sub-pipe connection ports 77 and 82, and both ends of the hot water pipe 95 are sub-portions. The hot water pipe 96 is connected to the pipe connection ports 78 and 81, and both ends of the hot water pipe 96 are connected to the auxiliary pipe connection ports 79 and 80. In the board D, the hot water pipes 3 and 4 are not arranged in the leftmost six grooves 2.

  After that, the rows of the substrates A to C and the rows of the substrates D to F are juxtaposed and abutted against each other. Next, the extended portions of the hot water pipes 91 to 93 extending from the substrate A are respectively arranged in the leftmost six grooves 2 of the substrate D, and both ends of the hot water pipe 91 are connected to the auxiliary pipe connection ports 71 and 76. Both ends of the hot water pipe 92 are connected to the sub pipe connection ports 72 and 75, and both ends of the hot water pipe 93 are connected to the sub pipe connection ports 73 and 74.

  In this way, the step of arranging the hot water pipes 91 to 93 on the substrates A to C and the step of arranging the hot water pipes 94 to 96 on the substrates D to F can be performed separately.

  Another example of the header 60 is shown in FIG. In the header 60A, the forward side main pipe connection port 61 communicates with the left side sub pipe connection ports 71, 72, 73 by the communication flow channels 61a, 61b, 61c, and the return side main pipe connection port 61r communicates with the communication flow channel 62a. The right sub-pipe connection ports 77, 78, 79 are communicated with each other by 62b, 62c. The sub-pipe connection ports 74 and 80, the sub-pipe connection ports 75 and 81, and the sub-pipe connection ports 76 and 82 communicate with each other through the relay channels 68, 69, and 70, like the header 60 of FIG. ..

  FIG. 15 is a schematic diagram for explaining the hot water piping arrangement and the flow of hot water when this header 60A is used. In this hot water mat, the hot water sent from the auxiliary pipe connection ports 71 to 73 to the hot water pipes 91 to 93 all flow in the order of the substrates A, B, C, B, and A, and then the hot water pipes 94 to 96 are passed through the substrate D. , E, F, E, D in this order, the relatively high temperature hot water flows first through the substrates A to C, and the hot water having a lower temperature flows through the substrates D through F. Therefore, the heating temperatures of the substrates A to C are higher than those of the substrates D to F.

  The above-described embodiment is an example of the present invention, and the present invention may have other forms. For example, in the above-described embodiment, the header is arranged on the leftmost substrate D, but the header may be arranged on the rightmost substrate F.
