To provide a method of laying a floor heating heat sink at a predetermined position on a floor surface of a general dwelling, an assembly dwelling, a commercial building, or a hotel, and a method of laying the floor heating heat sink while inspecting the presence of any damage of a heat medium tube upon fixing the floor heating heat sink disposed at a predetermined position on a floor surface.
A heat medium tube 3 including a conductive layer 4 is disposed in a groove 2 formed meandering in a heat insulating member layer 1, and a surface of the heat insulating member layer 1 is coated with a surface coated layer 6 including a conductive thin plate, and further there is formed a current detection circuit, to which a current detection device 8 is connected, between the conductive layer 4 of the heat medium tube 3 and the conductive thin plate of the surface coated layer 6, and furthermore a floor heating heat sink is fixed at a predetermined position with a nail, detecting a conduction state of the circuit with the current detection device 8.
